44 Mr. H. Eltringham's Monograph of the 



A. rabbaiae rahhaiae. 



^. Expanse about 64 mm. F.-w. transparent. H.-w. trans- 

 sparent or thinly scaled. Nervures well marked, dark brown. 

 A more or less well-marked series of black spots across centre 

 of f.-w. confluent round the discocellulars. One crescentic 

 spot in 2, below junction of 3 and the median. One spot below 

 this and slightly nearer base, in lb, and another, more rounded 

 spot in same area, near junction of 2 and the median. One 

 spot in area 11 just before end of cell. Apices slightly dusted 

 with brownish ochreous. H.-w. more or less scaled with 

 whitish. Margin with large internervular ochreous spots bor- 

 dered inwardly with a blackish siiffusion. Underside the same. 

 Thorax black with a few reddish spots above and spotted with 

 pale ochreous below. Abdomen black with pale lateral spots 

 and brown beneath. Claws unequal.

The extent of the scaling of the h.-w. in rabbaiae varies 

 from a condition approaching transparency to a fairly 

 thickly scaled surface. These scales are, in all the exam- 

 ples I have seen, distinctly paler in colour than in the 

 subsp. mombasae. 



A. rabbaiae mombasae, subsp. 



This form resembles rabbaiae but the black markings in the 

 f.-w. are less well defined and the h.-w. is always thickly 

 scaled with creamy brown scales distinctly darker than in 

 rabbaiae. The apices of the f.-w. are darker and frequently bear 

 traces of a marginal band of pale spots. 



The example of this form figured and described by Grose-Smith 

 has both wings moderately scaled and this is apparently the 

 case in the remaining examples in his collection. Most of the 

 specimens I have seen show a greater transparency in the f.-w. 



The form appears to be confined to the neighbourhood 

 of Mombasa, Rabai, and Zanzibar. I have seen no speci- 

 men of the typical rabbaiae taken so far north as this. The 

 latter occurs at Delagoa Bay and inland to Chirinda. 



The genital armature is the same in both forms. 



The type is in the collection of M. Oberthiir. The larva 

 of rabbaiae is briefly referred to by Mrs. Monteiro in 

 "Delagoa Bay" as "bright red with black spines."
