GLYPHONYX. 539 



5. Gly phony x rugipennis. 



Moderately elongate, convex, narrow, shining ; black, the elytra in one example obscure reddish-brown with, 

 the suture broadly infuscate, the antennae and legs testaceous ; thickly clothed with rather long, fine, 

 yellowish-cinereous pubescence, which is semierect on the upper surface and decumbent beneath. Head 

 closely punctured ; front triangular, the margins strongly reflexed and meeting at an obtuse angle in the 

 centre ; antennse nearly half the length of the bodv in the male, shorter in the female, joints 2 and 3 

 subequal in length. Prothorax nearly as long as broad, subquadrate in the male, less parallel in the 

 female, the sides rounded at the apex and feebly sinuate behind ; the hind angles acutely produced, 

 slightly divergent ; the lateral carina short and very fine, extending to very little beyond the basal third, 

 the inferior marginal carina widely diverging from it and faint or obliterated in the middle ; the surface 

 closely, rather finely punctate, with a narrow space down the middle impunctate ; the basal plica? very 

 fine. Elytra about two and three-fourths longer than the prothorax, and slightly wider than it, narrowing 

 from the basal third, and somewhat obtuse behind ; punetate-striate, the interstices flat and densely, 

 rugosely punctured, becoming smoother beyond the middle and granulate towards the base. Prosternum 

 and propleuroe sparsely punctured ; metasternum and abdomen closely and rather finely punctate ; 

 prosternal process sharply acuminate, margined to the tip. Posterior coxal plates moderately dilated in 

 their inner third. 



Length 4|-5|, breadth lf-1^ millim. ( c? ? .) 



Hab. Guatemala, Zapote {Champion). 



Five specimens. This insect is of about the same size and shape as G. quadraticollis, 

 but may be known from it, and all our other species of the genus, by the rugose 

 elytral interstices. The inferior marginal carina of the thorax is obliterated in the 

 middle in all but one of the specimens obtained, it being also much less distinct than 

 in G. quadraticollis. The thorax, except for a narrow space along the middle, is 

 closely punctured throughout. The pubescence on the upper surface appears to be 

 more erect than usual. G. fusculus, Cand., from Cuba, is an allied form. 



6. G-lyphonyx vittatus. 



Moderately elongate, narrow, shining ; black, the elytra broadly testaceous at the sides (leaving a broad black 

 or piceous attenuate sutural stripe), the margins usually infuscate or piceous, the antennse brown, with 

 the two basal joints testaceous, the legs testaceous, the under surface sometimes reddish-brown ; thickly 

 clothed with yellowish-cinereous pubescence. Head thickly punctured ; the reflexed margins of the front 

 meeting at an obtuse angle in the centre ; antenna) extending to considerably beyond the hind angles of 

 the prothorax in the male, shorter in the female, joint 3 shorter than 2. Prothorax much broader than 

 long, the sides rounded in front and feebly sinuate behind ; the hind angles acutely produced, feebly 

 divergent; the lateral carina short, not reaching the middle, the inferior marginal carina widely 

 diverging from it and strongly sinuate behind ; the surface thickly, finely punctate ; the basal plicae very 

 fine. Elytra three times the length of the prothorax, and scarcely wider than it, gradually narrowing 

 from the basal third, and somewhat pointed behind ; punetate-striate, the interstices rather convex and 

 finely punctured. Prosternum and propleuree sparsely punctured, the punctures on the propleurae coarse ; 

 metasternum and abdomen thickly, finely punctate, the sides of the metasternum with coarser punctures ; 

 prosternal process acuminate, margined to near the tip. Posterior coxal plates moderately dilated in 

 inner third. 



Length 3J-41, breadth 1-1^ millim. ( d $ •) 



Hab. Mexico, Omilteme, Xucumanatlan, Chilpancingo, and Amula in Guerrero 

 (II. II. Smith). 



Seven specimens. In the broad black well-defined sutural stripe of the elytra this
