as its flight-time." My first fly I bred on October 1st, and four on 

 the 3rd, since that time I have not bred any ; but on cutting open two 

 galls I found in each a full fed larva, I presume, therefore, that some 

 pass the winter in the larva stage.

A NEW BEITISH DIPTERON: CEROPLATUS SESIOIDES, Wahlb.? 

 BT FREDK. C. ADAMS, F.Z.S. 



As far back as July l7th, 1894, I took on one of the windows at 

 Pern Cottage, Lyndhurst, a small " Daddy," which I submitted to Mr. 

 E. E. Austen for identification. After careful examination he informed 

 me it belonged to the genus Ceroplatus, and he had little doubt the 

 species was sesioicles, Wahlb., but he did not like to speak positively 

 from a single specimen. This was a $ , and on September 3rd this 

 year I obtained a ^ , which was also found on another window of the 

 same cottage. Thinking Mr. C. W. Dale might have some types of 

 this genus in his large collection, I wrote to him, and he informs me 

 he has only G. lineatus, F., which = Platyura laticornis, Mg. This 

 is a well marked insect, figured on Tab. 8, fig. 19, of Meigen's Diptera, 

 and my specimens differ from it in every respect, except the distinctive 

 broad antennae and venation of the wings, Mr. Verrall gives Q. 

 lineatus, F., in italics in his list, to which I think " sesioides " may now 

 be added.

DESCRIPTION OF THE LARYA OF CARADRINA AMBIOUA. 

 BY GEO. T. PORRITT, P.L.S. 



As is well known, Caradrina ambigua occurred in great profusion 

 along the South Devon Coast in 1897. One of some specimens which 

 I received alive from Mr. C. M. Mayor, of Paignton, on August 21st 

 had deposited a few eggs in the chip box, and these were supplemented 

 by more each of the two following nights. They were placed in 

 irregular patches, were " urchin "-shaped, and strongly ribbed from 

 summit to base. When first deposited they were pale straw colour, 

 but on the second day a distinct brown spot appeared on the apex, and
