HELICONIDZ—MECHANITIS. 
MECHANITIS MESSATIS, 4. 
Uprrrsipe. Female. Anterior wing black, with numerous spots of white ; 
from the base to the middle of the cell (except the costal margin, which is black), 
bounded by the first median nervule, and ending im a point before it reaches the 
outer margin, with a part of the costal margin, orange. ‘The spots form three irre- 
gular oblique bands across the wing ; the first band of three spots, the first of which 
crosses the cell, the third is near the anal angle; the second and third bands each 
of three spots, those near the costal margin bifid; two spots near the apex, and a 
submarginal row of six smaller spots placed in pairs. Posterior wing orange, with a 
curved band of black from the costal margin to the middle of the third median 
nervule. The outer margin broadly black, with a row of mimute indistinct white spots. 
Unpersipg, as above, with the submarginal spots continuous and much more 
distinct ; the base of the posterior wing marked with a yellow spot and a black line, 
which is united to the curved band described above. 
The male I have not seen.

This, the most beautiful species of its genus, has a considerable resemblance to Heliconia 
Ismenius of Latreille. With many more new species which we hope to publish, this formed part of 
a very fine collection of butterflies made by Mrs. Mark during a residence at Bogota. 
MECHANITIS MNASIAS, 5. 
Uprrersipr. Male. Anterior wing with a large spot at the base, and two small 
spots between it and the outer margin, touching the first median nervule, orange ; 
an oblong oblique spot across the cell; a spot below it united to a curved, broad, 
irregular, transverse band beyond the middle; light transparent yellow. Posterior 
wing orange, transparent at the base, with a longitudinal band across the middle, and 
the outer margin, black. Both wings with a submarginal row of distinct white spots. 
UnpersIDE as above, except that the orange at the base is united to and forms 
one with the two small spots described above, and that there is a band of black near 
the costal margin of the posterior wing, from the base till it is united to the central 
band.
