.ColydiidfB of New Zealand. 27 



prothorace subquadrato, basin versus angustato, elytris fere duplo 

 angustiore, inaequali ; elytris rugosis. Long. corp. 2-2| m. m. 



Antennse reddish ; joints 3-9 slender, tenth abruptly larger, 

 strongly transverse ; eleventh large, quite as broad as the tenth. 

 Head rather short, rather strongly constricted behind to form 

 the neck, rugose. Thorax small, widest at the front angles, 

 gradually narrowed towards the base, the front angles acute ; 

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

 impressions. Elytra uneven, their sculpture coarse but in- 

 distinct, and their pubescence or setje variegated, its most 

 conspicuous parts being some small, white, slightly elevated 

 tubercles. Legs reddish ; underside nearly black.

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

 the other species of the genus 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 Xylolcemus fasciculatus is, I judge, 

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

 though B. rugosa does not possess the peculiarly slender basal 

 antennal joints oi Xyloloimus, yet it is probable that it may be 

 ultimately considered to be as much allied to Xylolcemus as to 

 Bitoma crenata. 



Bitoma nana, n. sp. 



B. fusco-testacea, supra testacea, elytris (prsesertim in lateribus) 

 fusco-maculatis ; prothorace basin versus angustato, lateribus 

 serratis ; elytris aequaliter 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 serrate, the front angles not acute ; it 

 is yellowish in colour, rough and dull, and with very 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 settfi. The legs are yellowish, short and stout ; 

 the femora somewhat infuscate. 



A single specimen, sent from Tairua by Captain Broun. 



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

 dius. It appears, however, to be closely allied to B. rugosa, 

 but is very readily distinguished by the pale colour and the 

 more ragged sides of the thorax.
