40 Mr. T. D. A. Cockcrell on 



Townsend, which has passed as E. compactas, Cresson, in New 

 Mexico, having been so identified by Mr. Fox. It may have 

 been included by Cresson among his specimens oi compact uf^; 

 but it surely is not the species described under that name. 

 From the description (Tr. Am. Ent. Soc. vii. p. 89) it differs 

 thus: — Not especially compact, the abdomen at least twice as 

 long as broad ; pleura with the upper part densely white- 

 hairy, the lower densely and coarsely rugoso-punctate, nearly 

 freefrom pubescence ; pale (hair) markings white, not buff; 

 abdomen strongly pruinose all over with tine pubescence, so 

 that the nsual black markings, while indicated, are more or 

 less obscured, the black surface being nowhere exposed ; the 

 apical white bands on the first four segments are broad and 

 entire, and are somewhat emphasized by the fact that the 

 apical margins of the segments, beneath the pubescence, are 

 white ; the transverse dark band (grey because pubescent) 

 on the first segment is much produced and quite attenuated 

 laterally. Labrum, mandibles, and first three joints of an- 

 tennae ferruginous, the flagellum brownish grey with a sort of 

 silvery sheen above, ferruginous beneath ; anterior middle of 

 mesothorax with a white hair-patch, no separate stripes ; 

 scutellum faintly bilobed, black with two reddish spots, lateral 

 teeth red, quite sharply pointed, not extending so far as 

 scutellum ; tegula? bright orange-ferruginous. Wings rather 

 short, faintly dusky, with an apical cloud ; stigma and nervures 

 of basal half of wing ferruginous, nervures of apical half dark 

 fuscous ; marginal cell rounded at end, appendicuhite. Legs 

 ferruginous, the femora strongly infuscated, spurs light ferru- 

 ginous ; silvery area on last dorsal segment of abdomen 

 inconspicuous. 



Epeolus heulahensis, sp. n. 



$ . — Length 7 millim. 



Black with yellowish-white markings due to pubescence ; 

 face, including clypeus, covered with silvery-white appressed 

 hair; mandibles and labrum dark ferruginous ; eyes strongly 

 converging below ; eyes (dry) grey ; antennae long, brown- 

 black ; end of scape and the two following joints ferrugi- 

 nous beneath ; tubercles and tegulse ferruginous ; scutellum 

 entirely black, faintly bilobed, tlie lateral teeth very short ; 

 thorax, including pleura, covered with pubescence, except 

 disk and anterior margin (except two broad short stripes) of 

 mesothorax, anterior half of scutellum, metathoracic enclosure, 

 and a spot on each side of raetathorax, which are bare and 

 consequently black; legs clear red, including the spurs; an- 

 terior femora except knees, and anterior tibiae except ends,
