460 THE ENTOMOLOGIST. 



moth is Rivula sericealis, and the caterjDillav is the goose- 

 berry-grub, described at sucli length at pp. 148 — 154, of the 

 first voUirae of the 'Entomologist.' — Edward Newman.] 



Names of Insects. — Will you please inform me whether 

 the two flies enclosed are Neraatus ventricosus, as they 

 answer the description you have given of the goose- 

 berry-grub ? and what is the name of the little beetle- 

 looking creatures I have also enclosed .'' I found them on the 

 leaves of Scrophularia. There seems to be another brood of 

 Ventricosus, as they have begun their ravages again. — John 

 Purdue. 



[The sawflies are certainly Nematus ventricosus, provided 

 the imago of the gooseberry-grub be properly so called. The 

 little beetles are Cionus Scrophulariae. — E. Newman.]. 



Chrysomela falgida. — Will you have the kindness to give 

 me the name, &c., of a beetle which feeds on the tansy, — 

 commonly called the " tansy-beetle." — Tlios. W. Wilson ; 

 3, Bootham, York, July 11, 1873. 



[The beautiful golden green beetle feeding on the tansy is 

 Chrysomela fulgida: it occurs in marshy places in Yorkshire, 

 Cambridgeshire, and Norfolk, but I do not recollect receiving 

 it from any other county. — E. Newman.] 



The Genus Cionus. — 1 herewith send you some little 

 beetles, which I found resting on the leaves of Verbascura 

 Thapsus, and should feel greatly obliged if you would 

 kindly tell me the name of them, and anything relating 

 to their economy, as I have not got Stephens' ' Mandibulata' 

 by me just now. — Henry Reeks ; Manor House, TJiruxton, 

 June 30, 1873. 



[The beetles are Cionus hortulanus of the Stephensian 

 nomenclature, but I am not certain that they retain that 

 name in this name-changing era. It is a true weevil, — that is, 

 a member of the family or section of beetles called Rhyncho- 

 phora or Curculionida^. There are five British species of the 

 genus Cionus, all closely resembling one another in form, 

 but different in colour and in size. To the best of my belief 

 they feed exclusively on the mullein, and I have found them 

 all, as mentioned by Mr. Stephens, feeding on a single plant. 

 The egg I have never found, but it is in all probability laid 

 on the leaf of the common mullein (Verbascum Thapsus), 

 for 1 find the larvae when very small digging holes in the soft
