130 GEO. II. HORN, M. D. 



legs are more densely pubescent. The anterior femora are armed near 

 the middle with a tooth more acute in the male than female. 



I have in my possession also a specimen considered as being vertica- 

 Us Chaud., from the description and the locality from whence it was de- 

 rived. Excepting in color tesfaceiis^ appears to differ very slightly from 

 either this or Gyllenlialu. As compared with verticalis the head is 

 more elongate and less punctured, the thorax rather less convex and 

 the median impressed line rather more evident, the hind angles are 

 also less acute. The elytra are more nearly parallel and much less 

 shining. 



This species is rare, a very small series was captured by myself 

 at Fort Grant. Arizona. 



Panag.eus Sallei Chaud., must now be considered an inhabitant 

 of our territories, numerous specimens of this and our eastern fancla- 

 tus Say were collected by me in the region with the Pachjteles above 

 described. 



TETRAGON ODERUS Dej. 

 T. pallidus, testaceous^subopaque. Head and thorax very finely granulate. 

 Thorax trapezoidal, broader than long, narrower behind, feebly emarginate at 

 apex, truncate at base ; sides rounded in front, straight and gradually conver- 

 gent behind, hind angles obtuse. Elytra faintly striate, interstices fiat, very 

 finely alutaceous. Beneath smooth, impunctured. Length .22 inch. 

 From Soutliern California (Temescal) and Arizona (rare). 

 Differs from our other species in color, and almost total absence of 

 any marked sculpture. The form of thorax is similar to fasciatus. 



ANISODACTYLUS Dej. 

 Dichirus Mann. 

 A. strenuus. oblong, moderately convex, dark brown, clothed with erect, short, 

 yellowish hairs. Head coarsely punctured. Thorax very sparsely punctured, 

 convex, shining, slightly wider than long, narrower behind, sides broadly 

 rounded, gradually narrowing, anterior angles rounded, apex feebly emarginate 

 base truncate, angles obtuse. Elytra striate, strise not punctured, interstices 

 moderately convex irregularly biseriately punctulate. Femora strongly dila- 

 ted, the anterior very robust. Length .60 inch. 



Two specimens from Fort Tejon, California. 



This is much larger and mere rcbList thin any of our species yet 

 described. As compared with hi.rsutm, it is more convex and robust, 

 with the thorax less densely punctured, less narrowed behind and less 

 emarginate in front. The thighs are also very robust, those of the au- 

 erior pair especially so.
