260 NEW NORTH AMERICAN MELANOPLI (oRTHOPTERa) 



Hesperotettix pacificus capillatus^ new geographic race (Plate XXIX, 



fig. 1.) 

 1897. Hesperotettix pacificus Scudder, Proc. U. S. Nat. Mus., xx, p. 61. (In 



part.) [ 9 ; San Buenaventura, California.]^ 



The present geographic race and pacificus pacificus Scudder, 

 both show considerable size, tegminal and color variation. Con- 

 sidering the fact that, as is usual in the present genus, the male 

 genitalia show no differential characters, the characterization of 

 these races is difficult. The series at hand, however, offer such 

 convincing proof that separation must be made, that we feel no 

 hesitancy in describing the present race. 



This race is clearly a depauperate condition of the species and 

 will probably be found locally distributed along the Californian 

 coast, from Monterey Bay southward to the Santa Barbara Chan- 

 nel. The size averages smaller, the surface is not as smooth and 

 the hairy covering is generally more pronounced, the antennae 

 average distinctly shorter and the caudal femora are slightly less 

 enlarged proximad, than in pacificus pacificus. 



Both races develop a green, pale brown and dark brown color 

 form. In the green condition of the present race no broad red- 

 dish annuli of the cephalic and median femora and broad pre- 

 genicular reddish annulus of the caudal femora are found, which 

 markings are usually met with in this phase of typical pacificus, 

 and pacificus capillatus, fiu'ther, is normally much less brilliantly 

 colored. In both green and brown phases this race usualh^ has 

 the characteristic buffy markings less conspicuous and reduced 

 to a greater extent than is usual in pacificus pacificus. 



Type. — cf' ; Del Monte, Monterey County, California. Sep- 

 tember 9 and 10, 1910. (Rehn and Hebard.) [Hebard Collection, 

 Type no. 484.] 



Size small for the genus, form slender, surface well supplied with minute 

 pilose hairs, more thickly than is normal in pacificus pacificus. Eyes api)reci- 

 ably deeper than infra-ocular portion of the genae. Sulcationof the fastigium 

 and frontal costa moderately decided, slightly more pronounced than in paci- 

 ficus pacificus. Antennae short and stout for the genus, little longer than 

 combined length of head and pronotum, shorter and stouter than in pacificus 



^ In allusion to the normally more hairy condition found in this race, when 

 compared with the typical race of the species. 



* An additional female from Scudder's series, in the Hebard Collection, 

 labelled in pencil "Los Angeles, Cal. 1888," is referable to the present race. 

 In this case, we believe the labelling to be incorrect, or inaccurate.
