Mr. Pace so determines two or three examples collected by Mr. Townsend 

 at Bombay, and which were referred at first to C. fuscata, Sowb. This 

 last is a native of Panama, St. Elena, and Monte Christo, W. Central 

 America. It is the first record of the Mediterranean C. rustiea being found 

 beyond tlie (hdf of Suez. The examples are not quite typical, and we hope 

 a further supply may come to hand, in order that the important question 

 of its geographical distribution be more definitely studied.
