tlie edi;;e, but it is continued behind the head somewhat away 

 from the edge ; round the anterior angles there is also a 

 marginal stria ; the elytra, the oblique humeral stria is fine 

 but clearly marked, the other humeral striai are wanting, 

 dorsal strite 1-3 complete, the second at the base for one third 

 of its length turns inward towards the third, 4—5 are apical 

 and rudimentary ; the propygidium is transversely punctured ; 

 the pygidium wholly and more densely punctured ; the punc- 

 tures on both appear under the microscope to be obscurely 

 ocellate, outer margin of the pygidium is slightly raised ; the 

 prosternum is without strife ; the mesosternum is marginate 

 and feebly sinuous behind the prosternal keel ; the anterior 

 tibiee are 4-dentate. 



The form of this species is similar to P. carolinum, Payk., 

 P. sincerum, Sch., and others. It is only the second species 

 of Platysoma known with maculate elytra. 



Hah. Palembang, Sumatra. 



Cypiurus hengalensis, sp. n. 



Ovplis, ohlongus, convexus, aeneo-niger ; fronte rugoso-punctata ; 

 ehtris, striis 1-3 integris, 4-5 basi evanesoentibus, suturali 

 ut'rinqiie vix abbreviata ; prosterno stria marginali antice acumi- 

 nata. 



L. 6 miU. 



Oval, oblong, convex, brassy black, somewhat shining and 

 very similar to C. cenescens, Er., in general sculpture ; but it 

 differs distinctly in being larger, tlie head more coarsely and 

 rugosely punctate ; the eiytral striae are less clear, owing to 

 their interstices being very densely granulate-punctate (not 

 simply punctulate as in C. cenescens), the prosternal keel 

 anteriorly is acuminate (not arcuate), tlie mesosternum is 

 sometimes distinctly punctulate, and the female has two rather 

 small rugose lobe-shaped impressions close together behind 

 the middle of the disk of the pygidium, and on either side of 

 them, but nearer the apex, is a transverse rugose excavation; 

 t!io, two excavations are somewhat larger than the two im- 

 pressions. In C. cenescens $ the pygidium has a smooth 

 median carina, and on either side of it are two large and deep 

 ruo-ose impressions which occupy the whole area of the disk. 



Hah. Bengal. 



1 am indebted to Herr Hilmar v. Schonfeldt for fourteen 

 examples of this species. C. cenescens is also reported as 

 occurring in Bengal, but all the specimens in my collection 

 are from the ISilgiri Hills and Ceylon.
