658 COLEOPTERA 



the middle, so as to form an angular projection, terminating in a very 

 distinct tooth, the trochanter occupying the space up to that point. 



Under-side black, with a few shallow punctures on the sides of the 

 breast. 



This species might, in some respects, be mistaken for H. ccdicnema 

 (p. 39), but the regularity of the elytral sculpture, plain black colour, and 

 smaller size will lead to its recognition ; whilst the duplicated basal foveie 

 of the thorax, distinctly dentate thighs, and somewhat arcuated hind tihicE 

 are sufficient to separate it from the previously described species. 



Length, 6| lines ; breadth, 2. 



I found one male example near Whangarei Harbour. 



11,49. H. Sternalis, n.s. Body oblong, slightly convex, glossy 

 pitchy-black, legs piceous, antennce and tarsi pitchy-red. 



Head normal, slightly constricted immediately behind the eyes. 

 Prothorax rather broader than long, somewhat cordate, widest at the 

 middle, widely and rather strongly incurved in front, with rounded 

 anterior angles ; the base also is emarginated ; the sides are rounded and 

 a good deal narrowed behind, with rectangular, but not prominent, 

 posterior angles ; its surface slopes a little towards the base, the side rims 

 are rather thick, the median groove proceeds from the hind margin, 

 where it is deepest, but does not attain the apex ; the basal depressions are 

 deep and elongate, extending nearly to the middle of the disc, which 

 is finely impressed transversely. Elytra oblong-oval, but little elevated, 

 very slightly sinuated towards the apices, their humeral angles not 

 prominent ; the discoidal strias are regular but not deep, their punctation 

 fine ; the punctiform impressions beyond the eighth stria are catenulate, 

 and the interstices are plane, the third being tri-punctate. 



The thighs are inflated, but not dentate. 



Under-side shining, piceous ; the sternum and basal abdominal 

 segment are more or less evidently punctured. 



The thorax, so far as I can judge by description alone, is somewhat 

 similar in form to that of H. subcenea (p. 38) ; the finely punctured 

 elytral strias differentiate this species from H. ovatella, whilst the 

 punctures on the third interstices separate it from all but the latter. The 

 distinctly punctured sternum, especially near the sides, forms an almost 

 exceptional feature, though traces of this may be observed in i/. ihoracicus, 

 H. angiistida, and others. 



Length, nearly 6 lines; breadth, nearly 2. $. 



I found one mutilated specimen in the neighbourhood of Whangarei 

 Harbour. 



1 1 50. H. placidus, "-y. ^o^' oblong, slightly convex, broadest 

 behind the middle of the elytra ; shining black, tarsi and four basal 

 joints of the antennaj pitchy-red, the rest of the antenna? obscure-red. 



Head moderate, almost imperceptibly constricted behind the eyes, ex- 

 hibiting the usual frontal impressions and ocular punctures, and, in addi- 

 tion, a well-defined aciculate impression across the occiput. Prothorax 

 quadrate, apex sub-truncate, base emarginate, the sides rounded, narrowed 

 behind, the hind angles projecting a little beyond the posterior sinuation ; 

 it is but little convex, presents the ordinary median groove, expanded a
