of antennae testaceous, rest piceous or blackish, third and fourth 
equal. Thorax twice as broad as long, sides acutely angulate 
near base ; anterior sulcus nearly entire, very narrow ; surface 
sculptured and pubescent like the head. Seutellum trigonal, 
smooth. Elytra with deep basal depression, strongly punctate- 
striate, punctures very closely placed, interstices strongly costate 
at the sides and to a less degree on the disc. Legs testaceous • 
femora more or less piceous at apex, with a small tooth beneath. 
Prosternum twice as broad as long, punctured. 
Length 3 mm.

606. Nodostoma maculiceps, sp. n. 
Piceous or black beneath ; terminal joints of antennae black, 
basal joints flavous; head and thorax fulvous, each with a black 
spot ; elytra testaceous, sutural and lateral margins anteriorly, 
a spot below base and two behind the middle, black ; femora more 
or less spotted. 
Head dark fulvous, closely and strongly rugose and punctured ; 
clypeus rugose like the rest of the head, its anterior border slightly 
emarginate ; antennae black, slender, basal four joints flavous, 
third slightly shorter than the fourth, terminal joint elongate, 
thickened. Thorax scarcely twice as broad as long, convex, sides 
obsoletely angulate near base, gradually narrowed at apex ; surface 
very strongly rugose and punctured, sparingly clothed with short 
pubescence ; anterior sulcus faintly marked. Seutellum nearly 
black. Elytra oblong, transversely depressed below base, each 
with ten strongly raised longitudinal cost®, the interstices strongly 
punctured, the suture and an elongate spot or short stripe behind 
the middle on the fourth costa obscure piceous. Anterior femora 
strongly thickened, with a large black spot below near apex. 
Var. Elytral and femoral markings obsolete.

A very variable species in regard to size and markings, but well 
distinguished by the closely rugose head and thorax, central spot 
of latter, and the elytral costae. In well marked specimens the 
elytral spots are black, in others only fuscous or absent altogether. 
607. Nodostoma instabile, sp. n. 
$ . Testaceous. ITead strongly and closely punctured ; clypeus 
not separated from the face ; antennae entirely testaceous, second 
joint proportionately long, but slightly shorter than the first and 
third joints, terminal joints rather thickened, extending beyond 
middle of elytra. Thorax transverse, strongly narrowed in front, 
sides with a blunt angle near base, anterior sulcus entire : surface 
closely rugosely punctured, interstices sparingly pubescent. Elytra 
rather long, with distinct depression below base ; puncturation
