similar palsearctic species, and especially to A. fiauescens Wood, 
from which it differs at once in having the fourth abdominal 
segment of normal size in the female. From all the members of 
this group it may be separated by the presence of the second 
series of setse on the hind tibia. 
Mallochina sauteii sp. nov. 
d'. Length 1.0 mm. Black, slightly brownish on the 
pleurae and the sides of the mesonotum in front; legs brownish 
yellow, the hind pair considerably darker; palpi pale yellow; 
antennae brownish basally, but black at tips; dorsal lamella of 
l^ypopygium fuscous. Wings hyaline, heavy veins dark brown, 
light veins very delicate; halteres piceous. Front quadrate or 
slightly higher than broad, with three transverse rows of four 
bristles each and four post-antennal bristles. Upper post- 
antennals occupying one-third the width of the front; lower 
ones smaller and closer together; bristles of lower reclinate row 
forming a pair at each lower angle of the front, the inner one on 
a level with the upper post-antennal and almost directly below 
the outer bristle, although not quite so close to the eye; upper 
row slightly curved downwards medially, its bristles equidistant; 
ocellar row as usual; ocellar tubercle and median frontal groove 
present. Antennae of moderate size; arista nearly bare, as long 
as the head-height. Palpi small, with the usual bristles of mod- 
erate size; cheeks each with a pair of very large bristles. Meso- 
notum distinctly shining, with one pair of small, widely separated 
dorsocentral bristles close to the posterior margin. Scutellum 
twice as broad as long with a single pair of very long bristles. 
Propleura with two minute bristles just above the coxa; meso- 
pleura hairy above, with one or two small bristles at the lower 
posterior corner of the patch of hairs. Abdomen with the fifth 
segment slightly elongated; upper surface bare, no hairs at the 
sides of the second segment. Hypopygium minutely bristly 
at the sides and below. Legs slender, the front tarsi somewhat 
stouter than usual, but not greatly thickened, the metatarsus 
much narrower than the tibia. Middle and hind tibise with 
distinct hair-seam along the upper edge, and with a single row
