NARYCIA MONILIFERA. 139 



"Ind. Ent.," fig. 1590 (1839). — Alis anticis atris, fascia obsoletissima, ante medium, 

 punctisque marginalibus albidis. Exp. al. 4-5 lin. Anterior wings deep black, with a 

 very obscure whitish fassia a little before the middle, and some minute dots of 

 similar hue on the costa and inner margin. Posterior wings fuscous, immaculate. 

 Metropolitan district in June, not common (Stephens). 



/3. ab. ochracea, n. ab. — The spots on the forewings ochreous instead of white. 

 This is Zeller's var. b, diagnosed (Linn. Ent., vii., p. 363) as: 

 " Signis al. ant. ochraceis $ ." He writes of it : " Two males from 

 Brunswick are noticeable for their somewhat larger size (21;"' in length 

 of forewings), for the clear ochreous-yellow of the rather sharp 

 markings of the forewings and legs, for the yellower colour of the 

 antennae, and for the black palpi which are only whitish at the extreme 

 tip." 



Comparison of Narycia monilifera with N. astrella. — X. astrella 

 has not yet been described as British. So little is known of it that it 

 may perhaps be advisable to give the original description of it : — 



Narycia astrella, H.-Sch., " Sys. Bearb.," v., fig. 320 (1851) ; p. 89 (1854) ; 

 Zell. " Linn. Ent.," vii., p. 365 (1852) ; Hein., " Schmett. Deutsch.," p. 35 (1870) ; 

 Staud. and Wocke, "Cat.," p. 267(1871). — Xysmatodoma astrella, m., Sppl. pi. 

 xlvi., fig. 320; Zell., "Linn. Ent.," vii., p. 365. Cinereo-fusca, albo-irrorata, 

 fasciis duabus obsoletis albidis, ciliis basi albopunctatis, apice albo quadri- 

 sectis. Grosser als melanella, die Vorderfiiigel gegen die Wurzel etwas schmaler, 

 die Stirne und das erste Fiihlerglied immer weissgrau, die Grundfarbe der Vorder- 

 fiiigel nicht so dunkel, mehr grau als schwarzbraun. die weissen Punkte zahlreicher 

 unci daher zwei deutlichere Binden bildend. Die Endhalfte der Franzen mit vier 

 sehr bestimmten weissen Flecken. Die Stirne und das erste Fiihlerglied innen sind 

 deutlich weissgrau behaart. Von Fischer-R., aus Beichstadt in Bohmen (Herrich- 

 Schaffer, Sys. Bearb., v., p. 89, pi. 46, fig. 320). Heinemann adds : "Beinerz, end 

 of June." 



N. monilifera specially differs from N. astrella in the black-haired 

 head, the yellow-ringed antennae, the smaller and less elongated fore- 

 wings, as well as in the markings, which, only in the ? , sometimes 

 form two transverse lines, but which do not, as in N. astrella, form 

 two broad shades (" clouclbands ") (Zeller). 



Ovum. — The egg is '46mm. in length and rather over -33mm. in 

 Avidth, almost circular in transverse section ; a well-rounded oval in 

 outline, full yellow in colour, surface very smooth, regular and un- 

 sculptured. Laid by an unfertilised ? , a few woolly hairs amongst 

 them, June 16th, 1899. 



Case. — The cases (full-grown) average about 5 - 5mm. in length 

 and 2mm. in width, somewhat rounded dorsally, but with a flat face 

 resting on the surface ; some cases circular, others almost trigonal in 

 section ; one end almost pointed, the other end blunter and rounded ; 

 composed of whitish silk, thickly covered with minute particles of sand 

 and yellow lichen, which give the cases a yellow colour. [Described 

 June 15th, 1899, from cases from the Cheddar Bocks] . Not quite 

 full-grown cases measure about 5mm. in length and 15mm. in 

 width ; they taper to a rather narrow pointed anal end, the mouth 

 slightly constricted and lipped; opening almost ventral; made of 

 whitish silk: much curved dorsally, rather flat ventrally, but with a 

 nearly cylindrical section. Covered with fragments of lichen (Bacot. 

 Cases from Cheddar Rocks). Bacot further notes of cases from Tar- 

 rington, " the lateral ridges well-marked, and slightly developed medio- 

 dorsal ridge, but the cases are not regular in shape and vary somewhat 

 inter se. These cases are covered with fine, rather bright green, tree
