pointed. The colours and sculpture of both species are very much 

 alike, but the rounded thoracic depressions of C. perpinguis are absent.

I found several specimens in the Parua forest, near Whangarei 

 Harbour. 



FAMILY TENEBRIONIDES. 



* 



Mentum borne by a peduncle of the under-chin, more or less promi- 

 nent. Ligula sometimes hidden by the mentum, sometimes exposed, 

 furnished with paraglossae. Maxilla bilobed ; the inner smaller, often 

 terminated by a corneous hook. Mandibles short, robust, arched exter- 

 nally, hollowed inwardly, and provided with a stout molar tooth at their 

 base. Eyes generally large, transversal, emarginate or sinuate in front. 

 Antenna, with eleven, rarely with only ten joints, inserted laterally in 

 front of the eyes, under the side of the head. The coxa never contig- 

 uous : the anterior globose, occasionally slightly transverse, their cotyloid 

 cavities closed behind ; the intermediate often provided with trochantins ; 

 the posterior transversal. Tarsi heteromerous ; the two front pairs with 

 five, the hind pair with four joints ; their claws simple. Abdomen com- 

 posed of five distinct segments, the penultimate shorter than the others. 



Group OP ATRID^E. 



Ltgula prominent, seldom hardly visible; its paraglossae inserted 

 laterally at its base. Maxilla uncovered, their internal lobe with a 

 corneous hook. The apical joint of the labial palpi never triangular, 

 that of the maxillary of variable form. Head immersed in the prothorax 

 up to the eyes, these latter visible above ; epistome short, nearly always 

 rounded and narrowly incised in front, lodging the labrum in the 

 hollow, and covering the mandibles. Antenna eleven-jointed, gradually 

 incrassated, their terminal joints perfoliate, or forming a small club. 

 Prothorax margined laterally, hollowed in front. Scutellum small but 

 distinct. Elytra feebly embracing the abdomen. Anterior coxse a little 

 transversal among the greater number, the posterior of variable form. 

 Anterior tibia very often dilated and dentate outwardly; the spurs 

 rarely developed ; tarsi prickly or ciliated in nearly all. Projecting 

 intercoxal process of variable width, usually parallel. Metasternum often 

 elongated ; its episterna more or less narrow and parallel, epimera dis- 

 tinct. Mesosternum rather broad. Mesothoracic epimera posterior and 

 oblique. Body often winged. 



Syrphetodes. 



Pascoe ; Ann. Mag. Nat. Hist., September, 1875. 



Caput depressum ; clypeus apice truncatus ; labrum productum ; 

 palpi maxillares elongati, labiales brevissimi ; mentum transversum ; 

 oculi rotundati. Antenna tenues, articulis tribus ultimis clavam forman- 

 tibus. Prothorax transversus, basi angustatus, apice profunde emargi-
