 appearance. 



Range. Ceylon.

Phcelota semifasciata, Jac, Proc. Zool. Soc. Lond. 1887, p. 94. 



Body ovate, convex, narrowed behind. Colour shining reddish- 

 brown, with a bronzy -blackish longitudinal stripe on each elytron ; 

 towards the base of the elytra this latter colour is usually exten- 

 sively suffused and not strictly defined ; the stripe lies along the 

 outer part of the elytron, extending up to the apex, and is also 

 ill-defined as to its boundaries ; the six apical segments of the 

 antenna? are black ; surface of pronotum with obscure diffused 

 dark patches. 



Head broad, vertex convex, rather sparsely and minutely 

 punctate, and delimited from the rest of the face, which is im- 

 punctate, by a deep transverse and irregular impression ; eyes 

 large; frontal tubercles more or less prominent. Antennse about 

 two millimetres shorter than the length of the body ; first seg- 

 ment long and club-shaped, second small, slightly thicker and 

 shorter than third, the latter and the fourth slender and almost 

 equal, fifth thicker ; from the sixth onwards the segments are 

 thicker and opaque. Prothorax broader than long, convex, sides 

 straight, slightly rounded in front, anterior and posterior margins 

 almost straight ; anterior angles thickened and slightly expanded, 

 each with a seta-bearing pore ; each of the posterior angles also 

 has a seta-bearing pore, but is not so expanded as the anterior 

 angles ; surface rather sparsely and finely punctate. Scutellum 

 broad, triangular, with apex broadly rounded and surface smooth 

 and impunctate. Elytra almost as broad at base as prothorax, 

 punctate-striate ; on each elytron there are eleven rows of 

 punctures including a short scutellar and an extreme marginal 

 row ; interstices smooth, fiat and impunctate, that between the 

 ninth and the extreme marginal rows is the broadest ; the extreme 

 marginal row is situated in a deeply impressed line. Underside 

 smooth, impunctate, shining, glabrous. 



Length, 5^ mm. ; breadth, 3 mm. ; length of antenna, 3^ mm.
