pacificus. Caudal margin of disk of pronotum obtuse-angulate produced, with 

 immediate angle rather sharply rounded. Tegmina small elongate-oval pads, 

 costal margin curving distad more sharply than sutural margin, forming an 

 acute point directed dorso-caudad. 5 Genitalia showing no features of differ- 

 ence from pacificus pacificus. Caudal femora moderately enlarging proximad, 

 appreciably less robust there than in pacificus pacificus. 



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



Differs from the type in the following features. Size larger, form moderately 

 stout for the genus. Sulcation of the fastigium and frontal costa weaker and 

 broader. Antennae even shorter, distinctly shorter than the combined length 

 of the head and pronotum, distinctly shorter and stouter than in this sex of 

 pacificus pacificus. Caudal margin of pronotum forming a more obtuse angu- 

 lation. Genitalia as in this sex of pacificus pacificus.

The female from San Buenaventura shows divergence toward pacificus 

 pacificus only in having the caudal femora slightly heavier than is normal in 

 the present race. 



A single male of pacificus pacificus from Marcel, Kern County, California, 

 shows some divergence toward the present race in the somewhat narrower 

 tegmina and caudal femora, but in all other respects is typical. 



Coloration. — Dark brown, lighter brown and yellowish green phases of colora- 

 tion are found in pacificus capillatus. All of the males are brown and only a 

 few show some recession in coloration; eleven of the nineteen females are 

 brown, of the same shade as the paler males. In this phase the narrow buffy 

 medio-longitudinal dorsal line and narrow bar or bars 8 of the postocular por- 

 tion of the genae and prozonal portion of the lateral lobes of the pronotum are 

 distinct but not conspicuous. The external faces of the caudal femora are 

 suffused proximad, mesad and in the pre-genicular area with dark brown, this 

 sometimes greatly reduced, but in the majority distinct, the median and distal 

 suffusions running across the dorsal surface as broad and distinct transverse 

 bands. 



5 This feature varies individually in degree, but the entire series shows smaller 

 and narrower tegmina, with apices less evenly rounded, than is shown in the 

 considerable series of pacificus pacificus at hand. 



6 This is an individually variable feature. In the majority of specimens a 

 narrow bar of buff is found below the broad dark bar of the prozonal portion of 

 the lateral lobes of the pronotum. In others a trace of buff is shown also 

 above the dark bar, and in some this is developed into a second bar of buff, as 

 wide as or even wider than the ventral buff bar.
