Allotype.— 9 ; same data as type. [Hebard Collection.] 

 Similar to the male t>i)e except in the following features. Size decidedly 

 larger, form robust. Pronotum similar (the series showing that the carinae 

 and sulci are often weaker in this sex). Tegmina elongate ovate, slightly 

 broader and separated by a wider interspace (1.4 to 1.9 in the allotype and 

 paratypic females.^)

The Spring Mountains series shows that, in the two thousand five hundred 

 feet of vertical distribution through which this race was there found, the 

 individual size remains unaffected. 



Color pattern obsciu'e. Type with head light pinkish cinnamon, occiput 

 and cheeks minutely flecked with mummy brown, the former with a medio- 

 longitudinal band of that color, which widens caudad, this band varying to 

 weak or wholly obsolete in the series; a broad postocular band of nuunmy 

 brown on each side, this varying to very weak in the series. Pronotiun light 

 pinkish cinnamon suffused and flecked with mummy brown, the post-ocular 

 bar continued and occupying the dorsal half of the lateral lobes, but weakly 

 defined, usually bister fading to snuff brown on the metazonal portions and 

 frequently with a buffy fleck at the terminal portions of the principal sulcus. 

 Tegmina light pinkish cinnamon suffused with bister, this least in dorsal 

 portions and frecjuently deepening to blackish proximad near the costal 

 margin. Abdomen light pinkish cinnamon, the proximal tergites heavily 

 and extensively marked with black laterad. Antennae and ceplialic and 



^The females from Crestline have the pronotal carina and sulci more decided 

 than in any from the typical series and the tegmina witler, broad oval, so that 

 the interspace between these averages less (.3 to 1.1 mm.). The Crestline 

 material probably shows in these features incipient geographic racial dilTcr- 

 entiation, as yet not sufficiently advanced to warrant nominal recognition. 

 The differences discussed show convergence toward borckii pacijicus, but the 

 examples in all other respects are typical of the present race.
