FEMALE-Length 9 mm.; eyes converging below; malar space w r y short, linear; facial foveae well developed, subtriangular, rounded above, broad medially, more pointed below; antennae ferr

The three genera irl this family t h a t occur

in the eastern United States a r e quite di-

verse in size of the i~lcludecl species, a s well

as in t h e i r appearance and habits The most

distinctive common feature is the short,

broadly tl-uncate, bificl or hilobed glossa in

which they resemble the sphecoid wasps

more c!osely thnn they d o the other bees I n

the males, the virlse!!a of the genital arma-

ture is composed d : clistinct cuspis and

dipitus, ihe latter being :~~.ticulalted in some

of the included forms, and tile inner oppos-

Emendation

This is p r i a i a ~ i l y a ncotropic:ll group of

bees, with but two ?pec.ies k ~ l o ~ i r n from the

United State?, one of the121 occurring in the

southwest and the c ~ t h ~ r ill the southeast

The included :,pecies a r e large and densely

pubescent, ou: species beinp about as large

as a medium-sized bumble-bee The glossa is

conspicuously bjlohed, ~:\c!i Io',e being elon-

gate, sle~lder, acute apically and well corer-

ed with short setae The scopa is well de-

ve!oped on the t r n ~ h a n t e ~ s , femora and

tibiae of the hind legs, the hairs very long,

slender, copious and densely plumose The

pygidial plate is large and weli developed in

the female, while in th_e male i t is evident but not distinct

Carolina to Georgia and Alabama; Septem-

ber

FLOWER RECORDS-Aureolaria sp

and Trichostema dichotemum

There is much to learn regarding the

distribution and habits of this bee It seems

to be primarily matinal, so f a r as the time

of flight is concerned, and both sexes have

been collected on Trichostema around sun-

rise Males, however, have been collected in

late afternoon or a t dusk, visiting both

Trichostema and Aureolaria I t was thought

that i t might be nocturnal, but the flowers

which i t visits, a t least so f a r as positive

records show, are closed during the night,

which would seem to preclude any nocturnal

visits I t occurs, apparently, only in the

sand ridge areas of the Coastal Plain in

the Southeast

Colletes Latreille, 1802 Histoire naturelle des

fourmis p 423 Type: A p i s succincta Lin-

of the thorax, the more basal segments of the hind legs and to some degree the venter

of the abdomen also suggest a primitive or generalized condition The most distinctive and reliable character is the recurved form

of the 2nd recurrent vein of the front wing The 1st submarginal cell is nearly equal

to the 2nd and 3rd combined I n size, species

of Colletes approximate that of the honey- bee, some of them being somewhat larger and others smaller Usually they are rather conspicuously pubescent, and many species have prominent apical bands of hair on the abdominal segments

Biological notes on a few of the species have been pub1ished.l They are soil-nesting, making tunnels of varying depths which are humming with activity during the brief period of flight Species are either vernal

or autumnal, and only in the more northern latitudes where the summer is very short, are they found in flight during the mid summer period

This species is so closely related to kin-

with difficulty No reliable or constant dif- ference between the females of the two spe- cies can be given, and i t is best to rely on the males for positive identification In that sex the one apparently constant difference

is in the form of the retracted 7th abdom- inal sternum The figures (Plate 9) will show the difference I n kincaidii the discs

of this plate are relatively broad a t the base, abruptly expanded above the base, and this area is densely setose to the inner mar- gin In contrast, the discs in eulophi are somewhat narrower a t base, are much more gradually expanded above toward the apex, and the inner half of the base is devoid of setae

In all other characters the description of both sexes in kincaidii will serve equally well for eulophi

ed on disc of basal segment, becoming closer and more minute and obscure on the more api- cal segments; apical margins of terga de- pressed, reddish on the more apical segments beneath the entire white fasciae; pubescence entirely whitish, without dark admixture, disc- a1 pubescence obscure, very short and erect DISTRIBUTION-Recorded only f r o m Florida, w h e r e i t i s i n flight d u r i n g April
