Mr. Cameron identifies this sp. with ornata, Lep., with whose description it 

 certainly seems to agree pretty closely, and if he be right, this is the older 

 name. But Konow, thoixgh aware of this identification, never adopted it, why 

 I do not know ; so provisionally I retain the name he gave me. It certainly is 

 wliat Thomson called excisa, whatever else it may have been called. 



4. T. fjynanclromorpha, Rvid. This is a rare and remarkable species which 

 any one fortunate enoiigh to find it should recognize without difficulty. I never 

 took it myself in this country, nor indeed anywhere except in Greece and Corfu, 

 but it is vouched for by Mr. Cameron as occurring in Clydesdale. This, alone 

 among British Tenthredopsis spp., has the antennae ringed with white in both 

 sexes ; and (n.b.) the mesopleurse distinctly and even strongly punctured. 

 The ? (but not the ^ ) has a white scutellum. The rest of the thorax and the 

 head (including the clypeus and labrum) are usually — perhaps always ? — quite 

 black in both sexes ; at any rate they are so in all my specimens. The red 

 colovir on the ? abdomen generally extends over 5 segments. Otherwise it is 

 not iinlike coquebertii and has the same peculiarly deep shade of red. The legs 

 arc black throughout, while in coquebertii the tibise are normally somewhat 

 paler than the femora or the tarsi. The character of the distinctly punctured 

 mesopleurae occurs in several foreign Tenthredopsis spp. but in no other, I 

 believe, that has been recorded, xmless obviously in error, from this country. 

 It is probably one of more real importance, than the white on the antennae, 

 though the latter will be noticed first and at once even by a novice. 



Our remaining species of this genus I must postpone to another 

 paper. I fear I shall not be able to indicate in any of them characters 

 as distinct and positive, as those exhibited by the species diagnosed 

 above. In fact I may almost say of my own ideas about them, here 

 certainty ends, and doubts begin ! 



(To be continued). 



Parnus miglicanus, Edxv., at Wicken. — Parnus anglicanus was described for 

 the first time in this Magazine by Mr. Edwards about three years ago, from 

 specimens found at Horning in Norfolk. Last year Mr. Pool and I, together 

 with Mr. F. Muir, visited Horning, my principal object being to make acquaint- 

 ance with this species. After a good deal of search we located the ParniLs in 

 the water at the edges of one of the large ditches, and secvired a fair series. 

 The spot reminded me so strongly of Wicken that I felt sui-e the species must 

 also exist there, and I now have the pleasure of reporting that a fair series of it 

 has been procured at Wicken by that most successful of collectors, 

 Mr. C. J. C. Pool. The Wicken specimens indicate a race with the individuals 

 fully as large in size as those from Horning. 



I find that cei-tain of the species of this genus possess a very remarkable 

 character in the dimorphism of the wings, these organs being more or less 

 reduced in size in the female and of peculiar shape. Mr. Pool has kindly
