and there is a slight sinuosity in the margin on each side ; 

 the frontal carina is nearly straight, but has its middle and 

 angles very slightly raised. The thorax has the median line 

 strongly marked and reaching beyond the middle ; the 

 impressions at the base are transverse and not conspicuous ; 

 the punctuation is very tine and moderately close on the disk, 

 much stronger at the sides ; the tine ridge at the anterior 

 border is slightly oblique on each side, with a small, rather 

 acute tubercle in the middle. The posterior tarsi have the 

 basal joint scarcely twice as long as broad, strongly emar- 

 ginate at the apex ; the second joint narrow, a little thickened 

 before the middle, about half the length of the basal joint.

This is one of the more elongate species and only slightly 

 depressed. The head is black in front, partly coppery and 

 partly green posteriorly ; the frontal ridge is very gently 

 curved, obscurely punctured posteriorly ; the two anterior 

 teeth are separated by a nearly equilateral- triangular space, 

 and their outer edge forms with the margin an angle a little 

 less than a right angle. The thorax has its sides parallel at 

 the middle ; the front portion is black, the black extending 

 more at the sides ; the median line is strongly marked, 

 extending beyond the middle ; the basal impressions are very 

 small and inconspicuous ; the anterior ridge is somewhat 

 oblique on each side, obtusely angulated forwards in the 

 middle, but with scarcely any tubercle. The elytra are a 

 tritle longer than broad, obscure coppery, with slight green 

 reflexions ; the strife deep, not very distinctly punctured, the 

 interstices moderately convex and almost smooth. The 

 posterior legs are short and thick ; the basal joint of the 

 posterior tarsi about one third longer than broad j the second 

 joint scarcely shorter than the first, but much narrower, sub-
