274 Mr. R. M‘Lachlan’s Descriptions of 
clothing short and dense ; on the cubital veins, in the male, are 
tufts of raised hairs; before the middle of the wing there are 
several cell-like spaces which are entirely glabrous ; neuration of — 
the disk irregular; discoidal cell closed (in P. mimicum), with an 
additional smaller cell placed below it, formed by the presence of 
a transverse vein between the two prongs of the lower fork of 
the ramus discoidalis); the apical veins long and parallel, forming 
Jong narrow apical cells; apical forks 1, 2, 3, 4 and 5 all present. 
Posterior wings scarcely so long as the anterior and rather broader ; 
pubescence scanty ; fringes moderate ; neuration irregular; forks 
1,2,3 and 5 present. Legs moderately long, alike in both sexes. 
Spurs 2-4-4, Abdomen moderately robust. 
This singular genus differs from anything with which I am 
acquainted, especially in the abnormal arrangement of the neura- 
tion, and in the position of the wings in repose; in this latter 
condition the single species known to me bears a striking resem- 
blance to a Micro-Lepidopterous insect of the genus Depressaria.
