The larva lias the upper part of the head brownish-black, divitled 

 at the top by a paler stripe (but Bome want this pale baud, whilst 

 others have the back portion also pale) ; the lower part is whitish- 

 gx'cen, with a somewhat semi-circular fuscous or pale brown mark in 

 the centre of the face ; the mouth is deep brown ; the mandibles 

 darker. The black eyes are situated in the pale portion. The feet 

 are glassy-white ; the thoracic feet have the claws and the joints next 

 to these pale brown. Each of the body segments (except the fifth) 

 is provided with a pair of feet — twenty-two in all. The upper part 

 of the body to the spiracles is dark drab-green, assuming a brighter 

 tint when the creature is filled with food ; the remainder is white. 

 The body is of the ordinary Tenthredo type ; the skin closely wrinkled. 

 The usual length of the larva is about nine lines. 



The pupa is bright glassy-green, with the wings, antenna?, and 

 feet white. 



In addition to describing fjlahratiis (under the name of Allantus 

 agilis, Kl.), Stephens gives another species of Taxonus — T. rujipes, 

 Ziegler — which Mr. Smith also, in his Nomenclature of British 

 Ilymenoptera, adopts as a distinct species ; but, from the description, 

 I should say that it is merely glahratus without the bronzy tint, for 

 otherwise there seems to be no difference between the two.

British oalc-gaUs. — In the Entomologists' Annual for 1872, Mr. Albert Miiller 

 gave twenty-two species of CynipidcB as depcnclcnt upon the oak in Britain, all of 

 whicli I have found in this neighbourhood, with the exception of Biorhiza aptera, 

 Triffonaspis meffaj)tera, and liryophanta longiventris. Two of these species, viz. : 

 B. aptera and D. longiveutris, I have no doubt occur here, but I have at pi-esent 

 failed to find them ; as to ^. aptera, I have had but little chance, not having met 

 with any uprooted trees ; A. radicis, the other root-gall of the oak, I have found 

 rather commonly at the roots of hedge-stubs. 



Since the publication of Mr. Miiller's paper, four other species of oak Cynipidce 

 have been added to the British fauna, viz. : Andricus qtiadrilineatus, Hart., A. 

 amenti, Gir., and Spathogaster vesicatrix, Schl., by Mr. Traill (E. M. M., x, 39 and 

 85) ; and Aphilothrix solitaria, Fonsc. (= C.ferruginea, Hart.), by Mr. Cameron 

 (E. M. M., X, 85) ; of these I have found A. quadrilineatus hero abundantly this 

 spring. 



I now add descriptions of four ofher species found here, one of wiiich — A. 

 globuli — has been recorded as British by myself in the Entomologist (vii, 24). 



Drt/ocosmus cerrijyJiilus, Gir. — I found a cluster of old fallen galls of this species 

 at the root of an oak — Q. pedunculata — here on the 22nd of June Inst. Dr. Mayr 

 says : " this rare gall is only found on Q. cerris," and he, like myself, liad only seen
