672 Dr. H. Bischoff: 
short depressed silvery pubescence sparsely, and, more thickly than 
the head, with black hairs; the basal half of metapleurae thickly covered 
with depressed silvery pubescence; the apex of the abdominal petiole 
from the top of the basal slops’ covered with silvery pile, the sloping 
basal part, above and below, with long black hair; on the base of the 
2nd segment, in the centre, is a pyrıform spot (the narrowed end at 
the base) of silvery pubescence, on its apex are four larger spots of 
similar pubescence, the central 2 round, the lateral larger and oval, 
extending beyond the base and apex of the central; there is a small 
spot, longer than wide of the centre of the 4th, and a large wide, trans- 
verse one across the central part of the öth; the dorsal segments are 
somewhat thickly covered with black hairs, the ventral are fringed 
with long white hairs. Legs densely covered with depressed silvery 
pile; the spurs and tarsal spines black. Thorax almost transverse 
at the base; with the sides broadly rounded; its apex above bluntly 
rounded; there is a stout, bluntly rounded tuberele on the sides above 
before the middle. 
Longth 14 mm. 
Meru low lands, Ngare na nyuki, January. 
Head clearly narrower than the thorax, very transverse behind, 
margined above; the temples shorter a little than the eyes. Antennal 
scape strongly punctured and covered with longish white hair; the 
flagellum with a mieroscopic pale down; its 2nd joint about one fourth 
longer than 'the next; it is longitudinally reticulated punctured; the 
longitudinal reticulations longer below. Thorax fully twice longer 
than wide; its becomer gradually, slightly, but distinetly narrowed 
from the lateral tooth; the apex has a steeply, oblique slope; its sides 
stoutly serrated. The sculpture of the pleurae is hid by the pubescence. 
Abdomen wider and longer than the thorax; the 2nd segment is broadly 
rounded at the base, and becomes slightly narrowed towards the 
apex. Pygidium clearly defined, the lateral bordering keels distinetly 
raised and separated; the central part is closely, longitudinally reti- 
culated. The keel on 1st ventral is obliquely narrowed upwards from 
shortly beyond the middle; the basal part has a straight edge; the 
base of the 2nd projects obliquely sharply downwards, and forms 
with the apex of the 1st atriangular ıncision; there is no keel on it; the 
Ist is broad at the base, with tooth-like lateral angles; the segment 
does not become much widened towards the apex. 
D. mephitis Sm. is a smaller species than this; is had the thorax 
red above, and it becomes gradually narrowed from the base towards 
the apex, which is not the case with bascherta, its head is narrower 
compared with the thorax, the second abdominal segment longer 
compared with the width at the base, and narrower compared with 
the width at the thorax, the abdominal hair marks are distinetly tinged 
with yellow or fulvous, not clear white, and altogether it is a more 
slenderly built species.‘
