Hemerobius bolivari, new species. 



Pale yellowish, a black mark on each cheek, and tips of palpi black; 

 antenna? rather short. Wings hyaline; venation pale yellowish, inter- 

 rupted with dark-brown dots at rather long intervals, from each dark 

 dot there extends a brown streak obliquely out each side of the vein; 

 gradate series brown, and costal cross-veins brown at bases, a black 

 spot on the veinlet connecting lower branch of median to the cubitus, 

 and a smaller one at forking of cubitus; hind wings hyaline venation 

 pale. Fore wings slender, rounded at tip, costal area broad at base, 

 three radial sectors, a connecting veinlet from median to radius long 

 before origin of first radial sector; the connecting veinlet from the 

 lower branch of median to cubitus is shorter than the veinlet below it; 

 about six gradates in inner series and about seven in outer series; the 

 lower of inner series before the preceding one; hind wings with only 

 a few cross-veins. 



Expanse, 16 mm. 



From San Antonio, Colombia, 1,800 meters, February 



(Fassl). 



Hemerobius albipennis, new species. 



Head, antenna?, and thorax black, abdomen paler, legs very pale, 

 wings whitish hyaline, with hyaline venation, wholly unmarked; palpi 

 pale, with black tips. Antenna? rather long and slender; fore wings 

 elongate, tip rounded, costal area rather narrow, three radial sectors, 

 but the third is forked three times before stigma, and connected back 

 to the radius only once before stigma, and once at the outer gradate 

 series; the cross-veinlet from the lower branch of median to the cubi- 

 tus is shorter than the veinlet below it; six veinlets in the inner gra- 

 date series, last two interstitial or the last beyond preceding, seven 

 in outer series. Hind wings with few cross-veins. 



Expanse, 16 mm. 



From Paso del Ouindini, Ivinca, Colombia, 3,800 meters. 

 Distinct from all known species, by the contrasting colors of 

 wings and body. 



Family TRICHOPTERA. 



Macronema fraterna, new species . 



Closely related to M. argentilineata Ulmer, and lacks the first apical 

 sector in the hind wings; the fore wings are dark as in that species, 

 with the silvery line across in the stigmal region, but in this species 

 this line is plainly broader on the costal end, the apex of the wing is 

 also silvery for a short space, the inner margin of this space being- 

 convex (concave in M. argentilineata), and does not extend back 

 along the outer margin; there is no pale spot between the transverse
