ZOOLOGICAL LITEllATUUE. 
with two abbreviated furrows in front ; scutellum rugose, with a more or 
less blunt denticle on the lateral margin, the cup very large, strongly mar- 
gined, and with a large groove on the hinder margin j metasternum and abdo- 
men as in preceding genus 3 wings entirely bare, with no trace of hair- 
fringe, the radial cell closed. Spp. P, hoyenii and maculata (Hartig). 
Hypolethria (ibid.). Malar furrow &c. as in preceding j antenna3 in S 
IS-jointedj the joints of funiculus elongato-cylindrical, the first joint not 
emarginate, somewhat smaller than the second j in $ 13-jointed, with no 
defined club ; mesonotum as in the two next genera, with no furrows j scu- 
tellum finely rugulose, its cup very large, elevated clear of the point of scu- 
tellum, and with a groove at the hinder margin j metasternum and second 
segment of abdomen as in preceding, the abdomen exceedingly strongly com- 
pressed at the sides, with a very narrow dorsal surface j radial cell closed. 
Sp. II. melanoptera (Hart.). 
Aylaotoma (ibid.). Malar furrow finej antenna) in $ 13-jointed, with 
8-jointed club, the first three joints of funiculus very elongate, and thinner 
than the following, with the first longer than the second joint j in the cJ 
15-joiuted, with the first joint of funiculus exceedingly elongate, almost as 
long as the three following together, scarcely curved j scutellum with a 
small, ovate, margined cup j metasternum and second segment as in preceding- 
genus J wings hairy, rounded at apex, with a fringe of hairs, the radial cell 
closed, the second section of the radius entirely straight. Sp. A. codrina 
(Hart.), of which the author has found $ at Aix. Distinguished from the 
allied species of llhoptromeru by the very elongate joints of funiculus, and 
by the almost filiform tarsi. 
Ganaspis (p. 355). Malar furrow very slight j facial grooves not especially 
large J antennae in $ 13-jointed, almost filiform, with the 6-7 last joints 
only slightly thicker than the preceding; in S 15-jointed, the first joint 
of funiculus only slightly longer than the second, and distinctly bowed; 
scutellar cup not deep, immarginate, entirely smooth, and with a round 
groove at the hinder margin ; sides of metasternum bare and smooth ; second 
segment of abdomen covered with hair at the base ; wings as in preceding 
genus, the radial cell closed at the fore margin, and at its inner angle, with 
a small oblique continuation near the first section of the radius. Sp. G. 
mundatay sp. n.,.ibid., Aix. 
Chrestosema (ibid.). Malar furrow distinct, entirely smooth beneath, 
vertex elevated, ocelli moderately large; antennae in $ 13-jointed, with no 
defined club, the first joint somewhat longer than the second ; in 6“ 15-jointcd 
with the first joint of funiculus almost as long as the two following joints, 
all the rest of equal length, cylindrical, nearly twice as long as broad ; meso- 
notum with two fine middle furrows, abbreviated behind, and two very broad 
and flat lateral impressions, abbreviated in front ; scutellum finely rugulose, 
its cup large, elliptic, almost twice as long as broad, finely margined, with a 
round groove at the hinder margin ; metasternum and second segment as in 
Aylaotoma ; wings hairy, rounded at apex, with a hair fringe, and the radial 
cell closed at fore margin. Sp. C. erythropa, sp. n., p. 860, Aix. 
Pdichacra (p. 356). Malar ridge slight; face beneath with broad, long 
impressions; antennie in O' 15-, in $ 13-jointed, with no distinctly defined 
club ; mesonotum (as in the next ten genera) with no parapsidal furrows ; 
scutellum rugulose, with its sides strongly margined and apex dentate, and
