apices of the femora, and the tibiae (except a dark stain on their 
inner side) testaceous. Head punctured. Width of vertex between 
the eyes equal to the combined length of the first four joints of the 
flagellum ; orbits parallel sided ; the face on each side more or less 
clothed w’ith silvery hairs ; clypeus finely punctured, its centre 
produced into a short angular process wdiich is carinated on the 
centre, and slightly raised on its margins. Antennae with the third

slightly longer than the fourth. Mesonotum (including the scutel- 
lum) shiny, clearly and rather remotely punctured, clothed with 
inconspicuous greyish hairs. Wings hyaline, their nervures pale 
testaceous, radial cell truncate at the apex, third submarginal 
shortly ligulate. Mesopleurae transversely rugose, and sparingly 
clothed with silvery hairs ; propodeum without a definite dorsal area, 
transversely rugose, its posterior declivity with a well-marked central 
fovea, the sides diagonally strigose and clothed with silvery hairs. 
Legs w’ithi the tibiae spinose, front metatarsi with a comb of six 
moderately long pale spines; abdomen shining, with scarcely per¬ 
ceptible sculpture, the apices of the segments narrowly discoloured 
(the discoloration widening along the sides of the segments) ; basal 
segment about as long as wide ; dorsal area of apical segment very 
largely punctured, its margins raised and testaceous. Beneath 
shining. 
Long, [about 7 mm.]. 
This insect was submitted by Mr. Morice to Herr F. F. 
Kohl some years ago, and bears a label in the latter’s hand¬ 
writing. “ Tachysphex n. sp. transiens ad rarapiagetia, 
Kohl.” Had it not been for this I should scarcely have 
dared to place it in this genus.
