HELOTA ATTENUATA. 113 



r 



Head strongly but rather remotely punctured in the 

 raised middle portion , very closely between the raised 

 portion and the eyes, very minutely on the narrowed 

 front portion. 



Prothorax transverse, strongly attenuated in regularly 

 curved sides towards the front margin , the front angles 

 but very slightly prominent, subangular, the sides faintly 

 crenulate, the base 'deeply bisinuate , the lateral angles 

 acute and slightly directed inwards, the median lobe sub- 

 truncate; the upper surface strongly but rather irregularly 

 punctured , the punctures on the middle considerably finer 

 than on the sides, an impuuctate spot in front of the 

 scutellum , and on each side of the median lobe an oblique 

 shallow impression provided with large punctures. The 

 scutellum transverse, broadly rounded behind, impunctate 

 but impressed in the middle. 



Elytra conspicuously narrowing in straight lines to- 

 wards the apices which are almost conjointly rounded. 

 Each elytron with ten regular striae of punctures which 

 become slightly larger towards the sides; the interstices 

 are sparsely and most finely punctured, and become 

 slightly costate on the apical portion , especially the 

 3rd and 9th. 



The underside of the head is strongly punctured , the 

 middle of the throat, however, impunctate; on the lateral 

 portions of the prosternum the punctures are rather large, 

 on the sides of the metasternum they are much finer ; 

 the middle of the prosternum is finely and sparsely punc- 

 tured, that of the metasternum impunctate; the abdomen 

 is apparently impunctate in the middle, distinctly punc- 

 tured, however, on the sides and on the last segment 

 which latter is truncate at the tip with rounded angles. 

 The metallic coloured tip of the femora and the 

 tibiae are distinctly punctured; the anterior tibiae slightly 

 curved. 



Two female specimens , one of which is now in the 

 collection of the Leyden Museum.
