170 [July. 



of this very distinct species, which was bred by hiiu on 

 May Sth, 1905, from a beech {Farjus) fungus found in the 

 New Forest. It is, I believe, the third known specimen, the 

 first having been bred by Scholtz in June, 1S49, from the 

 exuding sap of a birch tree in Silesia, while the second 

 specimen was recorded by Loew in 1859 as occurring in 

 Von Heyden's collection from the neighbourhood of Frank- 

 fort on the Main. The female is still unknown, and may be 

 very distinct from the male, as the black spot at the wing tip 

 is almost certainly sexual, but it ought to have very pale 

 antennae and coxae. Schiner's description contains two 

 gross errors. 



2. S. adpropinquans Lw. : Mr F. Jenkinson first took this species 



at elm sap in his own garden at Cambridge on July 22nd, 

 1901, and then two more females in 1902, from one of whicb 

 I recognised the species, though it was not easy to do so 

 from only a female of a genus new to Britain ; in 1903 he 

 caught another female, besides breeding four males and one 

 female from an elm tree at Aldenham, Herts, and in 1904 

 he bred a considerable number of females from the same 

 sap. Laboulbene had previously bred it from elm sap near 

 Sevres, and had given full details in A.nnales de la Societe 

 Entomologique de France for 1873. The species varies very 

 much in size, and in the reddish-orange colour about the 

 base of the antennae, which is sometimes almost absent ; but 

 it and S. Sclioltzii are the only ones of the five species which 

 have the cubital and discal veins strongly approximating. 



3. S. hipartitus Lw. : I have come to the conclusion that four females 



taken by Mr. F. Jenkinson at sap (one on Elm) at Cam- 

 bridge from July 10th to August 4th, 1904, must belong to 

 this species. It is again a difficult matter to recognise it 

 from the female only, but it is easily distinguished from 

 8. adpropinquans and 8. Scholtzii by the much more 

 parallel cubital and discal veins and by its entirely black 

 antennae, and by the latter character from 8. tener ; one of 

 Mr. Jenkinson's specimens (July 10th) has a black I'ing 

 before the tip of the hind femora, which makes me think it 

 is more likely to be 8. hipartitus than 8. leucurus. The 

 female of 8. hipartitus has not been previously recognised 

 and therefore the positive identification of this species must 

 await the capture of a male.
