AGRILUS VINCTUS, new species 



Male.— SmaW, rather slender, rather strongly flattened, moderately 

 shining, and uniformly dark olivaceous-green above ; beneath brown- 

 ish black, with a vague cupreous or aeneous tinge. 



Head with the front wide, feebly convex, slightly wider at top than 

 at bottom, lateral margins feebly, obliquely converging from top 

 to bottom, and broadly, feebly, longitudinally depressed from epis- 

 toma to occiput; surface coarsely but not very deeply, irregularly 

 rugose, coarsely, sparsely punctate between the rugae, nearly gla- 

 brous; epistoma slightly transverse between the antennae, not ele- 

 vated, but broadly, deeply, arcuately emarginate in front; antenna 

 long, serrate from the fifth joint, the outer joints strongly triangular 

 and slightly longer than wide; eyes rather small, oblong, equally 

 rounded above and beneath. 



Pronotum one fourth wider than long, slightly narrower at base 

 than at apex, widest in front of middle; sides arcuately rounded 

 anteriorly, strongly, obliquely narrowed posteriorly to the posterior 

 angles, which are rectangular; when viewed from the side the mar- 

 ginal and submarginal carinae feebly sinuate, widely separated an- 

 teriorly but joined near the base; anterior margin strongly sinuate, 

 the median lobe strongly produced and broadly rounded; base 

 vaguely, arcuately emarginate at middle of each elytron, with the 

 median lobe feebly produced and broadly rounded; disk sliglitly 

 convex, feebly, broadly depressed on each side along lateral margin, 

 with a vague, broad, longitudinal, median depression, and with feebly 

 distinct, slightly sinuate prehumeral carinae, which extend forward 

 to middle of pronotum ; surface densely, deeply, transversely rugose, 

 coarsely, densely punctate between the rugae, nearly glabrous. Scu- 

 tellum not transversely carinate, but the surface depressed and 

 feebly reticulate. 



Elytra slightly wider than pronotum at base, subequal in width 

 at base and behind middle ; sides parallel for a short distance behind 

 base, broadly, arcuately constricted in front of middle, broadly, arcu- 

 ately expanded behind middle, then obliquely narrowed to the tips, 

 which are separately rather broadly rounded and feebly serrulate; 

 sides of abdomen not exposed above; disk feebly flattened along 

 sutural margins, which are strongly elevated, and with broad, rather 

 shallow, basal depressions ; surface densely, finely imbricate-punctate, 

 somewhat scabrous, sparsely clothed with very short, inconspicuous 

 hairs. 



Abdomen beneath feebly, finely marked with transverse, crenulate 

 lines, finely, sparsely punctate, sparsely clothed with short, recum- 

 bent, whitish hairs ; first segment narrowly, longitudinally depressed 

 at middle, the depression densely clothed with long, erect, white 

 hairs, the suture between first and second segments not indicated at
