the clypeus is not deeply nor broadly emarginate at apex, and the 

 frontal carina is nearly transverse in the male, and more arcuate in 

 the female as well as sub-tuberculate in the median part ; palpi and 

 antennae black ; prothorax marginate laterally and in front but not 

 along the base which is not arcuate, it is very convex, without any 

 dorsal or basal median impressed line, but the anterior part is dis- 

 tinctly retuse in the large development, but only moderately so in 

 the normal one, and there is on each side of the retuse part a more 

 or less distinct sub-lateral impression not deep enough, however, to 

 make the median part appear lobate ; elytra very convex, as long as the 

 prothorax, narrowly striate, the striae punctulate and the intervals 

 plane and filled with closely set, somewhat deep punctures ; 

 pseudepipleural stria reaching to two-thirds of the length and 

 punctulate ; pygidium moderately closely punctured ; metasternum 

 nearly impunctate, mesosternum punctulate ; along the edge of the 

 outer margin of the elytra there is a more or less distinct punctulate 

 stria beginning near the ampliate part and disappearing at the 

 rounding of the apex.

Maceoderes sPECTABiiiis, n. spec. 



Female : Black, sub-opaque, antennae and palpi ferruginous 

 brown ; anterior part of the head plicate transversely, somewhat 

 roughly punctured behind the frontal carina which is a little arcuate 

 and of even height ; prothorax deeply and very closely punctured, 

 vertical in front and having on each side two impressions so deep 

 that the median part, which is sinuate transversely at tip, is almost 

 lobate, the punctures are equally distant, and there is a faint 

 impression at the base, and a faint, median, very short furrow ; 

 elytra deeply striate, with the intervals raised in the basal part, 

 rounded and sub-costate past the middle, but not tectiform, and 

 covered with closely set, irregular deep punctures, there is no trace 

 of pseudepipleural stria except near the rounded apical part, and the 

 anterior tibiae have a very distinct basal tooth above the digitation. 



The male is unknown. 



This species is easily distinguished by the retuse prothorax which 

 is almost lobate in front, and by the absence of pseudepipleural 

 stria. It is probable that the prothorax is still more lobate in the 

 male. 



Length 12f mm. ; width 8J- mm.
