we were told that there had been some nice showers at night during 
March. The Trade-wind blows very strongly along the coast, a dry, 
hot blast which greatly increases the difficulties of the collector. 
Cocoa Wattie is a plantation near the middle of the island towards 
the confines of cultivation, lying about 550 ft. above sea-level. The 
wooded banks of a small river and some swampy hollows clothed 
with coarse grass and thin scrub afforded the best collecting grounds, 
and yielded, as might have been expected, a somewhat different 
fauna from that of the coast. It rained heavily on April 8th. 
Anosia archippus, Fabr. (plexippus, auct. nec Linn.). Three one $. 
Bather common in the outskirts of Scarborough; one specimen at 
Cocoa Wattie. My specimens resemble those from the mainland, 
though one Tobagan, a <J, approached Jamaican specimens in colouring. 
Euptychia hermes, Fabr. (camerta, Cram.). Five. Abundant at 
Cocoa Wattie. 
Euptychia hesione, Sulz. Six. Common at Cocoa Wattie. 
I have taken this species and the following flying during rain. 
Heliconius hydarus hydancs, Hew. Three <J, two $. Bather 
common on the river bank at Cocoa Wattie. All the specimens are 
small, three extremely so; four of them have the bluish gloss (as 
in the form guarica, Beak., though that is a larger insect) which 
Mr. W. J. Kaye associates with wet conditions. 1 
Precis lavinia, Cram., f. zonalis , Feld. Two <J. An example taken 
near the coast of the “ dry ” form, but with the anterior ocellus on the 
hind-wing very small. (Mr. W. J. Kaye has two very dark specimens 
from Mexico in which this ocellus is altogether wanting; in the 
National Collection there is a specimen from Colombia in which 
there are no ocelli on the upper surface, and only faint indications 
of them beneath.) The Cocoa Wattie example is intermediate, 
approaching the wet-season form. Both the specimens would probably 
be called by Mr. Godman coenia, Hubn., and by West Indian 
entomologists genoveva , Cram.; but I follow Mr. G. A. K. Marshall. 2 
Anartia jatrophae, Linn. Three. On the coast, not common. 
Those taken are pale in colour and semi-transparent, of the main¬ 
land form. 
Anartia amalthea , Linn. One at Cocoa Wattie. Messrs. God- 
man and Salvin 3 say of this species : “ Barbados, a single specimen 
. . . not previously noted from any West Indian island.”
