NEW BRITISH SPECIES IN 1854. 71 



Alis anticis nitidis croceis, linea tenui basali, costam versus fusco- 

 marginata, strigulis quatuor costae, tribus dorsi, introrsum fusco-margi- 

 natis, albis nitidis, striola apicis elongata, atra ; squamis albis dorsi prope 

 basim nullis. Exp. al. 4 lin. 



Head dark tawny. Face and palpi white. Antennae fuscous. Ante- 

 rior wings bright saffron-yellow, with a narrow shining white basal 

 streak, dark margined towards the costa, and with four short costal 

 streaks, and three dorsal streaks shining white, internally dark mar- 

 gined ; between the first dorsal streak and the base of the iving the usual 

 white scales on the inner margin are totally wanting ; in the apex is an 

 elongate black spot, round which runs the dark hinder marginal line ; 

 cilia whitish. Posterior wings grey, with paler cilia. 



LITHOCOLLETIS CAVELLA, Zeller. On the 11th 

 of January, 1853, I bred a specimen from birch leaves col- 

 lected at West Wickham ; and not knowing to which species 

 it should be referred I put it on one side for future investi- 

 gation. Subsequently showing the specimen to Mr. Wil- 

 kinson he recognised it as an insect he was in the habit of 

 taking on the Addington Road fence, and Mr. Douglas took 

 many specimens there last spring. The species is rather 

 conspicuous from its large size, and the first dorsal streak is 

 less obliquely placed than usual, and frequently uniting with 

 the short first costal streak forms an angulated fascia. 



Alis anticis croceis, linea basali, non obscure marginata, strigulis qua- 

 tuor breviusculis costae, tribus longiusculis dorsi, introrsum fusco-margi- 

 natis, albis nitidis ; prima dorsi ac prima costae saepe fasciam angulatam 

 formantibus ; striola apicis nigra. Exp. al. A\ lin. 



Head saffron yellow. Face and palpi white. Antennae whitish. An- 

 terior wings saffron yellow, with a shining white basal streak, with no 

 dark margins, and with four short white costal streaks, and three longer 

 dorsal streaks, internally dark margined; the first pair not unfrequently 

 unite, and form an angulated fascia; above the apical black spot are a 

 few white scales; beyond is the fuscous binder marginal line; cilia pale 

 ochreous. Posterior wings grey, with paler cilia. 



NEPTICULA WEAVERI, Douglas, n. sp. ; (see 

 frontispiece, fig. 5) ; the larva was found by Mr. Weaver,
