scription of the Mexican brcvicolUs, which has also the internal mar- 

 ginal carina obliterated behind, but the prothorax is not " consider- 

 ably broader than long " in the Arizona specimen. 



Glyphonyx ferruginosus new species. 



Elongate, ferruginosus, antennae and legs paler. Head moderately closely 

 punctate ; antennae reaching to about the hind angles of prothorax. Prothorax 

 subquadrate ; sides parallel, near apex slightly arcuate, hind angles feebly di- 

 vergent ; lateral carina not extending to the middle, inferior marginal carina 

 entire and slightly sinuate near base ; surface with moderate, well separated 

 punctures. Elytra not quite three times as long as prothorax ; striae with 

 coarse punctures at base, finer towards apex ; intervals feebly elevated and 

 finely and sparsely punctured. Prosternum and propleurae with well separated 

 moderate punctures ; prosternal process Y-shaped, metasternum more coarsely 

 punctate at sides than prosternum, abdomen rather finely punctate. Length 

 4.75 mm. 



Huachuca Mts., Arizona (Schaeffer). 



This species resembles closely tcstacciis, but has a differently 

 formed prosternal process, which is in that species V-shaped. It 

 seems to agree also with the description of the Mexican prcccox but 

 the punctuation of the prothorax in the Arizona specimens cannot be 

 called sparse and fine, the lateral carina does not extend quite to the 

 middle, and the inferior carina is scarcely sinuate behind. All our 

 species have a V-shaped prosternal process with the exception of in- 

 quinatiis, if I have correctly identified that species, and ferruginosus, 

 which have a Y-shaped prostgrnal process. 



Plastocerus granti new species. 



Elongate, very narrow ; sparsely pubescent ; dark castaneous, underside 

 paler, legs, antennae and palpi testaceous. Head very coarsely and densely 

 punctate ; eyes moderately prominent, width, as seen from the front, less than 

 one half the interocular space ; antennae with third and fourth joints equal 

 in size, fourth and following joints each with a moderately long ranius, the 

 rami not as long as the interocular spase. Prothorax subquadrate, lateral 

 margin acute, arcuate at about apical third and then feebly converging 

 towards basal angles, which are rather strongly divergent and not carinate ; 

 surface coarsely and densely punctate, the punctures acellate and more 

 crowded at sides than on the disk. Elytra a little wider than the prothorax in 

 its widest part, sides feebly converging towards apex; surface punctate- 

 striate, punctures moderate ; intervals flat and rather sparsely punctate. 

 Prosternum at about middle obliquely elevated into a moderately strong
