clvi Pomeranian Species 



lower skin of the leaf is not laid in one stout fold, but in many small 

 folds, so that it assumes a wrinkled appearance, the leaf then appears 

 with the point recurved. The larva begins at the edges of its abode, 

 and gnaws the pulp of the leaf from the epidermis gradually round and 

 round, and often leaves some of it standing in the middle, when the 

 abode is so laid out, that the pulp of the leaf in it is more than sufficient 

 to nourish the larva till the period of its transformation arrives. Its 

 excrement is not collected, but lies scattered about ; however, before 

 its metamorphosis, the larva appears to heap it together, and fastens 

 to the heap, the fine but firm cocoon. The larva itself is stout, 2 

 lines long, pale yellow except the posteriorly interrupted green dorsal 

 streak, which however only arises from the food showing through. 

 The interruption of this streak posteriorly into separate detached spots, 

 appears to arise from the digested portions of the food, as they slide 

 down its intestines, becoming placed in small clusters. The legs of 

 the larva are pointed, greenish and yellow, transparent. Prolegs very 

 small. The body is beset with very fine hairs : the first segment is 

 not so fleshy as the following, more horny, and sprinkled with darker 

 atoms ; the sap-green colour of the back begins at the third segment, 

 where probably the expansion of the stomach begins. The larva is 

 very subject to the attacks of Pteromalinae.

This species, new to Germany, but previously observed in England 

 by Stainton, comes next to Ulmifoliella, and is also nearly allied to 

 Cavella. From this species it is easily distinguished by the darker 

 golden ground colour, the far blunter interrupted fascia, the pale yel- 

 low head, which in Cavella is always white, and lastly by the coarse 

 scales towards the apex of the wing being hardly united so as to form 

 a spot, whereas Cavella has a very fine bowl-shaped spot. 



From Ulmifoliella it is readily distinguished by the paler saffron- 

 yellow ground colour, the distinct snow-white markings at the apex of 

 the wing, and the colour of the body of the female.
