52(j ]\Ir. E. Saui^rs on Hymeno'ptera Aculeata: 
vertex between the eyes scarcely so wide as the second and third 
flagellar joints taken together ; pro- meso- and metanota very shining 
and polished, with only a few very scattered punctures; ineso- 
pleurae dull, exceedingly closely and finely punctured ; wings nearly 
hyaline; propodeum above dull, finely and longitudinally rugulose, 
clothed with very short and inconspicuous greyish hairs, its sides 
diagonally striate ; anterior tarsi with a comb of slender and not 
very long brownish hairs. Abdomen shining, but not polished like 
the thorax ; finely punctured on the basal segments, those towards 
the apex being almost impunctate ; apical dorsal valve polished and 
elongate, its shape much as that of pectinipes. 
Long. 7 mm. 
The polished, almost impunctate, mesonotum, etc., of 
this species will distinguish it at a glance.

11. Tachysphex capitalis, n. sp. 
Species insignis ; nigei’, mandibulis,tegulis, abdomine pedibusque 
testaceis. Caput maximum, vertice latissimo, articulis 1, 2, 3, 4 
antennarum flagelli simul sumptis aequali ; pronotum oblique- 
strigosum ; propodeum transverse-striatum; abdomen impunctatum, 
valvula dorsali lata punctis remotis impressa. 
9 Head and thorax black, clothed with silvery white hairs. 
Mandibles, tegulae, wing-veins, legs, and abdomen testaceous, wings 
with a yellowish tinge. Head unusually produced posteriorly (from 
a sideways view the cheeks behind the eyes are as wide as the eyes 
themselves) ; vertex between the eyes exceedingly wide and convex 
(as wide or even wider than the fir-st four joints of the flagellum). 
This great width gives the face a most unusual appearance for that 
of a species of this genus. Clypeus flat, its apex slightly elevated, 
shining and bituberculate. Antennae with the second joint of the 
flagellum nearly once and a half as long as the third. Pronotum 
diagonally strigose ; mesonotum and mesopleurae thickly clothed 
with silvery hairs ; propodeum clothed with long silvery hair.^, 
transversely rugose above, diagonally so at the sides. Legs rather 
thick ; front metatarsi with seven rather stout jjale spines. Abdomen 
almost smooth, and without evident puncturation. The sides of 
the second and following segments are clothed with silvery pubes¬ 
cence, visible only in certain lights, meeting almost in the centre 
of the segment; apical dorsal valve widely triangular, and with 
large scattered punctures. 
Long. 13 mm.
