IT 2 DESCRIPTIONS OP NEW SPECIES. 



medium albo-pubescente, apice trnncatis, et 3 vel 4-denticulatis ; pedibu? 

 piceis, anteunis flavo-testaceis. Long. 4-5 mm. 



Lower California, Mr. Ulke. A singular species, but resem- 

 bling entirely in form and size G. minuta. The elytra are dis- 

 tinctly truncate at tip, and the truncature is serrate, the suture 

 and outer angle being prominent, with one or two intermediate 

 cusps. 



CALLIDIOI FABR. 



485. C. vile. Nigrum, subtiliter ciiiereo-pubescens, prothorace latitu- 

 dine vix breviore, lateribus rotundatis, fortiter punctate ; elytris sat 

 dense fortiter punctatis, et transversim rugosis ; antennaruin articulo 

 2do sequeute triplo breviore. Long. 4-5 mm. 



Mendocino, California; collected by Mr. Behrens. Readily 

 known by the small size, black color, and coarse sculpture. The 

 thighs are strongly clubbed, the front coxae are contiguous, and 

 the mesosternum obtusely triangular. I cannot see the meso- 

 notum, but I have no doubt from the other characters that there 

 is no stridulating surface. 



486. C. hirtellum. Elongatum minus depressum, nigrum nitidum, 

 pubescens, et pilis nigris erectis villosum, prothorace ferrugineo, punc- 

 tato, callis laevibus baud elevatis ornato, latitudine paulo breviore, 

 lateribus rotundatis ; elytris concinne punctatis ssepe testaceis ; anteunis 

 pilosis, basi rufescentibus, articulo 2do 3io dimidio breviore. Long. 

 8 mm. 



Nevada, Mr. Ulke. . Two specimens, one of which is black, 

 with the prothorax ferruginous ; the other has also the elytra 

 brownish ferruginous. The mesonotum is smooth and polished, 

 with a few scattered punctures; the mesosternum is triangular ; 

 the thighs strongly clubbed, the front coxae contiguous. C. 

 sereum Newman (pallipes Hald.}, belongs to the same division 

 of the genus, characterized by the rather stout antennae, not 

 thickened but very hairy towards the base, with the 2d joint about 

 half as long as the 3d, and the punctuation less dense than in the 

 metallic blue species. 



XYLOCRIITS LEC. 



487. X. critoratus. Ater, pube uigra villosus, prothorace fortiter 

 punctate, latitudine breviore, postice subangustato; lateribus antice 

 valde rotundatis, postice subsinuatis ; elytris subreticulatim grosse 

 punctatis, punctis versum apicem paulo miuoribus. Long. 12-5 mm.
