H. sjmmlosa and H. ohtusa 477 



pointed spur slightly longer than broad ; trochanters unarmed ; tarsi 

 long, narrow, not humped; pad almost as long as the claws. 



Description based on 2 $ from Uganda, collected by E. Degen. 



Types in the British Museum. 



The species is allied to or a varietal form of H. leachi.

Fig. 413. 



Lit. and Icon. : Donitz, 1910, p. 492, PI. XVII, Figs. 11, 12 (here reproduced). 



Male (Fig. 413): Very small, colour brownish-grey. Scutum 

 1*5 X 09 ^ punctations few and fine, cervical grooves short, lateral 

 grooves absent; festoons much longer than broad. Gapitulum: base 

 broadest in front, the antero-lateral margins broadly rounded ; cornua 

 slight. The palps form a very obtuse cone (hence ohtusa), thrice as 

 broad as long ; article 2 much longer than 3, broad basally, a very slight 

 spur under article 3. Hypostome 2 | 2. Legs : coxae unarmed ; tarsus 

 IV not humped, but narrowing abruptly.

 and coxae I. Eedrawn from Donitz, 1910, PI. XVII, Figs. 11 and 12. 



Female : unknown. 



Described originally from numerous (fs from the Island of Reunion. 

 H. obtusa is a very small species of the general facies of H. leachi, but 

 distinguished from it by the different conformation of article 2 of the 

 palps, the dentition of the hypostome and by the absence of lateral 

 grooves and coxal armature. We are inclined to regard it as a 

 doubtful species (see discussion p. 467). 



Types in the Berlin Museum, co-type (N. 2816) in Cambridge.
