banded abdomen, and the slender antennae witli 9 nagelluni occasional!)' 

 basally white. "The eyes being clothed with short stiff pubescence " is 

 the fundamental character of the genus, and this is always easy of observa- 

 tion, i.e., if not at once seen it is probably absent. 1 consider it improlja- 

 ble that these insects are Lepidopterous parasites.

A black species with the tegulae concolorous, all the tibiae entirely red 

 and the centre of the abdomen with three red trans-fasciae. Length, 

 5-6 mm. 



Known from all the other species by its black tegulae and antennae, 

 the concolorous mandibles with their centre pale, the entirely red femora 

 and tibiae, and somewhat determinate metanotal areola and costulae. Of 

 species with black tegulae this is the only one whose female lias immacu- 

 late Hagellum ; the male is extremely like that of the next species, from 

 which both sexes are best distinguished by the immaculate red hind 

 tibiae, but it is said by Thomson to have the areola and its costulae more 

 distinct. 



North and central P2uropc, rarer than the next species; Lapland, 

 Sweden in July, France, Breslau and Prussia. It has long been known 

 as British, though it must be extremely rare with us for I have but a 

 couple of females in Dr. Capron's Surrey collection, with one captured by 

 Edward Saunders at Deal in May, 1872; and Bignell is said by l^ridg.- 

 Fitch (Entom. 1885, p. loi) to have bred it from Anisopttryx acsculan'a, 

 as the former tells us on 8th July in Devon. Of males I have captured a 

 couple about Ipswich on reeds and mountain ash in June and as early as 

 loth April, and taken the female on Heracleum flowers during early 

 August in Bentley Woods.
