Mr. R. C. L. Perkins on 
Occipital margin not produced on each side beneath the 
head into a prominent spine. 
Small species with entirely black abdomen; the front tibiae 
either simple or Jaminately dilated, the front femora 
never armed with a spine beneath at about the basal 
third of their length. Recurrent nervure rarely received 
far beyond the middle of the lower side of the cubital 
cell. 
. Seventh dorsal abdominal segment with only a fine and 
feeble or indefinite puncturation not greatly different from 
that of the preceding. 
Mesopectus simple, not tuberculate or spinose on each side. 
Front legs with the tibiae and first two tarsal joints con- 
spicuously dilated, the front femora suddenly widened 
from the base, so as to form a distinct angle beneath;

. Middle tibiae much thickened, elongate-triangular, only 
with a few short apical or subapical spines,* the true 
calear usually wanting; hind tibiae much swollen; 
mesonotum not shining, but with extraordinarily minute 
puncturation ; superorbital foveae short, generally puncti- 
form. Ablepharipus gen. nov., A. podagricus, V.d. Lind. 
Seventh dorsal segment with a peculiar sculpture, at least 
on its apical portion (the punctures being large and close, 
though generally shallow) or quite different from that 
of the preceding. 
. Mesopectus on each side with a distinct minute spine or 
tubercle. 
. Front tibiae very greatly laminately dilated. 
Crossocerus, Lep., C'. palmarius, Schr. 
. Front tibiae not dilated, the basal joint of front tarsi 
sometimes dilated. . . . . (Stenocrabro, Ashm.). 
. Front tarsi with the basal joint conspicuously dilated, 
C. palmipes, L. 
. Front tarsi not evidently dilated. 
* T have mentioned this character, in spite of its inconstancy, on 
account of the interest of its variability.
