gives a summaiy of some of the accounts published concerning vegetable 
excrescences caused by larvae of Cecidomyiax these he divides into true 
galls and gall-like substances. He mentions icwcnwfAemMm vulgar Pimpi- 
nella magnuy Laserpitiurn pruthenicumf Anetlimn famiculum^ and Lotus cor* 
niculatus as plants noticed by himself to be affected by the former, and Linum 
usitatissimum^ Thymus serpyllum, TJlex europamsj Sarothamnus scopariusj 
Euphorbia amygdaloides, Veronica chamcedrys, Mentha rotundifolia, Trifolium 
subterraneunij Spireea ulmaria, Poterium sanguisorha^ Mespilus oxyacantha^ 
Origanum rndgare, Mentha rotundifolia^ Lysimachia vtdgaris, Lychnis diceca, 
Prassica oleracea^ napusj and chiranthus, Ijotus uliginosus, Salix triandra, 
Pterts aquilina, Ononis spinosa, Hypericum perforatum^ and many Graminaceee 
and Synantheraceecy as observed by himself to be affected in various ways by 
the latter. He points out the impropriety of the generic name, and approves 
of the subdivision of Cecidomyia by Rondani, Loew, and Winnertz. 
Cecidomyia ceri'is, Koll., and circinanSy Gir. Galls described and figured by 
JViayr (Mitteleur. Eicheng. ii. pp. 53 h 64, t. vi. figs. 77 & 78). 
Cecidomyia hotularia, Winn. Muller (Gard. Chron. 31 Dec. 1870) notes 
economy. 
Cecidomyia fagi, Htg., tremidoi, Winn., and cauliginellay Schm. Galls from 
the Drachenfels discussed : id. Ent. M. M. vii. p. 264. 
Cecidomyia saliciperda. Economy briefly noticed by Ileylaerts, J r. ; Tijdschr, 
Ent. (2) vi. p. 39. 
Cecidomyia pictipennis, Perris, 1. c. p. 170, pi. 1. figs. 32-38, Landes (ac- 
companying larvie of Tomicus ramuloruni) ) C. pteridisy Miiller, Ent. M. M. 
viii. p. 99, England (named from the larva only, which forms galls on fronds 
of Pteris aquilina) ; C. campanidcey id. Pr. E. Soc. 1871, p. viii, Aberdeen, 
upon Campanula rotundifolia (larva only) : epp. nn. 
Diplosis equcstris, sp. n., Wagner, S. E, Z. xxxii. p. 414, pi. 4, Fulda 
(account of economy given, with figures of details of structure and of the 
earlier stages, &c.). 
Mycetophilid^. 
Sciara. Perris (/. c. pp. 167 & 168) describes, both as larvae and perfect 
insects, two species of this genus, apparently new to science, but which he 
does not name. He compares former accounts of the larvae of Sciara, and 
believes that their habits are similar to those of Ceratopogon. 
Sciophila striata. Perris {1. c. p. 140, pi. 1. figs. 12-19) describes and 
figures the early stages of this sp., bred from Dedalcea maxima (Fung.), 
comparing the economy of its larva with that of S. unimaculatay Mcq., and 
noting the apparent want of analogy between the larvae of spp. in this genus 
observed by himself to have palpi and mandibles, and those of other species 
in which these important organs have escaped the notice of former presumably 
accurate writers. 
Tiptda agarici Deg., is apparently a Sciophila : id. 1. e. p. 164. 
Mycctohia pallipes. Perris (1. c. pp. 186-190, pi. 2. figs. 47-63) redescribes 
this species in all its stages, figuring details of the larva, and fully discussing 
its economy. 
Sciara convergens, id. 1. c. p. 154 (laiwa, pupa, & im.), pi. 1. figs. 20-27,
