quadrate mark on discoidal nervules much farther from extremity of 

 cell. Eind-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 paler and duller than in Bibidus, xvithont dark costal 

 borders and with only ill-defined dusky hind-marginal horders ; no discal 

 white patches, hut a diffused very pale grey discal shade, inclining to 

 ivhitish in hind-ioing ; bluish-grey basal suffusion obsolete. Fore-iving : 

 terminal disco-cellular fuscous spot rather conspicuous, isolated, much 

 smaller. Hind-vnng : a more or less indistinct sub-lunulate terminal 

 disco-cellular fuscous spot. Undek side. — As in ^ ; much duller than 

 in Bihulus, the markings less distinct. Fore-wing : 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, UTJrhani presents a slen- 

 derer body, less densely woolly legs, and considerably longer and narrower 

 wings than Bihulus. 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 River, and noted that it kept on the wing for a long time together. 

 I took a single $ flitting about some bushes on the margin of the New Year's 

 River, in the Albany District, on loth February 1870. The geographical range 

 corresponds pretty closely with that of Bihulus, 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 Bhopalocera during his sojourn in British Kaffraria in 

 1860-61.
