 vae and pupae. Spring Grove: May 14,

Molanna Curtis 



Molanna Curtis (1834, p. 214). Genotype, 

 monobasic: Molanna angustata Curtis. 



Apatania Kolenati (1848, p. 75). Genotype, 

 monobasic: Phryganea vestita Zetterstedt.

Neophylax fuscus Banks 



Neophylax fuscus Banks (1903^, p. 242); cf , 

 9. 



Not yet taken in Illinois, but found in the 

 Meramec River near Steelville, Missouri, 

 which is west of St. Louis and not far from 

 Illinois. In addition to Missouri, the spe- 

 cies is known from Michigan, New Hamp- 

 shire and Virginia. The species recorded 

 as fuscus by Betten (1934) is not fuscus 

 but a species identical with or closely re- 

 lated to stolus. 



Neophylax ayanus Ross 



Neophylax ayanus Ross (1938fl, p. 168); cf, 

 9. 



Not yet taken in Illinois. The only rec- 

 ords for this species are from Louisville, 

 Kentucky, and Cataract, Indiana; the latter 

 is only about 40 miles from the Illinois 

 line, near Terre Haute. 



MOLANNIDAE 



This family is represented in the Illinois 

 fauna by only one genus, Molanna. The 

 genus Beraea has frequently been placed in 

 the family Molannidae but is treated as a 

 separate family in this paper. 



medium length situated above base of man- 

 dibles, and the curious, reduced hind tibia 

 and claw. The curious, flanged case, fig. 

 710, is also characteristic of the genus, al- 

 though a similar case is made by some spe- 

 cies of Athripsodes (see p. 228). The adults 

 have the maxillary palpi five segmented in 

 both sexes. When at rest the adults sit with 

 the wings curled around the body and with 

 the body held at an angle to the surface 

 upon which the insect rests, its mottled gray 

 color giving the insect in this position a 

 remarkable resemblance to a rusty nail head 

 or a very small twig. 



Five North American species are known, 

 of which three have been taken in Illinois, 

 and it is quite possible that stray specimens 

 of the other two may eventually turn up 

 from this state. 



No characters have yet been discovered to 

 give certain identification of the females and 

 larvae. For this reason it is necessary to 

 disregard for the present the species cinerea, 

 represented by the female type of which only 

 fragments remain.
