in colour from the type, the prothoracic vitta being more 

 dilated to the base and the elytra black, except that the sides 

 are pale from the shoulders (there half-way to the suture) 

 to the apex, and continued very narrowly up part of the 

 suture; its palpi are almost entirely pale. 



PSEUDOLYCUS NIGER, n. Sp. 



9 . Black, opaque. Densely pubescent. 



Head rather strongly convex between eyes ; with dense 

 and minute punctures. Antennae with third to seventh joints 

 wide, flat, and triangularly dilated to apex, eighth flat, but 

 decidedly narrower than seventh, ninth and tenth also flat 

 but decreasing in width, eleventh conspicuously semidouble 

 and slightly longer than tenth. Prothorax lightly transverse, 

 sides widest near apex : with three large excavations : a 

 medio-basal one and one towards each side in front, the latter 

 somewhat larger and deeper than the former. Elytra much 

 wider than prothorax ; each with four rather obtuse, sub- 

 costal, discal elevations ; surface partially concealed but finely 

 granulate-punctate. Length, 11 mm.

At first glance strikingly like the variety atratus, of 

 haenwrrkoidalis, but readily distinguished from that species 

 by the antennae; these have the eighth joint quite as flat as 

 the seventh and fully half its width, the ninth and tenth 

 are also flat. In haemorrhoidalis, and all its varieties, the 

 eighth-eleventh are cylindrical, and subequal in width; the 

 apical joints to a certain extent resemble those of torrid us 

 and wallacei, but the species is otherwise very different. The 

 medio-basal depression of the pronotum approaches to a 

 triangular shape, but less conspicuously so than on haemorr- 

 hoidalis, the bounding lines being less acutely elevated and not 

 so straight. The entire insect is of a deep black colour, except 

 that parts of the muzzle and of the under-surface are very 

 obscurely diluted with red. 



PSEUDOLYCUS CANALICULATUS, n. sp. 



d ■ Black ; prothorax and elytra partly red ; elytra sub- 

 opaque, elsewhere shining. Moderately clothed with short 

 pubescence, mostly similar in colour to the derm on which it 

 rests ; prothorax glabrous. 



Head moderately convex between eyes : punctures minute 

 and more or less concealed. Antennae with more or 

 less cylindrical joints. Prothorax lightly transverse, 



sides rounded on apical half, incurved on basal half : with a
