844 BBITISH LEPIDOPTERA. 



whilst the marginal (vii) is also present at the base of the legs. The 

 tubercles on the thoracic segments (and hairs arising therefrom) 

 appear to be arranged as in the other species, at least dorsally, i.e., 

 they are placed in a single line on the anterior portion of each segment. 

 The lateral flange or ridge is well marked. The spiracles are almost 

 central on the segments, except those on the 1st thoracic and 8th 

 abdominal, that on the prothorax being well towards the posterior edge, 

 that on the 8th abdominal somewhat less so ; the thoracic spiracle is 

 much larger than those on the abdominal segments, that on the 8th 

 abdominal also slightly larger than those on the other abdominals ; all 

 the abdominal spiracles are slightly raised, the surrounding area 

 darker than the skin. The segmental incisions are clearly and sharply 

 defined. The legs are neither so thick nor strong as are those of other 

 Psychid larva? examined. The prolegs are short, with an incomplete 

 circle of hooks and a slight pit in the centre of the ring ; the anal 

 prolegs have a more completely circular ring. [Bacot. Described May 

 18th, 1898, from larva? obtained by Mr. F. G. Whittle.] 



Pupa. — $ . The male (empty, imago emerged) pupa-skin is thin 

 and transparent, pale yellow in colour. Abdomen rather curved ; 

 distinct constriction dorsally at 1st abdominal segment. Spiracles 

 raised, rather subdorsal than lateral in position, placed rather anteriorly 

 on segments ; scars of position of prolegs evident. Anal segment 

 evenly rounded ; cremaster bearing two conical, spine-ended processes 

 on its ventral aspect ; these spines similar to those in pupa of Fumea 

 and other Psychids, but smaller. Sexual organs distinctly marked. 

 "Wing-cases (forewings) extend nearly to the end of the 4th abdominal ; 

 the base of the hindwings show slightly beyond forewings on dorsal 

 area of 1st and 2nd abdominal segments. A row of well-developed, 

 recurved spines is present towards the anterior edge of the dorsal area 

 of the 4th, 5th, 6th, 7th and 8th abdominal segments ; a trace of a 

 similar row but pointing forwards can be made out on the posterior 

 edge of the abdominal segments 4-7. Hairs are present dorsally but 

 they are small and difficult to locate, lateral ones are not to be detected. 

 The mouth-parts are very well developed, the face wonderfully smooth 

 and rounded, two frontal bristles as usual, labrum with four frontal 

 bristles as usual, labrum square except that the sides at lower exterior 

 angle are hollowed out by the mandibles, the chitinous septum marking 

 them off being very strong and deep, the labrum itself projects a little 

 way beyond the mandibles (downwards) which is unusual, the cheeks 

 extend a good way beyond these ; the ends of the maxilla? are very 

 rounded, about equal in length and breadth, and the labium projects a 

 little way beyond them, its extremity notched rather than bifid ; no 

 marks of antennal segmentation except waving of hind margin which 

 suggests it ; 1st legs extend a little beyond antennae, the 2nd legs,, 

 beyond these, and the 3rd legs and forewings (which terminate 

 together) an equal distance further, the fore- and hindwings both show 

 an angular tip (? remnant of Solenobiid structure). ?. The female- 

 pupa forms a smooth somewhat long cylinder, with anus rather more 

 pointed than head ; bright red-brown in colour, somewhat darker at. 

 head and anus. Length about 6mm. The thorax and head occupy 

 about one-fifth of the length of pupa. Abdominal segments 4, 5 and 

 6 free. There is no waist, abdominal segments 8, 4, 5 and 6 almost 

 equal in size, the 4th abdominal of rather greater bulk, the 6th rather
