SARROTHRIPA REVAYANA. 



Plate CLXI, fig. 4. 



On the 14th and the 19th of June, 1881, I received 

 in all six larvae feeding on oak, from the Rev. John 

 Hellins. 



The length of most of them seemed to be about 

 from five-eighths to three-quarters of an inch ; they 

 were of moderate substance and cylindrical in form, 

 only the last segment being a little tapered. Their 

 colour was a bright yellowish green, showing deep 

 yellow at the segmental divisions and at the front 

 margin of the second segment, which is generally a 

 little paler green than the rest of the body. The 

 head has the least possible tinge of red and is slightly 

 paler than the rest of the body. This larva is remark- 

 able for bearing very long fine hairs, those on the 

 thoracic segments being directed forwards over the 

 very rounded head, and all the others directed back- 

 wards ; the spiracles are orange red. The skin though 

 soft and velvety has yet a degree of transparency, and 

 the segmental folds admit of considerable extension. 



When full-fed it spins a delicate whitish inverted- 

 boat-shaped cocoon to some solid substance. (William 

 Buckler, 1881 ; Note Book IV, 48.) 



TORTRIX EORSTERANA. 



Plate CLXI, fig. 5. 



On the 31st of May, 1876, were found between 

 united leaves of young ivy and under turned-down 

 corners of some of the ivy leaves, nine or ten larva?, 

 much like the shape of a Pyralis, excepting the ventral 

 legs, which were not long enough. 



The larva is seven-eighths of an inch long, very 

 nimble in wrisforlins: backwards and forwards Tortrix-
