quadrate mark on discoidal nervules mTich farther from extremity of 
cell. Hind-ioing : central band much narrower at its beginning on 
costa, more irregular, being broken up into mostly separate unequal 
spots ; discal row of spots also more irregular. 
$ Very much 'paUr and duller than in Bihidus, without dark costal 
"borders and with only ill-defined dusky hind-marginal borders ; no discal 
white patches^ hut a diffused very pale grey discal shade, inclining to 
whitish in hind-wing ; bluish-grey basal suffusion obsolete. Fore-win^ : 
terminal disco-cellular fuscous spot rather conspicuous, isolated, much 
smaller. Hind-wing: a more or less indistinct sub-lunulate terminal 
disco-cellular fuscous spot. Under side. — As in $ ; much duller than 
in Bihulus, the markings less distinct. Fore-tving : the discal quadrate 
marking often (in four out of eight examples) expanded into a series 
of dusky spots extending from near costa to first median nervule. 
In addition to the differences above indicated, UUrhani presents a slen- 
derer body, less densely woolly legs, and considerably longer and narrower 
wings than Bibulus. Mr. W. S. M. D'Urban, who (as noted in my work 
above quoted) first brought specimens of this form to my notice, and was dis- 
posed to regard it as a distinct species, told me that in British Kaffraria it 
appeared earlier in the year than the typical Bihulus ; and both Mrs. Barber 
and Colonel Bowker have noted its occurrence in a different station, viz., among 
long grass and low bushes. The former of these two observers wrote that the 
stronghold of this butterfly was along the coast of Bathurst District, where it 
occurred in great numbers ; and the latter found it among long dry grass on the 
Bashee Eiver, and noted that it kept on the wing for a long time together. 
I took a single 9 flitting about some bushes on the margin of the New Year's 
Kiver, in the Albany District, on loth February 1870. The geographical range 
corresponds pretty closely with that of Bihidus, but I have not seen any 
examples from any part to the north-eastward of Natal. 
I have great pleasure in naming this butterfly after Mr. W. S. M. D'Urban, 
r.L.S., Curator of the Exeter Museum, who added so much to our knowledge 
of the South-African Rhopalocera during his sojourn in British Kaffraria in 
1860-61.
