Dysmachus porcellus, Speiser. 
Schwed. Zool. Exp. Ost-Afrik. p. 102 (1910). 
A series of males and females from S. and E. slopes of 
Kenya, 6000-7000 ft., and on edge of Forest, Brit. E. Atrica, 
This species belongs to the group represented by D. chal- 
coyaster, Wied., also containing D. suillus, to which Speis:r 
suggests itisrelated. Itis distinguished from D. chalcogaster 
by the genitalia of the male, which are short and stout. 
Wings largely brown at the apex. 
Length, ¢ 18-22, 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 hind 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. Scuted/um with bristly black 
hairs and on outer border witlylong yellow bristles, in the 
female these latter are often black. For further particulars, 
see Speiser’s description.
