external border almost as above, but rather paler, and 

 with diffused inner edge ; veins yellowish, probably owing 

 to abrasion of the scales ; secondaries with the extremities 

 of the veins and the outer margin black, as above ; 

 tarsi banded with black. Expanse of wings, 35 mm. 



? . Differs from the male in having a rather broad 

 grey border to the secondaries on both surfaces, and the 

 whole under surface clouded with grey. Expanse of 

 wings, 36 — 37 mm. 



One male and two females. 



This species comes nearer to D. dodoncea than to any 

 other form with which I am acquainted, but the broad 

 snow-white central belt on the primaries and pearl- 

 white secondaries give it a very different aspect ; it 

 also differs from all the species of Drymonia known 

 to me in the greater length of the subcostal fork on 

 the secondaries. 



HEPIALID^. 



Callipielus, n. g. (Plate I., fig. 6). 



Form of Charagia, neuration very near to Pielus ; 

 wings ample, primaries triangular, the costal margin 

 nearly straight to apical fifth, then slightly convex to 

 apex, the latter obtuse ; outer margin nearly straight, 

 but curving round at external angle, which is con- 

 sequently almost lost ; inner margin slightly convex, 

 running abruptly inwards at the base, broadly fringed 

 throughout ; costal vein running almost to apex ; sub- 

 costal uniting at the base with the median ; the branches 

 are four in number, the first being forked towards apex ; 

 the first three, therefore, are emitted before the end of 

 the cell, and the fourth from the anterior angle of the 

 same ; the ordinary fifth branch is emitted from the 

 disco-cellulars, and thus becomes the first or upjDer 

 radial ; it starts at about the same distance from the 

 true upper radial that the latter does from the true 

 lower radial, or third radial of this insect ; the third 

 radial throws a recurrent vein through the cell to the 

 base ; the third median nervule is emitted from the 

 disco-cellulars, and consequently becomes a fourth radial ; 

 it also throws a recurrent vein through the cell to the 

 base ; the disco-cellulars form a simple zigzag or open 

 Z-shaped line; the median vein is necessarily two- 

 branched, the third having become a radial, the
