impressions not well defined, the ridi^e between each and tlie 

 sharply marked lateral sulcus rather broad ; between the two 

 frontal punctures there is an elongate fovea, and between the 

 eyes a distinct puncture ; the labrum is sano-uineous. 

 Thorax only an eighth broader than long, the middle widest 

 but not markedly so, its sides rather finely margined and 

 almost regularly, yet only moderately rounded, gradually 

 and not sinuously narrowed behind, posterior angles straight 

 but not acute ; disk convex, feebly transversely striate, 

 mesial groove shortened in front, basal fossae large and broad, 

 with a carina between each and the lateral margin, base sub- 

 truncate, apex slightly incurved. Scutellum smooth. Elytra 

 oval, with broad margins ; the sutural two strife on each 

 elytron distinct and seemingly impunctate, third and fourth 

 fine, fifth and sixth nearly obsolete, being indicated only by 

 fine punctures, these four stiice are hardly perceptible near 

 the base and apex ; the third interstices are bipunctate, the 

 apical carina is well developed, and the four marginal 

 punctures near each shoulder are distinct. 



Underside glossy a^neo-fuscousj tlie sides of the ventral 

 segments broadly fulvescent. 



Differs from 0. sohrinus in having the thorax transversely 

 striate, by the presence of a central puncture between the 

 eyes. The elytral margins disappear on reaching the front 

 of the carina, in 0. sobrmus the margins are broader behind 

 and distinct almost to the extremity. In 0. nigriudus the 

 posterior tibiai are slightly flexuous, and the elytral apices 

 are narrower.

Palmerston North and Karori {Mr. G. V. Hudson). One 

 specimen. 



Oopterus frontalis, sp. n. 



Nitid, piceous ; the head, basal margins of thorax, the 

 suture and lateral margins of el} tra jjiceo-rufous ; legs, palpi, 

 and antennje testaceous. 



Head rather elongate, convex, smooth and shining, con- 

 tracted laterally behind the eyes, which, though large and 

 longitudinally oval, are but little prominent, the frontal 

 impressions are deep and elongate. The antennse reach 

 beyond the base o£ thorax, basal joint rather slender, it and 

 the second glabrous and yellow, remaining ones slightly 

 rufescent and obviously pubescent. Thorax subquadrate, 

 one-fourth broader than long, base truncate, apex incurved ; 

 its sides nearly straight and only slightly narrowed behind
