C. hartigii, sp. n., ibid. (There is already a species named hartigii by the 
Recorder, Ent. Mo. Mag. 1807, vol. iv. p. 101, in Andricus, the next genus to 
CaUirhytis.) 
Dnjophanta (ibid.). Maxillary palpi 5-, labial palpi 3-jointed, as in the 
five next genera; antennre 13-14-join ted, coarsely pubescent, first joint of 
funiculus longer than second ; mesonotum punctured, with depressed hairs, 
straightly truncate behind, parapsidal furrows continuous ; scutellum with- 
out distinct grooves at base ; legs with coarse standing-out hairs ; abdomen 
at the apex with scattered hairs (not thickly crowded, depressed and silky, 
as in Cgnips) ; radial coll very elongate, open at fore margin, with the second 
cubital cell at its base. Sp. D.folii (L.). 
Ajdiilothrix (p. 336). Differs from Dryophanta in its antennje and legs 
not having coarse hairs. Sp. A. corticis (L.). 
Eiihothrus (ibid.). Face aciculate-punctured ; antennas in <? 14-^ in 5 
13-jointed, filiform, first joint of funiculus shorter than second ; mesonotum 
somewhat rugulose, parapsidal furrows continuous, sides of mesosternum 
nciculate ; scutellum with two large basal grooves, reaching the middle, but 
distinctly separate ; radial cell elongate, open at the fore margin, base, and 
apex ; the basal and lateral sections of the radius almost entirely straight ; 
second cubital cell almost at the base of the radial, imperfectly closed by a 
spurious vein ; second section without longitudinal furrows at the base. Sp. 
E. scahioscB (Gir.), but which has already been given by the author at p. 334 
as the type of his genus Iscolus, a mistake not noticed in the list of errata. 
Liposthenes (ibid.). Antennae in cf 14-, in $ 13-jointed, filiform, first 
and second joirits of funiculus equal in length, the first not bowed in the cT ; 
mesonotum coriaceous, parapsidal furrows continuous ; scutellum with two 
distinct basal grooves not reaching the middle ; radial cell elongate, open at 
fore margin, base, and apex ; the basal section of the radius arched, much 
thickened, the lateral section very fine, curved at the base ; second cubital cel 
wanting; second segment with no longitudinal furrows. Sp. X. glechomce 
(Hart.). 
PericUstus (p. 337). Face aciculate ; antennae in cf 14-, in $ 12-13- 
jointed, first and second joints of funiculus equal in length ; mesonotum 
coriaceous, sides of mesosternum aciculate ; scutellum with two distinct 
grooves at the base ; second segment of abdomen very large, with no longi- 
tudinal furrow at base, third segment very small in $ ; radial cell closed at 
fore margin, broader than long, with second cubital cell at its base. Sp. P. 
canince (Hart.). 
Xestophanes (ibid.). Antennae filiform, in 14-, in $ 13-jointed, first 
joint of funiculus equal to or somewhat longer than the second, curved in 
the S ) mesonotum entirely smooth, parapsidal furrows continuous ; scutellum 
with two large and distinct basal grooves; radial cell longer than broad, open 
at fore margin, second cubital cell widely removed from its base ; second 
segment of abdomen with no longitudinal basal furrows. Sp. X. potcntillcB' 
(De Vill.). 
Sapholytus (ibid.). Maxillary palpi 6-, labial palpi 2-jointed ; antennae 
filiform, in cf 15-j in 2 13-14-jointed, first joint of funiculus longer than 
second, curved in cf ; face aciculate ; mesonotum rugulose, parapsidal fur-
