448 Mr. A. Murray on Coleoptera from Old Calabar, 



manni in the magnificent collection of tlic Count Mnizseck in 

 Paris. These are the following: — The antennic in my specimen 

 are not quite so much thickened ; the anterior tarsi are less di- 

 lated; the scutellum is smaller, and the posterior angles of the 

 thorax are less salient. Some of these may be mere sexual di- 

 stinctions, and the remainder possibly accidental variations ; at 

 all events, none of them, according to my views, suffice to con- 

 stitute a new species. 



Mr. Westwood, in his generic description of this insect, says 

 that the abdomen has only four segments. I would express this 

 differently. It may only have four separable segments, but the 

 segments are in reality five, the first two segments being soldered 

 together, so that their line of separation is indistinct in the 

 middle ; but it is quite distinct and well marked at the sides. 

 This appears to be the normal state of matters in the MorionidcB 

 and Scaritidce. There is also a side-piece before the first seg- 

 ment, which may be viewed as part of another segment.
