ColydiidiE of Xew Zealand. 27 



prothorace subquadrato, basin versus angustato, elytris fere duplo 

 angiistiore, intcqunli ; elytris nigosis. Long. corp. 2-2^ m. m. 



Antennae retldisli ; joints 3-fJ slender, tenth abruptly lar;:^or, 

 stron^^ly transverse ; eleventh large, quite a.s broad as the tenth. 

 Head rather short, rather stronj[(ly constricted behind to form 

 the neck, ruf^ose. Thorax small, widest at the front angles, 

 gradually narrowed towards the base, the front angles acute ; 

 the surface rugose, and occupied by several ill-defined large 

 impressions. Elytra uneven, their sculpture coarse but in- 

 distinct, and their jiubescence or seta3 variegated, its most 

 conspicuous parts being some small, white, slightly elevated 

 tubercles. Legs rcddisli ; underside nearly black.

Ohs. The facies of this little species is very different from 

 the other species of the geiuis I know, owing, I think, chiefly 

 to the form of the thorax ; but the general points of structure 

 seem to be those of the genus to which I have assigned the 

 species. The European Xyhla^mus fasciculatus is, I judge, 

 according to Duval, similar in appearance to this species ; and 

 though B. rugosa docs not possess the peculiarly slender basal 

 antennal joints oi XyJohrmus^ yet it is probable that it may be 

 ultimately considered to be as much allied to Xylolcemus as to 

 Bitonia creriata. 



Bitoma nana^ n. sp. 



B. fusco-testacea, supra testacea, elytris (pra^sertim in lateribus) 

 fusco-maculatis ; prothorace basin versus angustato, lateribus 

 serratis ; elytris ajqualiter scabrosis. Long. corp. If m. m. 



Antennae with joints 3-9 small, tenth and eleventh large. 

 Head short, yellowish, quite rough and dull. Thorax much 

 narrower than the elytra, a good deal narrowed towards the 

 base, the sides coarsely seiTate, the front angles not acute ; it 

 is yellowish in colour, rough and dull, and with veiy indistinct 

 large impressions. Elytra yellowish, with some indistinct 

 dark marks on the middle, and a large one covering most of 

 the side ; their sculpture is very indefinite, but consists appa- 

 rently of regular rows of coarse punctures, the interstices be- 

 tween which are narrow and interrupted ; and they are hispid 

 with short erect seta?. The legs are yellowish, short and stout ; 

 the femora somewhat infuscate. 



A single specimen, sent from Tairua l)y Captain Broun. 



This minute species in size and form much suggests a Latri- 

 dius. It appears, however, to be closely allied to /?. rugosa, 

 but is very readily distinguished by the pale colour and the 

 more ragged sides of the thorax.
