EACOTIA SEPIUM. 261 



a light brown dorsal vessel. Fletcher describes the Worcester larvae 

 as " stout, brown in colour, with the head and corselet black." The 

 Brussels larva, found on lichens on trunks of trees received from 

 Fologne, May 30th, 1860, was described by Stainton (MS., F. 609), 

 as follows : — " Blackish. Head black ; 2nd segment black above ; 3rd 

 segment with a slender black plate above ; 4th segment with a small 

 black plate on each side ; a smaller black plate on each side of the 2nd 

 segment ; anal segment with a black plate. Feeds on lichens on 

 trunks of trees, keeping its case in a vertical position." Barrett's 

 description of the larva from New Forest (referred erroneously to P. 

 betulina) in Ent. Mo. Mag., xxx., p. 267, also belongs to this species. 



Pupa. — Male: Length 4-6mm., greatest width l-7mm., anterior 

 extremity to end of wings = 3- 6mm. The wings reach to the end of 

 the 6th abdominal segment, the third pair of legs a little farther ; the 

 hindwings to the middle of the 3rd abdominal, antennas to end of 4th 

 abdominal. Head very depressed forwards (Psychid-like) but placed a 

 little in front of mesothorax ; abdominal segments bent forwards 

 towards the anal end ; a waist falls in dorsally at metathorax and 1st 

 and 2nd abdominals. The 3rd-8th abdominals carry an anterior row 

 of dorsal spines, the 3rd-6th carry very fine spines on posterior 

 borders on intersegmental membrane ; tubercles i, ii, iii carry setae, i 

 just behind the anterior row of dorsal spines, ii posterior to this, and 

 one-third nearer the middle line ; the setae not at all distinct ventrally, 

 and there are more on the three anal segments ; the 8th abdominal 

 carries ventrally two round knobs on either side of the genital slit, the 

 10th carries two dorso-anal spikes slightly recurved but no ventral 

 hooks ; skin -folds above and especially below the spiracles mark the 

 lateral flange ; the spiracle on the 8th abdominal very ( marked, but 

 apparently closed. The prothoracic lip projects over the prothoracic 

 spiracle as a definite point or ridge. The antennae are broad, marked 

 with pectinations, they encroach on the second pair of legs, which 

 appear as a spindle between them and the 1st pair, whilst a portion of 

 the tarsus projects below the antennas, and the 3rd pair beyond this ; 

 the 1st pair of legs falls short of the antennae by about the width of a 

 segment ('21mm.), the 1st femora extend to about one-half the length 

 of the 1st leg ; the labium very short, the labial palpi suggest those 

 of T. tubulosa 2 ', the labial area widens below and without a central 

 line of division ends in two large rounded lobes ; the maxillae are 

 triangular, rounded at the end, but sharply pointed at outer end but 

 with no further indication of palpus ; jaws well-marked. Female : 

 Length 51mm., width l - 9mm. Viewed laterally somewhat arched, 

 the venter being faintly concave, the dorsum much curved from before 

 backwards ; and tapers to either end slightly but very regularly, the 

 ends rounded ; viewed dorsally the abdominal segments 3-6 are 

 very wide, whence the pupa tapers rapidly to either end, and especially 

 looks very narrow anteriorly, the mesothorax is, in fact, only 1-lmm. 

 in transverse diameter; abdominal segments 3 (dorsally), 4, 5, and 6, 

 free ; transverse row of anterior spines dorsally on 3-7 ; inter- 

 segmental spines very fine on intersegmental membrane between 

 abdominal segments 6-7 ; no anal spines or hairs ; proleg scars very 

 pronounced ; dorsal tubercular hairs doubtful ; the wings, legs and 

 mouthparts very distinct ; the labrum angulated ; the jaws very 

 distinct and rounded ; the maxillae very short, rounded, with no definite
