3. Hcspcvodryinus aiida.v sp. nov. 



Colour, form, and sculpture generally, almost as in the pre- 

 ceding two species. This is, however, of larger size, the third 

 antennal joint is black, pale only at the tip ; the mesonotum is 

 regularly and closely longitudinally rugose, the propodeum is 

 also strongly longitudinally wrinkled, with very little reticulation, 

 at least on the dorsal surface. Chelae formed and armed almost 

 as in H. arisonicns: just beyond the most apical of the spinose 

 bristles there is a slight elevation of the lower edge of the chelar 

 claw, hardly to be considered as a tooth. Length 8 mm. 



HAB. Nogales, Arizona ; one example was captured on an 

 oak tree. 



Pcrodryinns gen. nov. 



General form and structure of Paradryimts, but with the front 

 tarsi very different. The basal jomt is long and slender, as long 

 as the four following together, the second small, the third and 

 fourth subequal, the backward process of the fifth reaching to the 

 base of the fourth, and densely armed with lamellate denticles ; 

 the chelar claw a simple spine with dilated base for articulation, 

 the chelae being extremlely short. Pronotum longer than the 

 mesonotum, compressed posteriorly, but without a transverse di- 

 vision ; mesonotum without parapsidal furrows, with dense ru- 

 gose-punctate or reticulate sculpture. 



Male like that of Paradryinus but the eyes are bare, there are 

 no parapsidal furrows, the radius is short, falls far short of the 

 wing margin, and is bent at about its middle. 



Pcrodryinns aviocntis sp. nov.' 



Black, antennae, the clvpeus, the pronotum and the legs ferru- 

 ginous, the antennae subinfuscate apically. The mandibles except 

 the teeth, the basal half of the posterior tibiae, the basal jon-t 

 more or less of the middle and hind tarsi, whitish ; tips of hmd 

 femora black. 



Head and mesonotum very densely rugose-punctate or retic- 

 ulate : third antennal joint long, twice as long as the fourth. Pro- 

 notum rugulose and with pale pubescence: scutellum rather 

 smoother than the mesonotum, the propodeum shinmg, reticulate-
