42 NEUROPTERA OE NORTH AMERICA. 



J* Imago. Fulvous, spotted with fuscous; antennae gray, basal 

 article brownish-black ; head dusky in front, beneath yellow ; pro- 

 thorax narrowed in the middle, above triangularly tuberculated, 

 each side with a fuscous stripe confluent upon the disk ; abdomen 

 brownish-black, dorsum each side with an interrupted yellow stripe; 

 anterior feet entirely fuscous, posterior ones brownish-yellow, un- 

 guiculi fuscous; seta3 long, fuscous, the apex of the articles with a 

 very small whitish annulus; intermediate seta very short; anal ap- 

 pendages fuscous ; penis two-parted, fuscous, apex unguiculated, 

 recurved; wings subhyaline, anterior ones with the costal margin 

 fuscous; veins black, some transverse ones bounded with black; 

 posterior wings margined exteriorly with fuscous, discoidal trans- 

 verse veins covered with black. 



<£ Subimago. Like the imago, but with the body opaque, grayer, 

 the feet obscurer, the wings opaque gray, the anterior ones hardly 

 colored upon the costal margin, the posterior ones more broadly 

 margined. • 



9 Imago. Similar to the male; the whole body paler, more 

 fulvous, setae and feet paler; the intermediate seta very short; the 

 anterior wings have the costal margin paler. 



9 Subimago. Similar to the imago, the body opaque ; brown- 

 ish-gray, feet and setae brownish-black, wings opaque gray, 'the 

 anterior ones with the costal margin of the same color, the poste- 

 rior ones with a brownish-black margin. 



I possess another female subimago, a younger specimen. The 

 body, feet, and setae are much diluted and pale-colored, the margin 

 of the posterior wings is of the same color, pale. It is hardly 

 different.

 Chicago (Osten Sacken); St. Martin's Falls, Albany River,

Male imagines, from Chicago seem to differ a little, the colors 

 are much paler, the apex of the penis is incurved, the basal half 

 of the antennas is black, the setae yellowish and the apex of the 

 articulations has a fuscous ring. P. bilineata from Washington 

 and P. limhata from New Orleans certainly are distinct species ; 

 the species from Chicago is colored very much like P. Iimbata, but
