genus. M. Fairmaire has described some species as to be 
attributed to Zaius, from Madagascar, Nossi Bé. J have not seen 
them, but I suspect it will be found that there are such radical 
differences as to preclude such an association; and he does not 
mention enlarged joints. Zaius, it may be observed, was founded 
upon a female example from Australia, and ought strictly to be 
suppressed for Westwood’s name MJegadeuterus, which at least 
expresses the fact that the second joint of the antenne is enlarged 
in the male sex. That he cluded other insects in his genus is no- 
reason for suppressing the name, but only for confining it to the 
type, and to such as can be associated with it. 
H&DONISTES LATUS, Sp. Nn. 
Brevis, niger, pube brevi cinerea erecta vestitus, valde punctatus ; 
elytris subquadratis, grosse et confluenter punctatis, fascia lata, 
ad marginem latissima, apiceque lete sanguineis ; epistomate, 
labro ad apicem et antennaruwm basi rufis. Long. 4°5—-5 
millim. 3 Q. 
Mas, capite eroso-excavato, ad antennarum basin utrinque 
carinato elevato, basi triangulariter elevato, elevatione in medio 
sulcata, antice ciliata, bicirrosa ; antennarum articulis basal 
quinto et sexto wmpliatis. 
Femina, jfronte plana, antennis simplicibus. 
Hab. Willowmore, Cape Colony (Lrauis). 
Head and thorax black, thickly and the latter rather coarsely 
punctured; the antennz have four joints at the base red, the rest 
black, the apical joint is elongate, the intermediate joints in the 
male are longer than wide, in the female about as long as wide, 
not serrate but rather triangular. The thorax is shining, not 
wider than the head, and much narrower than the elytra at the 
base, somewhat cordate, with the margins a little reflexed. The 
elytra are blue-black, with a fascia which is interrupted at the 
suture, but very broad on the margin, of a fine blood-red, and 
their apex is rather broadly margined with the same colour; the 
basal side of the fascia is produced along the margin so as to 
surround the shoulder; their surface is uniformly, coarsely, and 
in places confluently punctured, honeycombed. The legs are 
black. 
Hight examples, consisting equally of each sex, were sent me 
by Dr. H. Brauns, by whom they were obtained at Willowmore 
in Cape Colony.

Excepting that the brownish-yellow colour is more diffused in 
two examples from Bothaville, so that one is wholly brown with 
darker striz, and the other has a not very well-defined yellow
