cordate, trisulcate lengthways but sometimes bisulcate ; elytra more 

 or less rounded at the shoulders, or oblique, sutural stria entire, 

 dorsal one shortened ; abdomen a little narrower than the elytra, 

 immarginate, obtuse and abruptly declivous at apex, first dorsal 

 segment by far the largest, the others being hardly conspicuous at 

 first sight. 



This genus, which was formerly included in Batrisiis, is a very 

 distinct one, owing to the large size of the head, the position of the 

 eyes, and the first dorsal segment very much larger than all the 

 others put together. 



Numerous in the Indo-Malayan region ; few only are recorded 

 from Africa (West Coast, Gaboon, Abyssinia, East Coast). 



Bateisodes natalensis, 

 Plate XVI., fig. 20. 



Oblong, rufous, shining, covered with a short pallid pubescence ; 

 head large, quadrate, sinuate laterally, frontal part deflexed, slightly 

 raised on each side above the insertion of the antennae, transversely 

 sulcate in front, and having two large foveae nearly before the eyes, 

 which are large ; antennae elongate, third to eighth joints suboblong, 

 seventh a little longer, ninth to tenth larger, ovate, eleventh larger, 

 ovate, acuminate ; prothorax broader than the head, strongly cordate, 

 rounded laterally, trisulcate longitudinally and unisulcate trans- 

 versely, base bifoveate ; elytra large, slightly rounded laterally, 

 subconvex, shoulders oblique and obtusely dentate, dorsal stria 

 nearly straight, abbreviated before reaching the apex ; abdomen a 

 little shorter than the elytra, attenuate at apex, first dorsal segment 

 large, bi-impressed at base, median impression larger than the others, 

 transverse, broadly and deeply excavate at apex, the anterior margin 

 of the excavation is deeply bisinuate, the apical one bituberculate, 

 the bottom has a median transverse laminiform process with a 

 tubercle above it in the median part ; metasternum hardly sulcate ; 

 legs elongate, all the femora thick, slightly sinuate behind, all tibiae 

 nearly straight. Male. Length 1*20 mm. 



Hab. Natal (Frere). Three examples. 



Tribe BEYAXININI. 



Body generally short and more or less globose and convex ; 

 antennae eleven-jointed, separate at base, head generally flat, 

 trapezoid, bearing no antennal tubercles ; the maxillary palpi are 

 well developed, but never of large size, the first one concealed, as 

 usual, in the mouth, the second one more or less elongate, curved 

 and clavate at tip, the third small, globular, and triangular, fourth
