Hiogo ; one example. 
Agrees with Dolichus in facies and in the slender 
cylindrical terminal joints of the palpi ; but differs in the 
anterior tarsi (as well as the others) being deeply sulcated 
on each side. The head is rather more slender and the 
eyes less prominent. The thorax is wholly impunctate 
and the hind angles are distinct although obtuse ; the 
lateral edges are not rufous. The elytra are not sinuate 
at their apices and the strife are simple ; their sm-facc is 
not so opake, but has a silky gloss.

lariter rotundato ; elytris oblongo-ovatis, fortiter striatis.

Nagasaki ; also at Foochow, China. 
Closely resembling Crepidactyla nitida, but differing in 
the generic character of labial palpi not securiform. The 
head is small. The thorax large and ovate, Avith sides 
regularly rounded, so that the greatest Avidtli is in the 
middle; the anterior angles are distinct, but the hind 
angles are rounded off; the reflexed lateral margins are 
rufo-piceous, the basal fovete, like the rest of the surface, 
impunctate. The sides of the middle and posterior tarsi 
are grooved; the claws have 4 — 5 fine denticulations. 
The labial palpi in both sexes are only slightly dilated 
towards the apex and truncated ; this is the only character 
I can find distinguishing the genus from Crepidactyla and 
Ta.phria. 
Pristodactyla dulciyrada, n. sp. 
Elongata, gracilis, parum convexa,nigro-picea; antennis, 
palpis, pedibus, margineque thoracis piceo-fulvis ; thorace 
quadrato, lateribus paululum regulariter arcuatis, angulis 
posticis obtusissimis, supra impuuctato ; elytris apice sin- 
gidatim acute rotundatis, supra fortiter striatis, nitidis, 
interstitio 3io bipunctato ; tarsis intermediis et posticis 
utrinque sulcatis.
