Volucella abdominalis Wiedemann. Three specimens of this 

 conspicuous species have been recei\'ed from Cuba, a female from 

 Holguin and a pair froni B'^miato. The large size, the unifomi 

 l^lue-black abdomen, yellow scutellum and face and plain black 

 cheeks characterize it. Length Hi mm. 



Volucella azurea Philipi^i. A brilliant green species, wings 

 clear hyaline with a cons])icuons dark spot at the stigma. Length 

 1.'^ mm. One female from Santiago, Chile. 



Volucella boliviana n. sp. Body dark colored, front and face 

 prominent making the head api^x^ar unusually large, wings hyaline. 

 Length 12 mm. Front and face wide, pale \'cllowish green; front 

 tumid, antenna' rather small, reddish; face concave beneath the 

 antenna?, quite prominent above the oral margin; eyes pilose. 

 ]Mlosity 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 incisiu^es. 



Type female from La Paz, Bolivia. Also a female from 

 Arequipa, Peru. 



At fir.st glance this species much resembles a Goniops of the 

 famih' Tachinidae, l^ut it has all the structure characters of Volu- 

 cella. 



Volucella dichroica Giglio-Tos. Entirely piu"plish-green with 

 unevenh^ infuscated wings. Length close to 10 mm. A male 

 from Los Amates, Guatemala. 



Volucella esuriens Fabrieius. A large violet colored species 

 with the base of the Vv^ng distinctly brown before. The species 

 is widely distributed and has many synonyms. Length IH mm. 

 Taken at Santa Lucia, Guatemala. 



Volucella eugenia Williston. A specimen from Boniat;:), Cuba 

 seems to be this species. Face and front pale, cheeks black, thorax 

 dark on the disk, sides and scuteUum pale. A row of prescutcllar 

 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 \-ellow 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 Ixise 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 i^roduced 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
