Mutilla (Pycnotilla) andromeda var. melanotica Bischoff. 



Somaliland : Sheikh Hussein, one female (A. Donaldson Smith. - 

 Academy of Natural Sciences, Philadelphia). 



This spécimen was recorded by Fox under the name Mutilla 

 sinuata Olivier (Proc. Ac. Nat. Sci. Philadelphia, 1896, p. 547). 

 It agrées well with Bischoff's description. As in some other Pycno-
