280 THE ENTOMOLOGIST. 
Linea.— 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. Wiglesworth ; 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—Hdward Newman.] 
Larva of Sesia Bembeciformis.—On Friday, March 3rd, 
when making an early visit to the woods, I 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 larva 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 7, 1871. 
(I think, in all probability, the larva was that of Sesia 
Bembeciformis.—F. 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.— (Kev.) J. Greene; 30, Apsley 
Road, Redland, Bristol. 
Parasites on Canaries.—1I believe that the tick mentioned 
by you as infesting domestic birds is the same as that 
described and figured in Riichenmeister’s ‘ Manual of Animal 
and Vegetable Parasites’ as Dermanyssus Avium, belonging 
to the Acarine family Gammaside, and is allied to the mites 
we so often see parasitic upon Coleopterous insects, especially 
upon clavicorn and lamellicorn beetles. 1 have compared the 
mites found in bird-cages with the figure given of Derma-
