clviii Pomeranian Species 



leaf there free from them. In the open air it appears about the mid- 

 dle of May. There are two broods, the most numerous of which 

 proceeds from the autumnal larvae. The pale yellow larva mines the 

 leaf at a convenient place, and is not, like other species, confined be- 

 tween the veins of the leaf, since the veins of the sallow-leaf are fleshy 

 and easily bitten through. The epidermis is drawn together in many 

 small folds, and so forms the cavity of the dwelling ; the form of it is 

 by no means regular. The larva collects its excrement into a heap in 

 a corner, and generally forms its cocoon in the middle. The cocoon 

 is transparent and very fine, and contains a pale brown pupa. 



Note. — I bred in the winter of 1849-50, upwards of 150 specimens 

 of this species. Round Stettin it occurs at Eckerberg, abundantly, 

 and is very common at Vogelsang ; also, though scarce, it is to be 

 found at Fort-Prussia and Julo. 



10. L. capreella, Wocke (L. angulatella, Nic), n. sp. Alls artte- 

 rioribus croceis, linea baseos lorigiludinali, strigulis costce 4, 

 dorsi 3, introrsus fasco-marginatis albis, ante apicem squamis 

 nigris, capillis luteis. 

 This species is most nearly allied to L. ulmifoliella, L. Spinolella, 

 L. cavella and L. Junoniella ; from the first species it is separated 

 by the less bright saffron -yellow ground colour, by the fascia being 

 divided into two acute, angulated streaks, by the unmargined basal 

 streak, and by the apex of the wing ; from L. Spinolella it is distin- 

 guished by the presence of a hinder marginal line (though false> going 

 through the cilia), by the angulated streaks instead of the fascia, and 

 by the tuft on the head ; from L. cavella, by the deep loam-yellow 

 hairs of the head, the darker ground colour, and the apex of the wing; 

 finally, from L. Junoniella, by the unmargined basal streak, and by 

 the scales at the apex of the wing not being collected into a large 

 ocellated spot. From L. fraxinella it is certainly distinct, since the 

 first pair of spots are not united into a fascia, but always remain sepa- 

 rate, since the basal line takes up more than a third of the length of 

 the wing, and the opposite spots are so placed that the apex of the 

 dorsal spot (also in the male) is further inclined than that of the cos- 

 tal spot to the apex of the wing. 



Size of L. Spinolella, with narrower anterior wings. Face and 

 palpi shining white. Tuft of the head dark loam-yellow. Antennae 

 as in L. Spinolella. Legs white; the anterior plentifully spotted with 

 brown ; the posterior legs white ; the tibiae darker, the tarsi faintly 

 spotted ; the anterior tarsi are also spotted in the female. 



The thorax, which has a white longitudinal line, and the anterior
