• Bold (Nat. Hist. Trans. North, and Durh. i. p. 124) describes a footless 
larva, probably Dipterous, which injured the turnips in Northumberland in 
18G4, by eating into the crown between the leaves and then passing directly 
downwards, boring a hole as large as a stout knitting-needle. From four to 
twelve individuals would attack one turnip, soon leading to its decay. 
Geldart publishes some notes on Diptera occurring in the Lake district.

Cecidomyiej?. 
Cccydomyia tritici. Canestrini and Generali have described the general 
mode of life of this species (Archivio Canestr. vol. iii. pp. 317-321) and the 
parasitism of a species of Tlatygastcr upon the larva, and of a Methoca (?) upon 
the pupa. Those parasites occur in great abundance, and, as the authors 
point out, must put a great check upon the increase of the Cecidomyia. 
Rondani (Atti Soc. Ital. Sci. Nat. viii. pp. 150-153) remarks that the in- 
sect referred to by Generali and Canestrini is Cecidomyia frumentaria (RonA.) 
and not C. tritici (Kirby), and that the parasite referred by them to Methoca 
appears to belong to the Cynipidcc. He also suggests that the Platygaster is 
really parasitic upon the latter, and not immediately upon the Cecidomyia. 
Taschenberg (Naturg. wirbell. Thiere) describes the characters and mode 
of life of Cecidomyia destructor, 1. c. pp. 145-153, pi. 4. figs. 13-17, and C, 
tritici, 1. c. pp. 153-168, pi. 4. figs. 18-20. Also of C. hrassiem (Winnertz), 1. c. 
pp. 161-162. 
Cecidomyia destructor. Fitch (8th Rep. Ins. New York, pp. 203-204) 
cites a statement leading to the conclusion that the Hessian Fly was more 
widely diffused in North America in 1779 than he formerly supposed.

by F. Smith and Inchbald, Entomologist, ii. pp. 234-236. 
Loew states (Berl. ent. Zeitschr. 1865, p. 270) that the species on which 
Wagner’s observations on the reproduction of the larvfo were made is nearly 
allied to the genus Meteropeza, but still more closely to the genus Monodi- 
crana from Amber.

Schiner refers Miastor metraloas (Meinert) to the neighbourhood of Hete-

very small. Verb, zool.-bot. Ges. in Wien, xv. pp. 87-88.
