30 THE ENTOMOLOGIST. 



(MoncreaflT). The life-liistories of the Eurytomidce are still 

 very obscure. 



Cecidomyid.e. 



Cecidomyin IrifoUi, F. Low. (Scot. Nat. i. 195). — Tn galled 

 leaflet of Trifolium repeiis and prateiise. Metamorphosis 

 internal. 



C. serotina, Winnevtz. (Scot. Nat. ii. 31, 172). — Gall in the 

 terminal bud of Hypericum pidchrum. 



C. roam, Brenii (Scol, Nat. i. 1*24) — Pseudo-gall on the 

 leaflets of Rosa caiiinn and R. villosa ; generally distributed. 



C Girandi, Frauenfeld (Scot. Nat. ii. 78). — In galled 

 leaflet of Aslragaliis hypogloUis. Metamorphosis external. 



C. Oiiohrychis, Bremi (Scot. Nat ii. 78) — Pseudo-gall very 

 like the preceding, but larger on Vicia craccn. It also occurs 

 on Onobrychia sniiva, and probably other allied .species. 



C. LntJiyri, Frauenfeld (Scot. Nat. ii. 78). — In deformed 

 leaflet of Lalhyrna prntensis, resembling the pseudo-galls of 

 the two previous species. Metamorphosis internal. 



C. PriitH, Kalt — Undescribed. In boat-shaped pouches 

 on the mid- and side-ribs (rarely on the edge of the leaf) of 

 sloe {I'rumis spiitosa) leaves; very common in Essex in June. 

 I have been unsuccessful in breeding the gall-gnats, but a 

 CalliiHome has emerged in some numbers. Metamorphosis 

 external. 



Diplosis tremulce, Winnevtz. (Scot. Nat. ii. 253). — Tn 

 smooth, pea-like, but variable galls on the twigs and petioles 

 of Popu/us trenuda. Metamorphosis internal. Kaltenbach 

 gives this species as synonymous vviih C. polyinorplia, 

 Brenii. 



Asphoiidylia pimpinfllcB, F. Low. (gall = C. pericarpiicola, 

 Brenii = C. pimpinellce, H. Low.) (Scot. Nat. i. 125). — In 

 galled seeds of Pimpinelln saxifrnga, one larva in a gall ; it 

 also occurs on Dauciis cnrota and Pastinaca saliva. These 

 galls were known to Curtis ('Farm Insects,' p. 416): it was 

 from them that he bred his Callimome Dauci. Aletamorphosis 

 external. 



Asphondylia ulicis, Traill (undescribed) (Scot. Nat. ii. 172). 

 — In galled flower-buds of Ule.v Europceiis. 



? Honnoiityift Fisc/teri, Frauenfeld (Proc. Ent, Soc. 1871. 

 p. X. ; see Entom. v. 298). — The galls on the leaves of Carex 

 [1. c.) were probably produced by this species.
