Colydiidte of Neic Zealand. 19 



sides of the thorax considerably deeper, and the setae of the 

 under surface much finer. The surface of tlie thorax and 

 elytra is very similar in the two species (the green nodules of 

 T. viridipictus being, I judge, not constant in colour) ; the 

 surface of the thorax is very uneven, but still without distinct 

 nodules ; the elytra bear numerous nodules, which, however, 

 are not very distinct, and their colour is a patchwork of sober 

 green and grey, with a little black intermixed. 



Three individuals sent from Tairua by Captain T. Broun. 



TJlonotus asper^ n. sp. 



U. piceo-ferrugineus, marginibus dilutioribus, antennis pedibusque 

 rufis ; oblongus, subdepressus ; prothoracis lateribus trUobatis, 

 lobis diiobus posterioribus angustis, et bene separatis ; elytris 

 crebre asperatis, ante apicem tuberculis nonnullis sat elevatis. 

 Long. Corp. 3j m. m. 



Antennae, including the club, red. Thorax transversely 

 convex, with the surface rough, and showing some indistinct 

 depressions ; the front angles acute and prominent ; at the sides 

 in the middle is a broad and deep indentation, and in front of 

 the hind angles there is a second rather smaller indentation ; 

 the part separating these two indentations is narrow ; and the 

 third or posterior lateral lobe is, though very prominent, very 

 narrow. The elytra are pitchy in colour, with the base and 

 the margins pitchy ; their surface is very dull, and is densely 

 covered with very rough granules, and a little before the apex 

 there are three or four not very distinct tubercles on each ; the 

 lateral margin is finely and densely serrated. The legs are 

 entirely red ; and the under surface is nearly destitute of any 

 pubescence or scales. 



Tairua ; a single individual sent by Captain Broun. 



This species in its form resembles Tarphiomimus indentatus^ 

 Woll. ; but it cannot be associated with that species, on account 

 of the minute basal joints of the tarsi. It much resembles a 

 small Endophloeus spinosulus ; and, as in that species, the sur- 

 face on its protected parts is covered Avith a peculiar pale 

 exudation, 



Coxelus duhiuSj n. sp. 



C. oblongus, angustulus, parallelus, piceus, antennis pedibusque rufis, 

 supra dense breviterque bispidulus, subvariegatus, subtus breviter 

 griseo-setosus ; tibiis extus hispidulis. Long. Corp. 2^ m. m. 



Antennge short, red, 11-jointed, the basal joint scarcely 

 visible from above ; second a good deal larger than the fol- 

 lowing ones ; third small, but distinctly longer than the fol- 

 lowing joints, the fourth to eighth being small, ninth small but
