448 SHARP—On New Zealand Coleoptera. 
Antenne elongate; third joint longer than second; tenth much longer than 
broad; terminal joint still more elongate. Head very sparingly punctate; the 
clypeus more closely. Thorax about three times as broad as long; sparingly 
punctate. Scutellum moderately large and elongate, impunctate. Elytra each with 
nine series of punctures, the external indistinct, and all becoming quite obsolete 
behind; between the suture and the first stria there are three or four punctures 
interpolated near the base; legs pale yellow, coxze brownish; middle of the body 
beneath zeneous. The male has the basal joint of all the tarsi much larger than 
it is in the female.

Caccomolpus plagiatus, n. sp.—Rotundato-ovalis, convexus, nitidus, testaceus, 
elytris basin versus plaga magna transversa nigro-fusca, obsolete seriatim punctatis. 
Long. 4 m.m. ; 
Antenne pale yellow, elongate, slender; third jomt a good deal longer than 
second. Head impunctate, bi-impressed between the eyes. Thorax with numerous 
rather large punctures irregularly distributed. Elytra near the base with a very 
large patch of dark colour extending nearly but not quite to the side margin; near 
the outside this patch is prolonged in front so as to touch the base, and behind it 
is also longer externally than it is at the suture, being externally about half the 
length of the elytra; the scanty serial punctuation is very much effaced; the legs 
are rather long; the external sinuosity of the tibize very pronounced : on the under- 
surface the middle of the breast is dark, the rest pale. 
Greymouth, Helms: I am indebted to Herr Reitter, of Vienna, for the only example I have seen of 
this distinct species. 
TRACHYTETRA (nov. gen. Halticinorum). 
Acetabulze anteriores apertee; pronotum absque sulca transversa;  tibize 
posteriores apice breviter calcarato ; metasternum brevissimum. 
Antenne moderately long and stout, 11-jointed ; anterior cox only slightly 
separated ; mesosternum not in the least impressed ; metasternum so short that the 
hind coxee are only slightly separated from the middle; himd cox moderately 
separated ; femora strongly dilated ; hind tibia slender, armed at the apex with a 
short mucro directed outwards; tarsi rather short, their basal joint one-third of the 
length of the tibia; claw joint small; claws minute: the other tibize without 
mucro; epipleura rather narrow, completely disappearmg some distance before the 
extremity. 
The type of this genus is a remarkable little Halticid with very coarse punctuation, and the 
shoulders of the elytra very rounded; it was found at Auckland by Lawson, and is, I believe, the
