138 OBSERVATIONS ON TINEINA.

 nubbly appearance. 



Coleophora niveicostella. For years I have sought in vain 

 for the larva of this species, but I looked for it on Legu- 

 m,i)}os(B, and particularly on Hippocrepis comosa. In June 

 last I received from Herr von Heinemann, of Brunswick, 

 two specimens of a Coleophora larva on Thymus serpyllum, 

 as being the Thymiella of Reutti. Being very anxious to 

 rear the insect, I did not venture to sacrifice one of these 

 larvGe by turning it out of its case, so contented myself with 

 havino: the <?«xe fi<rured and makino; the following: note : — 

 *' Case very similar to that of Alhitarsella, but shorter ; 

 brown, slightly curved, with a thin keel behind, apparently 

 made of pieces of mined leaf. 



" The larva eats out the whole of the parenchyma of the 

 small thyme leaves, which then drop off." 



These larvas were collected by Herr v. Heinemann, June 

 5th and 7th, several hours search rew^arding him with only a 

 few specimens. On the 31st July I bred one perfect insect, 

 and it appears to be identical with what I have in my collec- 

 tion as Coleophora niceicostella. As far as I can remember, 

 whei-ever I have met with that species. Thymus serpyllum 

 has been growing at no great distance. 



* ColeophoJYi co?igerieUa, Staudinger (Stett. Ent. Zet. 1859, 

 p. 254). Of this species I received some larvae through the 

 kindness of Monsieur Milliere of Lyon ; they fed on the 

 leaves of Dorycniiim svffruticosum, a small papilionaceous 

 plant with persistent leaves, not unfrequent in the South of 

 France and Italy. The case is made of pieces of leaves, and 

 is not very unlike the case of Coleophora Genistw ; the larva 

 bleaches the small leaves of Dorycnium, by eating out the 

 entire parenchyma ; the case being attached sometimes to the 

 upper, sometimes to the under surface of the leaf.
