594 COLEOPTERA 



being more brassy greenish and shining, especially on the thorax. The 

 general laid pubescence is grayish, and the striae and punctures are 

 nearly the same as in X. griseus ; but the denser pubescent spots are 

 always orange-tawny and conspicuous arranged in two groups one near 

 the base (some of them forming an oblique line), and the other behind 

 the middle, (forming a line oblique in the opposite direction to the 

 former). The orbit of the eyes has also a dense fringe of the same 

 tawny-coloured hairs ; and there is a patch of the same on each side of 

 the thorax. 



Many examples from Mr. Lawson of Auckland, mixed with X. 

 griseus.

South Island (Mr. Earl.) 



NOTE. According to Mr. Bates " it resembles X. griseus, but has a 

 more spotty pubescence, and the elytra are more prolonged and pointed 

 at the apices." I have not seen this species, and do not know its 

 size. 



1036. X. nudUS, Bates; Ann. Mag. Nat. Hist., July, 1874. 

 X. elongatus, angustus, cuprascenti-niger, glaber, nitidus ; elytris basi 

 thorace vix latioribus, apice utrinque productis et paulo divaricatis \ basi 

 grossissime lineatim punctatis ; antennis pedibusque castaneis ; femori-

Long., 4J-5 lin. 



Body entirely destitute of pubescence, except spots on the sides of 

 the ventral segments ; antennae and legs finely griseous pubescent. 

 Colour glossy coppery-black ; head and thorax impunctate and smooth. 

 Elytra elongated, not perceptibly broader at the base than the thorax, 

 very slightly bulging in the middle and gradually narrowed and pro- 

 longed at the apex, where they are slightly divaricate ; the surface has 

 rows of very large punctures from the suture to the sides and extending 

 to the middle. 



Several examples sent from Auckland by Mr. Lawson. 



1037. X. rUgiCOlliS, Bates; Ann. Mag. Nat. Hist., July, 1874. 

 X. /ktttf-niger, sub-aeneus, nitidus; thorace elongato-quadrato, supra 

 passim transverse rugato ; elytris ellipticis, apice utrinque productis, 

 acutis, supra striatis interstitiis elevatis, fulvo-guttatis ; antennis pedibus- 

 que castaneis. 



Long., 4-6 lin., M.F. 



Distinguished by the thorax being elongate-quadrate in outline, a 

 little dilated immediately behind its anterior angles, where it is widest, 

 and covered with irregular transverse wrinkles. The sides have some 

 patches or lines of tawny pubescence, as well as the front of the head. 

 The elytra have no distinct shoulders, and are dilated in the middle,
