FUMEA CASTA. 329 



ridge ; spiracles distinct ; abdominal segments 8-10 turned ventrally ; 

 the anal segment terminated on either side by a hooked point ; dorsal 

 spines very conspicuous on segments 4-8 ; meso- and metathorax and 

 wings very shiny and smooth. Ventrally : The head-piece forms a 

 sort of transverse ventral flange ; the eyes prominent ; the antennae 

 paler, segmented, extending to apices of forewings ; between the latter 

 the 3rd pair of legs extend ; the face-parts present a somewhat oval 

 (the long diameter transverse) labrum, with the cheeks and mandibles 

 slightly lower than it on either side and with their lower borders in a 

 nearly transverse line. There are the usual two hairs on either side 

 of the labrum and one on face above it. The maxillae and labial palpi 

 project below this. The maxillae are not separated from labium to 

 the base and their rounded ends are free from the margins of the 

 labium, so that there are four rounded processes pointing downwards 

 (backwards), the two maxillae laterally and the two divisions of labium 

 centrally— the latter twice the distance of former from edge of cheek. 

 The 1st femora are well marked, nearly twice length of labial palpi, and 

 have a slight lateral mark basally ; the 6th and 7th abdominal seg- 

 ments much contracted ventrally, less so, however, than 8-10, which 

 are almost obsolete except for the anus and ventro-anal hooks. [The 

 colour of the pupa almost entirely black, the abdomen least dark with 

 brownish intersegmental rings. Imago emerged almost as soon as 

 description completed.] The pupa-skin of the wings almost yellow, 

 finely pitted, that of the abdominal segments wrinkled trans- 

 versely, pale yellow-brown in colour ; spiracles small, raised on slight 

 elevations with a circular base, the scars of prolegs very distinct ; 

 the seta? appear to be as in larva ; a dense transverse row of short 

 black hooks on 3-8, rather towards anterior edge, points turned back- 

 ward, collected into a large projecting mediodorsal point, covered with 

 hooks on the anterior edge of the 8th abdominal ; a marked series of 

 triangular, medio-lateral depressions at front edge of each segment ; 

 each segment also has an almost circular depression below the spiracle, 

 in a line with the triangular depression (these evidently due to modi- 

 fication of lateral flange (Described June 11th, 1899. Pupa from 

 Mecklenburg- Schwerin). ? . The female pupa is pale brown, 

 slightly darker dorsally, and especially on the metathorax, and less so 

 on wings and surrounding parts ; free segments, as in all ? Psychids — 

 2-3 free dorsally, with branching of incisions into 3 laterally; 3-4-5- 

 6-7 incisions free ; rows of spines along dorsal margin of 4, 5, 6, and 

 7 ; on 6 and (especially on) 7 the row broadens centrally, in a distinct 

 patch, 4 or 5 deep on centre of 7. Intersegmental reflexed spines very 

 marked on 5-6 and 6-7, less so on 4-5 ; spiracles very distinct, especi- 

 ally that on 7 ; prolegs well pronounced as wrinkled circles ; wings to 

 middle, 3rd legs to posterior margin of 2nd abdominal segment ; hairs 

 of tubercles all easily seen, trapezoidals i and ii partially reversed, iii 

 above spiracle ; a very minute one immediately in front and above 

 spiracle, iv and v some way below spiracle, the posterior being the more 

 dorsal ; vi below these ; vii is a solitary hair, then three in a row exist 

 above the proleg, the lowest close to and above it, the other two 

 upward and forwards of it ; ventrally one hair on either side. On 

 abdominal segment 7 — ii and one of the three in proleg row appear to 

 be missing ; on 8 are four strong dorsal hairs, i and ii rather spines 

 than hairs, and on 9 six in a transverse row, also very strong ; 10 is
