436 Timehri. 
Pro-mesonotum and scutellums closely, distinctly punctured, the post- 
scutellum densely covered with long grey hair. Metanotum smooth in the 
middle of the base, the rest alutaceous, the sculpture stronger on the sides. 
Tachytes ametina, sp. n. 
Black, the apex of the fore femora narrowly, of the middle more broadly, 
more than the apical half of the posterior and all the tibie and tarsi rufo- 
testaceous, the wings hyaline, the costa and stigma and basal nervures rufo- 
testaceous ; the basal abscissa of radius roundly curved, as long as the 3rd ; the 
2nd about one-quarter shorter ; the lst recurrent nervure is received near the 
base of the cellule, the 2nd before the middle ; heact and thorax densely covered 
with pale fulvous hair, the apices of the abdominal segments covered with pale 
golden, almost silvery pubescence ; the pile on the pygidium, almost silvery. 
Hyes distinctly converging above, separated there by a little more than the 
length of the 3rd antennal joint. Tibial and tarsal spines pale, the apical joint 
of the hind tarsi black. Female. 
Length 14 m.m. 
Labrum and middle of mandibles in front red ; the base of mandibles densely 
covered with pale golden pile. There is a longish triangular fovea on the top 
of the apical slope of the metanotum. Pygidium a little longer than it is wide 
at the base ; the apex is not narrowed toa fine point ang is transverse. Tegule 
testaceous. 
Tachytes pretiosa, sp. n. 
Black, head and thorax densely covered with pale fulvous pubescence, the 
apices of the abdominal segments with a band of pale fulvous pile ; the pygidimn 
covered with bright golden pile, its apex narrowed to a point ; tibie and tarsi 
covered densely with silvery pile, their spines white, the spurs and claws 
rufous ; the long spur of the hind tibie is clearly longer than the metatarsus, 
which is curved and narrowed at the base. Wings fulvo-hyaline, clearer at 
the apex, the costa, stigma and nervures fulvous, the latter darker at the 
apex ; the lst abscissa of the radius is curved and is as long as the 3rd ; the 
2nd is shorter ; the 1st recurrent nervure is received the length of the 2nd 
abscissa of the radius from the base of the cellule, the 2nd in the middle. 
There is a shallow, wide furrow, widened at the apex, down the centre of the 
basal part ; there is a more clearly defined furrow down the middle of the 
apical slope, its centre deep, the sides obliquely sloped ; it is narrowed at the 
top and: bottom. Female. 
Length 13 m.m. 
yes at the top separated by the length of the 3rd antennal joint. Clypeus 
closely, distinctly punctured. Palpi.testaceous. ‘The 3rd antennal joint is 
not much longer than the 4th. Base of mandibles covered with silvery 
pubescence. 
Crabro stirocephalus, sp.n. 
Black, the antennal scape, a line on more than the outer third of the pro- 
notum—almost twice the length of the black central part, a broad oval spot
