alluded to in the report on that order, and Thyreopws cribrarius by Mr. Bayford. 

 Of Orthoptera, Mr. Porritt showed Decticus verrucivorus, For/icula lesnei, and 

 Apterygida albipennis, taken by himself in East Kent in September ; and 

 Mr. Bayford, an example of Periplaneta australasiae from Barnsley Trichoptera 

 were represented by a case of specimens taken in the Skipton district by 

 Mr. Cribben. 



At the Evening Meeting, after the election of Officers for the ensuing year, 

 two papers were read on " Asymmetry in Coleoptera, with especial reference to 

 the specific value of Notiophilus 4-punctatus," by Mr. E. G. Bayford ; and 

 " Harvest Mites," by Mr. W. Falconer, on both of which discission ensued. —

HELP-NOTES TOWARDS THE DETERMINATION OF BRITISH 



TENTHREDINIDJE, &c. (32). 



BY THE REV. F. D. MORICE M.A., P.E.S. 



TENTHBEDOPSIS, Costa (continued from (30) Vol. XLVIII, p. 236). 



Dr. Enslin, to whom I already owe so much in connexion with 

 these papers, has just laid me under a new and quite unexpected 

 obligation. I have long been waiting anxiously for the. appearance (in 

 Deutsche Ent. Zeitschr.) of his Revision of Palasarctic Tenthredopsis 

 spp. ; and now, in answer to an enquiry when it might be expected 

 to be published, he has sent me the original MS. of his tabulation, 

 which is in the press, but not yet issued.* Consequently I feel that I 

 have no longer any excuse for delaying my own attempt to elucidate 

 the British spp. : and am now preparing Tables for the determi- 

 nation of their $ $ , soon, I hope, to be followed by similar Tables for 

 the J <$ . These Tables, however, to judge from their appearance in 

 ms., will be somewhat lengthy, and also, as it seems to me, will 

 require a certain amount of preliminary explanation to render them 

 practically useful. And as papers of more than a certain length can 

 naturally not be inserted whole in a single number, or even in two 

 numbers, of this Magazine, I fear that some little time must elapse 

 before the completed paper can be in the hands of my readers. 



Almost without exception, so far as concerns the British fauna, 

 such characters of structure — including sculpture, puncturation, etc. — 

 as have yet been utilized for the determination of Tentliredopsis spp. 

 are in one way or another exceedingly unsatisfactory. Most of them, 

 to an eye not specially trained to appreciate such characters, are quite 

 inappreciable ; and often they are only visible at all, when examined 



* Since this was printed Dr. Enslin's work has appeared. — F. D. M.
