560 COLEOPTERA 



ted second joint ; claws large and strong, apparently simple. The under- 

 side of thorax is coarsely punctate, the abdomen finely. All the coxa 

 are distant, the anterior pair least so, yet rather remote from each other. 



Length, i line. 



This is a quite distinct form, having no near described allies, so far 

 as I am aware. I found a few examples recently at Tairua.

 capite haud rostrato, oculis sub-convexis, brevis, transversim convexus,

Long, corp., 2 mm. 



Carina of thorax quite basal ; antennae inserted at inner margin of 

 eyes. Head small and much inserted in thorax, with a fine dense and 

 indistinct punctation. Eyes rather large but not very prominent, their 

 inner edge scarcely rounded and taking an oblique direction ; along 

 this inner edge of the eye and at some little distance behind its most 

 anterior part is the point of insertion of the antennae ; there is no 

 distinct cavity for their reception. The parts of the mouth are very 

 small, and the front of the clypeus is truncate. The antenna are pitchy, 

 except the two basal joints which are yellowish ; they are slender and 

 about as long as the thorax ; the first joint is rather slender, and has its 

 inner edge only moderately curved ; the second joint is about as stout 

 as the first and rather shorter than it ; joints three to eight are very 

 slender, each is distinctly shorter than its predecessor, the eighth being 

 but short ; joints nine, ten, and eleven form a long slender and very 

 laxly articulated club, each of them being quite narrow at the point of 

 insertion. Thorax rather large, a good deal narrowed towards the front, 

 the disc a little elevated, covered with a dense fine rugose sculpture and 

 only with excessively indistinct pubescence ; its carina is close to the 

 elytra and follows the direction of their base so as to form the hind 

 angle of the thorax, which is about a right angle ; it is continued at the 

 sides not quite halfway forward to the front ; this part of it, however, 

 is but little conspicuous. Elytra clothed with a fine black pubescence, 

 and on the middle with a small ash-coloured mark ; the basal part of 

 each near the suture is a little elevated, and the rest of the surface is 

 rather uneven with indistinct elevations and depressions ; the rows of 

 punctures are distinct, but not very regular. The pygidium is moder- 

 ately large ; and the penultimate dorsal segment appears to be grooved 

 in the middle for the apex of the elytra. The legs are nearly black, 

 except the tarsi, which are reddish. The anterior coxa are quite contig- 

 uous ; the middle and hind coxae are rather widely separated. The 

 second joint of the tarsus is but little distinctly emarginate ; the third 

 joint is small and cleft to the base, so as to consist of two narrow lobes. 



The nearest described ally of this species is probably the Dysnos 

 semiaureus of Pascoe, from the Malay archipelago. The appearance of 

 that species is said to be that of a Scolytid ; Anthribus crassus suggests 

 to me rather the appearance of a minute Chlamys-\faz insect. The fine
