anteriorly and sinuate and slightly converging behind ; the hind angles acutely produced and feebly divergent; 

 the lateral carina about reaching the middle, the inferior marginal carina gradually diverging from it and 

 scarcely sinuate behind ; the surface sparsely, finely punctate ; the basal plicae very fine. Elytra three times 

 the length of the prothorax, and a little wider than it, gradually narrowing from the basal third, and 

 somewhat pointed at the apex ; finely punctate-striate, the interstices flat and finely punctured; epipleurae 

 angulate opposite the hind coxae. Prosternum and propleurae with widely scattered rather coarse punctures ; 

 metasternum (the sides included) and abdomen closely, finely punctate ; prosternal process Y-shaped, 

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

 Length 2f-3A, breadth 1 millim. ( <$ $ .) 



llab. Mexico, Teapa in Tabasco (coll. Janson, Edge, H. H. Smith). 



Sent in numbers from Teapa. Less elongate than G. cruciellus and G. prwcox, and 

 of the size of the smallest examples of those species, the elytra more finely punctate- 

 striate, and more gradually narrowed behind, especially in the females. The colour is 

 even more variable than in G. cruciellus, but there is no trace in any of the specimens 

 of a sutural stripe or median fascia on the elytra. 



22. Glyphonyx parallelus. (Tab. XXIII. fig. 27, underside of prothorax.) 



Oblong-oval, convex, narrow, shining ; black or piceous, the elytra sometimes brown or brown with the suture 

 darker, the antennae and legs testaceous ; thickly clothed with yellowish-cinereous pubescence. Head 

 closely, rather coarsely punctate ; the reflexed margins of the front meeting at an obtuse angle in the 

 centre ; antennas about reaching the hind angles of the prothorax, joint 3 slightly shorter than 2. Pro- 

 thorax a little broader than long, the sides subparallel behind and rounded in front ; the hind angles 

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

 -carina gradually diverging from it and feebly sinuate behind ; the surface thickly, somewhat coarsely 

 punctate, the punctuation becoming finer and more diffuse towards the base ; the basal plicae long and 

 well-defined. Elytra about two and three-fourths longer than the prothorax, and of the same width, 

 gradually narrowing from the basal third, rather obtuse behind ; punctate-striate, the interstices fiat and 

 rugosely punctured. Prosternum and propleurae with widely scattered fine punctures ; metasternum and 

 ■abdomen thickly, finely punctate; prosternal process Y-shaped, the triangular intercoxal portion margined. 

 Posterior coxal plates feebly dilated in their inner third. 



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



Hob. Mexico, Guanajuato [Salle), Chilpancingo in Guerrero (Hoge, H. H. Smith), 

 Amula in Guerrero (H. H. Smith). 



Sent in abundance from Chilpancingo in Western Mexico. This small species 

 chiefly differs from the numerous similarly-coloured forms in its more parallel shape, 

 the rather obtuse apices of the elytra, and the Y-shaped prosternal process ; the 

 last-mentioned character separates it from G. quadraticollis and its allies. 



23. Glyphonyx minimus. 



Eather short, oblong-oval, narrow, shining ; black or piceous, sometimes with the hind angles of the prothorax 

 testaceous and the elytra brownish, the antennae and legs testaceous, the antennae sometimes with joints 

 4-11 brownish; thickly clothed with yellowish-cinereous pubescence. Head thickly punctured; the 

 reflexed margins of the front meeting at an acute angle in the centre ; antennas extending to a little 

 beyond the hind angles of the prothorax in the male, shorter in the female, joint 3 shorter than 2. 

 Prothorax strongly transverse, the sides rounded in front and parallel or feebly sinuate behind ; the hind
