546 SEREICOENIi. 



One specimen. Easily separable from our other species by the four-spotted elytra. 

 The post-humeral spot resembles an oblique, inverted V- G. quadrinotatus is nearest 

 allied to G.fasciatus, but easily separable therefrom by the non-divergent hind angles 

 of the thorax. 



18. Glyphonyx fasciatus. 



Moderately elongate, very narrow, shining ; black, the elytra testaceous, with the suture and a broad, trans- 

 verse, indeterminate, ante-median fascia fuscous, the antennae pitchy-brown, with the two basal joints 

 testaceous, the legs testaceous; thickly clothed with yellowish-cinereous pubescence. Head sparsely, 

 finely punctate ; the reflexed margins of the front meeting at an obtuse angle in the centre ; antennae 

 extending to far beyond the hind angles of the prothorax, joint 3 much shorter than 2. Prothorax 

 transverse, the sides gradually and arcuately converging from the middle forwards and feebly sinuate 

 behind; the hind angles very long, slender, and strongly divergent, slightly incurved at the tip; the 

 lateral carina about reaching the middle, the inferior marginal carina widely separated from it anteriorly, 

 and sinuate behind : the surface finely and rather sparsely punctate ; the basal plicae very indistinct. 

 Elytra three and one-half times longer than the prothorax, and much wider than it, rounded at the sides, 

 narrowing from the middle, pointed behind ; deeply and coarsely punctate-striate, the interstices convex 

 and sparsely punctured. Prosternum and propleurae with widely scattered tine punctures ; metasternum 

 and abdomen finely and rather closely punctate; prosternal process Y-shaped, the triangular intercoxal 

 portion margined. Posterior coxal plates feebly dilated in their inner third. 



Length 3, breadth T 9 ¥ millim. 



Hab. Guatemala, Purula in Vera Paz (Champion). 



One specimen only, no doubt a male, of this peculiar little species has been obtained. 

 It is not very closely allied to any of the others here described. From G. angulatus it 

 may be separated by the relatively narrower thorax, the more oval elytra, the differently- 

 formed prosternal process, &c. ; and from G. cruciellus by the much narrower thorax, 

 with strongly divergent hind angles, the more oval elytra, &e. 



19. Glyphonyx cinctus. (Tab. XXIII. fig. 32.) 



Moderately elongate, rather robust, shining ; rufo-testaceous or testaceous, the elytra with the suture and a 

 broad transverse median faseia — in some specimens extending to the outer margin, and in others reduced 

 to a common rhomboidal mark — black or piceous, the sutural stripe sometimes dilated into a triangular 

 patch at the base ; thickly clothed with yellowish-cinereous pubescence. Head closely, finely punctate ; 

 the reflexed margins of the front meeting at an obtuse angle in the centre; antennae about reaching the 

 hind angles of the prothorax in the female, a little longer in the male, joints 2 and 3 subequal in length. 

 Prothorax broader than long, the sides rounded in front and almost parallel behind ; the hind angles 

 acutely produced, not divergent; the lateral carina extending forwards to about the middle, the inferior 

 marginal carina beeoming widely separated from it anteriorly and sinuate behind ; the surface somewhat 

 closely, finely punctate; the basal plicae well defined. Elytra two and two-thirds longer than the 

 prothorax, and of the same width, gradually narrowing from the basal third, obtuse behind ; deeply 

 punctate-striate, the interstices almost flat and rugulosely punctured ; epipleurae angulate opposite the 

 hind coxae. Prosternum and propleurae sparsely punctate, the punctures on the propleurae coarse ; 

 metasternum and abdomen closely, finely punctate, the punctures on the sides of the metasternum 

 coarser ; prosternal process Y-shaped, margined to beyond the coxae. Posterior coxal plates feebly dilated 

 in their inner third. 



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



Hab. Mexico, Soledad in Vera Cruz (Salle), Teapa in Tabasco (coll. Janson) ; 

 British Honduras, Belize (Blancaneaux).
