194 THE ENTOMOLOGIST. 



entomologist, who may have something to say upon this interesting 

 species. — F. P. Dodd ; Warburton Street, Townsville, Queeushxnd. 



Hawk Moth Pupating on Branches of Trees. — It appears tiiat 

 my note upon Panacra lujnnriu [ante, p. 73) is not sufficiently clear, for 

 a leading entomologist in England has taken it to mean that the larvffi 

 had bored into the wood of the trees to pupate ! Naturally, he doubted 

 such a strange statement. I trust no others have read the note as he 

 did. Of course the larvie were spun up in the leaves and twigs. — F. P. 

 Dodd ; Warburton Street, Townsville, Queensland. 



ToRTRicES IN South Essex. — When reading the very interesting 

 article by Mr. Thurnall on " Tortrices in South Essex between 1855 

 and 1901," I was reminded when I reached the note on Phoxopterijx 

 myitillana that I had recently seen, lying on one of the many new 

 roads in this district, a quantity of bilberry which had been used in 

 the packing of a load of drain-pipes. Such consignments, packed in 

 the same way, are probably commonly seen at Stratford, and might 

 readily account for the importation of P. myrtillana, I might add that 

 Ortkotccnia ericetana does occur in South Essex. I have taken it both 

 at Benfleet and Shoeburyness. — F. G. Whittle ; 3. Marine Avenue, 

 Southend, June 13th, 1902. 



Food-plants of the Larva of Cnephasia sinuana, Stph. — In his 

 very interesting " List of Tortrices taken in South Essex, Mr. A. 

 Thurnall says {ante, p. 168) that he expects wild hyacinth {SciUa 

 nutans) is the only food-plant of the larva of Cnephasia (" Sciaphila") 

 silt nana, and no other food-plant is mentioned in Mr. Meyrick's ' Hand- 

 book of British Lepidoptera,' p. 589 (1895). The idea that the larva 

 confines its attentions to Seilla nutans is, however, at variance with 

 the fact, recorded by myself in Ent. Mo. Mag., ser. 2, x. 105 (1899), 

 that Mr. G. Elisha has occasionally bred a few specimens of C. sinuana 

 (together with many of C. pasivana), from spun-up flowers of Chry- 

 santheiinun lencanthemun) , collected in a wood in North Kent. — Eustace 

 E. Bankes ; Norden, Corfe Castle, June 7th, 1902. 



The Coccid Lecanopsis ouoiisi. — This species was very briefly 

 described by Signoret and Lichtenstein in 1886, and has never since 

 been definitely recognized. In Biol. Cent. Amer., Coccidae, p. 15, I 

 surmised, that it might be the Ceioplastodes niveiis (Ckll., 1893). I have 

 now received examples of it from Guanajuato, Mexico, collected there 

 by Dr. Alfred Duges, who tells me that he did indeed send it to 

 Lichtenstein many years ago, but received no reply concerning it. 

 This, I think, may be considered to settle the matter, and the species 

 will be known as CeropUistodes dughi — T. D. A. Cockeeell ; E. Las 

 Vegas, N.M., May 31st, 1902. 



Colour Changes in Larval Hairs op Arctia villica. — The influence 

 of certain foods in causing alterations in the coloration of some 

 animals is well known to everyone. As a further instance of this 

 influence in the case of one of the Lepidoptera may be of interest to 

 entomologists, I venture to record the following facts : — I have found 

 that if the larvffi of Arctia villica, which usually live on various low- 

 growing herbs, are fed entirely on sallow from the time they are 

 hatched, the hairs covering their bodies are of a black instead of the
