Hcspcrodryimis gen. nov. 



This new genus is proposed for three slender and elongate 

 species, evidently allied to Paradryimis. All are of a ferruginous 

 or testaceous colour, with short, but functional, wings, which 

 are banded. The head is of peculiar form, being acutely wedge- 

 shaped posteriorly, the hind margin when the head lies back, 

 resting over a considerable part of the pronotum and entirely 

 concealing the prolongation of the prothorax in front of the 

 pronotum. Consequently, when seen from in front, the hind mar- 

 gm of the head is well rounded and extended far back behind the 

 eyes, the posterior ocelli being placed well behind an miaginary 

 line joining the hind margins of the eyes. In Paradryinus, when 

 the head is viewed from in front, the hind margin is nearly 

 straightly transverse and the posterior ocelli generally about on a 

 line with the hind margin of the eyes. The pronotum is strong!} 

 compressed at the sides posteriorly, so that it is there bluntly 

 cariniform, its sculpture and that of the head is very dense and 

 minute, the surface being cjuite dull. Otherwise the genus greatly 

 resembles Paradryinus, the maxillary palpi with four long joints 

 beyond the geniculation, the two basal ones, as usual, less dis- 

 tinctly divided, the basal ap])arently less chitinized and perhaps 

 more or less fused to the maxilla. Laliial palpi three-jointed, the 

 apical ore very long and cylindrical. The front legs are formed 

 much as in Paradryinus, Init are rather stouter; the second joint 

 of the tarsus is very small, the third much longer, but still much 

 shorter than the fourth ; the chelar claw of one species differs re- 

 markably in structure from that of the others ; the lamellate den- 

 ticles of the fourth joint are well developed and reach or nearly 

 reach back to the articular cavity. 



The males of two species are known, and these may l)e easily 

 distinguished from those of Paradryinus by the eyes having com- 

 paratively few and short hairs, hardly noticeable imder a strong 

 lens, and by the nnich less conspicuously hairy antennae. In 

 both species the femora and tiliiae are black, while m all tlie
