BuDOliEA RBSINEA. 



On the 12th of May last, 1886, I received from Mr. 

 Eustace R. Bankes a few larvse of a Scoparia, which 

 proved to be this species, and which he had found 

 feeding under lichens and moss growing on ash trees 

 at Corfe Castle. 



Half to five-eighths of an inch in length, and of the 

 usual Scoparia form ; body cylindrical, of moderate 

 bulk, and attenuated slightly at the extremities. 

 Head, with the frontal and anal plates, highly polished, 

 and the large round tubercles also glossy ; the 

 tubercles, together with the deeply cut segmental 

 divisions, and a slight transverse ridge on each seg- 

 ment, give to the skin a wrinkled appearance. 



The ground colour is a sort of greenish-yellow, very 

 similar, indeed, to the colour of the lichens on which 

 the larva feeds ; head, plates, and tubercles very dark 

 bronzy-brown; the front pair of tubercles on each 

 segment are larger, and closer together than the hind 

 pair ; and in young specimens the front and back 

 tubercles on each side appear to join, and so form 

 distinct, dark bronze, oblique streaks. When the 

 larva is crawling, the dark green alimentary vessel 

 shows through at the segmental divisions as the 

 dorsal stripe, but there are no perceptible subdorsal 

 or spiracular lines. 



The ventral surface and prolegs are of the same 

 colour as the ground of the dorsal area, the legs 

 ringed with darker. 



I found the first imago out on the 30th of June, and 

 others appeared at intervals afterwards. During the 

 second week in July Mr. Bankes wrote me that my 

 specimens had appeared well up to time, as the species 

 was then common with him on apple trees in an 

 orchard. (George T. Porritt. 3rd March, 1887;
