230 Mr. R. McLachlan on the 
pressed line, fringed with a long and thick crest of cinereous 
hairs. 
Thorax deep opaque black above, clothed with cinereous 
hairs ; an oval antehumeral isolated yellow spot on each side 
anteriorly, scarcely touching the. anterior margin, and a trans- 
verse cuneiform yellow spot on each side posteriorly, margining 
the thoracic cavities, which are also yellow; interalar space 
spotted with yellow. Stdes of thorax metallic green, with 
seven large yellow spots arranged in two series (three and 
four); posterior margin also yellow; pectus spotted with 
yellow. 
Legs deep black (brownish in a somewhat immature ex- 
ample), long and slender ; femora with only short spines, but 
with very long cinereous hairs; tibie with long and close 
slender spines; inner tooth of claws rather strong, placed not 
far below the apex. 
Abdomen slender, greatly dilated at the base to the end of 
the third segment ; second and third segments with a median 
suture. Colour bronzy black ; second segment with a large 
median posterior brownish-yellow spot, divided anteriorly, 
third with a large median dorsal band of the same colour (in 
the male these dorsal markings are continuous with the pale 
sides, so that almost the entire segments are pale; in the fe- 
male the dorsal markings and pale sides are separated by the 
black ground-colour) ; a small anterior brownish-yellow gemi- 
nate spot on the fourth to sixth ; on the seventh this spot en- 
larges and occupies nearly the whole of the dorsal portion of the 
seement, and on the eighth becomes small again, forming two 
small anterior lines (very indistinct in the male) ; ninth with 
two indistinct anterior points (obliterated in the male), and 
there is a small marginal point on the tenth. 
¢. Genitalia of second segment concealed, but the side- 
pieces are long, obtuse, and finger-shaped, with a tuft of long 
cinereous hairs. Superior appendages as long as the last two 
-seements, black, cylindrical, gently curved, the apical portion 
gently dilated, the apex oblique, very acute, and turned 
slightly upward ; on the lower edge is a series of about eight 
small teeth or tubercles, Inferior appendage elongate-trian- 
gular, extending beyond the teeth of the superior, its apex 
emarginate with acute angles. 
@. Appendages not so long as the nimth segment, black, 
straight, cylindrical, somewhat dilated towards the apex, 
which is acute and prolonged; the inflated ventral tubercle 
densely clothed with cinereous hairs. Vulvar scale adpressed, 
flat, longer than the ninth segment, its apex semicircular and 
slightly outstanding.
