46 AMERICAN NEUROPTERA. 



Many specimens from various localities in the Eastern and South- 

 ern States throughout the summer; one of our most abundant 

 Hemerobiids. I have bred the larvse several times ; they occur on 

 various deciduous trees, feeding on plant-lice.' 



Micromns Tariolosns Hagen.— Head pale yellow, a dark line on mid- 

 dle, connected to a line on base of clypeus, antennal sockets margined with dark, 

 and vertex dark in middle; antennse yellowish; thorax and abdomen brown; 

 legs pale yellow; tibiae marked with brown on outer sides. Wings hyaline, with 

 brown clouds and streaks or bands, most prominent on outer half; venation 

 brown, with pale spots ; margin alternately brown and white; hind wings hya- 

 line, with brown venation. Wings very slender ; four radial sectors; the gradate 

 series very irregular, and each veinlet more than its length from any other. Ex- 

 panse 13 to 15 mm. 



Specimens from Denver, Fort Collins and Salida, Colorado; Pull- 

 man, Washington ; Pecos and Mesilla, New Mexico ; and various 

 places in Arizona. Hagen had one specimen from Denver, Colo- 

 rado. They have mostly been taken in June and July.

 anteiuise pale; legs pale; abdomen brown. Wings hyaline, venation almost 

 hyaline, with a few brown dots, cross-veins more brown, two of the outer gradate 

 ones and the basal cross-vein more heavily brown, and margined with brown, a 

 few brown spots along posterior margin ; hind wings pale, venation pale in basal 

 half, brown beyond. Wings slender; the gradate series very irregular, and each 

 veinlet more than its length from any other ; four radial sectors. Expanse 13 to 

 15 mm. 



Specimens from Shreveport, Louisiana; Biscayne Bay, Florida; 

 and Falls Church, Virginia, in June, on ground near base of grass

Since the above paper was written (November, 1904) there has 

 just come to hand (July, 1905) Bull. No. 86 of the New York 

 State Museum, with a table of genera of Hemerobiidse, by J. G. 

 Needham. He separates H&merobius amiculus in a new genus — 

 Palmobius, on the same venational point as myself. However, he 

 has not noted the absence of apical cross-veins in hindwings, nor 

 their number in forewings. He also separates from this a new 

 genus, Spadobius, for what he calls the H. occidentalis Fitch. His 

 figures of the wing, however, shows it is not that species at all, and 

 in fact is closely allied to S. amiculus, and quite probably a speci- 

 men of that species. My series of this species shows still greater
