A. brumpti 33 



short and strong; coxa I (Figs. 39, 41) separated from coxa II by an 

 interval equal to their breadth ; coxae II, III and IV contiguous ; all 

 coxae have their anterior and posterior borders covered by striated 

 integument ; tarsi (Fig. 45) with a spiniform protuberance which gives 

 them a bifid appearance. 



Origin : Description (condensed from Neumann) based on 35 

 specimens collected by Dr Brumpt at Ogaden, Somaliland. 



Note: Dr Brumpt having kindly sent us a specimen of A. brumpti % 

 (Dakhatto Valley, Somaliland), we have been able to compare it with 

 Neumann's description. We have figured our specimen (Figs. 38, 39).

Nymph : Body flat, 5 x 25 mm., with lateral borders parallel, rounded 

 posteriorly, tapering anteriorly to a short rounded point; colour 

 reddish, capitulum and legs yellowish white. Integument folded, with 

 very fine granulations, covered with whitish hairs, excepting on the 

 venter between coxae. A distinct striated margin visible dorsally and 

 ventrally; a dorsal protuberance corresponding to the capitulum; 

 symmetrical depressions occupied by discs. Venter very prominent 

 centrally. Sexual orifice punctiform, between coxae I. No eyes. 

 Capitulum twice as long (1 mm., including base) as broad, the base twice 

 as broad as long, resting on a broad transverse fold equal to twice its 

 breadth ; hypostome long, narrow, pointed, lanceolate, with numerous 

 teeth anteriorly, followed by dentition 2 | 2, not extending to the middle 

 of its length. Legs fairly long ; coxa I stout, thick, somewhat separated 

 from coxa II ; tarsi without protuberance. 



The description (modified from Neumann) is based on a specimen 

 (late-stage nymph) collected at Utengala, German East Africa, by 

 Fulleborn (Berlin Mus.). This species is unfortunately not figured.
