50 HELOTA THORACICA. 



the eyes they are smaller and placed very close together, 

 on the front portion they are smallest ; underneath the 

 brassy middle portion shows a few deeply impressed punctures. 



Prothorax widest at the base, narrowing towards the 

 front margin in regularly curved lines ; the lateral margins 

 distinctly crenulate ; the front angles produced and rounded ; 

 the base deeply bisinuate , the lateral angles acute , the 

 middle lobe rounded and with a small impression ; the disk 

 strongly and regularly closely punctured, with the usual 

 raised impunctate patches , viz. a mesial forked one , ex- 

 tending from the base on to the front margin , an elongate 

 slightly oblique basal one on each side of the former . and 

 an ovate one in front of the oblique basal patches. The 

 scutellum is small, transverse, and slightly impressed along 

 the middle. The sterna have a few punctures at the sides. 



Elytra nearly parallel, rounded posteriorly, slightly de- 

 hiscent at the suture ; each elytron with ten regular , 

 punctured striae of which the 4th and 5th are interrupted 

 by the yellow spots and are not continued behind the 

 posterior pair; the punctures of the 3rd and following 

 striae are distinctly larger and deeper than those of the 

 1st and 2nd, those of the 5th and 6th striae are trans- 

 verse; the interstices between the 5th and 10th striae are 

 very narrow and costiform , and alternately more strongly 

 raised and extending farther backward; the interstice be- 

 tween the 2nd and 3rd striae becomes costiform towards 

 the end, and extends down to the apical margin of the 

 elytra; the epipleurae are impunctate. 



Abdomen smooth , with a few minute , hair-bearing punc- 

 tures along the middle ; the last ventral segment subtruncate 

 at the apex, the truncation faintly bisinuate. 



The legs are smooth and impunctate, the anterior tibiae 

 slightly curved.
