Tkibe EGINI.° 



Gen. EGA, 

 Catal., p. 146. 



The Ega natalensis, loc. cit., p. 146, must be transferred to the 

 genus Pscliphanax, Walk., Ann. and Mag. Nat. Hist., hi., 1859, 

 p. 52. 



Tbibe HELLUONINI. 



Gen. MACROCHILIA, 



Catal., p. 166. 

 Macrochilus viduatus. 



Piceous-black, shining, labrum, apical part of the palpi, the two 

 basal joints of antennae, legs and under side piceous-red ; head 

 deeply punctured, the punctures not closely set ; prothorax cordate, 

 deeply emarginate laterally in the posterior part, and with the basal 

 angles very sharp and triangular ; it is deeply pitted all over, broadly 

 depressed longitudinally in the middle, and with a very fine line in 

 the centre of the depression ; elytra parallel, narrowly striate, with 

 the intervals broad, plane, and very closely punctured ; they are 

 very briefly pubescent, and have on each side, towards the median 

 part, a medium-size, round, flavescent patch, extending from the 

 second to the sixth interval. Length 13 mm. ; width 4 mm. 



This species is differentiated from M. bi-plagiatus, Catal., p. 166, 

 by not having the elytra carinate and with a double series of 

 punctures on each carina. 



Hab. Transvaal (no exact locality).
