60 Mr. T. D. A. Cockerell — Descriptions and 



Robertson, and is new to New Mexico. The species lias a 

 wide range eastward. Mr. N. Banks sends me specimens

Triepeolus agaricifer^ sp. n. 



(J . — Length 9 ram. or rather more. 



Black, with the markings orange-huff, all the abdominal 

 hands of the same colour ; legs red, the coxge and trochanters 

 black, anterior femora black above except at apex, middle 

 femora mainly black above and beneath, hind femora black, 

 with a broad red stripe above ; hind tibiae with a large black 

 patch behind ; spurs red. Middle of mandibles red ; labrum 

 black ; hair of face orange ; antennas black, the third joint 

 with a large red mark in front ; vertex very coarsely punc- 

 tured; mesothorax very coarsely punctured, with two very 

 distinct stripes which reach the anterior margin, which latter 

 has no light border; markings of thorax as usual; teguloe 

 and most of tubercles red ; scutellum entirely black, strongly 

 bigibbous, with short but very distinct lateral teeth ; lower 

 part of pleura showing a black (but not entirely nude) area, 

 which is densely and coarsely punctured. Wings with the 

 apical margin broadly dark fuliginous; stigma red; nervures 

 fuscous; second s.m. much narrowed above. Abdomen 

 broad, with all the bands broad and perfectly entire, except 

 the basal one on the first segment, which is rather broadly 

 interrupted; black median mark on first segment transversely 

 fusiform, with obliquely truncate sides, much shorter than in 

 T. helianthi^ but not triangular as in T. lunaius ; band on 

 second segment with a broad low prominence on each side in 

 front, but no projection forming an angle; apical plate 

 black, narrow. 



Looks at first sight like a small T. lunatus, but easily 

 separated by the characters italicized. 



Hah. Beulali, New Mexico, August (Cockerell) . 



The name agaticifer is derived from the black mark on 

 the first abdominal segment, which, when the insect is seen 

 from the front, looks like an agaric. 



Epeolus argyreus, sp. n. 



^ . — Length about 8^ mm. 



Black, but largely covered with the usual pubescence, 

 which on the abdomen is pale cinereous with a yellowish tint, 

 on the thorax above the same, but on the face and pleura 

 (both of which are entirely and densely covered) brilliant
