and on some Types of Oriental Carabidae. 177 
description of D. laevigata Bates (Ann. Mus. Civ. Gen. 1892, 
326) except in one particular. Comparing his new species 
with D. polita F. (as then identified), he says, “ labro et 
epistomate similiter emarginato,’ whereas in the Indo- 
Chinese specimens the emargination of the clypeus is very 
shallow. Mr. Fea took one example only of D. laevigata 
at Kaw Kareet, in Tenasserim, and until I have seen this 
type, I do not like to describe the species as new. 
38. Anisodactylus ? (p. 268). I have recently 
described this species (Ann. Soc. Ent. Belg. 1920, 109) 
under the name of Gnathaphanus festivus. 
45. Platymetopus laetulus Bates (p. 270) = Dvioryche 
amoena Dej. The species is not compared with any other. 
Bates knew Dejean’s species, and indeed mentions it a few 
lines further down, so that I am at a loss to account for 
the introduction of this superfluous name. 
46. Platymetopus indochinensis Bates (p. 270). This 
species, like the last, belongs to the genus Dioryche. Bates 
complained of the inadequacy of Walker's descriptions, 
but here he has almost eclipsed Walker. The description 
is contained in two lines, and gives the impression that the 
species is very much like D. amoena Dej., differing in the 
colour of the first antennal joint and the obtuse hind angles 
of the prothorax. 
It is a duller insect than D. amoena, cupreous without 
any greenish tinge; prothorax with smaller and deeper 
basal foveae, the sides not flattened out near hind angles, 
surface more (though sparsely) punctate, the fine basal 
puncturation confined to the foveae and the space between 
them, whereas in amoena it extends to the sides, leaving 
the middle of base with comparatively few punctures; 
elytra shorter and wider, the striae no deeper at apex 
than on disk, scutellary striole short, intervals rather flatter, 
1 and 2 distinctly narrower than the others, punctures 
on 3, 5, and 7 much larger (though smaller on 7 than on 
3 and 5), but fewer in number, minute puncturation 
identical. 
54. Anoplogenius renitens Bates (p. 272). The specimen 
so named by Bates is another example of 52, Anoplogenius 
microgonus Bates, but A. renitens does occur in Indo-China. 
58. Acupalpus ovatulus Bates (p. 273). Bates does not 
discuss the generic characters. The species has not the 
facies of Acupalpus, and the hind tarsi have a shallow groove 
on the outer side, a character foreign to that genus. On
