272 Mr. F. Bates' Descriptions of 



zoilus, Hyjjocilihe and Onosterrhiis, the intercoxal process 

 is broad, parallel-sided, the apex broadly rounded or sub- 

 truncated ; and the epimera are more or less posterior, 

 allowing the episterna to more or less widely attain the 

 sides of the mesothorax. 



*S'. Duboulayi, n. sp. 



$ Long. 8 lin. ; elytra lat. 4^ lin. — Oblong, subparallel ; 

 dull-black with a slight chocolate tinge, the foliaceous 

 margins of the prothorax chocolate-brown : head and pro- 

 thorax rugosely-tuberculate, the tubercles flattened and 

 more or less run together and shining on the disc of the 

 latter, the sides simply tuberculate, the foliaceous margins 

 reticulately rugose, the edges crenulate : elytra elongate- 

 oval, sides subparallel, distinctly margined in the basal 

 half, less so in the apical half, these margins transversely 

 rugose ; an oblong depression behind the scutellum ; each 

 with 4 strongly elevated, shining, more or less tuberculi- 

 form costas, these — save the 2 inner dorsal ones at their 

 basal half — are represented by irregular, (both as to form 

 and size) more or less strongly detached tubercles, the 

 subapical ones being largest and umbilicated ; there is 

 also a line of more or less elongate, slightly elevated 

 tubercles closely bordering each side the suture which 

 become bifurcate at the scutellar depression : the inter- 

 vals are narrow, slightly and irregularly rugose, indis- 

 tinctly punctate, and studded with variously-sized small 

 tubercles round or conical and shining : beneatli, the 

 mentum, sterna and flanks of meso- and metasterna are 

 more or less coarsely rugose and punctured, flanks of the 

 prothorax tubercidate : the epipleural fold, save at the 

 base, is ruggedly rugose ; abdomen finely and not closely 

 punctured ; legs pubescent, femora punctured but not 

 closely, tibiffi closely, finely (except the anterior) reticu- 

 lately rugose-punctate. 



? ? Long. 9 lin. ; elytra lat. 5f lin. — Oblong-oval, 

 robust ; of a similar colour to the $ but duller, the tubercles 

 &c. considerably less nitid : the disc of the prothorax is 

 less strongly tubercled, and these are less run together 

 than in the $ , the foliaceous margins are more strongly 

 rugose and with scattered small tubercles : elytra ample, 

 briefly oval, depressed, much wider than the prothorax at 

 its widest part ; the costa3 are not so elevated as in the $ , 

 the 2 inner dorsal ones subcontinuous to near the apex.
