I have two examples before tne from Wellington (^Hudson, " Nos. 

 lb and 11 "), and in referring them to Pseudceconesus (in the absence 

 of the cJ ) have been principally guided by the form of the discoidal 

 cell. 



Pseudceconesus stramisteus, n. sp. 



S . Much paler than Ps. mimus, stramineous or pale testaceous. Anterior wings 



pale greyish-stramineous, closely irrorated with small whitish spots, the pubescence 



greyish and stramineous intermixed (no dark spots in the 3rd apical cellule), apical 



margin narrowly fuscescent, slightly interrupted with the ground colour, and on the 



inner margin are four or five long fuscous lines alternating with long pale spaces. 



Posterior wings whitish-silky-stramineous, the apical portion more yellowish, fringes 



concolorous. On the ante-penultimate ventral segment is a long and strong narrow, 



testaceous, acute tooth, and another similar, but rather shorter, on the penultimate. 



Last dorsal segment concealed (in the example before me) ; superior appendages 



lateral, quadrate, furnished with long pale hairs. Intermediate appendages (or 



upper penis cover ?), viewed from above, consolidated into a broad elongate plate, 



canaliculate above, deeply notched at the apex, forming two obtuse apical points 



furnished with very long pale hairs. Inferior appendages 2-branched, the branches 



distant, both apparently stout and cylindrical, curved in such a manner as to leave 



a semicircular space between them. 



Length of body, 7 mm. Expanse of wings, 28 mm. 



One (^ from Wellington {Hudson, " No. 126 "), which I consider 

 the type of Pseudceconesus. 



? . As in the $ , but the body darker, and the anterior wings with a more 



decided yellowish tint ; the pale and dark spaces on the inner margin less distinct. 



A sharp, broad, triangular tooth on the ante-penultimate ventral segment. 



Margin of last dorsal segment nearly straight, and slightly excised in its middle. 



Tubular piece forming two small, broad, triangular obtuse lobes, if viewed laterally, 



but open above and beneath. 



Length of body, 10 mm. Expanse of wings, 33 mm. 



One example from Mount Arthur, 2800 feet, January 19th {Mey- 

 rich) ; a second much smaller example from the same locality but at 

 4500 ft. elevation, expands to only 20 mm., it agrees with the larger 

 in all essential points, and the dwarfing is probably due to altitude. 



Although the sexes above described are not from the same locality, 

 I have coupled them on account of colour-likeness, it seeming to me 

 very improbable that the ^ described as stramineus can be of the same 

 species as the $ described as mimus. Feeling that there is yet a good 

 deal to clear up in these allied forms, and that it could only be satis- 

 factorily done by local observers, I have quoted the numbers on the 

 specimens forwarded to me by Mr. Hudson.
