groups of which the one is remote from the apex, the other is very 
near the base, the distance between the two being larger than the 
distance from the apex, apical spurs very small, both somewhat 
longer than the strongly abbreviated first tarsal joint; hind coxe 
with distinct punctures, the bristles near the outer margin here 
rudimentary, the sternum, especially in the middle anteriorly convex 
and with a weak impression on the smooth part; anterior tibiz 
narrow in both sexes, the first two teeth remote, the third rudi- 
mentary; joints 3-7 of antenna moniliform, small but distinct, 
club testaceous yellow, fairly strong, somewhat curved and some- 
what shorter than the pedicel ; the brush-like clothing of the mentum 
consists of pale-yellow laminz between which some hairs are pro- 
jecting. This not very striking but very peculiar species reminds 
one of the smaller Camenta species, which differ, however, by their 
short hind coxe.”’ 
ALLOKOTARSA, n. gen., 
Plate XLVI., fig. 4; figs. 15, 15a. 
Buccal organs of Serica; clypeus suddenly narrowed laterally, 
with the anterior margin tri-dentate, only half as wide as the head 
in the frontal part, and having a median transverse keel running 
parallel to the arcuate, very shallow frontal suture, gene long; 
antenne 10-jointed, third shorter than fourth and fifth, these 
three joints seemingly partially fused together, sixth and seventh 
very short, compressed, club 3-jointed, very little shorter than the 
whole pedicel in the male; prothorax short, sparingly setulose 
laterally ; scutellum acuminate; elytra nearly cylindrical, pygidium 
convex, triangular; abdomen plainly compressed somewhat in the 
manner of some Heterochelus of the Sub-family Hopliine; hind 
margin of coxe arcuate, covering the greatest part of the third 
segment; anterior tibiz tri-dentate outwardly, the basal tooth, how- 
ever, is very small, the anterior tarsi are short, the intermediate and 
posterior long, in the male they are abnormally developed into sub- 
triangular lobes decreasing in width from the basal to the apical joints, 
and with the three basal wider or as wide as the tibia, the claws 
are almost filiform, cleft, however, at the apex, the outer one is twice 
as long as the inner; the intermediate and posterior tarsi and claws 
are normally shaped as in the female; the spurs of the hind tibie 
are slightly longer than the basal joint which is one-third shorter 
than the second; in the male the inner spur of the anterior tibiz 
has disappeared, but it is strongly developed in the female.
