his specimens show the incisions with thickened edges, as in Diaspi- 

 diotus, notwithstanding that his account in the Cornell Univ. Report 

 (1883) leaves it to be understood that they are absent. 



The true A. Greenii is the species described and figured in the 

 *' CoccidcB o£ Ceylon " as A. cydonice, Comst. A short time ago I found 

 specimens o£ it on a house palm at Mesilla, New Mexico, agreeing 

 excellently with Green's Ceylon insect. The convex greenisb scale 

 with orange exuviae, as figured by Grreen, is very characteristic. I do 

 not believe this can be Comstock's cydonice. Mr. Pergande tells me 

 that the type scales of cydonice are light grey or yellowish-grey, the 

 exuviae dark brownish and covered more or less with secretion. As 

 for the ? insects, the reader may compare the figures on pp. 11 and 12 

 of my bulletin cited, that of cydonice being from one of Comstock's 

 types.

Food-plants of Gelechiafraternella, Bgl.— The Eev. C. E. Digby {ante, p. 151) 

 asks whether there is not some confusion about the food-plant of Gelechia frater- 

 tiella, because he has always found the larva on Stellaria graminea, but never on 

 S. uliginosa, which is recorded as the plant on which it is usually found. It will, 

 therefore, interest him to know that the records are quite reliable, and that in some 

 localities the larva does feed in nature on S. uliginosa ; in proof of this I may 

 mention that on May 13th, 1888, I received from Mr. H. T. Stainton some larvse of 

 this species found feeding on S. uliginosa at Lewisham, which yielded a series of 

 imagines in the following July. Again, in the Nat. Hist. Tin., x, pi. xi, the plant 

 there figured with the shoot spun together by the larva of G.fraternella is cer- 

 tainly S. uliginosa ; and as, in the account of its habits {op. eit.), Stainton says that 

 it occasionally also feeds on Cerastium vulgatum, we now know that it has three 

 separate food-plants. Mr. Digby veievs fraternella to the genus Lita, but Messrs. 

 Durrant and Meyrick both agree that Lita cannot stand as a separate genus, and 

 must be merged in Gelechia, flb.— Eustace R. Bankes, The Eectory, Corfe

Food-plants of Dichrorampha sequana, SI. — I am glad to see that the Rev. C. 

 R. Digby {ante, p. 150) calls attention to the occurrence of this species among 

 yarrow, for although I do not think it has ever yet been recorded as having been 

 bred from this plant in Britain, it also flies commonly amongst it in the only spot in 

 this district where I have ever met with it, and obviously feeds in the roots of this 

 plant, tansy being entirely absent from the locality. In Germany they seem to have 

 done better, and to have already bred it from yarrow as well us tansy, for Sorhagen, 

 in his " Kleinschraetterling dcr Mark Brandenburg," p. 137 (188G), says : "The 

 larva in Achillea and Tanacetum." — Id. : July 6th, 1898.
