Posterior wings subhyaline, tinged with brownish. Length of 

 the body, 8 mm. ; expanse of wings, 21 mm. 



Female. — Larger, the expanse of the wings being 30 mm. 



Locality. — WeUington. 



This insect, at first sight, has a somewhat deceptive re- 

 semblance to Hydropsyche fimbriata. 



Genus Pseud(econesus, McLachlan (1894). 



Male. — Antennae, palpi, and legs practically the same as 

 in CEconesus. Anterior wings without any costal fold, and no 

 defined groove ; the radius is confluent with the first apical 

 sector (in both sexes and in both pairs as in CEconesus) ; 

 upper edge of the discoidal cell excised (straight in CEconesus); 

 apical forks Nos. 1, 2, and 3 present, the others irregular ; 

 the sixth apical cell very much dilated at its base in a nearly 

 circular manner. Posterior wings with the apical forks 

 Nos. 1, 2, 3, and 5 present, the neuration apparently regular. 



Female. — The joints of the labial palpi shorter and broader, 

 the terminal joint almost spoon-shaped. In both pairs of 

 wings the apical forks Nos. 1, 2, 3, and 5 are present, and 

 the neuration appears to be normal and regular. 



Distribution. — New Zealand. 



Pseudoeconesus mimus. 



Pseudcsconesns mimus, McLachlan, Ent. Mo. Mag., 1894, 

 p. 239. 



Female. — Much like the same sex in CE. maori, but 

 slightly smaller ; the pale irrorations are larger and less 

 regular ; near the base of the third apical cell is a rather 

 large, rounded, pale spot, on each side of which is a some- 

 what conspicuous brown spot. On the antepenultimate ven- 

 tral segment is a very strong triangular tooth. The end of 

 the abdomen in dried specimens is very similar to that of 

 (E. maori. 



Locality. — Wellington. 



Pseudoeconesus stramineus. 



Pseudoeconesus stramineus, McLachlan, Ent. Mo. Mag., 1894, 

 p. 240. 



Male. — Stramineous or pale-testaceous. Anterior wings 

 pale-greyish, stramineous, closely irrorated with small whitish 

 spots, apical margin narrowly interruptedly fuscescent, inner 

 margin with four or five long fuscous lines alternating with 

 long pale spaces. Posterior wings whitish-stramineous, the 

 apical portion yellowish, fringes concolorous. Penultimate 

 and antepenultimate ventral segments of the abdomen each 

 with an acute tooth ; superior appendages lateral, quadrate,
