292 BRITISH LEPIDOPTBBA. 



thorax are two bristles on each side, one near the middle line centrally 

 the other forward and outside this ; the metathorax has two similar pairs 

 of bristles ; those on the prothorax, if present, are not detected. The wings 

 are attached to the 1st and 2nd abdominal segments, but beyond this 

 apparently free, the hind margin of hindwing is visible to posterior 

 border of abdominal segment 2. The wings extend to hind margin of 

 4, and further if the segments are contracted. They have a very 

 sharp apex, between which the ends of the third pair of legs appear, 

 and extend beyond them for a length barely exceeding their own 

 breadth. The second pair of legs falls short of the wing apices, and 

 the antenna; are somewhat shorter still, and the first pair of legs less 

 extended than these, the difference in length between these successive 

 points being about the same, the first legs extending for about two- 

 thirds of the wing-length, whilst between them are the anterior femora ; 

 the vertex carries two short (antenna-basal) hairs, and a pair at base of 

 labrum. The labrum is dark, square, rather narrower transversely 

 than longitudinally, and carries the usual two pairs of hairs ; the 

 mandibles are well marked ; the lower border of cheeks, mandibles, 

 and labrum, form a fairly transverse line ; the maxilla) are triangular, 

 the apical as well as the two basal angles being sharp ; the labium, 

 separated from maxillae for its whole length, is very narrow basally, 

 widens greatly to end of maxilla and then terminates in a rounded 

 end ; the central incision is short, and the two sides closely op- 

 posed, so as to allow the end, as above stated, to be in one 

 curved sweep. The dorsal head-piece is a very small strip, 

 barely chitinised, only along the posterior edge. Female (described 

 from a dehisced specimen) : Of the Macro-Psychid type, with 

 the dorsal hooks (anterior) of the 4th, 5th, 6th and 7th abdo- 

 minals developed. Free segments 3-7, incision between 2-3 dor- 

 sally only ; colour rather dark brown, especially dorsally ; small in 

 thoracic region. (The pupa wants the head-parts which are attached 

 to the imago.) Length 5mm. The 4th and 5th abdominal segments 

 are very similar to one another, they have about 30 spines or hooks 

 towards the anterior margin of the segments ; the outer ones are small 

 and evanescent, and are not in very strict alignment ; medially they 

 are raised in a slight degree above the general surface, on a ridge, and 

 have fine bracket-like ridges proceeding forwards from each hook, 

 giving a longitudinally striated surface, with numerous fine points 

 between the stria? ; outwardly the striae fail, and only the fine points 

 occur all round the anterior margin of the segment ; behind the hooks 

 are transverse ridges (or furrows) about 22 in number, which fail 

 laterally, the venter being quite smooth (apart from markings yet 

 to be noted), the intersegmental membrane succeeds this and consists 

 of a hexagonal pavement, with a denser point in the centre of each 

 lateral plate. The spiracles are slightly dorsal of an exact lateral line, 

 on small conical eminences ; ventrally are the circles representing the 

 prolegs. Dividing the space between the spiracle and proleg into three 

 equal spaces are two hollows, not altogether unlike the prolegs in 

 appearance, the more dorsal being at the posterior margin of the segment, 

 the other situated medially. The hairs are as in larva — i towards 

 middle of segment, ii at posterior border of segment half-way between 

 i and dorsal line, iii some little way exactly above spiracle, iv and v 

 close together, at same horizon, the posterior with stronger hairs, vi
