rounded, with two minute tubercles at the bead; tbey are coriaceous, but very thin, 

 shining, and of a straw colour. 



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

 Cochylis subroseana, Haiv., 1 ; Phalacrus aeneus, Pai/k., 1 ; nov. gen.? of Slaphylinidae 

 allied to Hypocyptus ; and Pteromalus, 2 species. 



" Senecio Jacobaa. 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 larvae, whilst others 

 contained pnpse. 



" 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 Uth 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 

 somewhat depressed, broadest anteriorly, the segments constricted and slightly hairy, 

 ochreous with bright brown spots on the back, caused by the intestines shining 

 through : the head was small, black and shining, with two black spots on the thoracic 

 segment ; the six pectoral feet were very minute, as well as the anal ones : the excre- 

 ment towards the tail shone through of a green colour, and there was a spot at the tip. 

 These, I suspect, are the caterpillars of a Tinea (Aphelosetia P Tnulella),* two of which 

 I bred from the flowers of the Inula on the 28th of August, and in all probability the 

 larvas feed on the seeds. 



" On the 9th of September I bred also a female of Microgaster lacteipennis. 

 Curt, ; and on the 10th Pteromalus cupreus, a male, and an ichneumon allied to 

 Trachyderma or Bassus. 



" Carduus lanceolalus. Spear-thistle. 



" On the 11th of August I found maggots in the receptacles, feeding on the seeds. 

 They were fat, barrel-shaped, but attenuated before, shining ochreous-white ; head 

 furnished with two short black hooks, the tail with a circular ferruginous space, the 

 lower margin pitchy, with two minute spiracles in the centre of the stern. The pupae, 

 which were imbedded in the woolly receptacles, were similar in form to the larva>, being 

 attenuated to the head and obtuse at the tail, and of an ochreous or rusty colour. 

 From these, on the 4tli of October, I bred a female Tephritis pallens, Wicd., and af- 

 terwards four males and eight more females.
