it; there is a horn on each side, and one over the head. 

 Would you like a specimen? — [Rev.] A. C. Hervey. 



The beetle is Typhoeus vulgaris, one of the coprophagous 

 lamellicorns ; it is common on all our heaths in Surrey. I am 

 obliged for the offer of this insect and of Medea, but I have 

 plenty of both. 



Food of Russula. — Russula feeds best upon lettuce, and so 

 does the wood tiger. I have bred them freely from eggs, a 

 continuity of broods in captivity, at least three broods in a 

 year: in every respect, according to my observation, it is 

 similar to Caja in confinement. A friend of mine was breed- 

 ing a lot of Caja at Christmas, last year, and only in a 

 regular temperature in his own house. The larva of Russula 

 makes up in the same way as Caja does. I never found 

 the larva of Russula outside, so cannot speak on that point.

Sirex Juvencus. — The insects sent by I. K. have usually 

 been called Sirex Juvencus. The great discrepancy in size 

 has frequently been noticed, but no entomologist had con- 

 sidered size as justifying the establishing of species in wood- 

 feeding insects. Three names have, however, been given to 

 these blue-bodied Sirices : — Juvencus, Nigricornis, and 

 Abietis. I express no opinion of the specific difference of 

 the insects to which they have been applied. 



Anlhophora relusa. — 1 should be much obliged if you 

 could name the enclosed bee for me in the 'Entomologist.' 

 They literally swarm on a bank about two miles from here, 

 the ground-ivy seeming to afford great attraction. They 

 make separate holes in the bank, and become very furious 

 when any one approaches. — G. H. Raynor ; St. Johns 

 College, Cambridge. 



" This bee is found in all parts of the United Kingdom ; in 

 some situations it literally swarms : there is a colony of this 

 bee in the chalk-pits at Northfleet, of such amazing extent, 

 that in the middle of April a dark flickering shadow is cast on 

 the ground from the countless numbers assembled." Thus 

 says Mr. Smith in his admirable ' Catalogue of British Bees,' 

 wherein he names this species Anthophora Acervorum, but I 

 prefer giving it the more usual name of Anthophora retusa; 

 not that 1 have gone into the matter of priority, or have any 

 inclination to do so, but because every entomologist will
