182 - THE ENTOMOLOGIST. 



This form appears to be intermediate between M. kicetas 

 hrannea and M. madeira, Haensch.. from Manicor6 and L. Ma- 

 deira. 



3. Mechanitis visenda elevata, ssp. nov. 



^ 9 • Ground-colour of both wings darker than in typical 

 visenda. The black markings of fore wing except apical patch con- 

 siderably extended but not confluent, causing the constriction of the 

 postcellular yellow transverse band, which is characterised by its 

 tooth-like projection between veins 5 and 6 as in M. fallax, Butler. 



Allianca, Canutama, Rio Purus, September, 1913 ; also occurs 

 at Ega and Fonteboa, Upper Amazons. 



Butler's type of M. visenda came from Trovador on the 

 R. Tapajos. This race appears to be its representative on the 

 upper reaches of the Amazon and its tributaries. 



4. Mechanitis egcensis contracta. ssp. nov. 



^ 9 • Differs from typical M. egcensis, Bates, in the fore wing in 

 the absence of the fulvous subapical suffusion and in the clearly defined 

 subapical short yellow transverse band ; in the hind wing in having the 

 median black band clearly differentiated and nearly parallel-sided, 

 the marginal black border very narrow. Below there are traces on 

 the fore wing of the brown subapical suffusion, and the hind- wing 

 median band tapers proximally more decidedly. 



Allianca, Canutama, Rio Purus, October, 1913. 



5. Ceratinia ivickhami, sp. nov. 



(J . Ground-colour chocolate brown. Fore wing with black 

 markings on inner margin, between veins 2 and 3 below cell, in basal 

 two-thirds of cell and on cell-end, all very heavy. The transverse post- 

 cellular band is bright yellow and divided into three parts by the 

 junction of the marginal blaCk border with the lower black spot at 

 cell-end, i. e. it is made up of a narrow zigzag band extending from 

 just beneath the costa to midway between veins 4 and 5 half-way 

 between cell and hind margin, a small irregular spot close to the cell 

 from above vein 4 to vein 3, and a larger oval spot distally from this 

 extending slightly below vein 3. There is a small indistinct brownish 

 subapical spot and some yellow scaling anteriorly in the brown mark- 

 ing in the cell. Hind wing with fairly broad plain median band, 

 margins very narrowly black. Underside similar, both wings with 

 small and rather indistinct submarginal white spots, fore wing with 

 slight subapical chocolate-brown suffusion. 



9 . Similar, ground-colour rather lighter, fore-wing transverse 

 postcellular band divided into halves only. Hind-wing median band 

 less clearly defined. 



(? . Allianca, Canutama, Rio Purus, September, 1913 ; 

 ? . Bocca de Acre, Rio Purus, December, 1913. 



The species shows considerable variation. It shows consider- 

 able tendency to C. nianaos, Bates, whilst the fore-wing transverse 

 band has the marked distal projections of C. viola, Hsensch.
