Sophropompilus mohave sp. nov. 
$ Differs from bradleyi and tumiformis in less hairy head 
and body. From subangulatus in shape of pronotum and 
in shorter propodeum, from parvus in having ocelli about 
as near eyes as to each other. 
Deep bluish black, antennae and tarsi dull black, fore- 
wings violaceous black, hind wings hyaline, tips clouded; 
clypeus and lower part of face silvery. Clypeus broad, 
truncate in front ; face with very short hairs ; vertex nearly 
straight across, with some long hairs; ocelli subequal, in 
low triangle, posteriors about as near to eyes as to each 
other; occiput strongly silvery; antennae short as usual, 
third joint not longer than fourth; pronotum arcuate be- 
hind, with few extremely short hairs above; propodeum 
fully as short as in parvus , with few, short erect hairs 
above ; pleura without hair ; abdomen with only a very few 
short hairs near tip above, below more hairy, but also short. 
Legs smooth on femora and tibiae, front coxae with a few 
long hairs in front, mid and hind tibiae with short scattered 
spines ; inner spur of hind tibia a little more than one-half 
of basitarsus ; front tarsus with three long comb spines on 
basitarsus. Venation very similar to eastern S. hyacinth i~ 
nus , but the marginal cell longer, in this respect like the j 
western S. tumifrons. 
Length 9 mm., fore wing 6.5 mm. 
From Tempe, Arizona, 1 August, and southern Arizona !

Psammochares fabricii, nom. nov. 
Dr. J. Bequaert has shown that the Sphex tropica of Fab- 
ricius (which is a Psammocharid) is not the same as the 
older Sphex tropica of Linnaeus (which is a Vespa) . It is | 
therefore necessary to rename the species which Cresson 
(Trans. Amer. Ent. Soc. I, 98, 1887) treated as Pompilus 
tropicus ; I presume, but do not know, that the species called 
Sphex tropica by Fabricius is the same.
