dividing each segment into six sections ; both head and body 

 beset with minute warts or points, each wart emitting a hair. 

 Colour of the head and dorsal surface dull and rather dark 

 glaucous green ; ventral surface lighter, the division between 

 the two being very distinct, and taking place at the spiracles, 

 which are black, v^'ith a bright yellow ring : the warts on the 

 head are generally white, those on the dorsal surface almost 

 invariably black, and those on the ventral surface almost in- 

 variably white ; legs and claspers of the same tint as the 

 body, but semitransparent, Mr. Greening kindly supplied 

 me with the eggs of this species, and Mr. Buckler Vvith the 

 full-fed larvae : the latter spun a delicate web over the surface 

 of a leaf early in July, attaching themselves thereto by the 

 anal extremity and also by a surcingle passing over the body 

 behind the thorax, and thus changed into pupae, having the 

 head rather elevated and terminating in a slender point ; the 

 thorax is produced into a slender, thin, medio-dorsal keel, 

 bluntly angulaled in the middle; the sides of the 6th and 7th 

 segments keeled and angulated, the 7th more prominently so 

 than the 6th ; the following segments have a medio-dorsal 

 keel very little raised, the continuity of this with the thoracic 

 keel interrupted on the 6th and 7th segments. Colour green, 

 fading as tliey approached emergence to whitish, minutely 

 dotted with black ; the keel of thorax and lateral keel of 6th 

 and 7th segments yellow, crested with pinkish brown, the 

 posterior angle of the latter tipped with black. They emerged 

 on the 11th of July. I believe that this species never feeds 

 on the various species of Brassica, Tropa^olum and Reseda 

 frequented by its congener, Pieris E,apse, and I also think that 

 the accounts of its destructive powers are entirely fabulous. 

 Mr. Buckler remarks that all the larvae of this insect which fed 

 on water-cress produced very pretty varieties of the perfect 

 insect, the usual dusky markings of the wings being of a de- 

 licate dove-gray, the bases of the M'ings being more than 

 usually suffused vvith this tint. — Edward Newntmi. 



Description of the Larva of Tortrix vihurnana. — I have 

 lately been breeding Tortrix viburnana from larvae which I 

 first found, when very young, agglutinating the leaves of 

 Andromeda polifblia : it then accorded with the following 

 description : — Yellowish gray ; tubercles and spiracular line 

 lighter; head fulvous; 2nd segment fulvous, the hind margin
