132 HELOTA ROUYERI. 



the claw-joint and that of the claws themselves ; an in- 

 fuscate stripe is present along the upperside of the ante- 

 rior femora. 



Head strongly produced in front of the eyes; the raised 

 middle portion between the eyes distantly covered with 

 very large punctures, the punctuation near the eyes fine 

 and dense, that on the narrowed front portion still finer 

 and more remote; underneath the head is irregularly punctate. 



Prothorax slightly transverse, widest at the base, narrow- 

 ing in nearly straight lines to the front; the front angles 

 slightly produced ; the base bisinuate, the lateral angles 

 acute, the median lobe subtruncate and with a punctiform 

 impression; the disk provided with nearly impunctate rai- 

 sed patches arranged in the following manner: a mesial 

 forked one extending from the base on to the anterior 

 margin, a short basal one on both sides of the median 

 lobe and a large, very irregular lateral one midway between 

 the basal- and front margin; the rest of the disk is co- 

 vered with large deep punctures. Tbe sterna show laterally 

 a few rather indistinct punctures. The scutellum is trans- 

 verse and impunctate. 



Elytra slightly narrowing in nearly straight lines as far 

 as the posterior yellow spots, thence more strongly nar- 

 rowed in regularly convex lines towards the apices which 

 are bluntly pointed and narrowly dehiscent at the suture; 

 each elytron has ten regular striae of punctures of which 

 the 4tli and h^^ are interrupted by the yellow spots and 

 are not continued behind the posterior one; the punctures 

 are very minute in the middle of the l^t to 4tli, slightly 

 larger in that of the 5tli and Q^^ striae; in the 7^^ to 

 10th striae the punctures are large; the interstices between 

 the Q^^ and lOt** striae are costiform, those between the 

 6th and 7th and between the 8th and 9th striae are broad- 

 er and more strongly raised than those between the 

 7th and 8th and 9th and 10th striae; the interstice between 

 the 2nd and 3''d striae becomes costiform towards the end 

 of the elytra; the shoulders are impunctate.
