Subgenus Sphex Linnseus 
Sphex (Sphex) coronatus (Costa). 
Ammophila coronata Costa, Ann. Mus. Zool. Napoli 2 (1862-1864) 111. 
Ammophila superciliaris Saussxjre, Reise d. Novara, Zool. 2 1 Hymen- 
optera (1867) 24. 
There seems no reason to doubt the above synonymy as both 
descriptions certainly apply to the species treated below. This 
species, although resembling atripes in general appearance, may 
readily be distinguished by the characters mentioned in the pre- 
ceding key. The male is without red markings and shows 
very little variation, but the females vary some in the color of 
the legs and abdomen. Four females represent a variety in 
which the first two tergites are largely reddish and the tarsi 
almost entirely reddish. These color differences are not accom- 
panied by any differences in structure. The structure varies 
somewhat, as certain specimens have a few rugae on the side of 
the pronotum and there is some variation in the rugosity of the 
mesoscutum. 
Typical females from: LUZON, Laguna Province, Los Banos 
( Baker 372, 6844) : Bataan Province, Lamao {C. V. Piper), 
{ C . R. Jones), accession No. 844, Bureau of Agriculture. 
Females of the color variety from: Mindanao, Davao ( Baker 
6845) ; Dapitan ( Baker 3207) ; Iligan ( Baker 3205). Panay, 
Antique Province, Culasi, June, 1918 (R. C. McGregor) . Males 
from: Luzon, Laguna Province, Los Banos ( Baker 374) ; Mount 
Maquiling {Baker) ; Bataan Province, Lamao {C. R. Jones), 
accession No. 840, Bureau of Agriculture. Mindanao, Iligan 
{Baker 3206) ; Cagayan {Baker 3820). 
Sphex (Sphex) atripes (Smith). 
Ammophila atripes Smith, Bingham, Fauna Brit. India, Hym. 1 (1897) 
229; Ashmead, Proc. U. S. Nat. Mus. 28 (1904) 150. 
Ashmead and Brown seem to be the only ones to record this 
species from the Islands, and I doubt if their records were based 
on specimens. I have seen no specimens of atripes from the 
Philippines but have included the species in the above key so it 
can be identified if it occurs there and to point out certain 
differences between it and coronata. 
Subgenus Ceratosphex novum 
This subgenus can be readily distinguished from true Sphex 
by the presence of two teeth on the tarsal claws at the base 
beneath. It bears about the same relation to Sphex as Para -
