134 THE ENTOMOLOGIST. 



dorsum of the metathoiax, shining black, with white cenchri ; 

 the tegulae above the insertions of the wings are orange ; 

 the legs are yellow, excepting the tips of the anterior and 

 middle tarsi, which, together with the apices of the posterior 

 tibiae, are brown ; the posterior tarsi are darker, being almost 

 black. The posterior tibice are broader than is usually the 

 case in this group of Nemati, and are deeply channelled 

 externally. The abciomen is entirely orange, the dorsum of 

 the 1st segment being incised; the extremities of the anal 

 projections are, however, black during the life of the insect; 

 the ovipositor also appeared to me to be of the same tint. 

 The wing-nervures are yellow at the insertion, then brown or 

 black, the transparent wings themselves being strongly 

 iridescent. The stigma is fuscous. 



It appears to me as very probable that there is more than 

 one brood of this species in the year. A female of Tryphon 

 Vepretorum, Grav., proceeded from one of the cocoons : so 

 far as I am aware this parasite has not hitherto been 

 considered indigenous. 



One-third oj the British Butterjlies in a wood near 

 Watlington. By Thomas P. Lucas, M.B. 



One lovely morning, early in August last, we started from 

 Watlington on a visit to one of the adjoining woods. The 

 weather, which had long been unfriendly to the lover of 

 science, had at length cleared, and we found ourselves in a 

 blaze of sunshine, mellowed by a gentle breeze, and inter- 

 rupted only at intervals by a passing cloud. Nine miles from 

 the railway, this rural spot afforded uninterrupted seclusion 

 for hosts of whinchats and other small birds ; the turtle dove 

 appeared to be very common. On our way we passed by the 

 debris turned out of a well, which had recently been sunk in 

 the chalk marl : this yielded a rich supply of delicately- 

 marked white fossils, — Terebratulse, Rhynconellus, Wald- 

 hermias. Oysters, Echini, Sponges, &c. On a higher level 

 are quarries in the lower chalk and lower beds of the upper 

 while chalk, each containing a lew fossils to reward the 

 diligent student. Round these quarries were crowds of 

 thistles, — Carduus acaulis, C. nutans, C. Forsteri, Carliua
