Genus PASITES. Latr. 

 Pasites pilipes, n. sp. 



Chestnut-brown, polished ; sides of face, clypeus, collar, tubercles, two spots 

 on pleura, postscutellum, and narrow bands on abdomen, white; hind legs of 9 

 densely pilose; wings hyaline, costo-apical margin fuscous. 



Female. — Chestnut-brown, polished, clothed with pale pubescence ; 

 face flat, highly polished, impunctured; sides of the face obscurely, and 

 the clypeus, whitish; cheeks and labrum densely pubescent; antennae 

 piceous, paler at base. Thorax indistinctly punctured, pleura and me- 

 tathorax rather densely clothed with silvery-white pubescence ; a line 

 on the collar, tubercles, two spots on pleura, two small spots on scutel- 

 lum. and the postscutellum, white; scutellum slightly subbilobate; 

 tegulse brown, the outer margins pale. Wings hyaline, faintly tinged 

 with fuscous, slightly iridescent, the costo-apical margin broadly fuscous. 

 ] egs chestnut-brown, clothed with pale pubescence, which is long and 

 dense on the posterior tibiae and tarsi ; posterior coxae dilated and flat- 

 tened, with a whitish spot at tip. Abdomen broadly ovate, convex, 

 polished, rather densely clothed with short pale pubescence on the sides 

 and apex; on the middle of the first, second, fourth and fifth segments 

 above, a narrow, rather uneven, whitish fascia, that on the fourth seg- 

 ment interrupted on the middle ; on each extreme side of the third 

 segment a short, narrow, whitish line; apical segment truncate, densely 

 clothed with fuscous pubescence; beneath chestnut-brown, immaculate. 

 Length Si lines; expanse of wings 62 lines. 



Male. — Resembles the female, except that the abdomen is longer, not 

 so broad, and pointed at tip as in the males of Noma da; the posterior 

 legs are not densely pilose as in the $ . Length 3 lines ; expanse of 

 wings 5J lines. 



Collection. — Ent. Soc. Philad. Two specimens. 



This species has much the general appearance of a Nomada, and in 

 in the % specimen, the only difference I can see is, that the anterior 

 wings have only two submarginal cells, instead of three; but in the 9 • 

 the form is more robust, and the hind legs are densely pilose, which is 

 never the case in the females of Nomada. 



Genus EPEOLUS. Latr. 

 Epeolus Wilsoni, n. sp. 



Black; face, cheeks, collar, posterior margin of mesothorax, two lines on its 

 disk anteriorly, angular mark on pleura, most of metathorax, large indented 

 mark on each side of first abdominal segment and bands on the other segments 

 interrupted on the disk, yellowish; wings fusco-hyaline ; tibiae, tarsi and apex 

 of abdomen dull fulvous. 



Male. — Velvety-black; frontal orbits, clypeus, labrum and mandibles.
