rhomboidal and elongate, more than three-fourths as wide as the 

 prothorax, the eyes well developed and rather prominent; front 

 convex, very smooth, the anterior impressions short and shallow; 

 antennae very long and slender, nearly three-fourths as long as the 

 body, the third joint a third longer than the fourth; prothorax fully 

 as long as wide, widest just before the middle, where the sides are 

 rounded, thence feebly converging and less arcuate to the broadly 

 rounded apical angles and feebly converging, becoming straight, to 

 the basal angles, which are very obtuse though with the angulation 

 distinct; base transverse, arcuate at each side, barely as wide as 

 the feebly sinuate apex; sides broadly, deeply and equally reflexed 

 and sparsely punctulate throughout; surface with fine and feeble 

 transverse rugulae, the foveae large, concave and rather closely 

 punctate or subrugulose; anterior impression fine but evident, the 

 posterior subobsolete, the stria fine, deep and subentire; elytra 

 three-fourths longer than wide, much more than twice as wide as 

 the prothorax and between three and four times as long, the sides 

 moderately reflexed, distinctly more rounded at the humeri, the 

 apices becoming oblique and very feebly sinuate; stri« rather fine 

 but sharply defined, smooth, the intervals very indefinitely rugoso- 

 punctulate; scutellar stria long; first three anterior tarsal joints 

 feebly dilated, parallel and equal in width in the male. Length 

 (cf) 10.9 mm.; width 3.5 mm. Mexico (Cuernavaca). Source

There is nothing figured m the " Biclogia " at all resembling this 

 species and I fail to find it in the subsequent papers of Mr. Bates; 

 it is in no way allied to Colpodes, even in the broadest sense of the 

 latter, as the small fourth tarsal joint is not deeply emarginate 

 and is without suggestion of asymmetry. The tarsi have no 

 suspicion of the dorsal groove of Glyptolenus Bates. For the latter 

 reason it cannot be allied to Platyniis euprepes Bates, where the 

 tarsi are grooved above. 



Anacolpodes n. gen. 

 A very peculiar neotropical type in regard to facies, due to the 

 parallel and subrectilinear sides of the prothorax and deficiency in 

 cephalic and pronotal seta^, and represented at present by only 

 two species, justifies I think the formation of a distinct genus. 

 The type may be described as follows: 



Form ventricose, the anterior parts much narrower than the hind body, 

 the elytra rather convex; upper surface very shining throughout, 

 black, the legs and abdomen dark rufous; head rather more than 

 three-fourths as wide as the prothorax, somewhat elongate and 

 subrhomboid, the neck unusually wide, being more than two-thirds
