This species is closely allied to elongatus Herbst, but that species 

 is more elongate and slender, the head is narrower in front, with the 

 sides arciiately expanded at vertex, and not depresssed on the front, 

 prothorax with the sides more strongly narrowed, and the disk more 

 deeply depressed, pygidium not longitudinally carinate, prosternal 

 lobe not as deeply emarginate in front, and not as strongly declivous, 

 and the posterior tarsi nearly as long as the tibiae. 



AGRILUS PRINADAl, new species 



Female. — Form moderately large, more slender than cocJcerelU 

 Fisher, and subopaque; above dark aeneous, with a more or less 

 brownish and bluish tinge, the head slightly more aureous in front, 

 and the pronotum obsoletely cupreous on disk; beneath, aeneous, 

 with a distinct bluish and blackish-brown reflection, and more 

 shining than above. 



Head rather narrow and nearly flat in front, with the sides nearly 

 parallel (only feebly arcuately expanded at vertex), feebly longi- 

 tudinally grooved from vertex to near the epistoma, the groove 

 more deeply impressed on the vertex, and terminating in a broad 

 shallow depression on the front; surface coarsely, irregularly punc- 

 tate, and coarsely rugose, the rugae irregular, and more or less trans- 

 verse on the front, but becoming longitudinal on the occiput, and 

 sparsely clothed with short semierect whitish hairs; epistoma about 

 as wide between the antennae as the diameter of the antennal cavi- 

 ties, and broadly, but not deeply, arcuately emarginate in front; 

 antennae extending to about middle of pronotum, and serrate from 

 the fourth joint. 



Pronotum about one and three-fourths times as wide as long, 

 slightly narrower at base than apex, and widest near apical angles; 

 sides feebly obliquely narrowed from anterior margin to posterior 

 angles, which are rectangular; when viewed from the side the upper 

 margin is sharply defined and strongly sinuate, and the lower mar- 

 gin distinct, arcuately expanded from the apical angles to the basal 

 third where it is connected to the upper margin; anterior margin 

 arcuately emarginate, and with a broadly rounded medina lobe; 

 base deeply angularly emarginate at the elytral lobes, and nearly 

 transversely truncate in front of scutellum; surface moderately con- 

 vex, with a broad obsolete longitudinal depression on middle of disk, 

 and with a broad, deep depression on each side along lateral mar- 

 gins, the lateral carina distinct, strongly elevated, straight, and ex- 

 tending from base near posterior angles to basal third, and widely 

 separated from lat(>ral margin, coarsely and densely rugose, the 

 rugae more or less transverse on the disk, coarsely, densely punctate 

 between the rugae, and sparsely clothed with short inconspicuous
