HuTTON. — On Neio Zealand Neuroptera. 235 



Family SEEICOSTOMATID^. 



Maxillary palpi of the male 2- or 3- jointed, ordinarily very 

 pubescent or pilose, and always formed in quite a different 

 manner from those of the female ; varying greatly according 

 to the genus. Larva with non-fasciculate respiratory filaments ; 

 the case free. 



Genus fficoNESus, McLachlan (1862). 



Male. — Head quadrate ; antennae about the length of the 

 wings, basal joint short and rather thick, not so long as the 

 head. Maxillary palpi oval-elongate, much swollen, curved 

 up in front of the head, their apices when viewed from above 

 appearing as two rounded tubercles between the antennae, 

 moderately hairy. Labial palpi with the basal joints short, 

 the second and third of equal length, long. Anterior tibiae 

 with two short spurs ; intermediate and posterior, each with 

 four long unequal spurs. Anterior wings rather short and 

 broad, very slightly hairy, the costa much arched, apical 

 margin almost straight ; the costa from the base to the ptero- 

 stigma is narrowly folded inwards ; discoidal cell long and 

 narrow ; the superior cubitus does not fork before the anasto- 

 mosis, 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-joiuted, 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. 



Distribution. — New Zealand. 



CEconesus maori. 



CEconesus maori, McLachlan, Trans. Ent. Soc. London, 1862, 

 p. 3; Jour. Linn. Soc, vol. 10, pi. 2, fig. 1. 



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.
