Blepharoptera imcripta, M ( U., Trigonometopus frontalis, Mg., 

 Sciomyza obtusa, Fin., Tetanocera laevifrons, Lw., and T. .sy//m- 

 tica, Mg., as well as the commoner species. Limnia manji- 

 nata, F., L. unguicornis, Scop., and L. ul>lih-r(i1<t, V., 

 dorsalis, F., and E. rufa, Pnz., Tetanops myopinus, Fin., 

 cfoswa lacustris, Mg., Ceroxys crassipennis, F., Chrysomyza 

 demandata, F., Trypeta jaceae, Desv., Tephritis corniculata, 

 Fin., Lauxania elisae, Mg., Piophila atrata, F., P. a$r///X 

 Mg., and nigriceps, Mg., AntJwmyza gracilis, Fin., and Z>m- 

 5^a^a unipunctata, Ztt. Trimerina madizans, Fin., taken at 

 Chippenham in heaps of cut sedge in the early spring, ZhV 

 cocerina pulicaria, Hal., Philhygria picta, Fin., and flavipes, 

 Fin., Axysta cesta, HaL, Ilythea spilota, Hal. Lipara ///- 

 cens, Mg., common all over the Fens, the larvae living in 

 the reeds and causing the large conspicuous terminal gall. 

 This species may be easily bred, but is not often caught 

 because it drops from the reeds and feigns death upon the 

 approach of the collector. Other species of Chloropidae oc- 

 curring in the Fen District include Platycephala planifrons, F., 

 Haplegis diver gens, Lw., which may be bred from the same 

 galls as Lipara lucens, the larvae living in the closely over- 

 lapping sheathes of the leaves, and H. rufifrons, Lw., which 

 at present has only been recorded from the Fens. Oscinis 

 rapta, Hal., and Siphonella laevigata, Fin., and 8. palposa, 

 Fin., Ochthiphila spectabilis, Lw., Borborus pallifrons, Fin., 

 B. pedestris, Mg., B. longipennis, Hal., B. vitripennis, Mg., 

 and B. geniculatus, Mcq., Sphaerocera eximia, Coll., Limosina 

 roralis, End., L. curtiventris, Stenh., L. ochripes, Mg., L. 

 erratica, Hal., L. nivalis, Hal., L. rufilabris, Stenh., and 

 L. vitripennis, Ztt., Phora lugubris, Mg., and P. orassicornis, 

 Mg. Species of Borboridae are exceedingly numerous in heaps 

 of cut sedge in the winter and early spring, and are very easy 

 to catch as they rarely attempt to fly, but if shaken out on 

 to a newspaper will only run towards the edge and can be 

 easily bottled ; a splendid day's collecting of this sort has been 

 known to be had on a Christmas Bank Holiday, a fine bright
