more posteriorly, the fine, soft, erect, whitish pubescence of the upper sur- 

 face a little longer and more evident. Antennae {(J^) fully attaining the 

 middle of the elytra, pale at base, blackish and distinctly serrate from 

 the fifth joint, the triangular joints strongly compressed, gradually in- 

 creasing in width to the seventh or eighth, then decreasing in width to 

 tip, the wider joints nearly as wide as long. In the female the antennae 

 are much shorter, not passing the humeral umbone, but the joints though 

 narrower are proportioned nearly as in the male. In murrayi the 

 antenna? are nearly filiform in both sexes, the outer joints (5-11) very 

 feebly serrate, mutually equal in width and nearly three times as long as 

 wide. There is the same sexual difference in length, and the outer joints 

 are blackish as in elegans. 



In the "Transactions," 1893, p. i37> Horn describes the 

 genus Glyptoscelimorpha and takes the opportunity of present- 

 ing the differential characters of the Schizopini to which the 

 genus belongs. The three genera comprising the tribe are 

 there separated as follows : 



Antennae slender, nearly filiform, scarcely at all serrate. 

 Claws entire at tip, slightly thickened at base ; last joint of antennae 

 nearly one-half shorter than the tenth . . . GlyptOSCelimorpha. 

 Claws cleft at tip, last joint of antennae very little shorter than the 



tenth Dystaxia. 



Antennae flattened, the joints 4-10 broader than long and distinctly ser- 

 rate ; claws cleft at tip ; last joint of antennae oval, longer than 

 the tenth Schizopus. 



From the above table it would appear that a mistake had 

 been made in referring elegans with its flattened serrate anten- 

 nae to Dystaxia, and that it would more properly be placed in 

 Schizopus . Mu7'rayi and elega7is are, however, too nearly iden- 

 tical in every feature of structure and facies, with this one ex- 

 ception, to warrant their assignment to distinct genera. The 

 table given by Horn must then be modified, and in so doing 

 attention should be called to an extraordinary character, which 

 somewhat curiously escaped both Le Conte and Horn. In 

 Dystaxia and also in Glyptoscelimorpha the antennae are 12- 

 jointed ; in Schizopus they are 11 -jointed, as indeed they are 

 in every other known genus of the BupreslidcE if we may de- 

 pend upon Kerremans, who so describes them without naming 

 any exceptions in his late work on the family in Wytsman's 

 Genera Insectorum. These three genera may then be more 

 properly characterized thus :
