Species of New-Zealand Coleoptera. 215 



the type, is like Ammohius rufus and is about the same size, 

 apparently scaleless ; but I suspect when perfectly fresh it is 

 otherwise: the second species, A. albata is a pretty little 

 insect clothed with close-set white scales having a somewhat 

 varnished gloss, but generally marked with a few dark more 

 or less indistinct spots. All the tibise are armed at the 

 interior angle of the apex with two long spines. 



Actizeta ammobtotdes. 



A. ovalis, castaneo-fusca, subtilissime crebre punctulata ; antennis 

 ferrugineis, clava articulis bene determinatis ; prothoracc transverso, 

 basi in medio caualiculata et bifoveata ; elytris striato-punctatis, 

 striis secundo tertioque subflexuosis, interstitiis parum convexis ; 

 corpore infra sparse punctato ; pedibus colore dilutiore ; tibiis 

 setulosis. Long. 1^- 1| lin.

A. ovata, nigra, squamis albis, aliquando maculatim nigrescentibus, 

 dense tecta ; antennis brevioribus ; clava articulis arete contiguis ; 

 capite protboraceque rarissime punctatis, hoc fortiter transverso, 

 basi in medio impressa ; elytris striatis, striis subflexuosis, inter- 

 stitiis rarissime uniseriatim punctulatis ; corpore infra pedibusque 

 ferrugineis, squamis albis adspersis. Long. lg-l| lin. 



Hob. Waikato. 



In most specimens there is a dark round blotch on the 

 middle of each elytron, and vestiges of two or three smaller 

 spots on the prothorax. 



Sykphetodes. 



Caput depressum ; chjpeus apice truncatus ; labrum productum ; 

 palpi maxillares elongati, labiales brevissimi ; mentum transver- 

 sum ; oculi rotundati. Antennas tenues, articulis tribus ultimis 

 clavam formantibus. Prothorax transversus, basi angustatus, apice 

 profunde emarginatus. Elytra convexa, subcordata ; epipleura; 

 latse, integrae. Pedes tenuati ; tibiae cylindricse, apice breviter bi- 

 spinosae. Coxae posticse subapproximatae. 



The head is slightly concave between the antennae ; the 

 latter are nearly free at the base, owing to the small size of 

 the antennary orbits ; for the same reason the eyes preserve 

 their rounded outline. The clypeus is rather narrowed 

 anteriorly, and shows no trace of any line of separation from 

 the front. The tarsi are filiform, and the claw-joint is nearly 

 as long as the rest together, especially of the anterior pair.
