328 Mr. H. W. Bates's descriptions 
colorous suture and apex of the elytra. The anterior 
angles of the thorax are distant from the sides of the neck, 
and the sides are gradually and not very much narrowed 
and rounded to the base. The third elytral interstice has 
one puncture, much after the middle, and near the second 
stria.

medium modice angustato, angulis posticis rotundatis,

Kiu-Kiang. 
Similar in form to Br. harpalinns (Dej.), except that 
the head is much broader and more obtuse (like Tachy- 
celhis grandiceps'), and the thorax much broader in pro- 
portion to the length, and more narrowed fr'om the middle 
to the base. The terminal joint of the palpi is thicker, 
but the apex is attenuated to a point. The first ventral 
segment in the $ has no fovea. The thorax is always very 
dark blood-red ; the legs rather lighter and more piceous. 
Trigonotoma chalceola, n. sp. 
Oblonga, convexa, nigro-polita, el}i;ris a?neis, palpis 
testaceo-rufis ; labro angusto, medio fortiter rotundato- 
emarginato ; thorace transverso, rotundato, postice magis 
angustato, angulis posticis rotundatis, basi toto et sulco 
intra margincm lateralem grosse punctatis ; elytris breviter 
oblongis, striis fortiter impressis et punctatis; episternis et 
abdominis lateribus pauciter grosse punctatis; scgmeutis 
ventralibus transversim unisulcatis.

Hong Kong. (From Herr Mess). 
The smallest described species of the genus ; distin- 
guished further by its colour — glossy black, with dark 
teneous elytra. The labial palpi are securiform, broader 
in the $ ; the maxillary pal])i have in both sexes the inner 
side of the terminal joint dilated and rounded, and the 
apex trimcated.
