 exce|)ting summit, tlavous, more or less infuscated or clouded v ith 

 olivaceo-fuscous, the summit brownish testaceous, with very variable 

 blackish niarkiugs, sometimes consisting of a median i)osterior dash, 

 sometimes of a pair of divergent stripes, sometimes longitudinally 

 combed with black; there is a broad and greatly widening black stripe 

 behind the whole eye; front of fastigium very broadly sulcate; frontal 

 costa and whole face very sparsely punctate, the former broadly sulcate 

 as far down as and including the ocellus; antennae tlavous, sometimes a 

 little infuscated. Pronotum tiavo- testaceous above, the metazona dis- 

 tinctly olivac* ous, the median carina heavily marked in black; upper 

 half or rather more of the lateral lobes with a piceous baud, occasion- 

 ally obsolescent on the metazona, and often distinct only at its upper 

 and lower margins, esi>ecially the former, the remainder tlavous; abdo-

In the I'nited States National Museum there is a singb' femalr from Texas in 

 Tvbich the tegmina extend a litMe more tlian halfway to the tip of the abdomen and 

 are of a very different shape, the basal third gradually and normally broadtning. 

 but beyond taperir.g rather rapidly, so that the rounded tip is narrower than the 

 base; it \>oks like an abuoimal development.
