ACTIZETA. 
Caput iransverum, antice rotundatum. Antenne validiuscule, 11-arti- 
culate, articulis duobus basalibus ampliatis, equalibus, tertio minore, 
ceteris ad octavum valde transversis, gradatim incrassatis, tribus 
ultimis clavam oblongam formantibus. Oculi liberi. Palpi maxil 
lares articulo ultimo breviter subeylindrieo. —Prothorac transversus 
convexus, lateribus haud ciliatus, basi rotundatus, antice late emar- 
ginatus. Elytra breviter obovata, prothorace vix latiora. Tibie 
antice dilatate, extus profunde emarginate, lobo elongato terminate, 
angulo interiore spinis duabus instructo ; tarsi lineares, antici liberi, 
intermedii et postici elongati. 
There are two species of this genus: one, 4. ammobioides, the iype, is 
like Ammobius rufus and is about the same size, apparently scaleless ; but I 
suspect when perfectly fresh it is otherwise; the second species, .4. albata 
is a pretty little insect clothed with close-set white scales having a some- 
what varnished gloss, but generally marked with a few dark more or less 
indistinct spots. All the tibiæ are armed at the interior angle of the apex 
with two long spines. 
Actizeta ammobioides. 
A, ovalis, eastaneo-fusea, subtillissime crebre punctulata ; antennis fer- 
rugineis, clava articulis bene determinatis ; prothorace transverso, 
basi in medio canaliculata et bifoveata ; elytris striato-punctatis, 
striis secundo tertioque subflexuosis, interstitiis parum convexis ; 
corpore infra sparse ,punctato: pedibus colore dilutiore; tibiis 
setulosis. Long. 14-14 lin. 
Hab: Great Barrier Island. 
Actizeta albata. 
A. ovata, nigra, squamis albis, aliquando maculatim nigrescentibus, 
dense tecta; antennis brevioribus; clava articulis arcte contiguis ; 
capite prothoraceque rarissime punctatis, hoc fortiter transverso, 
basi in medio impressa; elytris striatis, striis subflexuosis, inter- 
Under a high power of the microscope the exceedingly minute scales are seen to 
radiate from a common base; the patches thus formed appear under an ordinary lens to 
look like simple scales closely imbricated. 
Phycosecis litoralis. 
P. ovata, fusca, supra squamulis minutissimis albis sat dense tecta ; antennis, mar- 
ginibus elytrorum pedibusque ochraceis, albo-setosulis, femoribus aliquando nigris ; 
corpore infra dense albo-squamoso. Long. 1} lin. 
Hab.: I George's Sound. 
In this species the punctures are filled with very minute scales, and probably in a 
fresh die the intervals between the punctures are also covered with scales ; beneath the 
scales appear to be massed together in profusion.
