dicular vein. Sp. A. indagatrix^ sp. n., ibid., Aix ; also probably Eitccela 
filicm'nis (Thoms.). 
Hexaplasta (ibid.). Malar furrow fine, facial grooves shallow ; antennae 
13- jointed, with 6-jointed distinct club, first joint of funiculus longer than 
following joints ; scutellum slightly striate, cup large, shallow, smooth and 
shining, with a round groove behind j second segment crowned with hair at 
the base j radial cell open, first section of radius slightly shorter than second. 
Spp. H. hexatorna (Hart.) and rujimntris (Gir.). 
TryUiographa (ibid.). Malar furrow fine, facial grooves broad j antennae 
in $ 12-jointed, with 8-jointed club, and first joint of funiculus somewhat 
longer than second ; in cf 15-jointed, first joint of funiculus not longer than 
second, not distinctly curved ; scutellum rugulose, with a large, rotundated, 
excavated, margined cup, which has a deep groove at its hinder margin ; 
metasternum as in preceding; second segment of abdomen crowned with 
tomentose hairs at the base ; radial cell open. Spp. : T. seutellaris, dtaphana, 
atra, moniliatay rujipes (Hart.), nigripes, antennata (Gir.), fumipemiis, octo- 
toma, albipennis, enneatoma (Thoms.). 
Diranehis (p. 360). Antennae 16-jointed, first joint of funiculus 1^ times 
as long as second, slightly bowed, the second and following joints almost of 
equal length ; scutellum rugulose, with a moderately large, ovate, margined 
cup ; sides of metasternum thickly tomentose over the hinder coxae, second 
segment of abdomen crowned with tomentose hairs at the base ; wings hairy, 
rounded at apex, hair-fringed, with the radial cell open and the first section 
of radius distinctly shorter. than the second. Only known in the S sex, 
which, as the author suggests, may possibly bo the S of Aphistophyza. Sp. 
D. copidata, sp. n., ibid., Rhine bank at Cologne. 
5. Megapelmoid^e {Anacharoidce) , The author adopts this 
name, from the typical genus Megapelmus (Hart.), as the prior 
Anacharis (Halm.) is anticipated for the well-known water-plant. 
He recharacterizes Xyalaspis and Megapelmus (Hart.), and 
Mgilips (Hal.), and describes the following new genus and 
species ; — 
Synapsis (p. 361). Maxillary palpi 5-, labial palpi 3-jointed ; antennae fili- 
form, in (S 14-jointed, the first two joints of fimiculus of equal length ; 
mesonotum not divided behind from the scutellum, smooth, with no parap- 
sidal furrows ; metanotum only indistinctly and imperfectly reticulate- 
divided ; abdomen narrow, somewhat compressed at the sides, the pedicle 
smooth, a little longer than the hind coxae ; radial cell closed, the two cubital 
cells marked by a thick spot. Sp. S. aquisyranensis, sp. n., ibid., Aix. 
Megapelmus rufiventris (Hart.) = immunis, Walk. ; Xyalaspis Icevigata 
(Hart.) = A£gilips nitidula (Halm., Cynips). 
* 6. Onychioid.®. The author recharacterizes .^5j9icera(Dahlb.), 
Onychia (Hal.), Homalaspis (Gir.). 
7. FigitoidvE. The author recharacterizes Ceroptres (Hart.), 
Lonchidia (Thoms.), Figites (Latr.), Melanips (Hal.; Ambly- 
notusy Hart., Reinh., Thoms.), (Hart.; AmphitectuSy 
Hart., Gir.; MelanipSy Gir., partim), and Melanips (Thoms.,
