dark; the antennae dark^ and narrowly, indistinctly annulate with 

 pale; the mesonotum is pale, with a median black stripe undivided by 

 pale; the pleura are brown, with long white hair; the fore legs are 

 mostly black, the tibiae with some pale bands, other legs paler, and all 

 thickly clothed with long white hair; abdomen dull black. Wings 

 hyaline, in general appearance like A. fallax, the pterostigma being 

 dark, and in the fore wings an oblique subapical mark, but the radius 

 is not punctate, only interrupted at long intervals by black; there are 

 nine cross-veins before radial sector in fore wings, none of them 

 crossed (several crossed in A. fallax) ; there are two series of costals 

 beyond the basal fourth of wing ; in the hind wings there are six or 

 seven cross-veins before the radial sector, and the anal runs into the 

 branch of the cubitus. 



Expanse 96 mm., width of fore wing 12 mm.

Brachynemurus camposi, n. sp. 



Face yellowish, a brown interantennal mark, vertex mostly brown ; 

 pronotum dark brown, with a narrow median yellow line, and a faint 

 yellowish streak each side behind; thorax brown, with a narrow 

 median yellow stripe, and some spots each side; abdomen yellowish 

 brown, apparently unmarked ; legs brownish yellow, the tarsi mostly 

 black, the tips of the tibiae infuscated, most of the bristles on front 

 legs snow-white, some white ones on hind legs, others black. Wings 

 hyaline, veins mostly brown, only indistinctly interrupted with pale, 

 subcosta and radius not marked, pterostigma not prominent. Antennae 

 short, and with very large knobs ; legs short, anterior tarsi fully as 

 long as the tibiae; the basal joint of tarsus short, but much longer 

 than the middle ones, apical joint long, spurs as long as two tarsal 

 joints. Wings extremely slender, sub falcate at tips, three cross-veins 

 before radial sector in fore wings, in fore wings the anal runs by the 

 branch of cubitus and ends near end of that vein, but in hind wings 

 the anal turns down just beyond fork of cubitus. 



Expanse 34 mm., width of fore wing 3.5 mm.

Brach5memurus eiseni, n. sp. 



Similar in many respects to B. sackeni, and in a paper on Neuroptera 

 from Baja California I considered it that species. It differs, however, 

 in a number of points, and especially in the male appendages. The 

 vertex has three large spots behind, one of them median, and two 

 each side in front ; the thoracic marks are more united than in B. 

 sackeni, but on the same plan, the dots on the mesoscutellum larger 

 than in that species and situated more nearly in front; the abdomen 

 has the pale spots of a snow-white color, and they are present on all
