OF WASHINGTON, VOLUME XV, 1913 171 



that the total fauna in these groups of insects will amount to 

 several hundred species. The Psocidss and the Trichoptera will 

 be particularly rich in new species, while the several families like 

 Panorpidse and Coniopterygidae as yet unrepresented will be found 

 to occur in several species. 



PSOCIDJ1. 

 Myopsocus enderleini Bks. 



From Los Banos. 



Caecilius sj>. 



Two specimens from Los Banos; a plain unmarked species. 



Psocus bakeri n. sp. 



Markings in general similar to P. cosmopierus, especially the apical 

 band of wings, the basal band runs obliquely across up to the radius, and 

 is very broad behind. The stigma is prominently, uniformly reddish (not 

 yellowish), and behind it is angulate. The first long joint of the antenna is 

 (except tip) pale yellow, not at all brownish; legs pale, tips of tibiae and tarsi 

 blackish. The radial sector and the median vein are united only at a point, 

 and in some cases even connected by a short cross-vein. 



From Los Banos, Philippines (Baker), on bark of tree in forest. 

 Because of the shape of the median cell, and of the angulate stig- 

 ma, and slightly different markings I think it is a separate species 

 rather than a variety of P. taprobanes, these characters hold in all 

 the numerous specimens. It is a size smaller than the Javan P. 

 taprobanes in my collection. 



Taeniostigma bimaculata n. sp. 



Very pale yellowish throughout, with two large shining black spot.s on 

 t IK- mesonotum, one on each side lobe; antennae deep black and black haired, 

 basal fifth of the fourth (and others beyond) joint is white; no spot on head ; 

 last tarsal joint black, rest of legs pale. Wings with the lower border of 

 the stigma brown (like T. ingens), the cubital vein also black and black 

 bordered; the median cell much broader at tip than in T. ingens, and 1 1n- 

 median and radial sector united for a longer distance than in that species 

 the "areola postica" has a very narrow base above on the median vein, 

 scarcely one-half as long as that of the apical cells; radial sector forks :i 

 little before last branch of the median. Length, 7 mm. 



From Los Banos, Philippines (Baker). 



PERLID.E. 

 Neoperla Clarissa Bks. 



From Los Banos.
