BANKS: NEW NEUROPTEROID INSECTS. 313 



PERIPSOCUS PUMILIS, sp. nov. 



TYPE. M. C. Z. 10,808. Florida: Monticello (Scammell). 



Pale yellowish red, thoracic notum hardly darker, antennae brownish, wings 

 almost hyaline, faintly infuscate, stigma with dark basal spot; veins pale. 

 Head broad, with few erect bristly hairs; antennae minutely hairy, about two 

 thirds the length of the wing. Wings narrow, tip broadly rounded; stigma 

 slender; radial sector forks before end of stigma, the fork being longer than the 

 pedicel; median vein with short branches toward tip; median and radial 

 sector meet at one point. 



Length 1.7 mm. 



In general similar to P. californicus, but smaller, and lacks dark 

 spots at ends of veins, and fork of radial sector much longer, and 

 median forks farther out than in that species. 



PERIPSOCUS PERUANUS, nov. sp. 



TYPE. M. C. Z. 10,803. Peru: Lima, 21-30 August (H. S. 

 Parish). 



Pale brown; thorax above darker brown; legs pale brownish, scarcely 

 darker at the tips; wings uniform pale brown, the veins darker brown, stigma 

 hardly darker than rest of the wing, a dark dot at end of the anal. vein. Wings 

 rather short, and broadly rounded at tip, the stigma not its length from the 

 tip, rounded behind; the radial sector forks just beyond the band of the 

 stigma, the outer branch of the median vein arises a little beyond this, the 

 first branch opposite the bend of the stigma; the median and radial sectors 

 united for a distance equal to the width of the stigma; also about as far in the 

 hind wing. 



Length 2.7 mm. 



DYPSOCUS PARVULUS, sp. nov. 



TYPE. M. C. Z. 10,794. Straits Settlements: Singapore (C. F. 

 Baker). 



In general appearance similar to D. apicatus and D. coleoptratus; differs 

 from them in having the antennae very slender throughout. The head is 

 flattened, with short, dense hair, the antennae are pale brown, minutely hairy. 

 The fore wings have a broad dark stripe over most of surface, leaving the apical 

 costal region clear, but a dark band across the tip of the stigma, the posterior 

 margin is scarcely hyaline except in the areola postica and a little before it.
