 G. If this species be really distiuct from A. halterata, Thomson (a species recorded 

 as British by Mr. Marshall, in the " Annual " for 1874), it may be added to our lists ; 

 but, from observations I hare made, I believe it is merely halterata with the vrings fully 

 developed. The typical halterata occurs vrith the wings in a rudimentary condition, 

 the stumps only being present. Now, last summer I caught a specimen which agrees 

 perfectly with halterata in size and coloration, but with one wing fully developed, 

 and the other represented by the stump as in Thomson's insect ; and as this specimen 

 quadrates exactly with the description of melanogaster, it seems to me clear that the 

 one must be merely a form of the other. I feel quite satisfied that the wings are 

 not torn off in the process of capturing ; with all the specimens that I have taken, I 

 noticed before touching them that the wings were not present in their entirety. 

 Thomson does not describe melanogaster, nor Hartig halterata. If I am correct iu 

 what I say, the last mentioned name must be quoted as a synonym of melanogaster, 

 Ilartig's name having the priority. In the collection of the Rev. T. A. Marshall, 

 there is a specimen of halterata scarcely half the usual size, but apparently it is 

 truly that insect. It appears to me, from the above discovery, highly probable that 

 the other sub-apterous insects of this genus may be only forms of other species with 

 the wings torn or dropped off ; for, judging from my specimens of halterata, it seems 

 likely that they had the wings fully developed when they assumed the perfect state. 



The following TenthredinidcB may also be included in our lists : — 



Nematus consohrinus, Vollenhoven, Tidjs. Ent., 2nd ser., vi, p. 237, pi. 10. 

 This is the gooseberry-feeder mentioned in vol. x, p. 21, of this Magazine. It has 

 since been bred by Mr. J. E. Fletcher of Worcester. 



N. allipennis (Klug), Ilartig, Blatt- u. IIolzw., 196, 22 ; Thomson, Ilymen, 

 Scand., i, 88, 8. Dairy, Dr. Sharp. 



N. ahietinus, Dahlbom, Consp., 9, 86 (1835), ^= N. alietum, Ilartig, I. c, 210, 

 44, pi. iv, figs. 11, 12, &c. ; Thomson, I. c, 106, 31. Tenthredo pini, Retz, De Geer ; 

 iV. Saxesenii, N. compressus, Uart. ; N. hospes and N. limhatiis, Dbm., are synonyms.

N. punctulatus, Dbm., Consp., 9, 89 ; Thorns., I. c, 117, 42, = N. leucotrochus, 

 Ilartig, l.-c, 193, 18. 



JV. crassus. Fallen, I. c, 106, 41 ; Thom., /. c, 123, 40. Not rare in England 

 and Scotland on aspens. It is doubtfully distinct from N. vicinus, Lep.,and caruleo- 

 carpus, Ilartig (which is, I fancy, the same as brachy acanthus, Thorns.), recorded in 

 Stephen's Illustrations and the Brit. Mus. Cat. 



JV. hyperhoreus, Thomson, I. c, 127. Bracmar, Dr. Sharp. 



N. striatus, Ilartig, I. c, 191, 14 ; Thorn., I. c, 131, 57. Bred from Salix fusca 

 growing at Fossil Marsh. 



N. humeralis, Zettcrstedt, Ins. Lapp., 351, 41 ; Thonis. I. c, 132, 5. Worcester, 

 Mr. J. E. Fletcher. This is, I feel certain, merely a black variety of N. striatus, 

 and hence can scarcely be regarded as an addition, but its occurrence in this country 

 is of interest.
