GLYPHONYX. 547 



Six examples, those from Belize (probably all females) being considerably smaller 

 and paler than the others. Broader and more robust than G. cruciellus, the thorax a 

 little more coarsely punctured, the median fascia of the elytra better defined in the 

 well-marked specimens, the prosternal process more gradually acuminate, with the 

 smooth posterior portion shorter. The Mexican specimens are rufo-testaceous, with 

 the elytra testaceous, the dark markings being well-defined in two of them ; those from 

 Belize have a common rhomboidal dark mark on the elytra, in addition to a narrow 

 sutural stripe. A specimen from Soledad is figured.

Adrastus cruciellus, Erichs. Zeitschr. fur Ent. iii. p. 120 \ 

 Glyphonyx cruciellus, Cand. Monogr. Elat. iv. p. 456 2 . 



Moderately elongate, narrow, shining, finely pubescent ; testaceous, the disc of the prothorax and the meta- 

 sternum slightly infuscate in some specimens, the elytra sometimes with the suture, or the suture and a 

 transverse median fascia, infuscate. Head thickly, 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 pro- 

 thorax in the male, shorter in the female, joint 3 slightly shorter than 2. Prothorax strongly transverse, 

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

 divergent ; the lateral carina extending forwards to beyond the middle, the inferior marginal carina 

 gradually diverging from it and feebly sinuate behind ; the surface sparsely, finely punctate ; the basal 

 plicae fine. Elytra three times the length of the prothorax, and of the same width, narrowing from the 

 basal third, and somewhat pointed behind ; rather coarsely punctate-striate, the interstices feebly convex 

 and finely punctured ; epipleurae angulate opposite the hind coxa?. Prosternum and propleurae with 

 widely-scattered rather coarse punctures ; metasternum and abdomen somewhat thickly, finely punctate, 

 the sides of the metasternum with coarser punctures ; prosternal process Y -S baped, the triangular inter- 

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

Hab. Mextco 1 2 ; Guatemala, Panzos and Cubilguitz in Vera Paz, Zapote 

 (Champion); Panama, Volcan de Chiriqui (Champion). — Colombia 2 ; Venezuela, 

 Cumana (coll. Janson, ex Laferte). 



Smaller, narrower, and less robust than G. cinctus ; the thorax smoother, and with 

 the inferior marginal carina more gradually divergent from the lateral one; the 

 prosternal process more abruptly acuminate ; the antenna? more elongate. From 

 G. prmcox it may be separated by the less divergent thoracic carina? ; the apparently 

 less acuminate front (Erichson states 1 that G. cruciellus is easily separated from 

 G. prcecox by the truncate angle of the anterior frontal margin) is an illusory character. 

 The different forms occur at Zapote, and al o in Venezuela. The Chiriqui specimens 

 are entirely testaceous. I have not seen an example from Mexico. 



21. Glyphonyx teapensis. 



Short and rather narrow, shining ; varying in colour frompiceous to clear rufo- or flavo-testaceous, the antennae 

 and legs testaceous ; thickly clothed with yellowish-cinereous pubescence. Head finely, rather sparsely 

 punctate ; the reflexed margins of the front meeting at a somewhat acute angle in the centre ; antennae 

 extending to considerably beyond the hind angles of the prothorax in the male, shorter in the female, 

 joints 2 and 3 subequal in length. Prothorax strongly transverse, the sides rounded and converging
