regular false vein. Hind femora moderately dilated, with 
the apex slightly attenuate. Hind tibiz a little shorter than 
femora; inner lower spur more than twice as long as the 
lower outer one and about one-third longer than the inner 
upper spur; both inner spurs thick, gradually bent. The 
external genitalia as in Aolopus. 
Genotype: Gomphocerus (/pacromia) socius, Stal. 
This new genus is very easily separated from the closely 
related Afolopus, as well as from other genera of the same 
group, by the almost vertical position of the temporal 
foveole, which are, besides, not marginated behind; the 
length of the inner tibial spurs is also very characteristic.

The species is extremely variable not only in its coloration, 
but in some morphological characters as well. ‘hus, the 
hind angle of the pronotum may be either sharp or straight ; 
the lateral keels are s»metimes rather well developed even 
in the metazona, aud sometimes scarcely perceptible in the 
prozona; there are often two irregular longitudinal keels 
parallel to the median keel (mentioned by Stal, /. c. p. 343),

Aneolopus soeius (Stal). 
but in many cases there is no trace of those keels ; elytra are 
now shorter than hind femora, now distinctly longer and 
more narrow. As for coloration, St. prasinus, Walk., and 
Ep. minuscula, Walk., represent two extreme forms, which 
are connected by an uninterrupted series of intermediate 
colour-forms, and Gomphocerus socius, St., belongs to one
