the red colour covers nearly the whole hinder disk, in some 
individuals even extending upwards beyond the median line. 
2. Monolepta Cumingii. Auguste ovata, postice paullo ampliata, 
convexa, rufo flava, nitida, antennarum articulis intermediis ultimique 
apice, tibiis tarsisque nigris ; tliorace quam longo vix dimidio latiore, 
subcylindrico, disco paullo deplanato ; elytris minute punctatis, nigris, 
utrisque macula parva basali dimidioque postico sanguineis. Long. 
3 lin. 
Mas. Elytro utroque callo subhumerali, hoc medio fovea rotundata, 
profunde impresso, instructo. 
Sab. Philippine Islands, Manilla. 
Encarpse and lower face pale flavous. Antennae filiform, the 
third joint twice the length of the second ; the three lower ones 
rufo-flavous, the fourth to the seventh black ; the four outer 
joints, the black apex of the apical one excepted, white. Thorax 
nearly one half broader than long ; sides straight and very 
slightly diverging from the base to beyond the middle, thence 
slightly converging to the apex, the hinder angle acute, the 
anterior one slightly produced into an obtuse tubercle; disk 
subcylindrical, very minutely punctured, the puncturing only 
visible under a strong lens. Elytra convex, not excavated below 
the basilar space, finely and rather closely punctured. Each 
elytron in the d 1 with a large subhumeral callus, in the centre of 
which is a round fovea. 
The narrow subcylindrical thorax in both sexes will at once 
separate the present species from its allies ; the S also may be at 
once known by the small size and different shape of the elytral 
fovea. 
3. Monolepta foveicollis. Ovata, postice ampliata, convexa, 
flava, nitifla, pedibus rufo-testaceis, antennarum articulis intermediis 
nigris ; thorace transverso, disci medio transversim excavato ; elytris 
tenuiter punctatis, nigris, apice sanguineis. Long. 3f lin. 
Mas. Elytro utroque fovea magna ovata, disco externo ante medium 
posita, profunde impresso. 
Sab. Batchian ( Wallace ) : a single specimen. 
Antennae filiform, the third joint nearly one half longer than the 
second ; the fourth to the seventh black, the rest flavous. Thorax 
nearly twice as broad as long; sides obliquely diverging from 
the base to the middle, thence rounded and converging to the apex, 
apical angle produced- into a flattened obtuse tubercle; disk
