and nearly square ; the second recurrent nerve is received into, 

 or very near to, the second sub-marginal nerve, agreeing therein 

 with N. helicinus Brischke, which is otherwise quite distinct 

 from it. 



The male has the antennae longer and thicker than in the fe- 

 male, and, moreover, reddish-brown, with the basal two or 

 three joints black. The stigma is larger than in the other sex. 

 Length 2^-2^ lines. 



N. Vollenhoveni appears to me to come nearest to N. cinerece 

 Retz., Thorns., from which it is distinguished by not having the 

 stigma in the female white at the base, by the abdomen not 

 being so decidedly testaceous beneath, and scarcely so at all 

 above; and by the second recurrent nerve being jointed to the 

 second sub-marginal nerve, or very ?iearly so. In cinerece the 

 recurrent nerve is very perceptibly distant from the sub-marginal 

 nerve in both sexes. In cinerece also the feet are sometimes 

 blackish more or less at the base, which is rarely the case with 

 Vollenhoveni. The tarsi of the latter species are also more de- 

 cidedly blackish, especially the hinder pair. The claws are the 

 same. 



I have received from Mr. van Vollenhoven a male of the 

 species described by him under the name of Nematus vimi- 

 nalis L. (see Zoologist S.S. p. 7721), and I am inclined to regard 

 it as identical with cinereaz. It is now impossible to identify 

 with any certainty Linne's gall-making saw-flies, and it is not 

 worth while discussing what species they may be. 



N. Vollenhove?ii is very much infested with hymenopterous 

 parasites when in the larval condition. 



N.B. — To the life -history of Hei?iichroa luridiventris (ante p. 158) add: 

 pupa glassy -green, with the exception of the antennae, wings, and feet, which 

 are white. The insect becomes a pupa at the end of April and enters the 

 perfect state a month after. 



To the life-history of Athalia rosa (ante p. 197) add : pupa grayish-white, 

 as observed on 25th May. 



Turtle Dove (Cohimba Turtur). — On the 28th of May last, an adult 

 female, in fine plumage, was shot at Clifton Park, Roxburghshire. Most 

 likely it would have bred in the neighbourhood — the most forward ova 

 being larger than a pea. Have they been known to breed in Scotland? 

 This is the second turtle dove got in this district lately. Vide Scottish 

 Naturalist, II. 70. — Andrew Brotherston, Kelso.
