CEcoNEStrs MAOEi, McLach. — <? . There is a small triangular acute tooth on 

 the ante-penultimate ventral segment. Last dorsal segment narrow ; from its upper 

 edge arise the superior appendages in the form of two narrow transverse lobes, con- 

 tiguous in the middle of the margin, their outer edge furnished with long and strong 

 pale hairs j intermediate appendages (upper penis cover ?) long and flattened, united 

 for more than half their length, and then forming two branches, each oblique at its 

 apex, leaving a deep triangular excision between them. Inferior appendages two- 

 branched, the upper branch long, cylindrical and obtuse, bearing long pale hairs, 

 lower branch attenuate at the apex, which is curved downward. 



$ . Larger (expanse, 30 mm., as against 26 mm.). In the anterior wings the 

 pale irrorations are smaller and more evenly distributed. A sharp triangular brown- 

 tipped tooth on the ante-penultimate ventral segment. Last dorsal segment in the 

 form of a triangular plate ; below it is a tubular piece, truncate at its apex, whence 

 (viewed laterally) a narrow rounded valve proceeds on either side, projecting slightly 

 beyond the tube. 



I have males from Wellington {Hudson, " Nos. 1 and 11 ") ; the 

 only $ bears no special indication of locality. 



PsEUDffiCONESUS, It. g. 



The species of this genus resemble (Econesus in a very remarkable 

 manner, but the neuration of the ^ is quite different. The characters 

 here given are mainly comparative. 



(? . Characters of antennae, palpi, legs, &c., practically the same. In the anterior 

 wings there is no costal fold and no defined groove (present in (Econesus) ; the radius 

 is confluent with the first apical sector (in both sexes and in both pairs, as in CEco- 

 nesux) ; upper edge of discoidal cell excised (straight in Q^conesus) ; apical forks 

 Nos. 1, 2 and 3 present (irregular afterwards), the 6th apical cellule very much dilated 

 at its base in a nearly circular manner. In the posterior wings apical forks Nos. 1, 

 2, 3 and 5 are present, and the neuration is apparently regular (but abnormally 

 irregular on one side in the only male before me). 



? . The joints of the labial palpi shorter and broader, the terminal joint almost 

 spoon-shaped. In the anterior and posterior wings apical forks Nos. 1, 2, 3 and 5 

 are present, and the neuration appears to be normal and regular. 



It appears to me probable that (Econesus and Pseudoeconesus may 

 have aiEnity with the group of genera represented by Goera, Silo, &c. 



PSEUD(EC0NESUS MIMUS, n. sp. 



? . Almost precisely similar to the same sex in CE. maori, but slightly smaller. 

 In the anterior wings the excised upper edge of the discoidal cell (mentioned in the 

 generic characters) is a good structural definition ; the pale irrorations are larger 

 and less regular (more as in the J of CE. maori) ; near the base of the 3rd apical 

 cellule is a rather large rounded pale spot, on each side of which is a somewhat con- 

 spicuous brown spot (wanting in CE. maori). 



On the ante-penultimate ventral segment is a very strong triangular tooth. 

 End of abdomen very similar (in dried examples) to that of CE. maori.
