oclireous-yellow, passing posteriorilj into lake brown ; rather 

 sparingly haired ; broad-oval, base developed into a turgid 

 costa, curved sbarplj forwards ; posited immediately in. 

 front of basal end of costa, outer side, is a large, 

 conspicuous, lake-black, ere scent- shaped, sub-free pro- 

 cess. Bulbous genitalis mahogany-brown, reticulated — viewed 

 from front, sub-obovate, fore-third deeply cleft beneath 

 lamina ; a moderately long, orange-brown, linear apophysis, 

 curves over the somewhat pointed base ; most observable 

 appendages beneath bulb are two strong, black close-lying, 

 curved, spine-like apophyses, projecting from outer margin of 

 concavity transversely across bulb. 



Abdomen sub-aplanate, sides rugose, base rounded in out- 

 line ; tapers from humeral tubercles to posterior-third, which, 

 is constricted to rather less than half the greater breadth ; 

 basal margin studded with a series of six small tubercles, 

 centre pair greenish-yellow, much the largest, visibly more 

 distant from humeral tubercles than they are from each 

 other; humeral tubercles of moderate size, obtusely conical, 

 opalescent, streaked with lake ; upper side exhibits a remark- 

 able pearl-like spot ; integument developed immediately be- 

 hind humeral tubercles into sub-tubercular elevations not 

 differing very essentially either in form or colour from the 

 former ; projecting from second quarter of dorsal aspect is a 

 large backward curved process, resembling the horn of a 

 rhinoceros — about as wide at base as long; length equal to 

 more than one-fourth of abdomen; orange-ochreous, speckled 

 with red-brown, apex yellow; posterior side exhibits a yellow, 

 white-haired medial stripe, bordered with a dark edge, rising 

 from posterior third is a similar but much smaller process, 

 flanked by two pearl-like spots; hind tubercular projections 

 in two rows ; laterals longest, somewhat elongated ; directed 

 outwards, lake-brown, pale median streak ; centre tubercle 

 much the smallest of the row, obtuse-conical, tubercle of 

 second row pointed, rather wider than long, fully half length 

 of laterals ; two centre tubercles yellow, marked with red- 

 lake ; ground colour blue-black ; the pattern — which re- 

 sembles the handsome border of an Oriental shawl — is of an 

 orange colour picked out with lake, clothed with golden and 

 silver hairs ; basal cross-band occupies one-third of dorsum ; 

 fore-half of band exhibits a series of circles enclosing blue 

 spots, separated by about their own diameter ; second half 

 represents a centrally interrupted band of somewhat even 

 width, figured with blue and lake sinuate lines ; design on 

 posterior two-thirds consists of a series of intricate lines 

 enclosing two unfigured sub-oval patches, which flank the 

 larger process. 



Two male specimens.
