trimaculatus, Bigot, are synonyms, is a West African species, which 

 appears to be fairly common in Sierra Leone and Ashanti. The 

 Museum collection contains : a female from Sierra Leone, before 

 1842 (Rev. D. F. Morgan) ; a second female from Sierra Leone, 

 1893 (Surgeon-Captain W. G. Clements) ; five females from 

 Freetown, and Regent, near Freetown, Sierra Leone, September 

 2nd and 13th, 1899 (E. E. Austen] ; two females from Sierra 

 Leone, August 12th, and October, 1904 (Major F. Smith, D.S.O., 

 R.A.M.C.) ; three males and four females from Obuasi, Ashanti, 

 June, 1906, and June 20th, September 8th and 21st, October, and 

 November 13th, 1907, and one male and two females from Kumasi, 

 Ashanti, October 22nd and 27th, 1907 (Dr. W.M.Graham, W.A.M.S.}\ 

 and one female from Bonny, Southern Nigeria, May 23rd, 1900 (Dr. 

 H. E. Annett). A pair of Dr. Graham's specimens from Kumasi were 

 taken in coitu ; a male from Obuasi is labelled " caught on flower 

 of composite plant " ; two females from Kumasi and Obuasi were 

 captured in bush-paths, one on the under side of a leaf at 2.0 p.m. ; 

 and three females from Obuasi were caught on a window in a ward 

 of a disused hospital (September and October, 1907). 



With regard to the behaviour of C. longicornis in Ashanti, Dr. 

 Graham supplies the following note : " This species hovers about 

 one in shady bush-paths, and also hides under leaves, when it is 

 difficult to find ; I have never observed it bite anyone."
