brown; two basal, mid-tarsal joints and the hind basal tarsal 
joints light brown. Hind tibiae with a short, inconspicuous, ven- 
tral apical spur; hind femora considerably thickened in the mid- 
dle, more slender on the posterior half than on the basal half and 
all of the thickening confined to the dorsal side of the femora. 
Hind trochanters with a long spur. Metasternum pubescent; 
without spur. Wings: strongly tinged with brown on the anterior- 
apical half, becoming diffuse posteriorly; the color more sharply

Temnostoma japonicum n. sp. 
Related to bombylans Fabr., but differing in the dark pattern 
of the wing, the basally black femora, etc. 
Male. Length 14 mm.; wing 11 mm. Head: eyes bare, almost 
touching in the middle. The vertical triangle is obcurely shining 
black, but only as far as the corner of the eye; the entire occiput 
is dull, brownish-golden pollinose, narrowly divided in the mid- 
line and extending just a little further posteriorward along the 
eye margin. The lower part of the front golden pubescent except 
for a prominent, acute, shining black triangle above the antennae, 
its apex continued as a narrow line to the narrow black area be- 
tween the eyes. There is a smaller, impressed black triangle 
within the larger one. Face shallowly concave below the anten- 
nae, broadly shining black, finely striate in the midline, the mid- 
facial stripe expanding to a large triangular area below the an- 
tennae; elsewhere the face is broadly golden-yellow pubescent, 
and with only very short, sparse, pale pile upon the lower part of 
the face in front of the cheeks. Antennae light orange, the third 
joint oval after an oblique fashion, its margin rounded. Arista 
light orange, the cheeks shining black. Front without pile, that 
of the vertex shining yellowish. Thorax: dull black, scutellum of 
the same color, the mesonotum with a pair of obscure greyish 
vittae set close together that run half of the distance from the 
suture to the scutellum. There is a conspicuous, laterally widened,
