IDENTIFICATION 



Both sexes have hemispherical eyes situated in a depression, 

 and are distinct from A. variegatum and A. lepidum in possessing 

 very coarse scutal piuictations. 



Male scutal ornamentation, inside the lateral groove, is 

 like that of A. lepidiim except that a small red spot may be present 

 laterally in H. pomposum , but no red color is found on A. lepidum . 



The female scutvim may be variable in length-vidth ratio, that 

 of some specimens being only as long as wide, of others longer 

 than wide; its rugosity is very distinct; it may be unornamented 

 but usually has a small white or pale spot in the posterior field. 

 /"Robinson (1926) stated that 55 are unornamented. Nevertheless 

 a number of those in the Nuttall collection, which comprised his 

 chief reference material, have ornamented spots on the scutum. 

 These, as well as others similar to them have been observed in 

 different collections ._7 



Specimens from the SiJdan referable to these characteristics 

 shovild be checked against authoritatively identified specimens from 

 the known range of A. ponyosum before this name is applied. Char- 

 acters provided here are generalized; an exhaustive survey of the 

 subject is precluded by our uncertainty over variability between 

 this species and A. variegatum , as indicated below. 



Note 



In some large collections of A. variegatum , a few robust male 

 specimens, or, more rarely, a few pygmy male specimens, may be sug- 

 gestive of A. pomposum owing to un-osually heavy scutal punctations. 

 Associated females are also more heavily punctate and may have a 

 wider scutum than normal. Jack (1942) referred to similar males 

 from Rhodesia (see REl'IARKS above). I have collected a few lots 

 of such specimens in the Sudan and in the movintains of Yemen 

 (Arabia). The most distinctive collection in this category is 

 one recently presented to me by Dr. C. B. Philip, who collected 

 it from a herd of cattle near Kabete in the mountains of central 

 Kenya. The single female has a wide scutum and is heavily punc- 

 tate but not rugose ajid the punctations are not confluent. Of
