 PLATE XIII., FIG. 97. 



Stomoxys inornata, which is the darkest of all the species of 

 Stomoxys at present described, has hitherto been collected only in 

 Cameroon, where the types of the two sexes were obtained, and 

 Ashanti, where a dozen examples (two males and ten females) were 

 taken by Dr. W. M. Graham in 1907. The localities, etc., of the 

 latter specimens, which are the only ones at present in the Museum, 

 are as follows. -Obuasi, July 15th, 28th, and 31st (including a pair 

 in coitu), " on and under leaves in bush-path " ; Kumasi, October 

 21st, " on road beyond Amakoom " ; Yankumasi, December 13th, 

 " on leaf on road " ; and Adembra, December 20th, " on leaf in 

 bush-path, 9.0 a.m." Dr. Graham has kindly supplied the 

 following note on this species as met with by him : " Common on 

 all roads visited by me in Ashanti, but difficult to find owing to its 

 dark colour and habit of hiding under leaves. I have always found 

 it associated with Glossina palpalis, Rob.-Desv., to which it is 

 very similar in habits, except that it does not settle on the ground. 

 I have never seen it bite." 



In the male of S. inornata the median grey stripe on the anterior 

 portion of the thorax is usually so much reduced as merely to appear 

 like a small light spot on the front margin, while the grey stripe on 

 each side, running from the humeral callus to the base of the wing, 

 is also less conspicuous than in the female, and the wings are often 

 much darker. Notes on the differences between the female of the 

 present and that of the foregoing species have already been given in 

 the remarks on the latter.
