348 Mr. R. I. Pocock on Three neio 



He lias given his consent to nij publishing the present paper 

 in advance of his own. 



The insect appears to be most nearly related to the 

 American genus Lepthemis, to wliich it was originally re- 

 ferred by Mr. McLachlan, but it differs widely in the armature 

 of the legs. From Orthefrum snhina, Diury (a rather aber- 

 rant species in its genus), with which it has considerable 

 external resemblance, it differs in the absence of supra- 

 triangular nervules, the usually discontinuous last antenodal 

 cross-nervule of the fore wings, and the much broader triangle 

 of the fore wings. From Sympetnim^ which it resembles in 

 the shape of the triangle of the fore winas and in the upper- 

 side of the triangle of the hind wings being distinctly sepa- 

 rated from the lower sector of the arculus, it differs in the 

 much longer wings, with much more numerous cross-nervures, 

 and the long slender abdomen, much more distinctly inflated 

 at the base. I am unable to refer the species to any of the 

 foregoing genera, and therefore think it best to propose a 

 new one for it wnthout further delay. 



XL. — Descriptions of Three new Species of Spiders of the 

 Genus Selenops, Latr. By R. I. Pocock. 



Selenops oculatus^ sp. n. 



Colour (specimen rubbed). — Carapace pale castaneous, 

 with greyish-white hairs at the sides ; eyes surrounded with 

 black pigment; legs bright ochre-yellow, with indistinct dark 

 bands on tibiaj ; abdomen testaceous, with yellowish-white 

 hairs above. 



Carapace much higher than in >S'. radiafus, a little wider 

 than long, its length equal to length of protarsus of fourth 

 leg, barely equal to length of tibia of either second, third, 

 or fourth leg. Four median eyes close together and 

 forming a strongly recurved line, the inferior edge of the 

 posteriors a little higher than those of the anteriors, about on 

 a level with their centres; the posteriors much larger, about 

 twice the diameter af the anteriors ; distance between the 

 anteriors equal to about half their diameter, but twice as 

 great as that between the anteriors and posteriors ; anterior 

 lateral eyes on a level with inferior edge of anterior medians ; 

 posterior laterals very large and prominent, their diameter 

 at least one third greater than that of the posterior medians, 

 a little more than their own diameter above the inferior 

 margin of the carapace.
