new Species of Histeride. 361 
large and shallow, with very fine points intermixed, the 
lateral carine continue behind the head as an indistinct 
marginal stria, vague and faintly crenulate, there is a shallow 
antescutellar depression; the elytra, humeral and sub- 
humeral strize complete and cariniform, six dorsal complete, 
the sutural joining the fifth at the base, along the suturs is a 
row of punctures set very regularly, which at first sight look 
like an inner sutural stria, the first, second, and third strie 
are more or less cariniform, especially at their bases, the 
interstices have a lineal punctuation; the propygidium and 
pygidium are punctured somewhat similarly to the thorax, 
but are without the intermediate fine points; the prosternum 
irregularly punctate, strize cariniform between the coxe and 
anteriorly greatly widen out, and continue to join in front as a 
rim to the lobe ; the mesosternum, truncate anteriorly, trans- 
verse and narrow, strongly margined at the sides, anterior 
marginal stria scarcely visible, sparsely punctate, transverse 
stria almost straight and crenulate; the metasternum and 
first abdominal segment also sparsely punctate ; the legs and 
antenne concolorous, club of the latter paler. 
This species is more oval (not broadly oval) than S. cali- 
fornicus, Horn. The long basal joint of the antenna, the 
broad prosternum, the narrow transverse mesosternum, form 
of the legs, and general dorsal sculpture leave no doubt in 
my wind that the species is congeneric with S. parra, Mars., 
from Australia.

Phelister hilarulus, sp. n. 
Suborbicularis, convexus, niger, nitidus ; fronte plana, stria semi- 
circulari integra; pronoto lateribus distincte punctato, stria 
integra antice crenulata ; elytris striis 1-3 integris, 4 interrupta, 
5 breyi, suturali dimidiata obliqua; propygidio pygidioque 
aliquanto dense punctulatis; prosterno mesosternoque punctatis ; 
tibiis anticis spinosis. 
L. 2? mill. 
Nearly orbicular in outline, convex, black, and shining; 
the legs and antennz pitchy brown; the head with an ex- 
tremely fine punctuation, stria well marked and semicircular 
in outline (a character possessed by other species of this 
section) ; the thorax, marginal stria entire, raised at t he 
angles, feebly crenulate behind the neck ; surface very finely 
punctulate on the disk, with larger points broadly scattered 
on either side, and before the scutellum is a rugose biarcuate 
impression ; the elytra, striz 1-3 well-marked and complete,
