1288 COLEOPTEBA 



prominent tufts. Legs and tarsi very densely clothed. Antenna 

 mottled with greyish spots; the base of each of joints 4-11 yellow- 

 ish. Undersurface densely clothed everywhere with fine pubescence. 



This aberrant Xylotoles tends to connect Xylotoles and Tetrorea ; 

 although very different, owing to its clothing, from the other species, 

 I do not see any characters that necessitate at present its generic 

 isolation, unless the coarser granulation of the eyes and shorter head 

 be considered such. 



I received a single individual from Professor Hutton, after whom 

 I have named it, some years ago (1877). It was found by him in 

 Otago. 



2265. X. gaildens, n.s. Elongate, subdepressed, moderately 

 shining, variegate ; femora pale-chestnut or fulvescent, tibiae green- 

 ish, the front pair darker and more spotted with fuscous ; antennae 

 much variegated, joints 2-6 nearly similar to the thighs in colour, 

 with brownish spots, the first fuscous, but with pallid marks caused 

 by the pubescence, 7-11 viridescent or fuscous, paler at the base. 



Thorax broader than long, obtusely prominent at each side 

 behind the middle, much narrowed behind ; there is a distinct 

 transverse depression near the front, and a much larger one behind 

 the middle, with a more or less evident longitudinal one between 

 them, so that there appear to be two small central, obtuse promi- 

 nences ; the surface is densely and minutely sculptured, and, near 

 the base, finely transversely strigose ; the colour, like that of the 

 head, is a dark bronzed brown ; it is sparingly clothed with short, 

 but not slender, pallid hairs. Elytra with a dense, minute sculp- 

 ture, and numerous distinct punctures, these are not regularly dis- 

 tributed, and are not continued to the extremity; the two basal 

 prominences are moderate but not acute, in line with each of these 

 there is an elongate but small crest, and about midway between the 

 latter and the apex there is a curvate patch of yellow pubescence 

 separated from its fellow by the broad suture ; the clothing is not 

 dense, mostly yellowish, rather short, often forming small spots, 

 notably along the suture ; they are broadly depressed before the 

 middle, with a strongly-curved linear impression extending from near 

 each shoulder to the suture ; in front of this curvature the colour is 

 like that of the thorax, behind it it is somewhat rufo-castaneous as 

 far as the hind thighs, the apical portion is infuscate but variegate. 

 Antenna, elongate, eighth joint attaining the extremity, first clavate, 

 the fourth quite one-third longer than the third. 



This species has given me a great deal of trouble. It should, I 

 think, be placed beside X. huttoni. The head is very short, with a 

 deep median channel, so that the tubercles, which are situated on 

 the upper part, seem rather large. The elytra are gradually attenu- 

 ated and dehiscent. It is as much allied to Tetrorea, and the 

 elongate depressed species of Hybolasius, as it is to Xylotoles. 

 No. 1078 is another near ally.
