dorsum, but several systems of delicate hairs, some representing the acro- 
stichals ; but the dorsum is too much damaged by the pin to give a definite 
account. Chaetotaxy, as far as possible, shown in fig. 35. A unique feature 
is that on the edge of the notopleurae, just posterior to the humeri, are very 
minute black teeth-like spines. There is a single pair of erect apical bristles 
on the scutellum. 
Wings with the anal angle more pronounced than'in L. nigra; vem 
lst A, though weak, is continued well to the margin; venation otherwise

Genus BRAcHvsTOMA Meigen. 
In his characters of this genus Melander* states that the anal angle of 
the wing is gone, while Shiner} asserts that this angle projects (Fligellapper 
vortretend). It is upon the latter author’s classification that I pla 
following species in Brachystoma, although the eyes of both species are 
not holoptic, but widely separated beneath and holoptic above the antennae 
in both sexes. The two following species agree so closely that it is with 
some hesitation I separate them; the genitalia of the males, however, differ 
to some extent.
