NEUEOPTEEA TEICHOPTEBA LIMNOPHILLD^S. 193 



LIMNOPIIILUS Burmeister. 



This genus has never been reported fossil, and in placing in it the 

 species below the intention is only to indicate its affinities. The genus is 

 boreal and wide spread, and the larvae are generally found in standing 

 water 



LlMNOPHILUS SOPORATUS. 

 PI. 15, Fig. r>. 



A couple of specimens are referred here, in only one of which is the 

 neuration sufficiently distinct to be determined with any probability, and in 

 this it is somewhat obscure and is not fully shown in the plate ; nearly all 

 the veins and cross-veins in the outer half of the wing can, however, be 

 traced with more or less distinctness, though the cross-veins are certainly 

 obscure; the neuration, as thus limited, is wholly that of Limnophilus. 

 Tin- fnmt win^s are moderately long and narrow, the costal margin rather 

 strongly arched in the apical half, curving downward to the bluntly acumi- 

 nate apex, the apical margin sharply and very obliquely truncate Dis- 

 coidal cellules short, much shorter than its foot-stalk; anastomosis of the 

 lower half of the wing continuous.

I n certain parts of Auvergne, France, rocks are found which for a thick- 

 ness "I sometimes two meters or more are wholly made up of the remains of 

 tin- cases of caddis-Hies. These have lieen frequently mentioned by writers 



and were tirst described and figured li\ liosc early in the century under the 

 name of Indusia mlmlosa. <>u-talet in his recent treatise on the fossil in-
