Laphria mauroides sp. nov., d, 9 
Belongs to the group of species with black 
legs and wings darkened along the veins, 
closely related to L. dayi sp. nov., but dis- 
tinguishable by the presence, immediately 
over the scutellum, of short rather strong 
bristles, even on the declining part of meso- 
notum, by an irregular disposition of hairs 
on mesonotum (in L. dayi they are less nu- 
merous and distributed in longitudinal rows), 
and moustache tubercle not very sharply sep- 
arated from the upper part of face. 
Body black, shining. Head with greyish 
dust, very similar to that of L. dayi or L. 
mode st a. 
Mesonotum with similar markings as in 
L. dayi , but with short black hairs irregularly 
distributed. Wings dark, rather broad, the 
veins closing the discal and 4th posterior cells 
very close together and nearly parallel (Fig. 
5 a). Pleurae nearly entirely grey dusted, only 
the disc of the mesopleurae black, shining. 
Legs black, with hairs predominantly white. 
Femora moderately swollen. Halteres yellow. 
Abdomen as in L. dayi sp. nov. 
Length of body 15 mm., of wing 12.5 mm.

Laphria lukinsi sp. nov., d, 9 
Belongs to the group of species with black 
legs. Distinguishable at once by the yellow 
apical part of the abdomen. 
Head black, with yellowish dust, hairs and 
bristles. The hairs at sides of face are flat and 
scalelike. Proboscis long, slightly shorter than 
head height, strongly compressed laterally. 
Palpi very small, hairs light coloured. 
Mesonotum black, dull, with some yellow 
markings beside humeral calli. Short hairs 
black, but the longer ones in the prescutellar 
area yellowish. Bristles black, but those on 
postalar calli and scutellum yellow, very thin. 
Disc of scutellum with yellow depressed 
hairs. Underside of thorax yellowish dusted, 
with yellowish hairs and bristles. Only one 
black bristle on mesopleurae. Halteres yellow.
