DOLEROTARSA, n. gen. 
This genus is allied to Alogistotarsa, the buccal organs are the 
same, and also the general appearance; the clypeus, however, is 
deeply incised laterally and more constricted there at a short 
distance from the apex, the anterior margin being quite narrow, 
reflexed, arcuately emarginate, not angular in the centre and with 
the angles acute instead of a keel, there is a frontal suture; the 
anterior tibia are uni-dentate, the non-apical tooth being hardly 
distinct and represented by a slight sinuation only, and there is no 
inner apical spur, the tarsal joints are long, straight inwardly, 
rounded outwardly towards the apex, except the apical one, and 
with one or two slender bristles set past the median part on the 
outer side only, not near the apex; in the male the outer claw of the 
anterior tibize is normal, and the lower tooth wider and stronger than 
the upper, the inner is broadly dilated at the base and bent at right 
angles somewhat in the manner of Camenta, and slightly bifid at the 
tip, the other claws are strongly divergent, and equally cleft under- 
neath ; abdomen compressed laterally; antennz 10-jointed, club of 
male as long as the head. 
This genus is a form of transition between Id@serica, which has a 
moderately constricted clypeus, and those in which the clypeus is 
strongly constricted, and tri-dentate in front. In Jd@serica the 
anterior tarsal joints are not unlike those of Dolerotarsa, but they 
are not fused, and the shape of the anterior claws of the male is 
different. 
DoOLEROTARSA EMENDATRIX, Nl. Spec. 
Testaceous-red, with the elytra testaceous yellow, antenne flavous; 
head deeply and slightly roughly punctate from the apex of the 
clypeus to the basal part; clypeus not tri-dentate in front, strongly 
constricted laterally at a short distance from the apex the margin of 
which is slightly arcuate with the outer angles sharp, the frontal 
suture is only moderately deep and the genz strong and oblique; 
antennal club of male nearly as long as the head; prothorax broader 
at the base than at the apex, hardly sinuate laterally behind, closely 
punctate ; scutellum elongate, ogival; elytra elongated, sub-parallel, 
barely covering the anterior part of the propygidium, plainly striate 
with the intervals raised and tectiform in the dorsal part, very 
numerously punctate, glabrous; abdominal segments with a double 
row of punctures ; cox as deeply punctate as the metasternum, and 
plainly concave; pectus glabrous; anterior tibize with only the 
apical tooth well defined, the second one being reduced to a mere
