No. 1-] E. P. Stebbing — Predaceous Coccinellidce, Indian Region. 53 



Beetle. — Canary to orange-yellow, long-ovate. Prothorax elliptical, 

 with a median transverse crescent-shaped black mark and a posterior 

 one on edge ending on either side in a black blotch. Elytra with a 

 black mark like a reversed C on basal two-thirds and a black spot 

 near upper anal corner. Long. 4*3 — 4/5 millim. 



Distribution. — Ganjam District, Madras Presidency (Collector of 

 Ganjam, 1888). 



Life-History. — In September 1888 the Collector of Ganjam 

 forwarded to the Museum specimens of beetles reported to destroy 

 cotton, red gram, and cucumber. The insects proved to be the chry- 

 somelid beetle, Aulacophora abdominalis and the coccinellid P. sex- 

 maculata. This latter beetle is probably predaceous upon the 

 former. 



Nothing further appears to have been reported on this insect.
