Geo. Bedell ; 4, Waterloo Place, Coburg Road, Kent Road, April 29, 1845. 



A Gnat observed two miles from land. I once saw a midge (I know not the scien- 

 tific name) flutter in a calm day over a boat in Mount's Bay, at least two miles from 

 shore ; a more wonderful exploit, perhaps, considering the relative powers of the in- 

 sects, than that of the dragonfly recorded Zool. 950. — F. Holme. 



Parasitism of Chalcidites. 1. Pteromalus muscarum, (Linn.) The great numbers 

 of this elegant and brilliant little fly compensate for its apparent individual insignifi- 

 cance, and it is an example of the rule that the species of creatures exercise in their 

 collective capacity, a more important function in the economy of Nature, in proportion 

 as they are lower in the scale of creation. During the early part of spring it occurs 

 in abundance on windows having an eastern aspect, and is accompanied by Chlorops 

 lineata (Fab.), of which it is probably a parasite. It varies exceedingly in size, and 

 it is to be hoped that the cause of this variation may be ascertained, whether the pa- 

 rents give birth to offspring equal to themselves in size, or — if the comparative magni- 

 tude of the insect is not hereditary — whether it depends upon the quantity of nourish- 

 ment which it procures in the body of the larva on which it feeds. I have never seen 

 the male of this species, notwithstanding the profusion of the female. Eulophus Hip- 

 pia associates with the latter, and is perhaps another parasite of Chlorops lineata. 

 " The clypeus of Pt. muscarum is slightly emarginate, and the spiracles of the meta- 

 thorax are, in this genus, somewhat oblong," — Haliday, MSS. — Francis Walker.
