182 Cockerell — Neio American Bees. 



median apical transverse area ; remaining segments with perfectly black 

 hair, but a good deal of long white hair at extreme sides of fifth ; hair of 

 venter dark reddisb-fnscous, white at sides ; first ventral segment with a 

 pair of broad oblique bright orange bands. In all respects very close to 

 M. tepaneca Cr., from which it is known by the black hair of lower part of 

 pleura in front, the much darker flagellum, the entirely white hair of face, 

 the white outer scopa of hind legs, etc. It also nearly agrees with 3f. comp- 

 toldes Rob., but will be easily known from that by the color of the hair on 

 hind tarsi, and other characters. 



3/«/f.— Length about 11 mm.; clypeus lemon yellow with a black spot 

 on each side ; mandibles with a large yellow basal spot ; antennae long, 

 third joint a little longer than second, tlagellum bright ferruginous beneath ; 

 hair of cheeks white, of face rather dull white, of occiput very long and 

 yellowish, of vertex without black ; hair of thorax above fulvous, of pleu?-a 

 dull yellowish white; teguUe red, dark basally ; second abdominal seg- 

 ment with a narrow median entire white band ; third and fourth segments 

 with extremely broad basal bands of white tomentum, from which spring 

 scattered black bristles ; hair of fifth and following segments entirely black ; 

 legs with fulvous hair, the short hair on inner side of hind tibiae fuscous; 

 abdomen broader than in 3f. tepaneca or M. kallslroemise. Easily known 

 from tepaneca by the white (not yellowish-stained) bands of third and 

 fourth abdominal segments, the absence of long white hairs at sides of 

 fifth, the dark hair on inner side of hind tibije, and the dark apices of 

 wings. By the color of the abdominal bands it resembles M. kalhlrnemix 

 var. phenacohh'n, but it is a stouter insect, and the hair of the liind legs is 

 quite differently colored. 



Habitat— G'A\\e»ioi\, Texas. May. F. H. Snow 2077 and 2080. 



Eniphoropsis rugosissima sp. nov. 



Female. — Like E.floridana (Smith), but a little larger and more robust ; 

 wings less darkened, and the second submarginal cell more narrowed 

 above; hair of occiput yellowish-white (black in ftondana), a tuft of pale 

 hair also on each side of antennte; clypeus coarsely rugose ; extreme sides 

 of fifth abdominal segment with some long glittering white liairs ; scopa of 

 hind tarsi shorter and denser, brown-black or very dark puri>lish-fuscous. 

 The hair of the cheeks and the pleura (except the extreme upper part) is 

 black ; that of the thorax above is pale ochraceous, not at all mixed with 

 black. 



Habitat. — Nevada (no other particulars known) ; in coll. Amer. Ent. So- 

 ciety; loaned through Mr. Viereck. The E.floridana used for comparison 

 is from Georgia (Cresson collection). 



Xenoglossa utahensis sp. nov. 



Female.— About 14 mm. long, broad ; head, thorax and abdomen en- 

 tirely rather dark reddish-brown or ferruginous ; legs bright ferruginous ; 

 pubescence very pale ochraceous, becoming dull white on labrum, cheeks,
