Carpenter to the north of the above-mentioned localities have 

 already been recorded (Proc, 1921, p. Ixxxi). 



H. phlaeas ethiopica is therefore, so far as its distribution 

 is known to us, an insect of high ground in and especially 

 along the E. border of the southern section of the Western 

 Rift Valley — the valley containing the Albert Nyanza, 

 Tanganyika, and the lakes that lie between. 



Comparison of pseudophlaeas and ethiopica with each other 

 and with H. phlaeas phlaeas L. — These two African geographical 

 races are very closely allied to each other and to H. phlaeas 

 phlaeas L. Before comparing them it will be convenient to 

 quote the brief description of pseudophlaeas by H. Lucas in 

 Ann. Soc. Ent. Fr., 1865, pp. 499-500, and contained in the 

 following Note (2) : — 



" Cette variete, par la teinte pale constante de ses ailes, 

 par I'echancrure du bord terminal qui est a peine marquee et 

 par Tangle anal qui est termine en une queue assez prolonge, 

 doit former une espece nouvelle. . . ." 



Furthermore it is stated on p. 499 that the Abyssinian 

 examples " sont tres-remarquables par la teinte pale de leurs 

 ailes en dessus et en dessous." 



As regards the under surface this statement is incorrect; 

 for the pale grey ground-colour in a large proportion of the 

 individuals of phlaeas is much lighter than the reddish ground 

 of pseudophlaeas and further still from the deeper tint of 

 ethiopica. There are, of course, dark grey examples of 

 phlaeas for which Lucas' comparison would hold. 



On both upper and under surfaces ethiopica is a darker 

 insect than pseudophlaeas. This is true of the black as well 

 as the red. In addition to this general distinction there are 

 certain differences in details, some of which appear to be 

 constant while others only hold for the majority of the known 

 individuals of each race. 



Fore-wing Upper Surface. — The black spot near the anal 

 angle, and extending, when well developed, from vein 1 to 2, 

 is inwardly concave (viz. towards the base of the wing), 

 outwardly convex, in all known examples of ethiopica, the 

 character being generally strongly although sometimes very 

 slightly marked. In pseudophlaeas the outer margin of the
