The latter at any rate answers to Ids description, and is so common in 

 all Scandinavia (vide Tliomson) that he must siu-ely have Icnown it. 

 Hence I acqmesce in the name employed for it on the Contment. 



triceps, Th.— This is not mentioned in the Monograph, but it 

 appears to be at least as common in this cotmtry as pratensis. Besides 

 the characters given above in the Table, I find a siibstantial difference 

 between the ? saws of iericeps and jjratensis, which bears out Thomson 

 and Konow in treating the insects as specifically distinct. 



Palustris, Kl.— I never took this species in England myself, but 

 have received it from several correspondents. The ? is easily recog- 

 nised by the black thorax, being much smaller than any other simi- 

 larly coloured female. (Its saw is hardly distinguishable from that of 

 pratensis). The (J nmch resembles that of pratensis, but the prmctu- 

 ration is of quite another style. 



Bimaculatus, Geoff.— This s^ecies = tristis, KL, which is .mentioned 

 by Mr. Cameron, but apparently not considered by him to be British. 

 I possess, however, a ? taken by Col. Yerbury in Scotland, which 

 quite agrees with my foreign specimens, and was determined for me as 

 liimac^datus by Konow. 



ChappeUi, C— I do not retain this m my Table, because having 

 carefully examined the solitary recorded specimen (in the Cameron 

 Collection at South Kensington) I find that its mesonotum is not (as 

 stated by the author both in his synopsis of species and in. the descrip- 

 tion) " black," but entirely, though obscurely, red. I have not the 

 slightest doubt that it is only a maclidus ? in exceedingly bad 

 condition. 



Gessneri, Andi^e.— The types of gessneri (C.) at South Kensington 

 belong to this species ; but the figiu-es of the " saw," &c., in the 

 Monograph (PI. xix) bear no resemblance to the actual saws in balsam 

 in the Cameron Collection, and must have been di-awn by mistake from 

 somethino- else — probably from a saw of Loderiis palmatus. 



Scoticus, Cam.— The saw of the type in the Cameron Collection is 

 quite identical with that of gessneri, and is figured faii'ly correctly in 

 the Monoo-raph. I do not doubt that the insect is a small and 

 probably immatiue ? of gessneri. It is certainly not, as suggested 

 formerly by Dr. Enslin, a Loderiis — the eyes being short ! 



Gonager, F. — This is by far the commonest species of the black 

 forms with red on the legs. I have a (British) ^ with [n.b.] the 2nd 

 cubital nerve present in both wings (four cubital cells !).
