AKT. I) FLIES OF THE FAMILY SYRPHIDAE SHANNON 25 



oblique yellow spots directed outward and backwards. Length 7 

 mm. ; wing 5 mm. 



Chile: Santiago (A. Faz). 



ALLOGGRAPTA PULCHRA, new species 



Female. — This species is easily separated from hortensis by the 

 much less developed stripe extending from the anterior oral margin 

 to the vertex; it is suddenly narrowed at the antenna, being less 

 than one-half the width below the antenna than above; no black 

 spot on jowl; metapleura (pleurotergite) extensively yellow; the 

 yellow markings on the abdomen much larger, the spots on the second 

 tergite usually narrowly confluent; those on the third tergite con- 

 nected and forming a broad cross band which extends over the sides ; 

 the fourth and fifth tergites each with a pair of oblique spots which 

 extend over the sides. Eength 6.5 mm. ; wing 5 mm. 



Male. — Ocellar triangle aeneous black; frontal triangle entirely 

 yellow; facial stripe narrow, sometimes greatly reduced; upper eye 

 facets moderately enlarged. 



Eight males, seven females. 



Type locality.— Knglo, Chile (February 21, 1924, D. S. Bullock). 



Type.—M^\Q, Cat. No. 28745, U.S.N.M. 



A male and female (Chile, E. C. Reed) were determined by Reed 

 as h^rfensis. 



FAZIA, new genus 



Type. — Fazia hullaephora., new species. 



Belongs to the tribe Syrphini. Differs from Syrphus ribesii Lin- 

 naeus (which is considered typical of the genus Syrphus) in having 

 the oral margin anteriorly produced (figs. 7 and 8) ; the apical cross- 

 vein rather strongly recurrent (figs. 9 and 10) ; and the metasternum 

 l^ilose. This last character is found in only two other genera of the 

 Syrphinae (as far as I know), namely, Asarina, found in the Orient, 

 and C'la?'aplu7)iula. Asarina is quite distinct from Fazia. Clara- 

 plnmula is described in the preceding section of this paper. 



The antennae are widely separated in Fazia., the lower squama is 

 bare, and the sides of the abdomen are not marginated. 



The genus is named for Sr. A. Faz, of Chile. 



FAZIA BULLAEPHORA, new species 



Female. — Upper half of front including vertex dark aeneous, 

 lower half, save for a well-defined black region above antennae, 

 yellow ; entire front black pilose, width at vertex not as wide as the 

 distance between the lateral margins of the antennal pits; antennal 

 pits separated, antennae rather small, black; arista black, as long as 

 length of antenna; face yellow, yellowish brown through the middle; 

 tubercle prominent; oral margin produced in front and darkened;
