Volucella abdominalis Wiedemann. Three specimens of this 
conspicuous species have been received from Cuba, a female from 
Holguin and a pair from Boniato. The large size, the uniform 
blue-black abdomen, yellow scutellum and face and plain black 
cheeks characterize it. Length 1 (j mm. 
Volucella azurea Philippi. A brilliant green species, wings 
clear hyaline with a conspicuous dark spot at the stigma. Length 
13 mm. One female from Santiago, Chile. 
Volucella boliviana n. sp. Body dark colored, front and face 
prominent making the head appear unusually large, wings hyaline. 
Length 12 mm. Front and face wide, pale yellowish green; front 
tumid, antenna? rather small, reddish; face concave beneath the 
antennae, quite prominent above the oral margin; eyes pilose, 
pilosity of the face and front largely dark colored. Thorax, 
dark, scutellum paler, legs black with the exception of the bases of 
all the tibiae which are red, wings hyaline. Abdomen dark with 
mostly dark hair, some tufts of white hair on the outer margins 
of each segment behind the incisures. 
Type female from La Paz, Bolivia. Also a female from 
Arequipa, Peru. 
At first glance this species much resembles a Gdniops of the 
family Tachinidae, but it has all the structure characters of Volu¬ 
cella. 
Volucella dichroica Giglio-Tos. Entirely purplish-green with 
unevenly infuscated wings. Length close to 10 mm. A male 
from Los Amates. Guatemala. 
Volucella esuriens Fabricius. A large violet colored species 
with the base of the wing distinctly brown before. The species 
is widely distributed and has many synonyms. Length l(i mm. 
Taken at Santa Lucia, Guatemala. 
Volucella eugenia Williston. A specimen from Boniato, Cuba 
seems to be this species. Face and front pale, cheeks black, thorax 
dark on the disk, sides and scutellum pale. A row of p rescut ell ar 
bristles and another row at the apex of the scutellum. Wings 
nearly hyaline, crossveins narrowly margined with fuscus. Legs 
dark, tibiae partially pale. Abdomen black with yellow on sides 
of first and second segments. Length 13 mm. 
I have made this identification with some hesitation mainly on 
account of the yellow at base of abdomen which Williston does not 
mention in his description. 
Volucella guianica n. sp. Length 7 mm., entire body shining 
dark green, antenna? and face, including the cheeks, yellow, wings 
with dark markings. 
Face strongly produced forward and downward, tubercle 
prominent, front brown below, black at vertex. Thorax including 
scutellum dark green, a row of spines at the apex of the scutellum
