Hippiscus olancha Caudell, an Apparently Unde- 



described Grasshopper from California 



(Orthop., Acrididae). 



By A. N. CAUDELL, of the Bureau of Entomology, U. S. 

 Department of Agriculture, Washington, D. C. 



The species here described has for some time been repre- 

 sented in the collection of the United States National Museum 

 by four specimens, three males and one female, kindly donated 

 by Mr. Wm. T. Davis, of Staten Island, New York. The 

 description of this handsome grasshopper is now ventured, 

 because after comparison with the Scudder Collection of 

 Orthoptera and a quite thorough search of the literature on 

 this genus of insects, it is believed to be an undescribed form. 



Hippiscus olancha n. sp. 



$ holotype; Olancha, California, April 24, 1917. 



Head moderate in size, ashy gray in color, with obscure fuscous lat- 

 eral variegation, the occiput blackish ; eyes moderately prominent, red- 

 dish brown in color ; antennae more than one and one-half times as long 

 as the pronotum, slightly flattened toward the apex and gently curved, 

 the color blackish in about the apical two-thirds the basal third black 

 and ashy-banded, the basal segment wholly light ; frontal costa smooth, 

 deeply dentate at the median ocellus, the lateral margins slightly ele- 

 vated at and below the ocellar depression and continued almost to the 

 clypeal suture; the sides of the frontal costa are broadly expanded 

 opposite the ocellus and then converge to where the frontal costa meets 

 the scutellum of the vertex, where it is scarcely more than one-half as 

 broad as at the ocellar expansion; scutellum of the vertex with very 

 moderately elevated margins, the narrowing anterior portion rounding 

 into the frontal costa, from which it is separated by a shallow trans- 

 verse depression with a slight median logitudinal carina ; f oveolae some- 

 what longer than broad, anteriorly pointed, the sides slightly rounded. 



Pronotum ash-gray, with numerous dark maculations ; disk flat, with 

 very moderately elevated rugosities, a depression on each side of the 

 very gently elevated median carina on the anterior part of the posterior 

 lobe, which is fully twice as long as the anterior lobe, the median carina 

 being cut by two sulci much anterior to the middle, the carina oblit- 

 erated between these sulci, and anterior to them scarcely attaining the 

 anterior truncated margin of the pronotal disk ; posterior margin of 

 disk rectangiilate ; lateral lobes slightly higher than long, not noticeably 

 narrowed mesially, the lateral sulci extending down across them as dis- 

 tinct depressed lines; lateral carina distinct and fairly prominent on the 

 posterior lobe, not, or barely, indicated anterior of the transverse sulci.
