new Species of Histeride. 345 
punctured; the mesosternum is widely and feebly emar- 
ginate, stria complete, but not easy to see behind the emar- 
gination, as the sternum is depressed at that part, at the sides 
it is strong and straight; the metasternum, laterally bistriate, 
striz oblique and parallel to each other; the anterior tibiz 
are 4-dentate. 
This species also belongs to Cylist‘x, and in one of its 
characters, namely the proximity of the metasternal stria, it 
resembles C. cylindrica, Payk., more than C. astatica. 
Hab. Siam (Renong). One example. 
Pachycrerus violaceipennis, Lew., 1891, 
=P. ritseme, Mars. 
I find now that I was in error in regard to this species. I 
was misled by Marseul’s description of the frontal strie. It 
seems to me that there are two striz, but Marseul calls one a 
suture: perhaps his example was somewhat abraded. 
Psiloscelis limatulus, sp. n. 
Oblongo-ovalis, niger, nitidus, supra punctulatus ; fronte foveolata ; 
elytris striis integris, 5* suturalique antice conjunctis. 
L, 44 mill. 
Oval-oblong, rather convex, black, shining; finely and some- 
what densely punctured above; the forehead longitudinally 
foveolate, stria complete, straight in front, angulate behind 
the mandibles ; the thorax with four feeble impressions, two 
on each side, two fine marginal strie, one of which continues 
behind the head, and well within the margin is an internal 
stria very slightly abbreviated at both ends, leaving a wide 
interstice in front, which gradually narrows towards the pos- 
terior angle; the elytra, striz 1-4 complete, fifth and sutural 
also complete and joined at the base; the propygidium and 
pygidium are densely punctured, with some very fine points 
between the larger ones; the prosternum, keel narrow in 
front, widening out triangularly at the base, margined late- 
rally with a fine clearly marked stria; the mesosternum is 
truncate anteriorly, with a fine marginal stria; the sternal 
plates and first segment of the abdomen are more finely punc- 
tured than the upper surface; the anterior tibia are 6—7- 
dentate. 
This species is smaller than P. Castelnaud’, Mars., and 
differs in three essential points, viz. the forehead has a deep 
fovea, the thorax has an internal lateral stria, and the fifth 
and sutural elytral striz join at the base. 
Hab. Assam (Patkai Mountains). One example.
