178 ASTRAEUS ELONGATUS. 



The head coarsely punctured in front, much more dis- 

 tantly on the vertex. 



The prothorax deeply and coarsely punctured , towards 

 the sides rather rugose, the fordermargin slightly produced 

 in the middle, the sides somewhat narrowed anteriorly, 

 the base very deeply bisinuate , the posterior angles acute 

 and strongly projecting. 



Elytra as broad as the thorax at the base , the sides almost 

 parallel , behind the middle narrowed towards the apices , 

 which are divergent and provided with a strong subacute 

 sutural spine and a short marginal one just above it. 

 Each elytron has nine sharp ridges on the disk, with the 

 interstices deepened , and two deep striae along the margin , 

 with the interstices subconvex ; all the interstices with 

 deep but distant punctures. 



Beneath coarsely punctured, the punctures becoming 

 more numerous and finer at the abdomen; with a few 

 scattered hairs. 



This species is very parallel and, in proportion to its 

 length , very narrow.
