hairs on the lateral margin. Meso- and meta-nota yellowish, clouded with fusoesoent. 

 Anterior legs pale yellow, with fine, short, dark hairs, the tips of the tibise and of 

 the tarsal joints brownish, plantula brownish (intermediate legs wanting) ; posterior 

 legs mostly fuscescent, but the base of the femora and tibiae is somewhat yellowish. 

 Abdomen ( $ ) fuscous above, dull yellowish beneath, sparingly clothed with pale 

 pubescence : apex obtuse, provided beneath with an ovipositor (?) which appears to 

 consist of two closely applied two-jointed pieces, the second joint directed backward 

 upon the first ; the posterior margin of the 7th ventral segment produced in its 

 middle into a quadrate valve, from within which a cylindrical process (broad at its 

 base) is directed between the basal joints of the above described apparatus. 



Wings long-oval, subacute at the apex, with a very slight subapical excision. 

 The ground-colour is very pale grey, somewhat shining : in the anterior wings the 

 neuration is blackish and whitish alternately, but in an irregular manner, closely set 

 with minute black tubercles, whence arise black hairs ; some of the black transverse 

 nervules are faintly clouded, giving a faint irregular tessellated appearance ; the 

 margins all round are alternately whitish and dark in an irregular manner ; there 

 are faint dark spots on the transverse nervules between the radius and sector at their 

 commencement, also along the lower cubitus, and the external series of gradate 

 nervules form a somewhat curved dark line ; pterostigmatic region (in both pairs) 

 long but ill-defined, whitish-testaceous ; costal nervules irregular, some simple, some 

 with a small fork at the costal end, or forked and each branch again forked : posterior 

 wings almost without markings, save slight nebulosity occasioned by the grouping of 

 the black nervules, which are less numerous than in the anterior, and the black 

 tubercles are fewer in number and scarcely evident. 



Length of body, 13 mm. Expanse of wings, 54 mm. ; length of anterior wing, 

 26 mm., greatest breadth, 9 mm. 



I have one $ labelled " Otira Gorge, on window at light." 



Var. Smaller (expanse, 45 mm.). The head above and pronotum more dusky, 

 and the black margins of the latter rather broader. Posterior legs wholly yellowish. 

 The anterior wings rather more strongly marked, the spots under the radius and 

 along the lower cubitus rather more distinct. 



One $ without special indication of locality, but which may 

 possibly have come from Greymouth. The difference from the type 

 is very slight, and any importance attached to the slight discrepancies 

 mentioned would probably disappear with more materials. 



Stekosmtlus i]srcisus, McLach. — I possess this species from 

 Otago {Oxley), Waitara, and Wellington {Hudson). According to 

 Mr. Hudson it is rare in the neighbourhood of Wellington. 



Stenosmtlxjs citeinus, McLach. — This insect is apparently 

 liable to variation, and perhaps from local causes, so far as I can judge 

 from the three specimens in my collection. The precise locality of 

 the type specimen is uncertain. A second, from Wellington (Hudson) 

 has the anterior wings more strongly marked and the ground somewhat
