102 [May, 



a house at Crowborougb, Sussex, by Dr. F. J. H. Jeiikinson. Up till 

 now only two genera of Echinopsocinae were known, namely Ecliinop- 

 socus Enderl. 1903 and Scolopama Enderl. 1906. The former was 

 discovered in New Guinea (.E". erinaceus Enderl.), the latter in Ceylon 

 {S. halterata Enderl.). The discovery of this third genus in Europe is 

 therefore astonishing, and one cannot altogether rule out the possibility 

 that it may have been accidentally imported into England, particularly 

 as the creature, though indeed small, is nevertheless remarkable from its 

 covering of scales and striking coloration, and would otherwise almost 

 certainly have been already recorded. 



Table of genera of suhfamily Echi>'OPSOCINAe. 



1. Radialis not toucliing the media at any point. Axillaris and subcosta not 



developed. Media two-branched. AViug with quite Huntly-rounded 



apex I'teroxanium Enderl., uov. gen. 



Kadial-ramus touching the media. Axillaris and subcosta developed. 

 Wings acuminate 2. 



2. Media two-branched. Basal section of radial-raunis completely reduced. 



Wings very sharpl^y drawn out at apex Echi?iopsoci(s Enderl., 1903. 

 Media three-branclied. Basal section of radial-ramus present. Wings 

 moderately sharp at apex Scolopamu Enderl., 1906. 



Earn. LEPIDOPSOCIDAE. Subfam. ECHINOPSOCINAE. 



Pteeoxanium, nov. gen. 



[Type: P. squamosum, nov. spec, England.] 



Antennae 2 + 22-segmented, the flagellar segments slender, becoming 

 gradually longer towards the apex ; each flagellar segment, except the 

 apical segments, a little dilated at the end. Eyes with rather long 

 pubescence. Prothorax very short, compressed from front to back, and 

 somowhat drawn up dorsally in the form of a lamella, so that it reaches 

 over the mesothorax. Wiiic/s scale-shaped, curved like elytra, and reaching 

 to the apex of the abdomen : rather bluntly rounded at the apex : sub- 

 costa [sc.) not developed : ?-i and rr forming a handle nearer the base 

 thau the middle, rr not forked : radius nowhere united Avith media {m) : 

 media (7^(1 and nii) two-branched: cubitus (c«i and cwa) forked: analis (a«) 

 distinct : axillaris {ax) not discernible. A fairly broad border round the wing- 

 margin, and the veins, are set with large, stout, perpendicularly erect bristles 

 (the hollow cups in which tliey are inserted are indicated in fig. 2), wliich are 

 set with a certain number of microscopically fine, obliquely upstanding, points 

 (fig. 6). The wings are set witli asymmetrical scales, one side of whicli is 

 straight, the other curved (fig. .3); the longitudinal fluting on these runs a 

 little obliquely to the straight side of the scale. Besides scales the wings bear 

 also hairs of the same length as the scales, and all gradations between scales 

 and hairs. Hind ivings apparently quite absent. Tarsal claws slender, with a 

 sharp tooth near the apex.
