538 SEEEICORNIA. 



sternum with coarse punctures ; prosternal process acuminate, margined to the tip. Posterior coxal 

 plates feebly dilated in their inner third. 

 Length 3|-4f , breadth 1-1£ millim. (<??.) 



Hab. Mexico, Cordova (SallS), Jalapa (Edge) ; Guatemala, Purula, Senahu, Chiacam, 

 and San Juan in Vera Paz, Capetillo [Champion). 



Found in plenty at Jalapa, more sparingly elsewhere. This insect is a close ally of 

 G. quadraticollis, but may be known from it by the shorter, less parallel, more finely 

 punctured thorax, the inferior marginal carina of which is almost obliterated behind in 

 some specimens, the more attenuate elytra, with more distinctly angulate epipleurse, 

 and the smoother propleurse. The elytra vary in colour from piceous to almost 

 entirely testaceous ; in some examples from Purula and elsewhere they are testaceous, 

 with a well-defined black sutural stripe which is dilated at the base into a triangular 

 patch. The specimens from Capetillo have the thorax more closely punctured than 

 the others. 



4. Grlyphonyx Cimeatus. (Tab. XXIII. fig. 23, underside of prothorax.) 



Kather short, narrow, subfusiform, sbining ; varying in colour from piceous to rufo-testaceous, the head, 

 prothorax (the hind angles excepted), and suture of the elytra usually infuscate or piceous in light- 

 coloured specimens, the antennae and legs testaceous ; thickly clotbed with yellowish-cinereous pubescence. 

 Head thickly punctured ; the reflexed margins of the front meeting at an obtuse angle in the centre ; 

 antenna? extending to far beyond the hind angles of the prothorax in the male, shorter in the female, 

 joints 2 and 3 subequal in length. Prothorax transversely subquadrate, as broad a little below the apex 

 as at the base, the sides rounded in front and parallel or very feebly sinuate behind ; the hind angles 

 acutely produced, not divergent ; the lateral carina extending almost to the apex, the inferior marginal 

 carina widely separated from it anteriorly and sinuate behind ; the surface finely and rather closely 

 punctate ; the basal plicae distinct. Elytra about two and three-fourths longer than the prothorax, and 

 not wider than it, rapidly narrowing from a little below the base, somewhat pointed at the apex ; 

 punctate-striate, the interstices feebly convex at the sides, flat on the disc, and rugulosely punctured. 

 Prosternum and propleurae with scattered fine punctures ; metasternum and abdomen closely, finely 

 punctate, the sides of the metasternum with coarse punctures ; prosternal process acuminate, margined 

 to the tip. Posterior coxal plates moderately dilated in their inner third. 



Length 3|-4|, breadth 1-1 ^ millim. ( $ $ .) 



Eab. Mexico, Atoyac in Vera Cruz (E. E. Smith), Motzorongo in Vera Cruz (Flohr), 

 Teapa in Tabasco (E. E. Smith, Edge), Tapachula in Chiapas (Edge) ; British Hon- 

 duras (coll. Janson), R. Hondo (Blancaneaux) ; Guatemala, Chacoj in Vera Paz, 

 Zapote (Champion). 



Found in plenty at Teapa, Rio Hondo, and Zapote. This insect is of about the 

 same size as G. parallelus, but differs from that species in its squarer thorax, more 

 attenuate elytra, and longer antenna?, and also in the form of the prosternal process. 

 The colour is very variable, but it is usually much paler than in G. parallelus ; some 

 specimens are uniformly rufo-testaceous, and others have a well-defined dark sutural 

 stripe.
