the striae geminate and punctured, intervals closely and deeply 

 punctured ; pygidium closely pitted, and nearly glabrous or very 

 briefly pubescent ; metasternum deeply impressed at base, and 

 finely aciculate in the centre. 



Male : Gense projecting a little more than in the female, and a 

 little more angular, clypeus straight laterally from the gense, then 

 produced obliquely and with the apical part raised as a vertical, 

 sub-quadrate laminate tooth (fig. 4) ; prothorax sharply declivous in 

 the anterior part and having in the centre a vertical lobe distinctly 

 impressed on either side and surmounted by two sharp tubercles 

 united by a strongly arcuate carina, the two tubercles curve 

 slightly backwards, and in the centre of the declivity there is a fine 

 median, smooth line. 



Female : The clypeus is nearly rounded in the anterior part from 

 the anterior angle of the genae, and is slightly sinuate at apex ; the 

 genae do not project quite so much as in the male; the prothorax 

 is convex, not declivous at apex, and has there two rudimentary 

 tubercles connected by an almost obsolete arcuate ridge, and the 

 head has a transverse truncate carina vertical. 



Length 10-12 mm. ; width 6-7 mm. 



Hah. Southern Ehodesia (between the Limpopo and the Zambeze 

 Bivers, Victoria Falls). 



It occurs also in Nyassaland. 



Phalops rufo-signatus, Lansb., 

 Notes from the Leyden Museum, 1885, p. 19. 



** In my monograph of the genus Phalops (Stett. Ent. Zeit., 1883,. 

 p. 168), I have mentioned a species already noticed by Baron von 

 Harold, w^hich neither he nor I had ventured to describe, because 

 the female only was known. Later on I met with the male in 

 the collection of the Leyden Museum, and I can therefore describe 

 it now. It belongs to that division in which the metathorax has 

 no median impression (fossette). 



Bronze black, with the head and prothorax somewhat greenish ; 

 under side and legs black, shining, elytra with rufous maculae. 



Male : Head ogival with the clypeus acuminate, but reflexed at 

 the apex into a rounded tooth ciliate inwardly, vertex armed with 

 a bifid lamina the tips of which are smooth ; the surface of the head 

 is covered with a squamiform granulation, and the genae do not 

 project ; prothorax convex, densely granulose, and clothed with 

 short greyish hairs, it is excavate in front, has a longitudinal shallow
