62 NEW ZEALAND NEUBOPTEBA. 



margin almost straight ; the costa from the base to the pterostigma is nar- 

 rowly folded inwards ; discoidal cell long and narrow ; the superior cubitus 

 does not fork before the anastomosis, and from this cause there are only 

 eight apical cells ; the anastomosis is complete and very oblique from the 

 third apical cell ; the lower part is not connected with the inner margin by 

 a transverse nervule, and the last apical cell is continued from the apex 

 to near the base of the wing, the apical portion being very broad ; near the 

 base of the third apical cell in all four wings is a small round hyaline spot. 

 Posterior wings broad, folded, the discoidal cell short and triangular. 



" Female. — The maxillary palpi are 5-jointed, the basal joint very short, 

 the second slightly longer, the third to the fifth still longer and nearly equal. 

 The neuration of the anterior wings is regular, and in the posterior wings 

 there are two additional apical forks.

(ECONESUS MAORI. 



CEconesus maori, McLachlan, Trans. Ent. Soc., 

 London, 1862, p. 3; Jour. Linn. Soc, vol. 10, pi. 2, 

 fig. 1 ; Entom. Mo. Mag., 1894, 239. 



This species is recorded from Auckland, and I have 

 captured a few specimens in the vicinity of Wellington. 

 It has also occurred at Ophir in the South Island, but 

 does not seem to be generally common. 



The expansion of the wings is 1^ inches. 



" Male. — Antennae pale-ochreous ; eyes blackish, slightly reticulated with 

 brassy; head, thorax, and abdomen reddish-brown; legs reddish-ochreous; 

 anterior wings rusty-brown, thickly irrorated with whitish spots, which are 

 larger towards the base ; on the inner margin are three elongated whitish 

 spots, alternating with others of the dark ground-colour. 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. 



" This insect, at first sight, has a somewhat deceptive resemblance to> 

 Hydropsyche fimbriata " (Hutton). 



The perfect insect appears from October till April, 

 and frequents the foliage on the margins of rivers and 

 streams. It is sometimes attracted by light. 



Genus PSEUDCECONESUS, McLachlan (1891). 



" Male. — Antennae, palpi, and legs practically the same as in (Econesus. 

 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 

 (Econesus) ; 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 ter- 

 minal 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.
