Family ACRIDIDAE 

 Subfamily Cyrtacanthacrinae 



PATANGA PINCHOTI, new species 



Collected on Eiao, September 28, 1929. 



This species runs out to the genus Patanga in the l^ey given by 

 Uvarov in his revision of the group Cyrtacanthacrini.^^ Some re- 

 lation to the genus Austracris is indicated in the somewhat strongly 

 retrorse prosternal spine, and it is indeed possible that it really 

 should be referred there. This species is named in honor of the noted 

 leader of the expedition, Hon. Gifford Pinchot. 



Descriptio7i. — Head with the face rather strongly retreating; eyes 

 almost but not quite twice as high as long, the anterior margin 

 straight; fastigium of vertex flat, transverse diamond shaped, broadly 

 rounding into the frontal costa, which is equally broad throughout, 

 or barely narrowed at the ocellus, and with the slightly elevated 

 lateral margins just reaching the clypeus; antenna about twice as 

 long as the pronotum. 



Pronotum with a veiy low but persistent median carina, the lateral 

 carinae indicated only posteriorly; the pronotal disk cut by three 

 transverse sulci, the posterior one situated about the middle; the 

 anterior margin of disk almost straight, very slightly and roundly 

 angulate, while the posterior margin is obtuse-angulate, the tip entire 

 and narrowly rounded. The surface of the pronotal disk is punc- 

 tated on the metazona, the rest dully rugose. Prosternal spine sub- 

 cylindrical, apically pointed and the whole directed rather decidedly 

 backward, though normally not nearly reaching the mesosternum; 

 in a couple of somewhat crushed specimens almost or quite reaching 

 the sternum. Tegmina rather slender, apically slightly narrowing 

 and curved very gently backward, the apical third more transparent 

 than the basal portion ; wings hyaline with black venation. 



Posterior femora rather slender and with the apical third or more 

 with the margins subparallel. 



Cerci of the male slender, gently flattened laterally, tapering grad- 

 ually to a point, gently curved inward, the whole about five times as 

 long as basally broad and reaching the tip of the supraanal plate. 

 Supraanal plate sulcate above in the basal half or slightly more, the 

 lateral margins straight and gently converging to near the triangu- 

 larly pointed tip, where they terminate in a lateral shoulder. Sub- 

 genital plate of male elongate, sharply pointed and directed upward 

 and backward, extending decidedly beyond and slightly above the 

 tip of the supraanal plate. Valves of the ovipositor moderately 

 recurved.
