Geodephagous Coleoptera of Japan. 297 
thorax with posterior angles more distinctly rectangular ; 
it differs conspicuously in having four broad and deep 
elytral strite, with the fifth also tolerably well marked. 
The first and second stria3 continue deep to the apex ; the 
third is also deep as far as the very strong recurved striole, 
which it nearly touches; the fourth is of equal length to 
the third, and the fifth much abbreviated. 
T. pallescens, n. sp. 
Subdepressus, testaceo-fulvus, capite postice nigro ; 
thorace postice magis angustato, subcordato, angulis pos- 
ticis prominulis acutis ; elytris oblongo-ovatis, striis tribus 
profundis, quarta subobsoleta, 3'* ante striolam recurvam 
evanescenti.

Allied to T. bistriatus, but the elytra rather more 
ovate, and the colour pallid dingy-testaceous, with the 
crown and occiput black, and thorax sometimes inclined 
to rufous. The thorax is much narrowed behind, and the 
projecting hind angles cause the margin to be markedly 
sinuated just before them. There are three deep and 
broad stride, but the third is faint before reaching the 
recurved striole ; the fourth stria is but slightly traced. 
There is a large puncture or foveole on the fourth inter- 
stice before the middle of the elytra. 
T. sericans, n. sp. 
Subdepressus, rufo-testaceus, elytris Isete sericeo-mi- 
cantibus, capite postice nigro ; elytris post medium fascia 
fusca lateraliter late vage dilatata, tri-striatis, stria 3'* vix 
impressa uuifoveata; pedibus flavo-testaceis.

Nagasaki. 
Allied to T. fulvicollis ; but elytra more ovate, and 
with a bright silky gloss. Two strias only strongly im- 
pressed; the third faint and abbreviated, with a large 
puncture before the middle; the first stria alone reaches 
the apex, the second and third being quite obliterated 
long before the apex ; the dusky fascia is very vaguely 
defined, and is dilated irregularly on the sides. The 
thorax is quadrate, moderately narrowed behind, with the 
hind angles rectangular and not at all produced.
