Odontalgus longicorxis. 



This new species is very closely allied to 0. vespertinus, Kafir, 

 (see Catal., p. 105), and differs by the following points : — 



Colour a little lighter, being ferruginous with the disk of the 

 elytra more or less reddish ; head much more constricted in front, 

 which makes the antennal tubercle appear much more prominent ; 

 antennae more slender and more elongate in both sexes ; dorsal 

 segments of the abdomen neither carinate nor tuberculate on the 

 apical edge. 



Male : Antennae — joints first and second larger than the following 

 ones, second a little longer than broad, third longer than second, 

 obconical, four to seven decreasing in length, so that the fourth is a 

 little shorter than the third, seventh quadrate, eighth very trans- 

 verse, ninth cylindrical, as long as the three preceding ones, broader, 

 tenth cylindric, a trifle shorter and thicker, eleventh sub-cylindric, 

 much longer and thicker than ninth, obtuse at tip ; metasternum 

 simply longitudinally sulcated, this sulcus filled up with whitish 

 glandular pubescence, on each side, about at the middle, a short and 

 carinate tubercle ; ventral segments hardly longitudinally impressed. 



Female : Antennae — joints three to seven longer than in the male, 

 the seventh being longer than broad, eighth but little transverse, 

 ninth little larger, quadrate, tenth nearly twice larger than ninth, 

 quadrate, eleventh nearly as long as the two preceding ones, 

 broader, sub-cylindric, somewhat rounded at the base, obtuse at tip. 



This species resembles more tuberculatus , Kafir., from Abyssinia, 

 than vesper tinus, but the colour is a little darker, the club of the 

 antennae in the male is much longer, and the longitudinal channel 

 of the metasternum is complete and simple, whilst in tuberculatus it 

 is divided in two parts by a transverse carina.

PSELAPHOCERUS NODICORNIS, n. Sp. 



Ferruginous, disk of the elytra reddish, palpi testaceous, with a 

 dense, long and rufous pubescence ; head about twice longer than 

 broad, hardly narrowed in front, the anterior edge is a little depressed 

 in the middle, between the eyes, on the front part are two large 

 grooves ; eyes very large, situated beyond the middle ; first joint of 

 maxillary palpi rather long and conspicuous, cylindrical, second 

 strongly and triangularly enlarged from the base to the apex, the 

 external side rounded, and the external angle bearing on the upper
