34 NEW ZEALAND NEUROPTEBA. 



ATALOPHLEBIA NODULARIS. 



Leptophlebia nodularis, Eaton, Trans. Ent. Soc. 

 London, 1871, p. 81, pi. 4, fig. 20. Atalopklebia nodu- 

 laris, Eaton, Trans. Linn. Soc, Zool., vol. iii., p. 89, 

 pi. x., fig. 16e. 



" Imago. — Reddish -black, with translucent spaces on segments 2 to 5 of 

 the abdomen, one on each side of a dark median longitudinal line. Caudal 

 setae annulated. Wings vitreous, with the marginal and sub-marginal areas 

 reddish-brown. Legs reddish, the fore- and hind-femora with a black band 

 in the middle. Length, 9 mm. ; of the wing, 10-12 mm. ; of the setae, 16 mm. 



" Sub-imago. — Wings light grey, with dark neuration, with an ill-defined 

 irregular dark cloud enclosing a light space. 



" Localities. — Christchurch, Dunedin, and Wellington " (Hutton). 



I have been unable to identify this species with 

 certainty. 



ATALOPHLEBIA SCITA. 



Baetis scita, Walker, Cat. Neuroptera in Brit. Mus., 

 p. 570 (1853). Leptophlebia scita, Eaton, Trans. Ent. 

 Soc. London, 1871, p. 81, pi. 4, fig. 21. Atalopklebia 

 scita, Eaton, Trans. Linn. Soc, Zool., vol. iii., p. 90, 

 pi. x., fig. 16/. 



" Imago. — Dark brown, the segments of the abdomen broadly tipped with 

 black, the third to the sixth with a pair of translucent yellowish spots. 

 Setse annulated. Wings vitreous ; the fore-wings with a brown spot at 

 the base of the costa, and with less distinct ones in the marginal area at 

 the bulla, and in the pterostigmatic space. In the marginal area there are, 

 in the male, 7-8 cross-nervules before the bulla and 11-13 beyond it ; in 

 the female there are 9 before and 18 beyond the bulla. Length of body, 

 S C mm., ? 9 mm. ; of the wings, $ 7-8 mm., ? 11 mm. 



" Sub-imago. — Wings dark grey, with black neuration, the nervules of the 

 fore-wings edged with darker ; their scarcity behind the sub-costal in the 

 middle of the front of the disk gives rise to the appearance of a pale spot, 

 whilst the mutual approximation of three or four about the bulla, and 

 again in the midst of the pterostigmatic space, produces frequently two 

 dark spots. 



" Locality. — Christchurch " (Hutton). 



I am unacquainted with this species, which appears 

 to very closely resemble Deleatidium lillii in superficial 

 appearance. 



Genus DELEATIDIUM, Eaton (1899). 



"Distinguished as a genus from Leptophlebia by the 3 imago having 

 genitalia conformable in pattern to those of an Atalopklebia and by the 

 nymph having tracheal branchiae in the form of single, ovate, acute, penni- 

 veined, foliaceous lamellae. The cross-veinlets of the fore-wing, in the 

 typical species, are in two of the specimens widely spaced in places ; but 

 in the other specimens of the same and of the other sex the blanks are less 

 noticeable or are filled up. The name in Greek signifies a little bait " 

 (Eaton).
