540 SEKEICOKNIA. 



species resembles one of the varieties of G. tenuis, from which it may be known by its 

 less elongate shape, short thorax, with more divergent carinse, and the more acuminate 

 prosternal process. The single specimen from Amula has the sutural stripe narrower 

 and paler than usual. G. vittatus is smaller than G. brevicollis, and has darker antennae, 

 a much shorter marginal carina to the thorax, coarsely punctured propleurae, &c. It is 

 more parallel than G. angulatus. 



7. Glyphonyx angulatus. (Tab. XXIII. figg. 28 ; 28 a, underside of pro- 

 thorax.) 



Somewhat fusiform, narrow, convex, shining ; black, the prothorax sometimes piceous, the anterior and hind 

 angles of the latter, the antenna and legs testaceous ; the elytra testaceous, with a sutural stripe, widening 

 anteriorly into a large triangular scutellar patch, and an oblique mark on the outer part of the disc about 

 the middle, or the sides at this part, black ; thickly clothed with yellowish-cinereous pubescence. Head 

 thickly, finely punctate; front with the reflexed margins meeting at an obtuse angle in the centre; 

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

 strongly transverse, the sides rounded anteriorly and converging and sinuous behind ; the hind angles very 

 narrowly and acutely produced, strongly divergent, and somewhat incurved at the tip; the lateral carina 

 extending forwards to the middle, the inferior marginal carina widely separated from it anteriorly, and 

 obliterated behind ; the surface finely, sparsely punctate ; the basal plicae indistinct. ^ Elytra three times 

 the length of the prothorax, and much wider than it, rapidly narrowing from the basal third, and some- 

 what pointed behind ; punctate-striate, the interstices feebly convex and sparsely punctured ; epipleurge 

 conspicuously angulate opposite the hind coxae, and hollowed for the reception of the apices of the hind 

 femora. Prosternum and propleurae with widely scattered very fine punctures, the propleurae concave and 

 smooth behind ; metasternum sparsely, the abdomen more closely, punctate, the sides of the metasternum 

 with coarser punctures ; prosternal process acuminate, margined to the tip. Posterior coxal plates slightly 

 dilated in their inner third. 



Var. The elytra with the suture only black. 



Length 3£-4, breadth 1-1 g millim. 



Hab. British Honduras, R. Sarstoon (Blancaneaux) ; Guatemala, Sinanja in Vera 

 Paz (Champion). 



Five examples of the type and one of the variety, the latter being from British 

 Honduras. This small species, in its typical form, may be readily identified by its 

 peculiar coloration, as well as by the partial obliteration of the inferior marginal carina 

 of the thorax and the conspicuously angulate elytral epipleurse. This last-mentioned 

 character, which is visible from above, gives the elytra the appearance of being gradually 

 widened in their basal third. The insect is closely allied to G. brevicollis; but it is 

 smaller and less robust, the thorax is relatively narrower and more constricted behind, 

 and the elytra usually have an oblique mark on the middle of the disc, as well as the 

 suture, black. 



8. Glyphonyx propinquus. (Tab. XXIII. fig. 24, underside of prothorax.) 



Moderately elongate, narrow, shining ; piceous or brown, the hind angles of the prothorax obscure testaceous, 

 the suture of tbe elytra sometimes very narrowly infuscate, the antennae and legs testaceous ; 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 nearly two-fifths of the length of the body in
