AMERICAN TRICHOPTERA— NOTES AND 

 DESCRIPTIONS. 



BY NATHAN BANKS, EAST FALLS CHURCH, VA. 



In the following pages are descriptions of various new caddice- 

 flies, mostly from my own collection. I have given a new arrange- 

 ment of the genera of the Hydropsychidae based on a salient, but 

 hitherto unused character, which makes the classification of this 

 family easier than before. 



PHRYGANEID^. 



Neuronia smithi, n. sp. (PI. VIII, fig. 11). 



In general similar to N. concatenata, but the irrorations on 

 the wing a little further apart, and much less wavy; the vertex 

 wholly pale yellowish, the thoracic notum also pale, but rather 

 dark each side. Venation generally as in N. concatenata, but the 

 first fork does not reach half way back on discal cell (in concatenata 

 much more than half way). The lower appendages of the male 

 have the apical spine longer and less curved than in N. concatenata. 



Expanse 23 mm. 



From Lakehurst, N. J., 4th July (Englehart). Named in 

 memory of the late Dr. J. B. Smith. 



limnephilid.f:. 



Limnephilus spinatus, n. sp. (PI. VIII, figs. 8, 9). 



Palpi yellow; face dark, with yellow hairs, vertex and thorax 

 dark, with some yellow hair and black bristles; antennae brownish, 

 the basal joints darker; abdomen black above and on the sides, 

 vertex pale; legs yellow, with black spines, those on tibia 1 are 

 very short; wings, except costal and subcostal areas, are brown, 

 marked with pale spots, these most numerous in front and along 

 the veins, basal part of apical cells pale, beyond the brown is densely 

 spotted with minute pale dots, the usual median oblique mark is 

 distinct; hind wings hyaline, venation yellowish. In the fore wings
