9. Metanotum distinctly grooved at 1:)ase ; upper margin of clypeus nearly 



evenly convex Arachnophroctonns. 



Metanotum not grooved at base ; upper margin of clypeus sinuate or 

 zigzag Batazonus. 



The groui)s or subgenera of Psauiinocharcs distinguishable in the female 

 only are as follows : 



I. Clypeus plainly emarginate in middle LophopompUus {(cthiops, atrox). 



Clypeus not more than evenly concave 2 



2. No distinct tarsal comb ■inoplius {iUinoisensis, virginiensis). 



A distinct tarsal comb 3 



3. Third joint of antennae very short; hardly longer than first. 



Sophropompilus (ingeiiuus). 

 Third joint of antenna; much longer than first Psaiiimochares. 



The discovery of additional characters will douljtless raise these to generic 

 ranks. 



Pompilogastra equals Loplwpompilns. and Pycnopompiliis equals Psammo- 

 chares. 



Psammochares ithaca, new species. 



Female. — Clypeus slightly hairy, rather rounded in front, antennae slender, 

 but not very long, the basal joint not hairy, the third much longer than first, 

 but second plus third hardly as long as width of vertex, the short furrow above 

 antennse does not reach ocelli, anterior ocellus not more than diameter from 

 laterals, and these about as near to each other as to eyes ; vertex straight across, 

 with long erect hair, as also on the face; pronotum angulate behind, metanotum 

 short, rounded, with a broad deep median furrow, slightly hairy above, more 

 dense on sides ; abdomen not flattened, bristly at tip. and ventral segments with 

 a few hairs on each ; legs long, the tarsi long and slender, no distinct comb on 

 anterior tarsus, the spines short and straight, the long spur on hind tibia 

 hardly more than one-half the metatarsus; spines beneath last joint of hind 

 tarsi, claws long, with tooth, almost cleft. Wings black, paler on basal part, 

 but not as much difference as in P. virginiensis, second submarginal quadrate, 

 receiving the first recurrent vein near tip, third submarginal as large, but 

 narrowed above, receiving the second recurrent a trifle beyond the middle, this 

 vein arising from beyond middle of anal cell, basal veins interstitial, in hind 

 wings the cubitus is interstitial with end of the cell. Color wholly black ; 

 belongs to section of Anoplius. 



Expanse 16 mm. 



From Ithaca, N. Y., early July; related to P. virginiensis but dis- 

 tinct by grooved metanotum. 



Psammochares bellicosus, new species. 



Male. — Black, iridescent blue and purple, a patch of silvery each side 

 between antennae and eyes. Clypeus truncate below, only a little hairy ;
