 subequal and stouter than the following. 

 Epistomal suture fine but distinct; body stout, the antennae short; pro- 

 thorax wider than the head Oanasciis 



Epistomal suture completely obsolete; antennre very long, filiform and 



cylindrical; prothorax narrower than the head Saiidytes 



11 — Epistomal suture distinct; body stout, oval; ^lead not constricted at base;

ELOWrS n. gen. 



Ill this genus the body is oblong, moderately convex, opaque, 

 coarsely, densely sculptured and clothed with short confused 

 pubescence intermixed with longer and more erect hairs. The 

 head is deeply constricted and strongl}^ sinuate at base, the 

 fourth joint of the maxillary palpi moderately large and in the 

 form of a right-angled triangle, and the last joint of the labial 

 veiy large, slightl}^ transverse, suboval, truncate at apex and 

 deeply concave, with the surface minutel}^ granulose and sen.si- 

 tive beneath. The eyes are large, deeply emarginate, coarsel}' 

 faceted, conspicuously pilose and distant from the base; antenuiie 

 long, more or less thick, cylindrical and roughly sculptured, with 

 the second joint transverse, short, as wide as the first but wider 

 than the third and obliquely truncate at base, the last joint 

 obliquel}^ pointed or bent. 



The middle coxjb are well separated, the posterior subcontigu- 

 oiis, the basal process of the abdomen rather acute, the basal seg- 

 ment of the latter having the dividing suture visible in the mid- 

 dle very near the base and almost tangent to the acetabula. The 

 posterior tibiae are devoid of terminal spurs, but have instead a 

 terminal tuft of j'ellow setae externally ; the basal joint of the 

 hind tarsi is extremely long, bent toward base and finely subcari- 

 nate beneath.
