Species of Xew- Zealand Cohoptera. .'0 



Rost rum owc-iWwCi shorter than thorax, iiulistiiictly medially 

 ri(l;:etl, broadly l>iiinpris'<e(l neiir the base. Scrobes oblicjuc, 

 (h'('|) ami broad Iroiii tin.- apex io beliiiid the middle, squumosc 

 behind. Ilcdtl short, not niiieh broader than the rostrum. 

 Eyes v«Ty prominent, obli(|nely oviform, {jnitc lateral, ju.st 

 free from the thorax. Club larj^e, ovate, snbaenminate, 

 in<listinetly cjnadriartienlate, densely pnbescent. Thorax of 

 ecjnal length and breadth, widest and (d>tnsely prominent 

 before tlie middle, base and apex truncate; disk a little 

 Tiiu'ven, haviii}^ an impression near cath front anj;le and 

 another at eaidi side of the middle in front ; there is no 

 dilinite j)»inctnation, but there are several small shininj^ 

 blaek granules. Elytra sidieordate, slightly obtusely promi- 

 nent and widest behind the oblique shoulders; the base, 

 however, hardly exceeds that of the thorax in width, their 

 apical portion much narrowed ; they are sliglitly uneven, 

 with indistinct, coarse, more or less seriate pnnctnrcs; there 

 are two small (d)tuse l)asal elevations and four on top of the 

 posterior declivity, those on the disk (about four on eacdi 

 elytron) are less definite ; at the suture near the base there 

 are several small black shining granules. 



H. oculatus is most like this species, but has a longer and 

 more eylindrieal thorax, with a more definite continuous 

 meciian ridge. In H. oscitans and H. verrucosus the two 

 broad rostral grooves are separated by a well-marked carina 

 extending from the apex to the eyes. 



In this genus there are no ocular lobes or any distinct 

 exterior truneat'ire of the posterior corbels. The meta- 

 sternnm is very short, not being longer than the middle of 

 the second ventral segment.

Rostrum as long as thorax, nearly as broad as the head.
