In the Xat. Hist, of the Brit. Lep., iv., pp. 44 et seq., is a detailed 

 account of the Eumorphid hybrids already known to science. Of 

 these one Hyles hybr. epilobii has the parentage 3' euphorbiae x ? 

 vespertilio {op. cit., p. 46). 



:ig^OTES ON LIFE-HISTORIES, LARY^, &c. 



Ovum of Thestor ballus. — Laid singly on the backs of the leaves of 

 the uppermost whorls of Bonjeania hir$t(ta, Eeichb., partly hidden by the 

 white hairs of the foodplant. Mostly placed near the apex of the leaf, 

 sometimes on the matted hairs, but usually well hidden among them. 

 Upright, tiarate, depressed at the apex, and flattened at the base, walls 

 rounded. When first laid possibly pale yellow, certainly becoming- 

 green afterwards and finally deep purple-grey. Height, 0-4mm. ; 

 diameter, 0-61mm. Sculpture : The shell is covered with a rather fine 

 net- work, which is, however, well raised above the general surface. 

 The cells so formed are mostly irregular pentagons, measuring about 

 O'OSmm., but becoming larger towards the base. There are no 

 prominences at the angles of the cells, nor any thickening of the cell 

 walls. Thus the egg difi'ers strikingly from that of Callophrys ruhi. 

 The micropylar basin is rather wide but not deep. The cells of the 

 micropylar area do not differ in shape from those on other parts of the 

 egg, but they are much smaller and more delicate. The rosette consists 

 of seven or eight cells, and is rather difficult to observe without 

 destroying the eggs. [Described April 29th, 1906, from ova sent by 

 Mr. H. Main, who received them from Dr. Chapman from the south 

 of France] . — Alfred Sigh. [In the Ent. Rec, xv., p. 122, we gave a 

 description of an egg that we had every reason to believe was that of 

 Thestor ballus. Mr. Sich says he found an egg of Callophrys ruhi on 

 the same plant as that on which the T. ballus egg he describes was 

 laid, and suggests that the egg we described was probably that of C. 

 rubi. — Ed.] . 



Foodplant of Thestor ballus at Hyeees. — I found Thestor ballus 

 abundant at Carqueiranne in 1906, and have nothing to alter, as to 

 the foodplant it there affects, that I noted in the Ent. Rec, xvii., p. 22. 

 In the cultivated patches, T. ballus takes advantage of the way in 

 which the culture benefits Anthyllis tetraphyllus as a weed. Away 

 from the cultivation, however, it specially adopts as its foodplant a 

 very hirsute plant, which may have been off'hand, but erroneously, 

 named Lotus hisindus by entomologists, and may be the plant intended 

 by that name by the authorities, who cite Lotus hispidus as the food- 

 plant of r. ballus. This hirsute plant, Mr. Raine tells me, is Boujeania 

 hirsuto, Eeichb. I fancy Lhrycnium hirsutu)u is a synonym. I found 

 one plant of this with dozens of eggs of T. ballus on it, others had 

 them more sparingly. — T. A. Chapman, M.D., Betula, Reigate.

 particular attention to Bryophila muralis and B. perla. I was much
