dense as that of the thorax, so that the surface is distinctly 

 shining, although, when carefully examined, a very fine 

 minute pubescence is found to exist ; and, in addition to 

 this diffuse punctuation, there exists some abbreviated 

 series of fine punctures on the basal portion. Under surface 

 rather regularly and distinctly punctate, the head more 

 densely than the other parts, and with a longer and more 

 conspicuous pubescence. Antennte obscure red, with darker 

 club ; the 1st joint concealed under the side of the head ; 

 2nd joint short and stout ; 8rd very slender and elongate, 

 as long as the three or four following joints together ; 

 8th excessively short,'lenticular ; 9th to 11th forming an 

 elongate club, very densely covered with fine sensitive 

 pubescence,

Species of this genus are widely distributed in both 

 hemispheres. Broun (' Manual,' p. 242) has described a 

 Nosodendron ovatum, which is no doubt a very distinct 

 species from that here described, and may even be 

 generically distinct. The New Zealand insect has the 

 tibiaB less remarkably formed than in any of its allies 1 

 have seen.

This is a curious species, and the sexes are very unlike, 

 even as regards colour, sculpture, and clothing. 



In the male the head is about half the width of the 

 thorax, its anterior angles \exy prominent, the man- 

 dibles not quite so long as the head, and curved so as 

 only to come into contact with one another at the tips, 

 and so appearing from above to enclose a comparatively 

 large vacant space ; the upper surface of the head bears 

 coarse round punctures, and some erect hairs or scales ; 

 these are most conspicuous behind the eyes. The maxillary
