188 EMBRIK Srrano, 
1—5 and ventral segments 2—4, a spot on the anterior coxae and 
a line on all the femora beneath yellow. Wings hyaline, nervures 
black, stigma fusco-ferruginous. | 
Length 10 mm. 
Hab. Longavi, Parral, Chile (ScHönemAnn). 4 specimens. 
I place this species in Telephoromyia with some hesitation, as 
in some points it shows affinity with Ornepetes. But the tridentate 
mandibles, the proportion of the joints of the maxillary palpi and 
the longer hypopygium seem to remove it from that genus. Except 
in the mandibles it approaches AsumeAp’s genus Spilothynmus, which 
I consider very doubtfully distinet from Telephoromyia.

2. Mandibles bidentate, the outer tooth acute, the inner short 
and truncate, with a broad eutting edge. Clypeus not produced, 
sparsely punctured, with a minute tubercle in the middle, a long 
narrow depression simulating an emargination from the base of the 
tubercle to the apical margin, the anterior angles of the depression 
produced into a short spine on each side. Antennae a little longer 
than the thorax and median segment combined, the apical joints 
arcuate, the interantennal prominence scarcely bilobed, divided by 
a very shallowly impressed longitudinal line. Head closely punctured, 
more coarsely on the front than on the vertex; thorax closely punc- 
tured; the 'seutellum shining, strongly convex and more sparsely 
punctured, with a transverse row of deep punctures at the base. 
Median segment rounded, finely and shallowly punctured. Abdomen 
elongate, sparsely punctured, tapering at the extremities, the apical 
half sparsely covered on the sides and beneath with long cinereous 
pubescence. Seventh dorsal segment narrowly truncate at the apex; 
the hypopygium produced a little beyond it, small and rounded. 
The posterior femora are concave beneath at the apex and produced 
into two short apical processes. The second cubital cell is not more 
than two-thirds of the length of the third on the radial nervure 
and receives the first recurrent nervure beyond the middle, the 
second recurrent nervure is received at one-third from the base of 
the third cubital cell. 
Black; a broad band on the clypeus reaching the anterior 
margin on the sides but following the depression in the middle,
