numerous and well developed on main veins and some cross veins. 
The venational details of the holotype are shown in figure 2. 
Holotype: No. 5874a!), Museum of Comparative Zoology; col- 
lected by F. M. Carpenter, in the lower layer of the Elmo limestone 
in 1927. The specimen consists of a very nearly complete fore wing, 
lacking only the distal wing margin. A second specimen (No. MCZ 
5875ab), with the same collecting data, consists of the proximal two- 
thirds of a fore wing; a drawing is included here to show the ap- 
parent fluctuation in the venation. Also on this piece of rock, only 
2 or 3 mm. from the wing, is part of a femur and tibia of a leg; 
the proximity and size of this leg indicate that it is from the same 
insect as the wing. The tibia is armed with two rows of heavy spines 
and the femur bears a few smaller ones.

Fore wing: length, as preserved, 20 mm.; width, 7 mm.; estimated 
complete wing length, 30 mm. Costal area with a more prominent 
broadening than in grandis ; area between CuA and CuP with fewer 
cells; wing at least four transverse bands. Venational details are 
shown in figure 5. 
Holotype: No. 15584, Peabody Museum, Yale University; col- 
lected in Elmo limestone by C. O. Dunbar, 1921. 
This species differs from grandis mainly by the wing markings 
and smaller size. 
Genus Paracladus, new genus 
Fore wing: costal margin almost smoothly curved; Sc with sev- 
eral oblique 'veinlets, mostly branched, but generally much less de- 
veloped than in Homocladus; Sc apparently terminating either on
