64 Mr. T. D. A. Cockciell — Descrqjtioas and 



S . — The two stripes of mesothorax broader, broadly 

 reacliing anterior margin, and more or less connected with 

 large patches of pale hair whicli occupy the anterior lateral 

 corners ; pleura densely covered with hair ; teeth at sides of 

 scutellum somewhat longer and appreciably curved inwards ; 

 spurs of middle and hind legs black ; black band on first 

 abdominal segment longer, rounded instead of obliquely 

 truncate laterally, and without an anterior projection breaking 

 the basal pale band ; angles formed by lateral processes of 

 band of second segment less acute ; apical plate rounded. 

 The antenna? and labrum are entirely black, and there is no 

 red about the thorax. 



? . — Antennae black ; anterior lateral corners of mesothorax 

 with ])ale patches ; teeth at sides of scutellum smaller; pleura 

 hairy, the lower part densely punctured. Wings hardly so 

 dark ; spurs black -, apical pale band of first abdominal 

 segment more broadly interrupted, but basal band not 

 interrupted. 



Hah. E,io Ruidoso, New Mexico, about 6700 ft., at flowers 

 of Erigeron macranthus, July 27, (J [C. H. T. Townsend) ; 

 Kociada, New Mexico, Aug. 8, ? {Gockerell). 



ISEPEOLUS, gen. nov. 



(^ . — Similar in appearance and markings to Epeolus^ but 

 differing as follows : — Third antennal joint very long, longer 

 than the scape ; apical half of galea slender and elongated; 

 labial palpi very long (the last two joints minute as usual) ; 

 axillar teeth present but rounded, blunt ; b. n. falling tar 

 short of t.-m. ; submarginal cells subequal, but the third the 

 largest ; the second large, square, a little shorter below than 

 first or third, receiving first r. n. near its end ; third s.m. 

 receiving second r. n. near its end ; outer side of third s.m. 

 strongly bulging ; marginal cell with its apex obliquely 

 truncate, the tip away from the costa, the part of the lower 

 edge joining the s.m. cells a trifle shorter than the part 

 beyond ; apex of abdomen rounded, without a projecting 

 plate, the upper surface of it covered with fine hair. The 

 maxillary palpi appear to be quite as in EpsoUis. Claws 

 bifid; a very long pulvillus, as long as the claws, with a 

 black apical disk. 



For years 1 have had this insect marked " Leiopodus ? " ; 

 but having seen the type of Leiopodus in the British Museum, 

 it is evident that Isepeolus is very distinct by the oval abdo- 

 men, large but not especially peculiar hind coxa?, second s.m. 

 a little narrower below than first, &c.
