306 Mr. J. S. Baly's notes on 



twice as broad as long ; sides nearly straight and slightly diverging 

 from the base to beyond the middle, thence obliquely converging 

 and slightly rounded towards the apex ; upper surface distinctly 

 punctured on either side in front ; discoidal groove deeply impressed, 

 obsoletely sinuate on its middle third. Elytra narrowly oblong, 

 dilated posteriorly, convex, not depressed below the basilar space, 

 very minutely punctured. 



The tooth at the apex of the pygidium will separate 

 this species from its allies. 



Aulacophora apicicornis. 



Ovata, postice amphata, convexa, rufa, subtus rufo-fiilva, nitida, 

 antennis flavis ; thorace profunde transversim sulcato ; pedibus 

 elytrisque nigris, his infra basin transversim depressis, tenuiter 

 punctatis. 



Mas. — Antennarum articulo ultimo ampliato, ovali, apice acute, 

 integro abdominis segmento anali trilobato, lobo intermedio con- 

 cavo. 



FcEM. — Abdominis segmento anali apice trisinuato. Long.

Hub. Sumatra. 



Labrum concolorous with the upper face ; antennae filiform, 

 four-fifths the length of the body in the ? , rather shorter in the ^ , 

 the apical joint in this latter sex compressed and dUated, ovate, 

 its apex acute ; the basal joint piceo-fulvous, the extreme apex of 

 the terminal joint nigro-piceous. Thorax twice as broad as long ; 

 sides straight and parallel from the base to beyond the middle, 

 thence obliquely converging towards the apex, the anterior angles 

 slightly thickened ; disk deeply impressed immediately behind the 

 middle with a nearly straight transverse sulcation ; surface shining, 

 finely punctured on either side in front. Elytra broadly ovate, 

 convex, distuictly depressed transversely below the basilar space, 

 minutely punctured. 



The entire apical joint of the antennsB in the ^ will 

 separate this species from the same sex of antennata; 

 the trilobate apical segment of the abdomen in the other 

 sex distinguishes it from its congeners with black elytra. 



Aulacophora diver sa, 

 Ovata, postice ampliata, convexa, rufo-fulva, nitida, antennis 

 flavis ; labro, elytris, tibiis tarsisque nigris ; thorace sat profunde 

 transversim sulcato ; elytris infra basin transversim impressis, 

 tenuiter punctatis.
