four very conspicuous tubercles and even some indication of a fifth still nearer to 
the apex.

Z. palmetisiSy sp. nov. (2). Ovalis; minus nitidus ; piceo-niger, squamis griseis 
et cervinis intermixtis vestitus; rostro supra in medio longitudinaliter carinato et 
utrinque leviter sulcato, inter oculos obsolete impresso, scrobibus (fere ut Z. irilmli, 
Fab.) sinuatis bene determinatis; prothorace transversim subquadrato, antice 
minus angustato, crebre punctulato et sparsim imequali, canaliculate (canali antice 
vix abbreviate, ut fovea elongata terminato), lateribus leviter arcuatis mox ante 
basin sinuatis (latitudine majori ad medium posita) angulis posticis (superne visis) 
rectis suliclentiformibus; elytris striatis (striis crasse punctulatis), interstitiis alternis 
distincte elevatis et tuberculatis (tuberculis subobsoletis, tribus subapicalibus 
exceptis, horum uno in interstitio suturali uno in interstitio 3° uno in interstitio 
5° positis), angulis humeralibus subrectis ; metasterno postice baud tuberculato. 
Long. 6 1. Lat. 2i 1. 
An inconspicuous-looking species with no very strongly-marked characters. 
I should judge that a perfectly fresh specimen would be rather densely clothed 
with grey scales, some light brown ones intermingled. The alternate elytral 
interstices are only gently elevated and are obscurely knobby rather than distinctly 
tuberculate, except in having three well-defined conical but not large (that on the 
third interstice the lai’gest) tubercles towards the apex. The tubercles of the third 
and fifth interstice are at the summit of the posterior declivity, that of the sutural 
interstice further back and close to its fellow of the other elyti'on. The antennae 
are stout, the joints of the funiculus transverse and not diftering much in length 
infer se.

Z. Hor^ii, sp. nov. (3). Sat breviter ovalis; minus nitidus; piceo-niger, 
squamis albidis vestitus; rostro ut Z. pahnensis sed capite inter oculos profuncle 
foveolato; prothorace sat transverse, antice fortiter angustato, crassissime 
vermiculato-ruguloso, late minus distincte canaliculate (canali antice ut fovea 
dilatato), lateribus sat fortiter rotundatis mox ante basin sinuatis (latitudine 
majori vix ante medium posita), angulis posticis (superne visis) rectis subdenti- 
formibus ; elytris sat crasse punctulato-striatis, interstitiis alternis obsolete alternis 
magis distincte tuberculatis, tuberculis a basi retrorsum in magnitudine ci’escen- 
tibus, angulis humeralibus subacutis antrorsum vix pi’oniinentibus; metasterno 
postice baud tuberculato. Long. 1. Lat. 2'i 1.
