new Coleoptera from Madagascar. 501 



Eutrichesis pilosicollis, n. s. 

 Elongatus, parallelus, castaneus, subtus testaceus ; 

 capite fusco, confertim fortiter punctate, thorace con- 

 vexo, fusco-castaneo, confertim ruguloso-punctato et sub- 

 tiliter flavo-piloso pilis longis intermixtis, antice per- 

 parum angustato, lateribus arcuatis crenulatis, elytris 

 parallelis crebre fortiter punctatis, pallide pilosis. Long. 

 14 lin., lat. 7 lin. 



This species is close to the preceding, but differs in 

 having the thorax relatively a little broader, and un- 

 usually little narrowed anteriorly. The clypeus is less 

 emarginate. The punctuation of the thorax is finer and 

 more even, and there is no smooth median line ; the 

 pubescence is liner and closer. The pygidium is more 

 triangular in outline and less rugosely punctured. The 

 punctures on the middle portion of the abdomen are 

 finer, and the basal segment is finely and rather thickly 

 punctured all over.

Eutrichesis placidus, n. s. 



Brunneus, subtus testaceus, crebre punctatus, pallide 

 pilosus; capite infuscato, thorace crebre fortiter punc- 

 tato, elytris postice paulo amplioribus, abdomine crebre 

 punctato. Long. 14| lin., lat. T^ lin. 



This species differs from the foregoing in being less 

 parallel in form, the thorax being more narrowed in 

 front, and the elytra more enlarged posteriorly. The 

 clypeus is formed as in E. pilosicollis, but the head 

 is rather more confusedly punctured. The punctuation 

 of the thorax is rather strong, but, although the punc- 

 tures are very close together, they are distinct from each 

 other, and not confused as they are in both the preceding 

 species. The scutellum is more finely and more sparingly 

 punctured. The elytra are relatively shorter ; the sculp- 

 ture is very similar. The pygidium is rather more semi- 

 circular in outline than in E. pilosicollis. The abdomen 

 is rather thickly and comparatively finely punctured, 

 very closely so at the sides ; the middle of the second 

 segment and middle of the third segment (the margin 

 excepted) sparingly punctured ; the pubescence very fine. 



Hah. Antananarivo (Kingdon).
