I wish to thank Dr. Darlington and Dr. Bequaert for 
the opportunity to study the Syrphid material of the 
Museum of Comparative Zoology. This new species is in 
the Museum collections. 
Mallota bequaerti, n. sp. 
A large species characterized by dense yellow pile on 
mesonotum and scutellum. The abdomen is entirely short, 
densely black setate, with the exception of the fourth 
segment which is short, golden red, appressed setate. 
This species is very distinct from other forms, including 
facialis Hunter, var. flavoterminata Jones, because of the 
presence of the large, distinct, subquadrate, dark brown 
spots on the middle of the wing and the presence of the 
rather widely separated eyes of the male. Length, about 
16 mm. 
Male. Head : eyes bare, the vertex is convex and shin- 
ing black with black pile; the ocelli lie in an equilateral 
triangle. The lateral margins of the vertical triangle, 
anterior and lateral to the ocelli, are striate. The eyes 
are separated by a distance at least equal to the space 
between the posterior ocelli. The front is shining black 
broadly down the middle and in front of the antennae, 
with the sides rather thickly dusted with pale yellowish 
pollen, which becomes more brownish medially; this leaves 
approximately the middle two-thirds of the front shining 
and bare, with the ground color black. The face is black, 
with a broad, shining, bare, medial stripe, its sides widely, 
silvery white mieropubescent; pile of the face and front
