short in tho inosial dorsal aspect, 

 three pi-ecediiig sei(inents. 



Eyes rather proniiiieiit, about twiee 

 defined blackisli-brown ocelli. 



First antenna? slender, extending to a sliort distance beyond 

 the middle of the third joint of the second. 

 Basal joint stout, twice as loncf as broad ; 

 second joint elongate, slender ; third a little 

 longer than broad ; fourth about half as long 

 as the second. Second antennae about 2"5 mm. 

 long, the first joint broader than long, armed 

 with minute spinules ; second joint three 

 times as long as the first ; it is evenly curved, 

 with the superior border concave and the 

 inferior convex, the distal half is swollen and 

 bears a few spinules on the lower border and 

 two strong spines on the upper ; third joint 

 longer than the second; it is curved through- 

 out its length, dilated distally, and has a 

 single spine at the superior angle ; fourth 

 joint longer than the third, slightly curved 

 and somewhat thickened near its sjoineless 

 extremity ; fifth and sixth joints equal in 

 length ; the two combined are about half the 

 length of the third. Mandibles straight with a well defined 

 molar tubercle, a broad spine-row and a tridentate cutting edge. 



The third joint of the first pair of legs 

 has a small spinule on the middle of the 

 superior border ; the seventh joint is but 

 little curved and is shorter than the sixth. 



Second joint of the second pair of legs 

 more than three times as long as broad ; 

 lower border straight, armed with ten or 

 tweh'e short, stout spinules ; upper border 

 curved, Avith a long spine in the middle. 

 The third joint is a little longer than broad, 

 much wider above than below, with three 

 or four spinules on the inferior border and 

 a long spine on the middle of the upper. 

 Fourth joint longer than the third, twice 

 as long as broad and apically dilated ; 

 the inferior border has three unequal spinules, and the upper 

 terminates in a long spine. Fifth joint about one-third longer 

 than the two pi-eceding combined, ai-med on the inferior border 

 with scattered spinules ; the superior distal third is somewhat 

 swollen. Sixth joint a little longer than the fifth, and per-
