way into the mines). But by no possibility could this species be mistaken 

 for the Anacampsis, nor could Parectopa robinietta. It is therefore pretty 

 evident that Dr. Fitch's Anacampsis is composed of the mine of Lithocollctis 

 robiniella, the larva of Leucanthiza ornatclla, and of an unknown imago. 

 Jt cannot be supposed that Dr. Fitch mistook a LitJiocolletis or a 

 Leucanthiza, or any other insect included in Argyromiges Curtis, for an 

 Anacampsis, which includes Gelechia and kindred genera. Dr. F. de- 

 scribes Anacampsis robiniella, and on the next page, Argyromiges pseud- 

 acaciella, and was therefore fully aware- of the difference between the 

 genera; and his A. robinietta is no doubt a Gelechia or closely allied 

 thereto. 



On two or three occasions L found in the mines of LitJiocolletis 

 robiniella, and in company with it, a much larger larva, of which 1 kept 

 no description, and which I did not succeed in raising to the imago. It 

 lived in the mine in a tubular passage or channel formed of frass, and 

 may prove to be the larva of the lost . Inacaupsis. 1 know no other 

 miners of the Locust.

Body elliptical, rather depressed, underneath black, and covered with 

 an infinity of branching or confluent wrinkles, as if scratched by a pin 

 or needle. Head black, anteriorly testaceous, between the eyes is a 

 pair of transverse red spots : antennas and palpi testaceous, dusky at the 

 tips : prothorax testaceous with an abbreviated, sub-bilobed, discoidal 

 band ; variously acuducted so as somewhat to resemble net-work : 

 scutellum ferruginous, black at the base, very minutely and confluently 

 punctured : elytra dusky, which colour, for they are really lurid or dirty 

 yellow, is produced by an infinity of transverse black lines or furrows, but 

 which at the lateral margin lose their blackness ; besides these there are 

 three rows of punctures arranged longitudinally but not regularly, the first
