subglobular, decreasing gradually in length and each except the 

 last with a rather well marked, short pedicel. The enlarged por- 

 tion of the segment bears near 

 its base a nearly uniform row 

 or whorl of rather stout, 

 slightly curved setae, and the 

 remainder of the distal surface 

 is sparsely ornamented with 

 longer, niore curved setae aris- 

 ing from distinct setigerous 

 punctures, each segment with 

 a distinct though not conspicu- 

 ous transverse ridge with 

 white punctures at regular in- 

 tervals on the basal third and 

 another at the distal border of 

 Xhe enlargement. Palpi com- 

 posed of five segments, basal 

 short, second longer, third a 

 little shorter than the second

 segments of male, much enlarged (Original) 



distinct distally, its posterior fork uniting with the margin at the 

 posterior third. Halteres with a slender, yellowish pedicel, distal 

 portion strongly capitate, semitransparent, whitish. Legs yel- 

 lowish, first tarsal segment of posterior leg very short, second much 

 produced, third about half the length of the second, fourth a 

 little shorter than the third and the fifth half the length of the 

 fourth; claws simple, empodium well developed. Length ^ inch,
