350 NEUROPTERA. 



Bittaciis arizonicus n. sp. 



Closely related to B. occidentis, of same color, thickened 

 femora, etc. But the male genitalia are more scabrous at 

 tip, the superior pieces are more pointed, and narrower at 

 tip and the inferior median piece has an apical tooth that can 

 be seen in side view. The size is the same. 



From Palmerlee, Arizona, August. 



TRICHOPTERA. 



LIMNEPHILID^. 

 StenopUylax calypso n. sp. 



Head yellow ; basal joint of the antennae yellowish, beyond brown- 

 ish, rather strongly serrate beneath ; ocelli large; anterior warts small, 

 posterior warts narrow, transverse, nearly twice their length apart, 

 these, the pronotum, and parts of mesonotum with black bristles. 

 Thorax yellowish, darker above base of the fore wings ; abdomen yel- 

 lowish brown, darker at tip; legs pale yellowish, the tarsi and tibiae 

 rather reddish yellow, all with black spines ; preapical spurs short, 

 nearly twice their length before the apex ; last joint of hind tarsi with- 

 out spines beneath. Wings pale brownish, with many (perhaps 100) 

 rather large, hyaline spots, much larger than in Allophylax puncta- 

 tissiniHS, and they do not run together much, the costal area pale, 

 without spots. The fore wings are broad, the outer margin rounded, 

 but rather indented at ends of the veins ; the discal cell is about twice 

 as long as its pedicel, fork 1 extending its entire width back on the 

 discal cell ; the cubitus at the arculus is much farther from the branch 

 of the median than in Allophylax punctatissimus , all the apical cells 

 are broad at base. In the hind wings the apical cells are also broad 

 at base, the third broader than the fourth. 



Expanse 28 to 32 mm.

RHYACOPHILID^.

 Antennae pale, scarcely annulate with brown, basal joint also pale; 

 palpi pale, last joints rather darker; head pale, with long yellowish 

 hair, vertex darker, hairs on warts golden, ocellar warts hardly one- 

 half diameter apart ; thorax yellowish above, lateral lobes brown ; abdo- 

 men black, tip paler, with the extreme tips of genitalia black ; legs pale 

 yellow, spurs darker, in female the front and middle tibiae show a black 

 spot above just before the preapical spur, this spur on front tibiae is
