Psilochorema confusum. 



Psilochorema confiisum, McLachlan, Journ. Linn. Soc, vol. 10, 

 p. 210, pi. 2, fig. 10 (1870). 



Brown ; antennae yellow, indistinctly ringed with brown ; 

 basal joint with golden hairs. Anterior wings pale-brown, 

 with pale-yellow woolly clothing mixed with black ; an in- 

 distinct whitish wavy band before the apex and some pale 

 markings on the disk. Neuration very irregular in the male. 

 Posterior wings grey, subhyaline, iridescent, fringes grey. 

 Legs pale-yellow ; anterior and intermediate tibiae and tarsi 

 rather brownish externally. Abdomen brown, the apical 

 margin of each ventral segment broadly dingy-yellowish. 

 Inferior appendages in the male elongated and slender, bent 

 in the middle almost at right angles. In the female the 

 penultimate ventral segment bears a tuft of hairs, in the 

 middle. Length of the body, 4 mm. ; expanse of the wings, 

 15 mm. 



Locality. — Auckland. 



Family HYDEOPTILID^. 



Very minute, strongly pubescent and hairy, the wings 

 with numerous erect hairs. Palpi very hairy, simple in 

 structure, alike in both sexes. Antennae short and stout. 

 The larvae are without any external respiratory filaments, 

 and make cases usually movable (fixed in a Brazilian 

 species), formed of silk, to the exterior of which are some- 

 times attached minute grains of sand. The cases have a 

 slit at each end, and the larvae present their heads at 

 either indiscriminately. 



Genus Oxyethika, Eaton (1873). 



Antennae stout, the joints somewhat cup-shaped, slightly 

 longer than broad, the basal joint much longer than the 

 others. Maxillary palpi slender, the third to fifth joints long. 

 Ocelh present. Spurs 0.3.4. Anterior wings extremely 

 long and slender, the apices narrowly acuminate, clothing 

 very dense, costal fringes long ; neuration simple, the sector 

 ends in a long simple fork, as also does the upper branch of 

 the superior cubitus ; few, if any, transverse nervules. Pos- 

 terior wings exceedingly long and narrow, the apex longly 

 acuminate as in the anterior, very acute ; the costal margin 

 strongly elbowed near the base ; sector simple, superior 

 cubitus apparently with a small fork at the apex, a distinct 

 mediaii transverse nervule. 



Distribution. — Europe.
