PSEUDO-NEUROPTERA. 

 Tarn. PSOGIDj^. 

 Mtopsocus noy^-zealakdi^, Kolbe, Ent. Nachrichten, is, p. 

 145 (1883), = Psocus zealandicus, Hudson, Man. N. Z. Ent, p. 107> 

 pi. xvi, fig. 2 (1892). 



The t^'pes of Kolbe's species, in very bad condition (Wellington; 

 I believe from Mr. Hudson), are in my collection. There seems to be 

 no doubt that Mr. Hudson's insect is identical, but his figure (of the 

 perfect insect) leaves much to be desired. 



Fam. EPHEMERIDM. 

 Ephemera Hudsoni, n. sp. 



(? imago. Body castaneous (abdomen mutilated after its 4tli segment ; its 

 segmental divisions narrowly darker), paler beneath. Eyes liver-red. Legs pale 

 dingy yellowish ; anterior femora with a short blackish line internally, and their 

 tips, and those of the same tibise and tarsal joints, darker. Anterior wings vitreous, 

 iridescent, the costal margin as far as the radius, from close to the base to the extreme 

 apex, dark reddish-brown, otherwise these wings are quite without markings ; neu- 

 ration black, but the roots of the chief nervures and the cellules enclosed thereby, 

 are pale yellowish j pterostigmatic region with mostly two rows of irregular cellules, 

 most of the nervules being connected, the cellules of the lower row mostly larger. 

 Posterior wings vitreous, without markings, the dilated basal costal portion faintly 

 tinged with yellowish ; neuration black, principal nervures yellowish at extreme base. 



Length of body (?). Expanse of anterior wings, 41 mm. Length of anterior 

 wing, 19^ mm. 



$ suhimago. Body dull greyish-brown, without markings, save that the seg- 

 mental divisions of the abdomen are narrowly darker. Legs pale whitish-yellow, 

 the articulations blackish, and the last tarsal joint and claws also blackish or fuscous. 

 Outer setae long (the tips wanting), pale greyish-brown, finely pubescent ; middle 

 seta (in the example before me) rudimentary, shorter than the appendages, dilated 

 and rounded at the apex, consisting of not more than ten transverse joints. Append- 

 ages greyish-yellow, the long 2nd joint nearly straight, terminal two joints short, 

 subequal and slightly incurved. Anterior wings sub-opaque, pale greyish, with the 

 costal margin and neuration as in the imago, and in addition there are two oblique, 

 irregular, transverse, smoky-grey fasciae, one nodal at its origin, and not extending 

 to the inner margin, the other sub-stigmatical, and extending right across, the sub- 

 apical margin bordered with the same colour. Posterior wings concolorous with the 

 anterior, with a faint, smoky-grey, median, oblique fascia, and the apical portion also 

 smoky-grey. Length of body, 20 mm. Expanse as in imago. 



$ subimago. Almost entirely similar to the ^ subimago, but larger and more
