4. Astatus radialts, n. sp. 
$ . Niger; mandibularuni basibus, abdoniine toto, parte femoruni, 
tibiis tarsis que rufis ; antennarmu articulo tertio secundo plus 
quam duplo longiore; eapite et thorace griseo hirtulis, crebre 
punctatis; alis subfumatis, apicibus harum valde infuscatis, cellula 
radiali brevissima, latitudine sua vix duplo longiore, apice abrupte 
truncate, cellula tertia submarginali angustissima; ceteris ut in 
boope. 
5. Easily distinguished from hoops or minor by the red legs, and 
from rufipes by the short radial cell, as well as by the rather 
unusually dense grey pubescence of the head and thorax. The 
dark band of the wings also gives it an unusual appearance, this 
being more pronounced than in the other species and not quite 
reaching to the apex of the wing. The very narrow third sub- 
marginal cell is another characteristic, but this varies slightly in my 
examples. In the short radial cell the species approaches costae, 
but of that species (which I do not know) Kohl says that the wings 
are “ wasserhell,” and my specimens seem [too (?)] large for that 
species, being 7^ mm. in length. The sculpture of the propodeum 
is rather finer than in 6oops and minor. 
Long. 8 mm. 
$ (?). I have a single male, caught at Le Tarf, on the 
same day and on the same flower {Foenicitlum vulgare) as 
the female, which probably belongs to the same species. 
It has the radial cell shorter and more truncate than iti 
hoo 2 )S, and the third submargiual with a short nerve 
emitted from about its centre (this is identical in both 
wings, but may not be a constant character). The 
antennae have the intermediate joints simple, not sinuate 
as in hoo 2 )s, etc. It is, however, larger than one would 
have expected the ^ of this species to be, viz. 10 mm. 
But the species of Astahis are very variable in this 
respect. 
[A $ and 5 ^ $ answering to this description are placed 
together (unnamed) in Coll. Saunders. Two are from 
Bone, the rest from Le Tarf, 24. and 26. vii, 96. A. E. E.] 
5. TaCHYTES BISKREx\SIS, n. sp.

maxima parte rufo-testaceis; eapite et thorace pilis argenteis dense 
vestitis ; alis hyalinis ; abdomine toto rufo-testaceo ; 9 segmentis
