﻿248 F. W. EDWARDS — A KEY FOR DETERMINING THE 



of the type it would probably be impossible to determine which is the true costalis, 

 and so in the absence of proof of its error, 1 have allowed the name costa/is to 

 stand for this species. I agree, however, with DOnitz that A. costalis, Lw., is 

 very likely to prove the same as A. cinereus, Theo., or perhaps A. transvaalensis, 

 Carter. 



This species is in many respects a variable one, and is common throughout the 

 E thiopian region .

The statement that in this species the ''basal lobe of the genitalia''' is " divided 

 into two segments " is incorrect : the type specimen is merely broken.

Both M. funcsta var. umbrosa and M. umbrosus were described by Theobald in 

 his third volume, but the latter is better known and so the name A. umbrosus is 

 retained for it. The idea of page precedence is rejected as absurd.

This species has been confused with the dark varieties of A, funestus, and not 

 all the records of it can be trusted.

Widely distributed in the Ethiopian region, but much commoner in West 

 Africa. Some of the varieties may be characterised as follows : — 



(i) A. funestus (type form). A pale spot on the costa near the base : third 

 vein pale-scaled in the middle, sometimes for as much as one-third of its length ; 

 fringe spots distinct, 



Donitz's A. Jwbcs, from E. Africa, resembles this form, but the wings seem to 

 be rather narrower and often quite half of the third vein is pale-scaled. 

 Theobald refers to the palpi of A. hebes as " mainly white "; this is merely an 

 error of translation from Donitz's description.
