neither purpose doing this myself nor accepting Chapuis' 

 subdivisions, although probably his names will eventually be 

 maintained for restricted groups. In Blackburn's comm^ents 

 on the genus a character noted as being constant was "elytra 

 transversely wrinkled at the sides.'' Nevertheless, he referred 

 species to it whose elytral punctures are nowhere transversely 

 confluent. He also referred to it various species whose femora 

 were unarmed, or upper-surface glabrous, or prothorax with 

 sides dentate in middle; all characters at variance with the 

 original diagnosis. He also said that the sexes differed in 

 the basal ventral segment. Tliis is usually the case with the 

 larger species, but many of the smaller ones have the basal 

 segment exactly alike sexually ; they usually have the apical 

 segment more or less conspicuously impressed (usually with 

 a circular fovea) in the male, and sometimes the preceding 

 segment is impressed; but the female also occasionally hat, 

 abdominal impressions. ^69) Qn the larger species the labrum 

 IS usually conspicuously metalHc; and many 'specimens of such 

 species appear to have the upper-surface glabrous, but this is 

 nearly always due to abrasion; in the lateral gutters of the 

 elytra of such specimens there is generally to be seen a 

 remnant of the clothing. On some of the large species the 

 hind tibiae are curiously shaped at the apex in the male, but 

 they are not notched as in Tomyris, Rhy panda, etc. ; the ex- 

 cavation being on the apical slope, not before same, as on 

 those genera. On each side of the head, usually just behind 

 the clypeus, there is generally a small impunctate space, fre- 

 quently highly polished, and usually a vague depression 

 adjacent to same, but its presence or absence apears to be 

 individual rather than specific, so I have usually not men- 

 tioned it in the descriptions. The antennae are long and 

 thin and, apart from colour, of but little use in descrip- 

 tions*™); in all the new species here described, unless stated to 

 the contrary, the second joint is much shorter than the thirds 

 but the third varies from slightly shorter to slightly longer 

 than the fourth. 



In the accompanying table the sole consideration was to 

 present the species known to myself in such a way that their 

 identification might be hastened :• — 



(69) The male also usually has the abdomen conspicuouslv 

 glalu-oiis along the middle, whereas on the female it is usuallv 

 ch)thpd as the rest of the surface. 



(70) They liave, however, all been examined.
