112 THE ENTOMOLOGIST. 



there must I fancy be a necessity — a movement, in fact — in 

 search of a locality where the food-plant in spring is earlier, 

 as suggested by Mr. Belt. At any rate, with entomologists 

 living on the spot, especially in Ceylon, we ought soon to 

 have more reliable data on the econoiny of migratory butter- 

 flies. — Henry Reeks; Manor House, Thruxton, April 9, 1 874. 



Toririx riheana and T. cerasana. — " Mr. Barrett asked me 

 whether I thought Tortrix ribeana and T. cerasana were 

 species, or only varieties. Dr. Knaggs quotes a portion of 

 my reply, and appears to infer that 1 had only once seen the 

 two forms in copulation. I have seen them so repeatedly, 

 and, as the larvae are similar, I have no doubt of their being 

 varieties of one species. — Henry Douhleday ; Epping, March 

 14, 1874." (' Entomologist'' s Monthly Magazine'' for April, 

 p. 253.) 



[When, as in this instance, two shades of colour in 

 imago are produced from similar larvae, and the two shades 

 habitually intercopulate, we must not suppose them species, 

 otherwise the species of some Tortricidae would be endless. 

 — Edivard Newman.^ 



Phycis Davisellus, Newman. — T sent a pair of this species 

 to my kind friend Professor Zeller, who informs me that it is 

 new to him, and he believes it is unknown on the Continent. 

 It bears no resemblance whatever to Albariella, and does not 

 belong to the same ^enus. — Henry Douhleday ; Epping. 



Polydrusus sericeus. — In May of last year (1873) 1 had 

 the good fortune to secure, near Crabbe Wood, Winchester, 

 a single example of the beautiful green weevil, Polydrusus 

 sericeus, Schonherr, a species which, as I am informed by 

 Mr. Janson, " though taken in some numbers many years ago 

 by the late Rev. G. T. Rudd, in a wood at Kimpton, near 

 liingwood, Hants, has not, to my knowledge, occurred since." 

 — TV. A. Forbes. 



Cryptocephalus hipusiulatus. — With regard to Cryptoce- 

 phalus bipustulatus, which I have noticed in the January 

 number of the 'Entomologist' (Entom. vii. p. 23) as occurring 

 on St. Catherine's Hill, Winchester, it may be of interest to 

 know that C. lineola, of which C. bipustulatus is regarded by 

 some as a variety, has also occurred during the past summer 

 in exactly the same locality, so that this, as far as it goes, 

 seems to show that the above view is the correct one. 1 may
