1905] CLARK— HITTER FLIES OF CEEE'.ZUEL.A 7 
Amphichlora ferentina (ioclt. [Plate I. fig. 2.] 
Common in the cocoanut groves about K 1 Valle. When flying it occasionally 
produces the clicking sound so characteristic of the group, and it always alights 
head down. When alarmed, it seldom goes far, often only to the next tree. Its 
flight is, as a rule, low, rather swift, and in a straight line, reminding one of the 
flight of Arpynnis lathimia or of Euptn/eta clauiiia, but is more hurried than that 
of either of these. 
■Specimens from Margarita differ from the continental examples which I have 
examined in being uniformly smaller, with a greater amount of white in the ground 
color of the wings, particularly of the secondaries. 
Amphichlora poseidon, new species. [Plate i. fig. i.] 
Type locality, K 1 Valle, Island of Margarita, Venezuela. 
Expanse, 2.6 in. 
General ground color of the secondaries and basal third of primaries, a uni- 
form pale dusty bluish gray, with reflections of reddish bronze. 
Primaries. Outside of a crenulate line beginning two-thirds of the distance 
from the base of the wings to the end of the cell, and extending in a direction 
almost at right angles to the costal margin to a point one-quarter of an inch 
from the outer edge of the wing, on the posterior border, chalky white, with a 
narrow line of gray in the cell near its distal extremity, and a wavy gray line par- 
allel to the outer border of the wing, beginning a quarter of an inch from the distal 
end of its inferior margin, and extending to the vein passing from the middle of 
the distal end of the cell to the edge of the wing, then turning and running to the 
costal margin in a direction at right angles to it. The distal border of the pri- 
mary is light gray, interrupted in seven places by white streaks, the sixth from 
the apex being almost as wide as the distance apart of the veins between which 
it occurs, just inside this border is a row of five white spots, .separated from the 
general ground color by irregular borders of light bluish gray. The first two of 
these spots are small, and are situated at the apex of the wing; the third, which is 
larger, is separated from the second by two veins. The fourth, which is the 
largest of all, is separated from the third by one vein, and the fifth, which is 
small, is one vein beyond the fourth. Midway between the two apical spots and 
the wavy line mentioned above, there is a patch of light gray, which extends as 
far as the second vein from the costal margin. The part of the wing proximal to
