From these measurements it is evident that the type is distinctly 

 under the average in size, while the allotype is considerably over the 

 average for the female sex, both showing in certain proportions the 

 minimum and maximum proportions, respectively, for their sexes. 

 The selection of the type and allotype was based solely on the con- 

 dition of the specimens, so no size factors were considered in the 

 matter. It is apparent from the above evidence that there is con- 

 siderable individual variation in size in the species. 



Color Notes. — As none of the material belonging to this species^ 

 has been stuffed, we are compelled to take the colors found at their 

 face value, although doubtless some have altered very materially. 

 The pattern of both sexes consists of a more or less uniform dorsal 

 color involving a variable portion of the occiput, dorsum of the 

 pronotum, dorsal portion of the lateral lobes of the pronotum and 

 dorsum of the abdomen, and a pale lateral color which involves the- 

 face, gense, ventral portion of the lateral lobes, and lateral aspect of 

 the abdomen, the latter color always (cf) or frequently (9) modi- 

 fied in extent and tint. 



Male. Dorsal color varying from prout's brown to clove bromi, 

 most decided near its lateral borders on the abdomen. Lateral color 

 varying from buckthorn brown to dresden brown, the ventral half
