82 HAUS'IELLATA. LEPIDOPTERA. 



tibide very pilose, with elongate spurs at the apex. Lar va enclosed in a case, 

 in which it changes to pupa. 



Like the preceding genus, tlie males of this have the antenna? 

 pectinated; but the pectinations, instead of being incurved, are 

 straight, subclavate, and ciliated; the wings are very transparent, 

 abbreviated, pilose, and strongly ciliated ; the females are wingless ; 

 and both sexes appear to be destitute of trophi, a broad tuft of 

 hairs alone occupying their place. 



Sp. 1. nitidella. Alis subelongatis,fusco-nitidis, margine cinerascente. (Exp. 



alar. 5—5'q lin.) 

 Ti. nitidella. Hilbner.—Fn. nitidella. Steph. Catal. No. 6035. 



Wings entirely of a bright shining fuscous, with the margins cinerascent ; the 

 anterior a little elongate, the posterior rounded: antennae and legs gray- 

 brown ; abdomen dusky. Female ochraceous-ash, with the head chestnut- 

 brown, some grayish spots on the thorax, and the apex of the abdomen woolly. 



Caterpillar rufescent or yellowish, with the head castaneous, and ^a line of the 

 same colour on the three first segments ; the case is formed of bits of grass 

 and leaves : the pupa of the male is slender, and brown ; the female stouter 

 and brownish-yellow. 



Of this species I possess a pair, taken by myself, in the lane 

 leading to Darenth-wood from the village, in July. 



Sp. 2. puUa. Alis rotundatis atris immaculatis, undique ?nargine piloso cinctis, 



nntevnis parum pectinatis. (Exp. alar. 5 lin.) 

 Bo. puUa. Esper.—Vn. pulla. Steph. Catal. No. 6036. 

 Antennae dusky, rather slightly pectinated; head, thorax, and abdomen deep 



black, the latter brownish at the sides and apex, and the former very hairy : 



wings rounded, very pilose, deep immaculate brown, with the anterior margin 



pilose, and the cilia rather elongate. 



My specimen of this very distinct species was caught by myself 

 in June, in the lane leading into Darenth-wood from Greenhithe: 

 it appears to be scarce. 



Sp. 3. muscella. Alls oblongiuscuHs obscure hyalinis, corpore atro hirto, an- 



tennis valdi pectinatis. (Exp. alar. 5^ — 6 lin.) 

 Bo. muscella. Fabricius. — Fu. muscella. Steph. Catal. No. 6037. 



Antennae dusky-black, deeply pectinated: head, thorax, and abdomen black and 

 hairy, the sides of the latter paler: wings slightly oblong, obscurely hyaline, 

 of a deep immacvdate black, with the margins darker, the fringe long and 

 dusky-black. 



Found in grassy places amongst furze : I have seen many and 

 captured several on Hertford-heath in June, and it has also been 

 taken in Epping Forest and Dartford-heath.
