basal joint, the second is distinctly longer than the third, which is of the 

 same thickness as but longer than the fourth ; joints four to eight are about 

 equal in width, but decrease a little in length; the ninth is a little 

 larger than eighth;, the tenth transverse, eleventh larger and rounded, 

 both together forming a well-limited club. Head seemingly impunctate ; 

 on a careful examination, it will be observed that what seems at first 

 sight to be the eyes, is, in reality, an acute lateral angulation bearing the 

 minute black eyes at the extremity. 



Prothorax slightly longer than broad, a little rounded in front, the 

 sides otherwise straight, base a little bisinuated, with acute angles ; its 

 discoidal portion is distinctly but distantly punctured, the sides are 

 nearly impunctate. Elytra moderately elongate, widest near the 

 middle ; they bear punctate, rather indistinct strise, which become 

 obsolete posteriorly. Legs stout ; femora somewhat distended, particu- 

 larly the posterior ; tibia slender above, but a good deal dilated towards 

 the extremity, the anterior being considerably thickened. 



The body is sparingly clothed with fine elongate erect yellow hairs. 

 The abdomen is smooth, the breast punctate. Legs and antenna 

 pubescent. Palpi of normal structure, yellow. 



Length, i \ ; breadth, less than J line. 



I found two specimens, one unfortunately mutilated, near Whangarei 

 Heads. The species is well differentiated from the others by the 

 peculiar form of the head, and might, perhaps, be made the type of a 

 new genus. 



Adelostella. 



Nov. gen. 



Body elongate, sub-parallel, sub-depressed. Antenna stout, rather 

 short, inserted near the base of the mandibles ; they are eleven-jointed, 

 not perceptibly clavate, with a stout cylindric basal joint ; second short 

 and stout; third about as long as first, slender at the base, its apex 

 incrassate ; joints four to eight sub-moniliform, about equal to one 

 another ; ninth distinctly broader than the others, its base and apex 

 rounded ; tenth nearly as large as the preceding one, of nearly the 

 same shape ; eleventh round, not much larger than the eighth. Mandi- 

 bles very stout, their apex bifid. Labrum small, deflexed. Epistome 

 large, depressed, broad at the base, with a distinctly depressed suture, 

 sides oblique. The head is gradually dilated from the front backwards, 

 being produced behind in the form of an obtuse lobe at each side, and 

 the basal portion between these lobes forms a neck as wide as the front 

 of the thorax. The eyes are prominent, circular, and situated at the 

 sides, midway between the antennse and extremity of the lobes. The 

 prothorax is rather longer than it is broad ; from the base to beyond the 

 middle sub-quadrate, and as wide as the lobed portion of the head, the 

 anterior portion being rounded and narrowed to the width of the con- 

 stricted basal portion of the head ; base and apex sub-truncate. Scutel- 

 lum transverse. Elytra elongate, depressed, finely margined, sides some- 

 what compressed, apices obtusely rounded. The two front pairs of
