OF NEW ZEALAND. 765 



Group— SYNCHITID^. 



Ablabus (p. 183). 



1353- A. brevis, n-s. Oblong, rather broad and convex; rufo- 

 piceous, clothed with pale yellow, almost griseous, scale-like setce ; 

 legs and antenna red ; underside pitchy, covered with granules and 

 fine yellow hairs. 



Head granulated. Prothorax broader than long, transversely 

 convex, somewhat uneven, but without conspicuous tubercles or de- 

 pressions, granulated ; sides explanate, four-lobed, the front lobe 

 largest, the basal small and distant from the elytra. Elytra oblong, 

 apices obliquely rounded, sides more or less dentated ; disc some- 

 what plane, rather uneven, apparently punctate-striate, with a 

 distinct compressed elevation on each side of the scutellum, two 

 rounded ones behind, and others nearer the sides. Legs finely 

 hirsute. 



The insect has been denuded of the scale-like greyish covering. 

 When just found it seems rougher, the elytra, for example, appearing 

 to have four rows of tubercles, four in each, and the thorax with a 

 medial groove and three basal depressions. 



Comes near A. ornatus, but that species may be distinguished at 

 a glance by the large black triangular space on the side of each 

 elytron. 



Length, 1^ lines ; breadth, ^. 



Habitat, Tairua (iVuckland). 



Dryptops. 



Nov. gen. 



Intermediate between Tarphiomimus and Ulonotus, having the 

 facies of the former, but differing in the less developed basal articu- 

 lation of the tarsi. 



Maxillary i^alpi stout, terminal joint ovate, not acuminate. 

 AntenncB 11 -articulate, basal joint stout, partially concealed from 

 above, second short, third elongate, joints 4-8 sub-obconical and 

 nearly equal ; club large three-jointed. Prothorax deeply lobed at 

 the sides. Elytra serrate laterally, their aj)ices more or less pro- 

 longed and somewhat divergent. Legs moderate ; tibice denticulated 

 externally ; tarsi four-jointed, the three first joints conjointly rather 

 shorter than the last, about equal to one another. Body sub-oblong, 

 longitudinally elevated along the middle, its sides explanate. 



1354- D. dorsalis, '^-5. Griseous; tarsi, antenuaB, palpi, and 

 labrum red ; sub-oblong, transversely convex. 



Head granulated. Prothorax sub-cordate, its sides with deep 

 median indentations, forming two large lobes more or less incised 

 along their margins ; disc considerably elevated longitudinally, 

 broadly canaliculate, bearing two conspicuous frontal protuberances. 

 Elytra oblong, base tri-sinuate, lateral margins serrate, obliquely 

 narrowed posteriorly, apices prolonged, leaving a deep sutural notch ; 

 the dorsum raised, with a rather gradual slope from the sides, so that 

 these latter are not at all vertical, with a row of five tubercular
