ecarinate sides of the pronotum and very broad male claspers 

 will distinguish this species. 



Holotype (No. 387), male, from El Dorado County, in col- 

 lection of the California Academy of Sciences. 



Allotype (No, 388), female, from Ross, Calif., in collection 

 of the California Academy of Sciences. 



Paratypes in both, collections and in that of Mr. L. R. 

 Reynolds. 



4. Trichopepla grossa, new species 



Aspect of a Corpocoris but with the longer and more atten- 

 uated odoriferous canal of Trichopepla. More uniform in 

 color than our other species of Trichopepla, the radiating vittae 

 conspicuous only on head and anterior field of pronotum. 

 Length 9 to 10 mm. 



Head nearly vertical, as long as its width across the eyes, narrowing 

 anterior to the ante-ocular sinus; cheeks slightly surpassing the tylus. 

 Second antennal segment longer than third. Rostrum attaining the inter- 

 m;ediate coxse. Carinate sides of pronotum calloused but scarcely reflexed, 

 continuing the slope of the pronotal surface. Male genital segment feebly, 

 trisinuately excavated at apex. Claspers broad, truncate, their ventral 

 angle produced outwardly in a sharp bent tooth. Membrane fuliginous. 

 Upper surface regularly deeply punctured. 



Color yellowish testaceous, fusco-punctate, the punctures concolor- 

 ous beneath and on apex of scutellum. Fuscous ray-like vittae dis- 

 tinct anteriorly, fading out toward middle of pronotum. Antennae black 

 with the first and base of second segment pale. Legs pale or obscurely 

 punctate. Connexivum black, broadly margined with pale. One male is 

 almost entirely black with the apex of the scutellum and the connexivum 

 pale, the legs strongly punctured with black and the pleurae with lateral 

 vittae of black punctures. 



Described from two males and two females. One black 

 male from Julietta, Idaho, and two females from Moscow and 

 Market Lake, Idaho, were received from Prof. J. M. Aldrich. 

 The other male was taken at Castella, Calif., by Mr. J. A. 

 Kusche, July, 1912. 



Holotype (No. 389), male, from Castella, Calif, in collec- 

 tion of the California Academy of Sciences. 



Allotype, female, from Moscow, Idaho, and paratypes in 

 collection of the author.
