very stout, spined. Femora sulcate below. Hind femora much 
dilated at the base, not longer than the body, Foramina of fore 
tibie quite rudimentary (notably posteriorly), terete above, be- 
low with five spines on each margin. Hind tibize above with 
two long terminal spurs inside, and with four short ones exter- 
nally, also below one on each side. Abdomen stout, cylindrical, 
segments not granulose. Cerci of female very slender, shorter 
than supra-anal lamina. Subanal valves elongate-oval.  Ovi- 
positor slender, gradually incurved, acuminate from below, apex 
very acute. Subgenital lamina broad, nearly semicircular. 
The large insect, for whose reception the genus is established, 
differs too much from all others to admit of its inclusion in 
Trihoplophora, its nearest ally, as will be seen by inspecting the 
synoptical key.

C. E. Driffield, to whose memory it is dedicated. Collection S.A.

The rudimentary foramina render this species very interesting, 
connecting those species without them directly with the others 
which possess them in a perfect form. On the anterior side 
they are tolerably distinct, although small, and denoted by 
brownish shading, but on the opposite side are only indicated by 
a minute impression. 
PACHYPODAGRUS,* gem. nov. 
Head distinctly wider than pronotum, oval. Occiput elevated. 
Vertex declined. Fastigium rounded, slightly sulcate, three to 
four times wider than the first antennal joint. Medial ocelliform 
spot small, circular, not very distinct, lateral ones inconspicuous 
or absent. Antenne very slender, not much longer than the 
body. Eyes large, elliptical, depressed. Pronotum cylindrical, 
sulci deep, lobes high, inferior margin semicircular. Elytra ab- 
* Thick-gouty.
