Entomological Society. 4601 



" In 1844 Col. Goureau contributed a memoir upon this subject to the Entomolo- 

 gical Society of France,* full of truth and interest, and I trust the following observa- 

 tions may throw some light upon the early stages of various families of insects. I 

 regret that several years have passed since many of the discoveries were communicated 

 to me, and those facts which fell under my immediate observation were principally 

 collected in the year 1848, in the Isle of Wight, in company with my esteemed and 

 lamented friend Dr. Win. Arnold Bromfield. 



" Anthemis Cotula. Stinking Chamomile. 



" On the 10th of August at least half the flower-heads around Ryde had the recep- 

 tacles infested by little maggots, which ate into the solid parts, giving them a brown 

 appearance when the florets were removed. They were cylindrical, shining and 

 whitish, with two very minute sharp black hooks at the head. When arrived at ma- 

 turity they contracted themselves, and assumed an oval form: they then changed in- 

 side the receptacle, or in cavities eaten on the surface, to oval pitchy pupa?, from which 

 a fly [Tephritis radiatd) emerged on the 12th of August. There were also scarlet 

 larvae of a Cecidomyia and various others, which evidently escaped my search from 

 their minuteness, as from the flowers I bred the following insects : — from the 20th to 

 the 28th August, Tephritis radiata, Fab., 9 specimens ; Cecidomyia, 2 ; Lasioptera, 3 ; 

 Phytomyza lateralis, Fall., 3. 



" The Hon. C. Harris first detected the larva? of the Phytomyza feeding in the re- 

 ceptacles of Pyrethrum inodorum.f The cocoons are elongate, cylindric, the ends 

 rounded, with two minute tubercles at the head; they are coriaceous, but very thin, 

 shining, and of a straw colour. 



" On the 22nd of September, from the same heads, I found hatched in the box — 

 Cochylis subroseana, Haw., 1 ; Phalacrus aeneus, Payk., 1 ; nov. gen. ? of Staphylinidae 

 allied to Hypocyptus ; and Pteroinalus, 2 species. 



" Senecio Jacobcea. Ragwort. 



" There were small and large maggots in some of the receptacles which were more 

 or less eaten out, the cavities being blackened with the dung of the larva?, whilst others 

 contained pupa?. 



" On the 28th of August males of Tephritis marginata, Fall., hatched, and on the 

 30th two females came forth ; also three of Cecidomyia flava, Meig. 



" The larva of the Tephritis is elongated, fleshy and yellow, attenuated at the 

 head, which is furnished with two minute black hooks, and two trifid ferruginous 

 spiracles at the tail. The pupae are oval, but curved, black and shining like polished 

 ebony. 



" Inula dysenterica. Common Fleabane. 



" The 11th of August the receptacles had been eaten into by a caterpillar, and the 

 space was covered with dung. This caterpillar could descend by a thread : it was
