from the Rio Nautla, State of Vera Cruz. 283 
fifth seements showing more or less distinctly a slight silvery 
pollen, rest of abdomen less distinctly so. Black of abdomen 
more or less shining through the pollen. Legs black, 
proximal third or fourth of hind femora yellow ; coxe and 
trochanters reddish yellow, with the dense silvery pollen of 
pleure extending over them. Hind tibie short ciliate on 
apical half. Pulvilli and claws elongate, latter wholly blackish, 
often with tips fractured and missing, as mentioned in 7’ri- 
chopoda, pulvilli whitish or yellowish fuscous. Wings evenly 
black along whole costa to tip for about one half of their 
width, the black filling out all three basal cells, but with 
apical cell clear or a little clouded across tip. Rest of wings 
nearly clear, subhyaline, sometimes faintly tinged with dilute 
smoky. Tegule very large, white, sometimes watery whitish; 
alnlets small, about one sixth to one eighth size of tegule, 
white, sharply contrasted in colour with rest of wing. 
Female.—Difters in face and orbits being entirely silvery 
white, not golden. Abdomen slightly less broad; abdominal 
spots more narrowed oblique, not so extensive on dorsum of 
third segment, not notched on inside, thus leaving the median 
black evenly and rapidly widened posteriorly from its least 
width at or behind middle of second segment; fourth and 
fifth segments more distinctly silvery pollinose, rather con- 
spicuously so in comparison with the males. One male, 
however, has the abdominal markings and pollen almost as 
in the female. Claws and pulvilli very short. Sixth 
abdominal segment much less apparent. 
Phania simillima, Fabr., Wied., apparently belongs to the 
subgenus Pennapoda, and is thus nearly allied to the present 
species. Its greater size (about 10 millim.), the reddish- 
brown instead of pale yellow abdominal spots, and the reddish- 
brown bases of femora and hind tibie preclude the identifica- 
tion with it of the present form.

One female. San Rafael, March 9. 
Length 5 millim. 
This specimen is perfectly normal, except that the pollen 
of mesonotum and front has a brassy tinge, and the silvery 
fascia is present on second segment of abdomen. Apical cell 
extremely short, petiolate. 
In the first section of this paper I recorded a male specimen 
of C. immaculata, Macq. (No. 16). I must again, for the 
last time, correct my statement on the synonymy of these 
species. ‘The remarks there should read as follows :—The
