T. marginata, Mg. : I do not clearly recognise this species ; all 

 I have seen are probably only varieties of T. lateralis, Mg. ; "Walker's T. 

 marginata is certainly something quite distinct, possibly T. vittata, Mg. 



T. vernalis, Mg. : a decidedly common species about the beginning 

 of June ; my specimens range from May 15th to June 22nd ; I notice 

 that I have no localities north of Newmarket. The collector will 

 soon learn to know the peculiar wing-markings of this species. 



T. vittata, Mg. : the Kev. E. K Bloomfield has given me a pair 

 of this handsome species, which he has found near Hastings. It is 

 interesting to notice the similar plan upon which are arranged the 

 apparently widely distinct wing-markings of T. vittata, gigantea, and 

 lutescens. 



T. oleracea, L., and paludosa, Mg. : whether ours are the true 

 representatives of these two much vexed species, I cannot say ; I 

 believe our T. oleracea is quite identical with the Austrian species, 

 but they do not seem to recognise our T. paludosa on the continent. 

 Possibly, our two are only seasonal forms, as, although they widely 

 overlap, I find T. oleracea an earlier insect than T. paludosa, say May 

 to August, as against July (rarely June) to September; both are very 

 common, and represent the destructive " Crane Ely," the best remedy 

 against which I believe to be "rooks." 



T. selene, Mg. : most probably British, but at present unknown 

 to me. 



T. fascipennis, Mg. : after obtaining a single specimen from Mr. 

 J. H. A. Jenner, who caught it near Lewes, I found it abundantly at 

 Dickleburgh in Suffolk, at the end of June ; I know of other localities 

 in Kent and Hampshire. 



T. peliostigma, Schum. : in this group, in which I record four 

 British species, we have probably at least ten, as far as one can judge 

 from what Loew's investigations of the genital organs of the male 

 have produced on the continent ; I certainly know of another well 

 marked species which I cannot name, and which is not uncommon ; it 

 is well distinguished by its blackish legs, besides the genital characters. 

 The species which I believe to be. true T. peliostigma is not uncommon 

 in my garden in July, and, I believe, occurs not uncommonly else- 

 where. 



T. ochracea, Mg. : this is undoubtedly the commonest of the 

 "ochraceous" group, but under it also undoubtedly are lumped many 

 species ; there is room here for any amount of study.
