N. Zetterstedti, DaUbom, Clav'is, fig. 5 ; Thorns., I. o., 147, 78, = N. miniatus, 

 Hartig, I. c, 129, 12. Braemar, Dr. Buchanan White. 



These are all the additions that I can make at present to this genus, as, until 

 Stephen's collection has been revised, it is impossible to say what species are men- 

 tioned by liim, his descriptions and those of St. Fargeau being quite valueless. 



N. (Croesus) latipes, Villaret, is, I believe, British. I have not seen the perfect 

 insect, but the larva was sent me from Lancashire (I think it was from there, but 

 have quite forgotten the exact locaUty, and by whom it was taken), and this larva I 

 have still in my possession, preserved in spirits, and it is so distinct that there can 

 be no mistake as to the species. 



Macrophya albipunctata, Fallen, I. c, p. 104, 37 ; Thorns., I. c, 254, 8. Kannoch. 

 Thomson quotes M. crassulus, Klug, as a synonym of albipunctata, but this is an 

 error, as any one can see by comparing the two descriptions. 



Strongylogaster delicatulatus, Fallen, = Selandria phthisica, VoUenhoven, 

 Tidjs. Ent., 2nd ser., iv, p. 123, pi. 3, fig. 4. 



\_Limneria croceipes, Marshall (ante p. 194). The locality for this species is 

 Kingussie, not Cadder Wilderness. Uumesius crassicornis was also taken at Eingussie.

On the species of Nematus described in the Entomological Magazine. — The 

 following are the determinations (so far as I can make them) of the Nemati described 

 by Mr. Newman in the Entomological IMagazine. 



Nematus dimidiattis, vol. i, pi. 1 (larva), = Cladius viininalis, Fall. 



Fristophora cincta, iv, p. 259, := either Nematus querciis or Eriehsoni, Htg. ; 

 which, I cannot determine, as the description will fit both. 



Nematus tibialis, iv, p. 260, = N. horfensis, Hartig, Blatt- und Ilolz-wespen, 

 p. 197. As both descriptions were published in the same year (1837), I do not know 

 exactly which name should be adopted. 



Thomson (Hymen. Scand., i, p. 144) describes hortensis as having the head black, 

 with the exception of the mouth, the feet totally pale testaceous, and the abdomen 

 black only at the base ; while, according to Hartig, the vertex only of the head is 

 black, the posterior tibiae and tarsi are of the same colour, and on the dorsal surface 

 of the abdomen there is a broad black band on each segment. It is quite evident 

 that the learned Swede has described a species quite distinct from the true hortensis. 



Euura gallce, loc. cit., cannot be recognized. 



E. cynips, I. c, is in the same predicament, but it may be, perhaps, N. saliceti, 

 Fall., ^ mucronatus, Htg. — Id. 



Note on Cladius Drewseni, Thomson. — I have detected some specimens of 

 Cladius Drewseni, Thomson, Hymen. Scand., i, p. 73, 4, among a nxunber of insects 

 (from England) belonging to Messrs. T. A. Marshall, McLachlan, and Marsh ; and I 

 bohcvo I have Scotch specimens in my own collection. Wc have now, in Britain, all 

 the North European species of Cladius. 



Cladius cBneus, Zaddach, might reasonably be expected to occur in this country. 

 It is very like C. Drewseni, and the larva feeds on iSalix pentandra and triandra.
