cies have been described from America, including one from the 

 Guadeloupe Islands. The American species are not entirely con- 

 generic with the species from Malaysia and probably should form 

 a new genus, but until more material is available for study it is ad- 

 visable to retain them in the present genus. 



TRACHYS GUADELOUPENSIS (Fleutiaux and Salle) 



Lius gtiadeloupeiisis Fleutiaux and Sai.le, Ann. Soc. Ent. France, ser. 6, 



vol. 9, 1890, pp. 404-405 (separates pp. 54-55). 

 Trachi/s chevrolati KERUE^rAxs, Ann. Soc. Ent. France, vol. 65, 1896, pp. 

 26-27. 



Elongate, moderately convex, broadly rounded in front, attenuate 

 posteriorly, and slightly narrower behind than in front, glabrous and 

 strongly shining, uniformly aeneous above; beneath piceous, with a 

 slightly aeneous tinge. 



Head broad, nearly flat, feebly longitudinally impressed on the 

 front, deeply transversely impressed behind the epistoma, with a 

 round deeper impression behind the antennal cavities; surface 

 sparsely and irregularly punctate, the punctures shallow and rather 

 coarse on the occiput, but becoming nearly obsolete toward the 

 epistoma; intervals smooth; epistoma wide between the antennal 

 cavities (about three times as wide as the cavities), the anterior mar- 

 gin deeply, arcuately emarginate and strongly elevated; antennae 

 rather short and entirely piceous. Pronotum slightly convex, two 

 and one-half times as wide as long at middle, distinctly narrower 

 in front than behind, and widest at base; sides obliquely arcuate 

 from base to anterior angles and narrowly margined ; anterior an- 

 gles acute; posterior angles nearly rectangular and slightly project- 

 ing; anterior margin broadly arcuately emarginate, with an obsolete 

 lobe at middle ; base transversely truncate to near middle of el^ytron, 

 then feebly sinuate and turning obliquely backward to the scutellum, 

 in front of which it is broadly rounded ; surface narrowly impressed 

 along lateral margin, and with a broad, shallow impression near the 

 posterior angles; punctuation similar to that on the head. Scutel- 

 lum very small and triangular. Elytra moderately convex, dis- 

 tinctly wider than pronotum at base; humeral angles broadly 

 rounded ; sides feebly obliquely attenuate to behind the middle, then 

 arcuately attenuate to the tips, which are conjointly narrowly 

 rounded, with the lateral margin entire ; each elytron with a broad, 

 shallow impression at base, and a more elongate one behind the 

 humerus close to the lateral margin, causing an obsolete elevation 

 near the middle at lateral margin, which is less elevated than the 

 humerus; surface without lateral carina, rather densely and irregu- 

 larly punctate, the punctures coarse and stelliform at base, becom- 

 ing more obsolete at the apex; intervals smooth. Abdomen beneath
