280 THE ENTOMOLOGIST. 



Liiiea. — William Machin ; 21, Argyle Road, Carlton Square^ 

 Mile End, London, March 15, 1871. 



Work on the Species of Coleoptera. — Can you kindly 

 inform me of a book on Coleoptera, for a beginner, who has 

 derived nearly all he knows from the chapter on Coleoptera 

 written by you in Greene's ' Insect-Hunter's Companion.' Is 

 there one published giving a description of all the British 

 Coleoptera? something after the style of your * Butterflies 

 and Moths.' — J. Wiglestvorth ; 1, Brougham Terrace, Liver- 

 pool, March 13, 1871. 



[I know of no work in which the species of British 

 Coleoptera are described except Stephens' * Manual of 

 British Beetles,' which is out of print, although a copy may 

 now and then be obtained second hand : but this work 

 differs from both my 'Butterflies' and ' Moths,' inasmuch as 

 it gives no figures of the species. — Edward Newman.^ 



Larva of Sesia Bemheciformis. — On Friday, March 3rd, 

 when making an early visit to the woods, 1 observed, where 

 the woodman had cut, some full-sized round sticks from the 

 sallow stubs: a number of orifices were exposed, which, on 

 examining, proved to be the work and habitat of a larv-a of 

 creamy white colour, one and a half inch long, or more : the 

 orifice measured about three-eighths to half an inch over, 

 beginning from the root; the larva worked upwards. — James 

 A. Tawell ; 30, Compton Terrace, Islington, March 1 , 1871. 



[I think, in all probability, the larva was that of Sesia 

 Bembeciformis. — E. Newman.] 



Museum at Clifton College. — A Museum of Natural Science 

 has been recently started in Clifton College. I shall thank- 

 fully receive any donations of Lepidoptera, however common, 

 if in good condition. Of course, all expenses of carriage, &c., 

 will be defrayed by me. — {Rev.) J. Greene; 30, Apsley 

 Road, Redland, Bristol. 



Parasites on Canaries. — I believe that the tick mentioned 

 by you as infesting domestic birds is the same as that 

 described and figured in Ruchenmeister's * Manual of Animal 

 and Vegetable Parasites' as Dermanyssus Avium, belonging 

 to tile Acarine family Gammasida), and is allied to the mites 

 we so often see parasitic upon Coleopterous insects, especially 

 upon clavicorn and lamellicorn beetles. I have compared the 

 mites found in bird-cages with the figure given of Derma-
