Protohymen permianus Tillyard, Amer. Journ. Sci. (5) 
11 (61) : 58, 1926. 
Fore wing: length, 10-13 mm.; width, 3 mm.; at the 
base the costa bends outward slightly, but there is no pre- 
costal area; R comes in contact with the costa before the 
divergence of Cul and Cu2, and at the middle of the ptero- 
stigma it diverges downward toward the apex ; Cu2 
strongly undulated. Cross-veins: one between R1 and 
R2 + 3; one between R2'3 and R4 + 5; two between R4 + 5 and 
MA; two or three between MA and MP; one between 
MP and Cul; two or three between Cul and Cu2; two 
between Cu2 and 1A ; one or two between 1A and the hind 
margin; the cross-veins between 1A and the hind margin 
are always attached to the distal half of the anal vein. 
Hind wing: length, 9-11 mm.; width, 3.5 mm.; vena- 
tion nearly identical with that of the fore wing ; the length 
of the oblique vein between MP and Rs + MA is less than 
in the fore wing. 
Holotype: No. 5001 (hind wing), Peabody Museum, 
Yale University; paratype: No. 5002 (fore wing), Pea- 
body Museum; No. 1702, Tillyard collection. 
In the Harvard collection there are ten specimens of 
this species, as follows: No. 3060ab, fore and hind wings 
complete, with fragments of head and thorax; No. 3061ab, 
fore and hind wings, folded together, but well preserved; 
No. 3062ab, hind wing, complete; No. 3063ab, fore wing, 
nearly complete; No. 3064ab, one pair of fore and hind 
wings (J. W. Wilson, collector) ; No. 3065ab, hind wing, 
complete except for the base; No. 3066ab, basal third of 
wing; No. 3067, middle third of wing; No. 3068ab, distal 
third of wing; No. 3070ab, basal two-thirds of wing. All 
specimens collected by F. M. Carpenter, unless otherwise 
indicated. In the Sellards collection there are two speci- 
mens: No. 1068, distal two-thirds of fore wing; No. 1558, 
distal third of wing. 
The holotype specimen of this species is well preserved, 
but the base of the wing is missing. Since none of the 
other Yale specimens have this part preserved, Tillyard’s 
figure is incomplete at the base. The wing is longer and 
more nearly petiolate than he supposed. The subcosta is
