times as hr(ja<l as long, tiiherculate above, rather dull yellowish red, with a nar- 

 row, black, impressed niediat) stripe, rest of thorax similar in color, the black 

 strijie extending across mesothorax, but broader; abdomen brownish yellow, 

 paler beneath ; legs pale yellowish, with black spines. Forewings clothed with 

 short yellow hair, indistinctly irrorate with pale brown, more distinct on anal 

 region, costal and subcostal areas unmarked, venation red-brown, very distinct; 

 hind wings hyaline, faintly grayish at tips. The forewings are rather narrow, 

 the outer edge oblique, tlie discal cell much longer than its pedicel, fork 1 barely 

 extending upon discal cell, fork 3 acute at the anastomosis in both wings; outer 

 margin of bind wing strongly indented just behind end of fork 5. Expanse 27 

 mm. 



Specimens frotii Ithaca, New York ; Mu.'^koka, Ontario, Canada ; 

 and Lake Forre.st, Illinois. 



I liad considered this to be C. coasocia Walk , but recently have 

 received an allied species, with basal joints of antennje black ; thus 

 agreeing better with C- consosla. Both have the dorsal black stripe. 

 C. consocia is smaller, and the fork 3 of all wings is pedicellate, not 

 reaching the anastomosis; the markings are heavier in the middle 

 of the wings, and paler in anal region. I have it from New Hanip- 

 shire. 



PY€l«OI»SYCHE new gen. 



A Limnephilid ; spurs 1-8-4; ocelli rather small; pronotum of 

 two rather prominent bristly lobes, more prominent than iu Steno- 

 pht/lax ; thorax with a bristly wart at base of each wing, and a pair 

 of smaller, elongate ones near middle of mesothorax ; wings very 

 broad at the pterostigma, costal margin much rounded, apical mar- 

 gin oblique; membrane granulate; discal cell longer than pedicel, 

 apical lialf on upper side concave, fork 3 goes back no further than 

 fork 1 ; in hindwings fourth apical cell has an oblique base, but 

 just before base is narrower than second apical cell. 



Type. — Limnephila scabripennis Rambur. 



Hagen put it in Halesus, Walker described it as a Neuronia ; I 

 have kept it in Stenophylax, but it is better in a new genus.
