NEPTICULA CBYPTELLA. 885 



" dry downs, all plain and unspotted." All these were from Purbeck. 

 He adds : "In both forms large and small examples occur." 



MINE. The mine is very curious in many ways, chiefly reminding 

 one, however, of that of X. sei>tembrdla. The larva commences it as 

 a very fine dark brown gallery, which twists a number of times in the 

 small leaflets ; this small gallery suddenly widens out into a large, 

 pale, brownish spot, often filling the whole leaf, in which the fine, 

 irregular windings of the gallery are partly or wholly lost. These 

 mines are generally found in shady grassy places in woods, rarely in 

 open meadows (Frey) t . 



LARVA. The larva is pale yellow-green in colour, the head light 

 brownish, its length over 2'" (Frey). 



FOOD-PLANTS. Lotus corniculatus, / Lotus major. 



TIME OF APPEAKANCE. The species is, according to Frey, double- 

 brooded, imagines appearing in May, June and August, from larvae 

 feeding respectively in September, October and July. The experience 

 in Britain suggests only a single brood, the imagines in May-June 

 being produced from larvte -that feed up in July- August. Thus 

 Stainton bred an imago May 16th, 1857, from a larva obtained at 

 Headley Lane, July 19th or 21st, 1856. Douglas captured imagines by 

 sweeping the herbage at Headley Lane, at the end of June, 1855, and 

 on June 23rd, 1856 ; whilst on June 10th, 1857, Stainton also obtained 

 imagines in the same locality. Fletcher found specimens on May 

 13th, 1893, near Worthing.

ORIGINAL DESCRIPTION. Trifurcula pulverosella, n. sp. Not properly 

 belonging to this genus (Trifurcula) ; but very like the preceding 

 (T. iiinnundella), only darker, and head ferruginous. Scarce. I have 

 taken it among grass in May (Stainton, Sys. Cat. lirit. Tin. and 

 Pteroplioridae, p. 30). The species was later diagnosed (Insecta 

 Hritaiinica, p. 307) by Stainton, as follows : " Alis anticis albis, 

 grosse cinereo-squamatis, capillis ferrugineis. Exp. al. 3 lin. Head 

 and face ferruginous. Palpi whitish. Antenna grey, basal joint 

 whitish. Anterior wings with coarse dark ashy-grey scales, upon a 

 paler ground ; cilia yellowish-white. Posterior wings pale grey, with 

 yellowish-white cilia. A few specimens have occurred in May and 

 June among wild apple bushes." 



IMAGO. Head reddish. Anterior wings 6-7 mm. ; pale greyish- 

 ochreous, irrorated with coarse dark scales ; cilia grey, outer half of 

 apical cilia paler. Posterior wings light grey ; cilia pale yellowish.
