ANT-LIONS, LACEWING-FLIES, d-c. 55 



ronga Kiver, about ten miles to the eastward of Wellington 

 Harbour. 



The expansion of the wings is slightly over 1$ inches, and the length of 

 the body about ^ inch. 



" Head above and pronotum yellowish ; ocelli large but not prominent, 

 approximate ; antennae pale-brown, the two basal joints and the base of the 

 third joint yellow. Meso- and meta-nota yellowish, clouded with fuscescent. 

 Anterior legs pale yellow, the tips of the tibise and tarsal joints brownish, 

 plantula brownish ; posterior legs mostly fuscescent. Abdomen ( ? ) fuscous 

 above, dull yellowish beneath ; apex obtuse, provided beneath with an 

 ovipositor (?), which appears to consist of two closely applied 2-jointed 

 pieces, the second joint directed backward from the first ; the posterior 

 margin of the seventh ventral segment produced in its middle into a 

 quadrate valve, from within which a cylindrical process, broad at its base, 

 is directed between the basal joints of the above-described apparatus. 

 Wings long-oval, sub-acute at the apex, with a very slight sub-apical 

 excision, ground colour pale grey ; anterior wings with the neuration 

 blackish and whitish irregularly alternate, giving a faint irregular tes- 

 selated appearance; pterostigmatic region long but ill-defined, whitish- 

 testaceous ; posterior wings almost without markings. Length of body, 

 13 mm. ; of anterior wing, 26 mm. ; its greatest breadth, i) mm. ; expanse 

 of wings, 54 mm. 



" Locality. — Otira Gorge. 



" Variety. — The head above and the pronotum more dusky, and the 

 black margins of the latter rather broader. Posterior legs wholly yellowish. 

 The anterior wings rather more strongly marked. Smaller. Expanse of 

 wings, ? 45 mm. 



"Locality. — Greymouth (?)." * 



This species may be easily recognised by its size, 

 which is intermediate between S. incisus (or citrinus) 

 and S. stella, also by its very slightly excised wings, and 

 their peculiarly dull tesselated appearance. The perfect 

 insect appears in January. It will probably be found to 

 frequent the edges of clear mountain torrents, in valleys 

 densely wooded with black birch (Fagus cliffortioides) ; 

 each of the three specimens at present taken appears 

 to have been found in a locality of this description. 



Genus DREPANEPTERYX, Leach (1835). 



"Antennae rather shorter than the body, moniliform, the basal joint very 

 robust ; maxillary palpi long and slender, labial palpi very short ; ocelli 

 wanting. Thorax broad. Wings broad; anterior pair much dilated and 

 rounded at the base, very numerous dichotomoin nervures united by two 

 longitudinal series on the costal area, and three somewhat irregularly placed 

 oblique series on the disk, exclusive of the pair common to all the family ; 

 the apical margin excised, and with a recurved apex ; the base of the inner 

 margin with a mucronated process. Posterior wings shorter, with fewer 

 nervures, somewhat lanceolate-acute, the hinder margin waved. Abdomen 

 compressed. Legs long and slender. 



" Distribution. — Europe, Asia, c&c." (Hutton). 



We have two species in New Zealand.
