In the two specimens before me the flayous patch on the elytra 
varies in extent. 
31. Aulacophora antennata. Anguste ovata, postice ampliata, 
convexa, rufo-fulva, nitida ; antennis flavis, pectore rarius pedibusque 
piceis; elytris convexis, infra basin prope suturam transversim excavatis, 
nigris, tenuissime punctatis ; thorace kevi, sat profunde transversim 
sulcato. Long. 4-4| lin. 
Mas. Antennarum articulo ultimo incrassato, apice oblique sinuato- 
emarginato, dente acuto armato ; abdominis articulo anali trilobato, 
lobo interraedio transverso-quadrato, disco concavo. 
Fcem. Antennarum articulo ultimo non incrassato, abdominis segmento 
anali late truncato, obsolete sinuato. 
Yar. A. Pedibus fulvis. 
1 Tab. Java; Singapore; Borneo, Sarawak {Wallace). 
Antennae filiform, the apical joint in the male thickened, its 
apex obliquely emarginate and armed with a short acute tooth ; 
labrum and mouth concolorous with the upper face. Thorax

slightly diverging from the base to just beyond the middle, thence 
obliquely converging towards the apex, anterior angle obliquely 
truncate, armed laterally with a small obtuse tooth; upper 
surface smooth, with a few scattered punctures on either side 
behind the anterior angle ; transverse groove nearly straight, 
deeply impressed. Elytra dilated posteriorly, convex, transversely 
excavated below the basilar space, minutely but not closely 
punctured. 
32. Aulacophora luteicorhis, Fabr. 
Late ovata, postice ampliata, thorace sat profunde transversim sulcato, 
lateribus obtuse rotundatis ; elvtris tenuissime punctatis. Long. 4 lin.
