Insects. * 4027 



Mr. Shield discovered the larva in the spring of 1852, and this 

 year supplied me with 300 of them, of which, having reared a 

 fair per-centage without obtaining a single specimen of Satura- 

 tella, I feel convinced that the latter is a distinct species. 



Onosmella, so named by Brahm, because he found the larva upon 

 Onosma echioides ; here we find it in May and June on Echium 

 vulgare, and Professor Zeller finds it at Glogau upon Anchusa 

 officinalis. Tischer states (Treitschke, ix. 2, 219) that it feeds 

 on Hieracium Pilosella, but in this I imagine there must be 

 some error, arising either from his mistaking the young plant of 

 one of the Boragineae for a Hieracium, or from a full-fed larva 

 having quitted its food-plant, and attached itself to Hieracium, 

 or from the larva on Hieracium (at present we know of none on 

 that plant) belonging to some other species. 



Troglodytella. Under this name we have, not improbably, several 

 species mixed. Zeller, in the ' Linnaea Entomologica,' gives 

 Artemisia (vulgaris ?), on Herr Mann's authority, as the food of 

 the larva of this species, and also observes that Senator v. Hey- 

 den found two cases, probably on Tanacetum vulgare, which 

 produced var. b. In a letter however which I had from Profes- 

 sor Zeller in January last, he mentioned that Herr Schmidt, of 

 Laybach, had sent him specimens of Troglodytella, with cases, 

 which he had found abundantly on Eupatorium Cannabinum, 

 but that these cases exactly resembled those which Herr Mann 

 had found on Artemisia. In June, of this year, Mr. C. J. R. 

 Jordan found at Teignmouth some larvae of Coleophora feeding 

 on Eupatorium, and also on Inula dysenterica; their cases were 

 similar in form to those of C. Inulae, but twice the size, and from 

 them have been reared several specimens of an insect allied to 

 Inulae, but distinct. Mr. Weir, when at Pembury in June last, 

 found the larvae of Coleophora on Eupatorium, and also some on 

 Inula ; the cases were quite similar, but all small, the size of the 

 ordinary cases of C. Inulae. Mr. Weir imagined that he had 

 here the larvae of two species, but unfortunately he did not suc- 

 ceed in rearing any. Reaumur was acquainted with the larva 

 of a Coleophora on the Eupatorium, of which he has figured the 

 case, pi. 10, f. 1, 2, 3, and 6. 



Inula. The larva in May and June on Inula dysenterica, growing 

 in the shelter of hedges. Mr. Douglas has found this on the 

 road from the Norwood Station to West Wickham Wood.
