162 NEW ENIGMAS FOR SOLUTION. 



47. A Gelechia? larva mining down the stems (near the 

 root) of Car ex pahidosa, collected at Wicken Fen, near 

 Cambridge, April 30th. These were very young, and all 

 died. Some local Entomologists may be more successful in 

 rearing this species. 



48. A larva mining in the stems of the shoots of Rhamnus 

 frangula, near Guildford, causing the leaves to droop ; col- 

 lected May 21st, 1858. It was imagined that this would 

 have produced Laverna Rhamniella, but the larvae all es- 

 caped or died. 



49. A grotesquely minute, pistol-form Coleophora case, 

 collected by Mr. Gregson, on Salix fusca, at the end of 

 May. These only produced ichneumons. 



50. A Tortrix ? larva mining down the stems of Centaurea 

 nigra, and ejecting its "frass" from a hole in the side of the 

 stem ; collected by Mr. Boyd at Probus, in Cornwall, June 

 19th (see Int. iv. p. 151). 



56. A Lithocolleiis larva mining the underside of the 

 leaves of Helianthemum vulgare, collected near Ratisbon, 

 Bavaria, by Herr F. Hofmann, at the end of June. I only 

 reared one miserable cripple, which was unrecognizable ; it 

 appears to be new. 



57. A Gelechia ? larva feeding inside the flowers of Cam- 

 panula persicifolia was collected by Herr O. Hofmann (then 

 at Erlan^en) at the end of June. None were reared. 



58. A Cosmopteryx? larva, found by Mr. Scott, near 

 Middlesboro' on Tees, July 12th, mining down the midribs 

 of the leaves of Centaurea Scabiosa, making a small blotch 

 on the upper side, and ejecting its black excrement. I suc- 

 ceeded in getting one larva into pupa, which subsequently 

 presented me with an ichneumon! 



59. A Gelechia ? larva feeding in the fruit of the barberry
