OF NEW ZEALAND. 103 



segments rufescent, the first four transversely lineated and depressed 

 near the base ; it is very sparingly punctulate, and a few fine hairs are 

 scattered over its surface. 



The four basal joints of the antenna are, more or less, shining red, 

 the others dull with fine pubescence ; the first joint is larger than the 

 second and third, the last larger than the tenth. 



Length, 8 lines ; breadth, nearly ij. 



I found five or six specimens of this fine species, which I have much 

 pleasure in naming after Dr. Sharp, of Dumfriesshire. 



189. X. CllltuS, n.s. Head and thorax shining black, elytra nearly 

 similar in colour but with reddened shoulders, hind-body infuscate, the 

 fourth and fifth segments blackish, legs red, antennae pitchy red. 



Head large, broader than thorax, quadrangular, with two inter- 

 antennal excisions ; it is remotely punctured, especially behind, but in 

 front some of the punctures are confluent, the transversal space between 

 the eyes and antennae is quite smooth but divided by two longitudinal 

 depressions ; its sides are nearly vertical and almost impunctate. Pro- 

 thorax with its base sub-truncate, oblong, rather narrow, widely but not 

 deeply contracted in the middle, its front angles oblique ; the dorsal 

 line is smooth, on each side of it there is a more or less distinct row of 

 nine or ten punctures, and several others are irregularly disposed near 

 the sides. Scutellum large, triangular, impunctate. Elytra of the same 

 length as the prothorax, but broader than it behind, their apices a little 

 rounded, with shallow punctation, and a few short scattered hairs. 

 Abdomen long, rather narrow, distinctly punctulate, very sparsely 

 clothed with rather long hairs similar to those observable on the sides of 

 the thorax. Legs rather short, sparingly pilose ; the anterior and inter- 

 mediate tibia spinous externally, the former densely clothed inwardly, 

 the latter ciliated below, with yellow pubescence, the posterior almost 

 simple. 



Left mandible with a strongly developed median tooth, the other 

 almost simple. Labrum emarginate. Antenna normal, their four basal 

 joints dark shining red, the others covered with fine cinereous pubescence. 



The broadest part of the insect is its head, which has been measured 

 for the breadth. Differs from X. sharpi in its narrower body, but rela- 

 tively broader, quadrate, and quite differently sculptured head. 



Length, 7^ lines; breadth, ij. 



A second example measures six by one. I found both at Parua. 



190. X. arecse, n.s. Elongate, depressed ; body shining black, 

 the elytra and hind-body sometimes infuscate, legs reddish-testaceous 

 or yellowish, tarsi yellow, antennae red. 



Head large, quadrate, depressed ; the sides behind the eyes well- 

 defined by a straight carina and nearly smooth, two elongate frontal 

 depressions terminate in punctiform impressions, and the remainder of 

 its surface is more or less finely and remotely punctate; the neck is 

 quite smooth. Prothorax scarcely so broad as the head, oblong, nar- 

 rowed posteriorly, with oblique anterior angles ; it is obsoletely punc-
