OF NEW ZEALAND. 95 



Length, 2 J lines ; breadth, quite J. 



I have six or seven examples in my collection, all of which were 

 found at Tairua and near Whangarei Harbour. 



174. D. thoraciCUS, n.s. Antenna short and robust, similar in 

 structure to those of D. flavescens, their terminal joint as long as the 

 preceding two ; they are reddish. Head red, shining, densely punc- 

 tured, with a few yellow hairs. Thorax rather shorter than the elytra, 

 shining, red, not closely punctate, with yellow pubescence, and having a 

 basal, frontal, and two lateral depressions. Elytra glossy yellow, with 

 similarly coloured pubescence, finely punctate. Abdomen bright red- 

 dish-brown, a little variegated, clothed and sculptured as in D. aerarius. 

 Legs reddish-testaceous. 



Smaller then the previously described species ; the head, thorax and 

 elytra more shining, and easily recognised by the four thoracic depres- 

 sions, the middle ones longitudinal, the lateral transversal, sometimes 

 forming a cross on the disc. 



Length, ij-if ; breadth, less than J line. 



I found three specimens near Whangarei Harbour. 



175. D. fulgens, n.s. Antenna short, robust, pale red, normal. 

 Head red, the small inter-antennal space (owing to its fine dense punc- 

 tation) quite dull, the rest shining ; it is somewhat flattened above, 

 depressed near the point of insertion of each antenna, with two fine 

 impressed lines behind, one on each side of the vertex, the latter part 

 not perceptibly punctate, but the sides behind the eyes quite dis- 

 tinctly punctured. Prothorax red, shining, finely punctulated, with 

 distinct frontal and basal depressions. Elytra bright, red at the base, 

 but merging gradually into the yellow posterior portion, finely punctate, 

 with yellow pubescence. Hind-body brownish-red, its fifth segment 

 blackish, its sculpture and clothing quite orthodox. Legs reddish-tes- 

 taceous. 



The insect does not differ materially in form from its predecessors, 

 but may be easily separated from them by the peculiar sculpture of its 

 head. 



Length, ij; breadth, nearly line. 



I found one specimen at Parua, near Whangarei Harbour.

Stilicioides. 



Nov. gen. 



Labrum transversal, with a membraneous space behind. Mandibles 

 covered by the labrum. Maxillary palpi long, their second and third 

 joints equal, gradually dilated, the fourth aciculate ; the labial tri- 

 articulate. Head large, rather broader than the thorax, orbicular, 

 attached to the thorax by a slender neck. Eyes small, oblique, rounded, 

 not prominent, situated near the front. Antenna long, filiform ; their 

 four basal joints about equal, joints five to ten decrease in length but
