WEST INDIES AND SOUTH AMERICA 
By nomine theseus , Feld. This pretty little butterfly was common 
both on the coast and inland. It has a rapid gliding flight, but 
otherwise has some of the habits of a Lycaenid ; thus, it often settles 
with its head downwards, and more than once I saw it immediately 
after settling move its hind-wings rapidly; the insect was, how¬ 
ever, too shy to enable me to make out the exact nature of this 
movement. 
Cystineura cana , Erichs. Two specimens on the coast, and two 
at Cocoa Wattie. It has a gliding flight. 
Zeptotes cassius , Cram. Two <$, two $. Of the mainland form, in 
which white prevails over blue. Rather common along the coast; 
three specimens were small, but one female was larger than usual. 
Catochrysops hanno , Stoll. One specimen to the east of Scar¬ 
borough. 
Theda beon , Cram. Four. One specimen on the shore to the 
south-west of the town at the flowers of the Seaside Grape; rather 
common at Cocoa Wattie, frequenting the flowers of a purple 
Papilionaceous shrub. 
Theda politus , H. H. Druce. A $ at Cocoa Wattie. 
Mr. H. H. Druce says that hitherto this species has been wrongly 
identified with T. beon, Cram. 1 To one of my specimens in the 
Hope Collection he has appended a note: “ Some ££ of T. politus 
have blue scales on the hind-wings above, which I have not noticed 
on the only I have from Santarem.” 
Theda nubes , sp. nov . 2 One specimen at the Seaside Grape, near 
Hillsborough ; four at Cocoa Wattie at the pink flowers of a creeper. 
[Plate III., Figs. 3, 4, 5.] 
Callicista bubastus, Cram, (salona, Hiibn.). One taken in Fort 
George, another at the flowers of the Seaside Grape, near Hills¬ 
borough on the coast. 
Terias nise, Cram. Three <$, three $, all of the wet-season form. 
Common near the coast. The male had a very strong scent like 
Convolvulus arvensis. 
Terias albula, Cram. Three. Near the coast, less common than 
the last; one taken two miles inland on the road to Cocoa Wattie. 
Pieris phileta, Fabr. (monuste, auct. nee Linn.). Two males under 
the coco-nut palms to the west of the town; one “ wet ” the other 
intermediate in phase. 
Callidryas eubule, Linn., f. sennae, Linn. Abundant alike in 
1 Proc. Zool. Soc. Lond ., 1907, pp. 625, 626. 
2 Described by H. H. Druce, Proc. Zool. Soc. Lond., 1907, p. 625. Mr. Druce 
received the specimens too late for figuring.
