tables, but Lundbeck has grouped them together with a few othe^* 
European species on the basis of the two scutellar bristles, very 
short costa and the enlarged bristle with a patch of small ones 
on the mesopleura above. 
Aphiochaeta simplicior sp. nov. 
d^. Length 1.9 mm. Black, the lateral margins of the 
mesonotum fuscous; pleurae fuscous above, yellowish brown 
below; front legs light brownish yellow; middle and hind ones 
much darker, fuscous, with the posterior surface of the tibiae 
almost black; palpi and terminal lamella of hypopygium honey 
yellow or brownish. Wings strongly tinged with brown, venation 
piceous. Halteres black. Front about one-fourth wider than 
long; four post antennal bristles, all large, but the upper con- 
siderably stronger and placed unusually far above the lower 
ones; upper pair separated by a little more than one-third of 
the width of the front, the lower pair half as far apart; bristles 
of lowest reclinate row rather close together at the side of the 
front, their bases indicating a line 45° from the vertical; lateral 
one on a level with the upper postantennal and very close to the 
eye; next row above of four equidistant bristles forming a line 
that curves slightly downward at the middle; ocellar row large 
and strong like the others; ocellar tubercle and median frontal 
groove well developed, the surface of the front slightly pollinose. 
Antemiie rather large, oval; arista slightly longer than the head 
height, very thinly pubescent. Palpi with long stout bristles 
apically. Cheeks each with three strong downwardly directed 
bristles and a row of short ones between these and the antenna. 
Mesonotum rather shining, almost bare in front; highly convex; 
one pair of dorsocentral bristles, with irregular bristly hairs be- 
tween them. Scutellum rather long, scarcely twice as broad as 
long, with two large marginal bristles and two microscopic hairs. 
Propleura with four bristly hairs above and four longer ones 
below, but with none between these. Mesopleura above with a 
patch of bristly hairs, but without any greatly enlarged bristles 
although those near the posterior margin are distinctly larger. 
Abdomen with the second and sixth segments slightly length-
