and two before it, another large irregular spot at the anal angle, broken 

 above by dark spots; some connected yellowish spots near base of wing, 

 and a number of small spots in discal part of wing. Hind-wing infuscated, 

 with two paler costal spots, one each side of the stigma. Venation prac- 

 tically the same as H. krcepelini, fork I in fore-wings as long as its pedicel, 

 the cross-veins behind base of the median cell not interstitial; in hind-wings 

 fork III is a little longer than in H. krcepelini. The lower appendages 

 of male are greatly thickened at tip. Expanse, 10 mm. 



From Los Banos, Philippine Islands (Baker). 



Ecnopsyche n. gen. 



A Hydropsychid, with distinct ocelli, venation of four wings very simi- 

 lar to Hydropsychodes and Ecnomus, especially in anal veins and short fifth 

 fork, spurs, 2, 4, 4. Fore wings with forks 1, 2, 3, 4, 5; hind wings with 

 forks 2, 3, 5; discal cell in both pairs closed, and in both a cross-vein from 

 discal cell to the radius. Antennae with long, slender joints; maxillary palpi 

 with joints two and three subequal and fusiform, fourth cylindrical and 

 equal to third, fifth twice as long as the fourth. 



This genus, by presence of ocelli, would go in Ulmer's family 

 Philopotamidce, but the venation is very different from any genus 

 therein, and more allied to true Hydropsyche. Stenopsyche has 

 venation also very different from Philopotamus, and so 'I cannot 

 consider the presence of ocelli as a family character. Likewise 

 Ulmer puts Ecnomus in the Polycentropidce because of the 3, 4, 

 4 spurs, but I agree with McLachlan in considering this genus 

 closely related to Tinodes, so that a family, Polycentropidce, based 

 on the spur formula, is to me, an unnatural association, and I 

 prefer to keep the family Hydropsy chidce in the old sense, with 

 many small groups based on various characters under it. It may 

 be well here to record the fact that the Hydropsy chidce differ from 

 other caddice flies in lacking bristles on the dorsum of the thorax, 

 fine hair only being present. 



Ecnopsyche reticulata n. sp. 



Yellowish; antennas very faintly darker at tips; vertex with rather sparse 

 golden hair; wings pale yellowish, reticulate with pale brown, which forms 

 many bands connecting the veins, rather dark at anastomosis, on the outer 

 margin. The wing is pale brown, with many small hyaline spots, indistinct 

 dark spots at the ends of the veins; venation yellowish; hind-wings hyaline, 

 vi-nation yellowish, especially near the costa. Legs pale yellow, very slen- 

 der, spurs more rufous; abdomen dull black, genitalia yellowish. Lower 

 appendages of male no larger at tip than at the base, tlic apical joint very 

 slender. Expanse, 15 mm.
