D.fuscida, Kl. — This is also described by Stephens (111., vii, 50, 

 2-4) ; but as Mr. F. Smith could not fiud the true fuscula (which I 

 sent to him to be compared) amoug his specimens, I suppose that 

 Stephens had quite another insect, perhaps Blennocampa pusitla, 

 which Hartig states is the $ oi fuscula ; but Zaddach has corrected 

 this error. The only example that I have seen (which was taken in 

 iu Cadder Wilderness in May) has only three sub-marginal cells as in 

 Dolerus ; and this fact makes me think that Dolerus (JPelmatopus) 

 minutus, Htg., is the same species, for it agrees very closely as regards 

 size and coloration \;\i\i fuscula, or if not, I am certain that it should 

 be placed in the same genus. If Thomson's views are to be followed, 

 D. fuscula will require to be transferred to Blennocampa. 



The Beitish Species oe Claditjs. 



Without an examination of his types, it seems almost impossible 

 to identify some of the species of Cladius described by Stephens, on 

 account of the unsatisfactory nature of the descriptions. Mr. Smith, 

 in his " Nomenclature of HjTnenoptera," gives one species of Cladius, 

 seven of Trichiocampus, and four of Priopliorus ; but, after an exami- 

 nation of a large number of specimens from England and Scotland, I 

 have not been able to identify more than five species, as noted below, 

 a number that is certainly more in harmony with the views of recent 

 authors. I have also females of what are probably G. Brullwi, Dbm., 

 and C. Drewseni, Thorns. ; but I cannot be quite sure that they are 

 correctly named until I get males. 



Cladius dijfonnis, Pz. 



C. rvfpes, Lep., = uncinatus, Htg. 



C. eradiatus, Htg., = ? morio, Lep. 



G. viminalis, Fall.,^ grandis, Lep., = luteicornis, Stc., = eucerus, 

 Htg. 



C. padi, Linn., = alhipes, Fall., Ittg., = pallipes, Lep., = ^JiVi- 

 cornis, Curt., = immunis, Ste. — This is the commonest species of the 

 genus, and it is subject to considerable variation in the coloration of 

 the legs. At the end of last October, I found a batch of the larvae 

 still feeding on the wild rose. I often get larva) without tho usual 

 black lUArk on the head. 



The Bbitisii Species of Teichiosoma. 



Our TrichiosomcB are involved in considerable confusion ; and 

 iu ordei', as far as possible, to rectify this, I give here a synonymic
