146 THE entomologist's record. 



worked continuously with Dr. Saunders, the director, and has well- 

 earned the reputation of being one of the best scientific entomologists 

 in Canada. 



The various positions of honour that he has held, as President, 

 Vice-president, Secretary, Member of Council of the Entomological 

 Society of Ontario, of The Association of Economic Entomologists of 

 North America, of the Royal Society of Canada, of the Entomological 

 Society of America, etc., cannot be here enumerated in detail. 

 Suffice it to say that he was President of the first and last at the time 

 of his death, and that his decease has left a sad blank in the ranks of 

 American entomologists. But to us in England, the fact that his first 

 entomological work was done in Kent — in Chattenden Roughs, at 

 Upnor, Cuxton, Cliffe, Bluebell Hill, and the neighbourhood of 

 Chatham — is of the greatest interest. It was a revelation to the 

 writer to find out, a few years ago, that the renowned Canadian 

 entomologists knew quite as much of these charming spots as he did 

 himself, that between 1871 and 1874, they were educating themselves 

 in the same manner, in the lovely woods, on the breezy hills, and the 

 dreary marshes, round Rochester and Strood, that glorious country 

 that Dickens has written up in some of his works so accurately and 

 delightfully. 



Dr. Joy adds, on the strength apparently of a single specimen 

 captured at " Great Salkeld, on April 11th, 1908, in carrion," 

 Homalium brericolli', Thorns., to the British list. It was named by 

 Deville by comparison with " a Norwegian example of H. brevicolle in 

 his collection." 



Habits of Larvae of Laertias philenor. 



By CECIL FLOERSHEIM, B.A., F.E.S. 



(1) l!esti)i(i-/iabit young : — In small companies usually of ten to 

 fifteen on underside of leaf of ArUtolochia, ranged in files like bands of 

 soldiers, with heads pointing indifferently inwards to stem or outwards 

 to tip of leaf, rests sometimes with thoracic legs clasped and fore seg- 

 ments slightly arched (but not nearly so much so as Papilio niachaon), 

 sometimes outstretched with thoracic legs touching undersurface of leaf 

 (partial rest). Even when young the time taken for moult by this 

 species, is longer than that of P. machaun, but as the larva grows it 

 seems to take longer with each moult before it begins feeding again. 



(2) On hatching the larva of Laertias philenur eats a portion but 

 not all of the ovum — ^its habit in this respect being midway between 

 that of P. niachaon and Iphiclides ajax (the base of the ovum being left). 

 It is not particular about devouring its exuviae when young (though it 

 sometimes does so). It feeds on all occasions on the underside of the 

 leaf and is gregarious ; each batch of eggs splitting up as a rule into 

 two companies of larvte [cf. antea). Whilst feeding, the larvfe touch 

 one another so that if one of them moves it sets the others in motion 

 by the imparted shock, and if one extrudes its osmaterium the rest 

 follow suit. I have never observed it to feed at night at any stage of 

 its existence. 



(3) When two-thirds grown it is still gregarious, though less so 

 than in its earlier stages, and rests usually, but not invariably, on the 

 underside of the leaves. Its anterior segments are slightly raised and 

 its thoracic legs not clasped together. When not at rest on the under-
