HAPLONTCHIDAE. 571 



subopaque, piceous, the thoracic apex, extremity of elytra, and the antennae 

 rufescent ; sparingly clothed with siiberect, somewhat curled, tawny setae. 



Rostrum indistinctly sculptured, of normal form. Thorax a third 

 broader than long, gradually narrowed towards the front, moderately but 

 not at all closely punctured. Elytra scarcely twice the length of thorax, 

 just as wide as it is at the base, their sides moderately rounded, a good 

 deal narrowed but not vertical behind ; distinctly striate-punctate, quite 

 striate behind, with simple interstices. Tibiae without external prominences. 



This small species may be known by the absence of special features, 

 ■even the tibiae being simple. 



Length (rostrum inclusive), 1^ mm. ; breadth, 1 mm. 



Mount Te Aroha. Three, found by myself, during October, 1911, on the 

 ground amongst dead leaves, at an altitude of about 1,000 ft. 



Group Cryptorhynchidae.

Robust, convex, subovate, uneven, subopaque, the derm nitid, nigres- 

 cent ; covered to a great extent with small, depressed, obscure ferruginous 

 squamae, but the basal portion of each elytron from the third interstice 

 to the shoulder is unevenly clothed with coarser, pale-tawny scales ; 

 antennae and tarsi light fusco -rufous. 



Rostrum moderately broad and arched, slightly narrowed towards the 

 middle, as long as thorax, rufescent ; its distinct punctation not seriate but 

 disposed longitudinally and becoming finer near the extremity, with a fine 

 mesial carina. Eyes free, subrotundate, nearly fiat. Thorax hardly a third 

 broader than long, its contracted frontal portion with a pair of small 

 greyish crests ; its basal half with a pair of dark median crests and an 

 indefinite median carina ; the front of each side, of this basal part, has a 

 dark crest, and the short outstanding scales extend from it along the side 

 to the base ; its moderately coarse punctation is almost hidden. Scutellum 

 indistinct. Elytra of about the same width as thorax at the base, a little 

 broader behind, fully double its length, their sides nodose, posterior declivity 

 sloping and narrowed ; they are irregularly and coarsely subseriate-punc- 

 tate ; third and fifth interstices unequally and obtusely bicristate behind 

 the middle, the hind one of the fifth is placed nearly half-way down the 

 declivity, the suture is plane, but the rest of the surface is slightly asperate 

 and bears a few small black granules. 



Scape inserted just before the middle, reaching the front of the eye, 

 incrassate near the extremity, almost glabrous ; funiculus finely setose, its 

 basal joint obconical, thicker but shorter than the elongate second, third 

 and fourth oblong, joints 5-7 moniliform, the seventh rather broader than 

 the others yet considerably narrower than the ovate, triarticulate club. 



Legs elongate, with slightly variegated squamae, femora broadly grooved 

 underneath ; tarsi rather narrow, not sponge-like below, penultimate joint 

 only moderately expanded and lobate. 



Pectoral canal profound, its thick vertical borders almost touching the 

 posterior coxae. Metasternum concave and almost invisible between the 

 coxae. Abdomen covered with greyish and ferruginous scales, its first 

 segment twice the length of second, their suture nearly straight, fifth as 

 long as the moderately developed third and fourth togetlier, with a large 

 fovea at each side.
