Rhyphidas. 
Rhyphus fenestralis, Perris {1. c. pp. 190-196, pi. 2. tigs. 64-61) redescribes 
this species in all its stages, figuring details of the larva, and fully discussing 
its economy. lie points out the very great similitude between the larvae of 
Mhyphus and Mgcetohiay evidently considering that these two genera should 
not be dissociated.

Von Grimm, M^m. P«5tersb. (7) xv. no. 8, translated in Ann. N. H. (4) 
viii. pp. 31-45, 106-115, pi. iii. figs. 1-12, describes and gives microscopical 
figures of details connected with the agamic reproduction in the pupa state 
of a species of ChironomuSy and its development from the unfecundated egg. 
Bree (Ent. V. p. 312) describes a shower of insects” at Bath, which, 
from an editorial note, appear to be the larvae of a ChironomuSj possibly C. 
plumosus. 
The larva of Chironomus oceanicuSy Pack., is recorded from a depth of 
20 fathoms in Eastport harbour, Maine, by Packard, in Am. J. Sci. (not 
seen by the Recorder), who identifies it with the supposed larva of Mio'a- 
calymma referred to by himself in Am. Nat. ii. p. 278. 
The larva and pupa of a TanypuSy or some closely allied genus, are de- 
scribed by Packard, 1 . c. ; they were found abundantly in salt water, Clear 
Lake, California. 
Ceratopogon, Perris (/. c. p. 138 et seq.') repudiates Bouch^’s reference of 
4 joints to the antennre of the larva of C. lateralisy as unlikely in any 
Dipteron'y he describes, for the first time, the stigmata of a larva of this 
genus, having satisfied himself that these occur as follows : — one pair on the 
prothorax and one on each of the first 8 abdominal segments. From his ob- 
servations, it appears that the larvce of Ceratopogouy though partial to 
animalized matter, such as the fr-ass ” of other larvie, are sometimes car- 
nivorous, devouring the larvfe and pupae of other subcortical spp. of insects. 
After a general discussion of the recorded facts as to the larva of this genus, 
he expresses some doubt as to the correctness of the description &c. of that 
of C. dufouri by Laboulbene, and of C. variuSy Winn., by Heeger.
