as the second, as long as or a little shorter than the following joints taken together. 

 — Long. 2mm.-2-5mm., North and Middle Europe, common." 



All these points of difference (except the metasternal lines) I had 

 noted in my letter to Mr. Donisthorpe, as well as two others which 

 the above description does not mention. The earlier joints of the 

 antennte are evidently more slender than in A. seiiiuuiltiiii, and the 

 club is pitchy instead of being unicolorous. The posterior femora are 

 longer, so that their apices project beyond the margins of the elytra, 

 and exhibit the characteristic tooth. 



In conclusion, I desire to acknowledge my indebtedness to Mr. 

 Donisthorpe for his courtesy and help. 



jEiOTES ON LIFE-HISTORIES, LARY^, &c. 



Notes on the early stages of Lampides theophrastus. — /v/,'/' 

 lai/imi : — The ova are laid singly or in couples on the terminal buds 

 of " Nabb " {Zizi/pJiKs, sp. ?) or under the younger leaves, generally 

 near the midrib. Larra :■ — When young, pale green covered with 

 white hairs. When two-thirds grown, of a slightly darker green with 

 a yellow stripe down the back for from three-fourths to the whole of 

 the length. W^hen fullfed, a reddish streak appears within the 

 dorsal stripe for from one-fourth to one-third of its length. Pupa: — 

 Dark, nearly black below, the thorax and the upper half of the wing- 

 cases greyish-ash colour, becoming iridescent violet before emergence of 

 ^ s. The pupal stage lasts, as a rule, about a fortnight (in the summer). 

 I)na;/o : — The imagines occur near the foodplant and are locally 

 common. Time of appearance : — Near Cairo, iii-iv end (probably in 

 summer) and viii-x end. Habits of iiiuuin : — Pairing, as a rule, takes 

 place on the branches of the foodplant after long preliminaries. Larcae 

 and ants: — The larvae, which eat furrows, sometimes of an inch in 

 length, on the underside of the leaf, are often attended by small red 

 ants which do not apparently harm them. I believe the ants devour 

 the excreta. Seasonal broods : — No difference {pace Spuler) is observable 

 in the imago. At Aboukir (north coast) I took a few examples in the 

 middle of May. A fresh generation appeared about June 11th, or a 

 little earlier, and abounded till August. — Philip P. Graves, Turf 

 Club, Cairo, Egypt. November IGth, 1903. 



Ovum of Selidosema ericetaria. — Eggs laid by a 5 S. ericetaria 

 caught on August 17th, 1902, were oval in outline, bright green in colour 

 when freshly laid, sculptured with rows of hexagonal cells, each cell 

 with four minute raised, dark, olive-brown knobs at four corners of 

 the hexagon. The eggs hatched on September 8th. — E. Buckell, 

 Romsey. Nocember 2nd, 1908. 



JP>RACTICAL HINTS. 



The moths on Clematis vitalba. — 1. The newly-hatched larvfe 

 of (jrennietra reriiaria can be found on, or tapped from, the 

 opened buds of (Jleiiiatis ritaiba in August and early September. 

 They are extremely small and stand amongst the stamens of the 

 flower upon which they feed, which they resemble almost exactly 

 in size and colour. As the blossom dies, and falls, the young larvte 

 adjourn to the dark stems of the growth, and gradually turn dark in
