BHARP.—On the Colydiide of New Zealand. 401 
nigricante; antennis articulis duobus ultimis subclavatis. Long. 
corp. 2-3 m.m. 
Antenne reddish, short; the two basal joints stouter than the following 
ones, joints 8-8 small and bead-like, tenth joint subquadrate, both broader 
and longer than the preceding joints; eleventh joint almost oval, quite as 
broad and two or three times as long as the tenth. Head very variable in 
size, abruptly constricted at the neck, the forehead rather convex; it is of 
a reddish colour and rugose, but hispid, so that the sculpture is concealed, 
Thorax transversely quadrate, straight at the sides, a little narrower than 
the elytra, the surface rugose and hispid. Elytra rather elongate and 
parallel, similar in colour to the head and thorax ; their sculpture very 
coarse but indistinct, and consisting of rows of coarse punctures separated 
by narrow interstices, hispid, being clothed with both long and short setze, 
Underside pitchy black ; the metasternum coarsely but sparingly punctured. 
Legs red, short, hispid. 
Several specimens sent from Tairua by Captain Broun; one of them 
was sent amongst a lot of Coleoptera found on Cyathea dealbata, one of the 
tree ferns. 
Obs. The structure of the antennz», as well as their insertion, seems to 
justify the location of this insect in the Colydiide. The anterior coxæ are 
very small, and their cavities completely closed behind ; and this is the 
only character, so far as I can see, which would throw any doubt on the 
propriety of the association mentioned. Mr. Wollaston, in calling attention 
to the peeuliarities of this important genus, has already suggested its 
affinity with the Colydiide. The New Zealand insect I have here described 
approaches the Aglycyderes setifer closely in appearance ; but it differs in the 
structure of the antennæ, as well as in its remarkably widely separated 
anterior coxe. The Colydiide as a group is one of the less specialized of 
the Coleopterous groups ; and it is not therefore surprising that we should 
find some of its members exhibiting wide and puzzling affinities, I am 
unable to see any close ralationship in Aglycyderes with Bruchide and Anth. 
ribide ; and if the genus be not accepted as an aberrant member of. the 
Colydiide, I think there is no other course but to do as Mr. Wollaston has 
suggested, viz., to regard it as representing a distinct family of Coleoptera.
