Brischke claims to hzxe bred the male from lar\-ae of Cladius difformis 

 and, van Vollenhoven says, Dr. Wttewaall raised it in Holland, from the 

 " chrysalis " of a willow-feeding Torln'x; it is recorded by Fitch (Entom. 

 1883, p. 67) from Endopisa leplasfn'ana, a Toririx on Myrica gale and 

 galls oi Andricus terminalis; and I possess a male bred by Miss Alderson 

 on 2nd April, 1903, from forced Toririx Fnrsttrana, at Worksop. 



O. scabricida appears local or periodical in its appearance ; it was \txy 

 common in 1900, but I have hardly seen it since then ; it is usually taken 

 by sweeping the tops of herbage in the middle of June, though it may be 

 found from that time to the middle of September. It was erroneously 

 recorded by Dale (E.lM.iM., p. 68) as new to Britain in 1893 — wc find it 

 in Desvignes' Catalogue — and as occurring as Glanvilles Wootton (E.M.M. 

 1903, p. 100); not uncommon in Norfolk, at Bnmdall and the Heigham 

 osier carr, in Julv and August ; taken at light in Worcester by J. E. Flet- 

 cher on 30th July, 1876; and bred — as noted above — by W. Fletcher 

 from 7(7;'//7'.v fr5j/(7«(7 (Bridgman) ; Exminster, Exeter and Bickleigh, in 

 July and September (Bignell) ; Hastings (Bloomfield) ; Finborough Park, 

 in Suffolk (Tuck); Hastings and Abinger Hammer, near Guildford (But- 

 ler) ; Wevbridge and Blackheath (Beaumont) ; Felden in Herts. (PifTard) ; 

 Shere, in Surrey, common (Capron) ; Tarn Lodge, near Carlisle (Rout- 

 ledge); and Worksop (Houghton). I took it at Ipswich in 1894, com- 

 monlv in June at Barton INIills and Tuddenham Fen, in Suffolk and a few 

 females in August at Lyndhurst, in the New Forest.

A beautiful species, with the thorax mainly red. Head hardly narrowed

 eous spot at each orbit; clypeus (conformed exactly as in the last species), 

 face, mandibles, cheeks and palpi pale stramineous throughout. Antennae 

 filiform, somewhat slender and shorter than the body, obscurely rufescent

 Scutellum and postscutellum dull, clear red. Abdomen a little explanate 

 in the centre with the segments not elongate, black, pilose, dull and coria- 

 ccously punctate ; base of the first, and extreme apices of the anal, seg-
