Dysmachus porceUus, Speiser. 

 Schwed. Zool. Exp. Ost-Afiik. p. 102 (1910). 



A series of males and females from S. and E. slojies of 

 Kenya, 6000-7000 ft., and on edge of Forest, Brit. E. Africa. 



This species belongs to the groui) represented by D. chul- 

 co(/a>(er, Wied., also containing I), suillus, to which Spois r 

 suggests it is related. It is distinguished from 1). ckulcoyasier 

 by the genitalia of the male, which are short and stout. 

 IFhiffs largely brown at the apex. 



Length, S 18-2.2, ? 18-21 mm. 



Speiser gives the length as 17 mm., and gives the localities 

 as Kibonoto, near Kilimandjaro, at 2000-3000 m., and 

 Meru, 3000 m. high. 



He gives the yellow colour of the hairs or bristles in the 

 middle of the bind border of head, and the middle of the 

 thorax with not very long bristles, as distinguishing it from 

 D. suillus. The moustache is yellowish, but surrounded 

 above and at sides by black bristles; in these specimens the 

 black predominate over the yellow bristly hairs, and the long* 

 curved over bristles of head are black, but yellow bristly 

 hairs are present between them. Scutellum with bristly black 

 hairs and on outer border with long yellow bristles, in the 

 female these latter are often bkiek. For further particulars, 

 see Speiser's description.
