Dec, 1916.] New Species of Elaterid^. 265 



Enterprise, Fla. (O. Dietz). 



The long, nearly entire lateral carina and the rather feebly angu- 

 lated anterior margin of head will principally distinguish this species 

 from its nearest allies. 



Glyphonyx quadraticoUis Champion. Biol. Cent. Am. Col., Ill, i, 536. 



A species which I have taken commonly in the Huachuca Mts., 

 Ariz., agrees very well with the description of this Mexican species, 

 which is said to be also common and widely distributed in Mexico. 



The color is piceous or reddish brown. Head coarsely and closely punc- 

 tate. Prothorax subquadrate with sides parallel ; lateral carina extending 

 nearly to apex, the inferior marginal carina distinct and sinuate behind, sur- 

 face coarsely and rather closely punctate. Elytra punctate-striate, strize 

 coarsely punctured ; intervals feebly convex, somewhat rugosely punctate. 

 Presternum and propleurae with somewhat coarse, not closely placed punc- 

 tures, prosternal process acuminate. Length about 6 mm. 



Huachuca Mts., Ariz. (Schaeffer). 



The above described bimargmatus, which has also a long, nearly 

 entire, lateral carina, differs from pale colored specimens of this 

 species in having a longer and less coarsely punctured prothorax and 

 a more finely punctate prosternum and elytral intervals. 



Glyphonyx dubius new species. 



Elongate, piceous, antennae and legs paler. Head moderately coarsely, 

 not closely, punctate; antennae reaching slightly a little beyond the basal 

 angles of prothorax, second and third joints subequal. Prothorax subquadrate; 

 sides nearly parallel ; hind angles feebly divergent, lateral carina long, nearly 

 reaching to the apical margin ; inferior marginal carina entirely obliterated 

 behind ; surface sparsely and rather finely punctate behind middle of disk, 

 more coarsely and closely punctate at sides and apex. Elytra nearly two and 

 one half times as long as prothorax at base ; striae punctate with moderately 

 large punctures ; intervals feebly convex, rather sparsely and finely and not 

 rugosely punctate. Prosternum and propleurae rather sparsely punctate ; pro- 

 sternal process acuminate V-shaped ; metasternum at sides more closely punc- 

 tate than prosternum ; abdomen finely punctate at middle, more coarsely at 

 sides. Length 6 mm. 



Huachuca Mts., Arizona (Schaeffer). 



This species looks very much like quadraticoUis, mentioned above, 

 but has a more finely punctate prothorax and elytra and the inferior 

 marginal carina obliterated behind. It seems to agree with the de-
