new Species of Histeride. 181 
Fachycrerus striaticeps, sp. 0. 
Oblongo-ovalis, supra convexus, niger, nitidus; capite antice ex- 
cavato, stria late sinuata; pronoto angulis anticis subfoveolatis ; 
elytris striis 1-3 subhumeralique integris, 4 basi abbreviata, 5 
apicali, suturali integra. 
L. 33 mill. 
Oblong-oval, convex above, black, shining; the head 
deeply excavated in front and on theepistoma; frontal stria very 
fine and widely sinuous, the sinuosity bending towards the 
neck, near the base of the head between the eyes is a second 
well-marked transverse stria, surface feebly and irregularly 
punctured, some points being small and others larger; the 
thorax, anterior angles subfoveolate and somewhat closely 
punctured, and the punctures on the disk are rather sparse 
and clearly composed of small and larger points, the lateral 
stria is sinuous and continued behind the neck; the elytra, 
striz 1-3 and inner subhumeral complete, 4 rather fine and 
shortened before the base, 5 apical and nearly half the length 
of the fourth, sutural complete; the propygidium punctate 
(very similar to P. cyanescens, Er.) ; the pygidium with the 
punctures fine and more scattered; the prosternum has a micro- 
scopic strigose sculpture and a few punctures on the anterior 
lobe, the stria start from the base and gradually meet ante- 
riorly, there are a few punctures on the keel ; the mesosternum, 
stria very fine and does not quite meet in front; the lateral 
strie of the metasternum do not widen out like those of 
P. cyanescens ; the anterior tibia has three rather large teeth 
coequal in size and one small at the base; the legs obscure 
reddish brown. 
The species is rather more oblong in outline than P. eyan- 
escens, Kr., and P. congonis, Sch. 
Note.——In P. diversicollis, Sch., and others, the frontal 
stria is carried in a semicircular form at the back of the head 
behind the eyes. In P. striaticeps the stria is straight and 
detached and lies between the eyes.
