NEW PHYTOPHAGOUS COLEOPTERA. 49 



ferent forms before me which I take to represent the sexes; in 

 one of them ( J^ ?) the antennae have the joints distinctly di- 

 lated at the middle and the pale elytral patch is of an oval 

 sliape, leaving the apex and suture black or piceous; in the 

 other form the antennae are more slender the third joint espe- 

 cially being longer and the entire posterior portion of the elytra 

 is yellowish white leaving only the margins narrowly black but 

 of equal width; both these varieties were obtained at the same 

 place, Fabricius no doubt made his description from those spe- 

 cimens in which the elytral light portion was oval shaped. 



40. Selbaetlxe eelelbensis , n. sp. 



Ovate , obscure testaceous , head and thorax impunctate ; elytra 

 finely punctured, their posterior portion more or less obscure 

 fuscous. 



Length 2 Y^ - 3 lines. 



Var. elytra entirely dark testaceous. 



Head impunctate , the front tubercles distinct , oblong and se- 

 parated by a well defined longitudinal groove; another trans- 

 verse groove more or less distinctly impressed is placed between 

 the eyes; antennae more than half the length of the body, 

 entirely testaceous or dark fiavous, the third joint double the 

 length of the second, the fourth distinctly longer than the pro- 

 ceeding one; thorax narrowly transverse, three times as broad 

 as long, the sides regularly rounded and narrowly margined; 

 the anterior angles slightly produced outwards but not acute ; 

 surface entirely impunctate even when seen under a strong lens; 

 scutellum trigonate impunctate ; elytra subdepressed, a little wide- 

 ned towards the middle, narrowly margined with a short lon- 

 gitudinal depression at the middle of the base; surface finely and 

 rather closely punctured with the exception of the extreme apex, 

 of a dark testaceous or pale fulvous colour , their apical portion 

 more or less stained with fuscous; presternum distinct; anterior 

 coxal cavities open.
