322 JIandlirsch — New Paleozoic Insects from the 



with a short apical fork. Cubitus very well developed, cleft 

 near the base, the anterior main branch splitting by repeated 

 forking into a greater number of twigs, one of which reaches 

 the media, the others going parallel with the branches of the

sector and with the media to the margin; the posterior main 

 branch splits into a bundle of divergent twigs, falling obliquely 

 to the posterior margin. Anal area broadly lancet-shaped, 

 separated from the wing by an S-shaped waved vein. All the 

 interstices between the main veins are bridged over by verti- 

 cally arranged simple cross veins. 



It is a curious fact that original color patterns, consisting of 

 a number of broad and very regular transverse bands, have 

 resisted destruction through petrifaction. Similar patterns 

 have been found in some fossils of Commentry, as in Cnemi- 

 dolestes and Protophasma. Unfortunately the venation of 

 the Cnemidolestidse not being sufficiently known, it is at pres- 

 ent impossible to suppose that any relation exists between the 

 two groups because of their similar color patterns.

Front wing elliptical, scarcely two and a half times as long 

 as broad, about 43 mm in length, 37 mm of which is preserved. 

 Costal area very broad, subcosta extending but little beyond 

 the middle of the wing, uniting with the radius. Radius 

 not far removed from the subcosta, not reaching quite to 

 the tip of the wing and sending forth, like the subcosta, a num- 

 ber of very regular oblique and straight veinlets, directed for- 

 ward and bridged over by delicate cross veins.
