a single tubercle directed forwards. Elytra scarcely as broad as the thorax, a little 

 longer than the thorax, head and mandibles together ; the five dorsal strise are deep, 

 and not visibly punctured, the sixth is slightly punctured, and the seventh more 

 distinctly, the eighth and ninth are composed of not very deep punctures ; the dorsal 

 interstices are gently convex. Length, 6^ lin. (13 mill.) ; width, 2 lin.

Variety, immature. A Bpecimeu Las the three outer strise of the 

 elytra composed only of punctures. Length, 6f lin. 



FlGULUS PUNCTATUS, Sp. nOV. 

 Head concave above, thickly and strongly punctured, the anterior margin is 

 emarginate between the mandibles, the clypeus is almost imperceptibly bidentate ; 

 the side between the outer base of the mandible and the canthus of the eye is slightly 

 oblique and very slightly emarginate (not nearly so oblique as in the former species); 

 the canthus is narrow, with a very slightly prominent obtuse angle (nearly a rectangle) 

 in front ; vei-y gently curved, terminating posteriorly in an obtuse angle, longitudi- 

 nally canaliculate between the eye and the outer margin, which is thickened. The 

 head is broadest in a line with the back of the eyes. The mandibles are curved and 

 acuminate, with a smgle tooth in the middle on the inner side. The thorax is 

 broader than the head, rather broader than long, with a broad, strongly punctured 

 furrow in the middle, on each side of which the sui-face is sparingly and thickly pimc- 

 tured, towards the sides it is strongly and thickly punctured ; there is a distinct 

 tubercle on the anterior margin ; this margin is gently emarginate to receive the 

 head, the anterior angles are evenly rounded, the sides are sub-parallel, the posterior 

 angles are broadly rounded. The elytra are the same width as the thorax, and have 

 the five dorsal striae deep and only the fifth scarcely visibly punctured, the sixth to 

 the ninth are distinctly and strongly punctured, becoming less deep towards the 

 margins ; the dorsal interstices are scarcely convex, and are impunctate. The sides 

 of the thorax and the shoidders of the elytra are minutely crenulate. 



Length, 5 lin. ; width, 1| lin.
