1937 ] New Buprestid Beetles 
of the elytra; apex black; the last two segments of the 
abdomen blackish. 
Head moderately large, with a feeble tranverse depression 
between the eyes; occiput finely striate, finely and sparsely 
punctate ; the part of the front between the eyes wider than 
long, its sides converging toward the vertex ; epistoma not 
distinctly separated from the front, slightly emarginate. 
Antennal cavities wide, triangular, with a little oblique 
carina above. Antennae reaching nearly to the middle of 
the length of the pronotum, serrate from the fourth joint, the 
first joint rather long, the second subglobular, the third 
nearly twice and a half as long as the second and equal to 
the fourth. 
Pronotum widest at base, nearly once and a fifth as broad 
at base as at apex, and once and a half as wide as long ; the 
anterior margin nearly transversely truncate, with a swollen 
margin, latter feebly obliterated at middle; the sides feebly 
arcuate, sinuate before the posterior angles, which are acute ; 
the marginal carina arcuate, interrupted at the anterior 
quarter; the prothoracic episterna nearly smooth; the base 
widely and somewhat deeply bisinuate. Disk feebly and 
sparsely punctate, more strongly and rugosely at the sides ; 
on each side of the median line, not far from the base, a very 
deep impression the bottom of which is crossed by an oblique 
stria inclined outward and forward at an angle of 45°. 
Scutellum small, transverse, nearly cordiform. 
Elytra once and a fifth wider than pronotum, long, sinuate 
at sides from shoulders to middle, and arcuately attenuate 
from middle to apex; strongly tridentate at tips, the pos- 
terior half strongly serrate; surface punctato-striate, the 
striae stronger on the sides, the intervals flat, equal, and 
obsoletely punctate. Punctures of the striae of the sides 
anteriorly transverse and forming some wrinkles. 
Anterior margin of the prosternum slightly emarginate, 
finely margined; prosternal process smooth, with swollen 
margin. Beneath, aciculately punctate, the last abdominal 
segment tridentate at apex, with a little denticle on each side. 
(The in the genus Nosotrinchus generally have the last 
abdominal segment emarginate between two spines, among 
the $9 it is bi-emarginate, with three spines.) Tarsi half as 
long as the tibiae ; claws short and rather strong.
