margin or Ri; origin of Rs at or slightly beyond mid-wing, its 
branches arising dichotomously ; CuP only very slightly curved dis- 
tally, without the terminal extension as in Plomocladus. Microtrichia 
on wing membrane more numerous than in Plomocladus ; setae on 
veins apparently less developed and less numerous. 
Type-species: Paracladus retar datus , n. sp. 
This genus, though clearly related to * Honiocladus , differs by the 
late origin of Rs, and especially by the absence of the marginal ex- 
tension of CuP; in the latter respect, it resembles Strephocladus. 
Paracladus retardatus, n. sp.

Length of fore wing, as preserved, 20 mm.; width, 7 mm.; esti- 
mated complete wing length, 30 mm. Subcosta space distinct and 
rather wide, with a few cross veins; relatively few cells between 
CuA and CuP; iA connected to CuP distally by a strong, longitu- 
dinal cross vein. Wing markings absent. Venational details are 
shown in figure 6. 
Holotype: No. 5877ab, Museum of Comparative Zoology; col-

Fore wing: membrane apparently thin, at most weakly coriaceous; 
wing generally oval but often very short; Sc extending at least to 
mid-wing, often considerably beyond; area between Sc and Ri at least
