4. Length 15 mm.; second and third cubital cells on the radius about the same 
length; robust, black species; anterior wing 10 mm. long. 
Salius florissantensis (Ckll.) 
Length less then 12 mm.; third cubital cell distinctly longer than the second 5. 
5. Slender black species; length 10 mm.; length of anterior wing 6 mm.; head sub- 
quadrate; basal n. 120 # basad of tr. med. . ; Salus scuddert (CkIL.) 
Robust species with abdomen a little paler than thorax; length 11 mm.; length of 
anterior wing 9 mm.; head subtransverse; basal n. 680 » basad of tran. med. 
Agenia saxigena Ckll. 
AGENIA SAXIGENA CKIl. 
Besides the reverse of Prof. Cockerell’s type, I have seen a specimen of this 
species from Fossil Stump Hill, 1907 (W. P. Cockerell). 
AGENIA COCKERELL Nn. Sp- 
©. Length about 13 mm.; length of the anterior wing 7.5 mm. Head about 
the same width as the thorax, normal for this broad type. Head and thorax sub- 
tily sculptured, at the sides of the thorax it is slightly aciculate. Legs moderately 
robust; fore femora not swollen, normal; middle tibiae without spines, and with 
the longer spur almost as long as the basitarsus; hind and fore tibie indistinct. 
Radial cell broadest where the second tr. cu. joins the radius; stigma very small, 
only the apex remaining; first tr. cu. strongly curved toward the base of the wing, 
making the second cubital cell much broader on the cubitus; second tr. cu. almost 
straight; third tr. cu. on the lower part strongly curving toward the apex of the wing, 
making the third cubital cell much broader on the cubitus; second cubital cell much 
larger than the third, receiving the first recur. n. distinctly beyond the middle; third 
cubital cell receiving the second recur. n. somewhat beyond the middle; first discoidal 
cell long and acute at the apex, distinctly but not markedly longer than the first 
cubital: tran. med. not basad of the basal nervure, but its exact position is hidden 
by a leg. Abdomen sessile, broad, impunctate. Head and thorax black; abdomen 
and legs rufous. Basal half of wings hyaline, apical half dark fuscous; venation 
dark brown. ‘The following measurements are in 2: —
