description of the larva which is given by Mr. G. T. Porritt, in the 

 " Entomologist's Monthly Magazine," Vol. XII.-, pp. 88, 89. Another 

 description is given by Mr. South, in the " Entomologist," Vol. XVIII, 

 p. 276. The larva feeds on the rose-buds or leaf-buds of one of the 

 wood species of Rosa, and either fastens a leaf by the side of the 

 flower-bud, or joins the leaves forming the leaf-bud together, and in 

 this retreat feeds either on the unexpanded flower-bud or the young 

 leaves forming the leaf-bud. The larva can be found from the middle 

 of May to the middle of July, but is exceedingly local. In the 

 " Entomologist," Vol. VIII., pp. 183 and 184, Mr. Porritt writes:— 

 " On the 26th of May last, the Rev. T. D. Daltry, of Madeley, and my- 

 self, took the larvae of Pterophonis rhododactylus very freely in a wood 

 in North Kent. Mr. Daltry soon detected it feeding just beneath the 

 leaf overlapping the rose-bud, and eating into the bud from the side. 

 Almost as many, too, were found in a similar posicion at the ends of 

 the young rose-shoots." 



Pupa — The pupae, like the larvae, vary in ground colour, being 

 greenish or yellowish, generally with a purplish dorsal line, which 

 sometimes suffuses the whole of the pupa except the swollen wing- 

 cases which are always pale ; clothed with hairs as in the larva. 

 Mr. Porritt's description of the pupa (" Entomologist's Monthly Mag- 

 azine," Vol. XII., p. 89) is : — "The pupa is about three-eighths to 

 half-an-inch in length ; pale green; the wing-cases whitish; the eye, 

 antennae, and leg-cases, also the edging of the wing-cases smok}'- 

 black." The pupa should be looked for in July, and is found attached 

 by the anal segment to the food-plant, in close proximity to where it 

 has fed, either on the peduncle, leaf-bud, or leaf-stalk. Mr. Porritt 

 found them " in the middle of July, from which they emerged in a few 

 days" (" Entomologist's Monthly Magazine," Vol. XII., p. 89. 



Figures of all the different stages of this species are given with 

 the November number of the " Entomologist," for 1885. 



Time of Appearance, &c. — The larva occurs from May to Jury, 

 changing into a pupa, as a rule, in the latter month, emerging through- 

 out July and the early part of August. This species used to be abun- 

 dant in North Kent, in Chattenden Woods, and I frequently (1873-5) 

 captured it flying around my lamp when working for other species. 

 Mr. Porritt found it fairly common there in 1875, v ^ e " Entomologist's 

 Monthly Magazine," Vol. XII., p. 88, and he also records it in the same 

 journal, Vol. XI., p. 69. Mr. Stainton, in the " Manual," mentions as 

 localities " Kingsbury and Lewisham." Mr. South, in the "Entomo- 

 logist," Vol. XL, p. 253, records : — " I have found the larvae of this
