828 THE entomologist's record. 



except the central pale dorsal line or division ; the plate on the 3rd 

 thoracic is less complete, but equally void of marking on either of its 

 lateral halves. On the forward abdominal segments there is a 

 tubercular boss, apparently representing i, but absolutely without 

 bristles ; ii is larger and has a bristle. Outside ii, and in front, is 

 the true i with a bristle, and iii is a very large boss with one bristle. 

 The ventral prolegs are circles ("?), flattened in front, with 21 to 22 hooks, 

 wanting on the inner fifth of the circle. The anal prolegs have 27 hooks. 

 The true legs have the third pair larger than the others, but less so 

 than is usual in Psychids. They have a rounded boss with long hairs, 

 inside the base of each. A development of a usual structure almost 

 into a palpus. The cast skin from one of the $ cases allowed itself 

 to be fairly well displayed, and admits of all the details of hair-distri- 

 bution, &c., being observed. On the 4th abdominal, tubercles i and ii 

 are reversed in the usual Psychid manner, ii being the larger and on a 

 larger plate ; iii has a still larger plate and one hair. Below the 

 spiracle is a larger plate (iv and v '?) with two hairs near together, the 

 posterior being a little the higher and larger. Below this a smaller 

 plate, with one small hair at its anterior angle ; below this a plate 

 that is practically part of the proleg, and carries (outside the proleg) 

 three hairs nearly in a row, from the front backwards and inwards, 

 the middle the larger. Inside the proleg is a minute plate and hair. 

 In addition to these normal tubercles there are also three very minute 

 hairs, one of which has a small plate. This lies between iii a,nd the 

 spiracle, the large plate of iii being roughly circular, but with a large 

 sinus at its lower anterior edge to contain the plate of this extra hair. 

 The other two extra hairs have no plates and are close to the anterior 

 margin of the segment, one just in front of i, the other in front of the 

 extreme ventral tubercle, but rather further out, so as almost to be 

 opposite the proleg. The hairs and tubercles of the other abdominal 

 segments are on precisely the same scheme, but have sundry modifica- 

 tions. On the yrd abdominal there is a false tubercle i, i.e., a small 

 chitinous plate without hair, related to tubercle ii, as tubercle i is in 

 most larvte except those of Psychids. This plate is larger on the 2nd 

 abdominal, and slightly more so on the 1st. On the 2nd and 3rd there is, 

 behind iii and at a little lower level, a similar plate without a hair, it 

 exists on 1st abdominal, where it is rather larger, and is accompanied 

 by a similar plate above it, and rather above middle of iii. On the 1st 

 abdominal, ii is a very large plate, and iii and the subsidiary tubercle 

 have one plate. Ventrally, the 2nd abdominal segment (having no 

 prolegs) has the double-haired plate (iv and v), the single-haired plate 

 (vi), then a large plate with two hairs at its anterior border, then a trans- 

 verse plate with a hair at either end. The 1st abdominal is the same, 

 except that this latter plate is united to its fellow of the opposite side, 

 forming a four-haired plate, apparently an approach to the consolida- 

 tion of plates here on the thoracic segments, in relation to the prolegs. 

 The 5th and 6th abdominal segments are substantially the same as 

 the 4th. On the 7th, the tubercles representing prolegs have two 

 hairs, as on the 2nd abdominal, but the ventral tubercle has only 

 one hair. On the 8th abdominal, tubercles ii are united together 

 to form a dorsal plate ; iii is a large plate carrying its proper hair, 

 the subsidiary hairs, as on other segments, and curves round to 

 the back of the spiracle, where it has another large hair.
