21. Stenosmylus citrinus, n. sp. 



S, forma S. incisi. Citrinus. Frons obscurior, supra nigricans. Thorax utrinqiie 

 niger. Tibiae anticse et intermediiB (femoraque postica) ad apices et in medio fusco 

 semicinctffi. Alae anticce pnnctis nigris conspersae ; macula discali sabapicali, 

 nonnullisque parvis ad marginem apicalem et internum albidis, nigro marginatis ; 

 posticse pallidiores, punctis nigris subobsoletis solum ad costam, maculis albidis 

 nuUis. Abdomen infuscatum. Long. corp. 7'" ; exp. alar. 27'". 



The whole insect is of a delicate citron colour, excepting the abdomen, 

 which is infuscate ; but the colour of this part is probably changed in dry- 

 examples. On the face 'the colour becomes obscured, and below the base of 

 the antennae it is blackish. On the pronotum anteriorly there is a trace of a 

 black median longitudinal line, and the sides are broadly black, with black 

 hairs ; the meso- and metanota have the sides broadly infuscate, bordered by a 

 black line. The anterior and intermediate tibise have a black spot at each end 

 and in the middle ; the posterior femora are s-omewhat infuscate, darker at 

 each end, and with a ti-ace of a black spot in the middle ; all the legs are 

 clothed with citron-coloured hairs. The anterior wings have many small 

 black dots, those below the radius, and two discal ones, lai-ger than the others ; 

 at the end of the first branch of the sector and the upper cubital vein, before 

 the apex, is a conspicuous irregular whitish spot margined with blacky and 

 along the excised apical margin and on the inner margin are smaller whitish 

 spots, margined with blackish internally, or with a blackish dot on each side ; 

 the sector has sixteen principal branches ; the inner series of gradate nervules 

 is rudimentary. The posterior wings are paler than the anterior, without 

 whitish spots ; and the black dots ai'e only faintly indicated on the costal 

 margin. 



A very beautiful insect, of the same form as S. incisus.

I'ound also in Australia without appai-ent specific difi"erence. Most of the 

 New Zealand examples (but not all) pertain to the variety indicated at fig. 4* 

 with a large whitish costal spot in the fore wings ; but at present I see nothing 

 to indicate that these form a distinct species. 



23. Drepatwpteryx humilis, M'Lachlan. 

 Drepanopteryx humilis, M'LacM. Journ. of Entom. vol. ii. p. 116, pi. vi. fig. 5.* 



Found also at Moreton Bay. The smaller size seems to indicate that this 

 is not a form of D. instabilis. 



•]■ According to the characters of the genera Drepano23teryx and Megalomus as laid 

 down by Brauer {cf. ' Verhandl. zool.-bot. Gesellschaft in Wien,') 1866, p. 987, the two 

 New Zealand species and the Australian Z>. binocidus ought perhaps to be placed in the 

 last-named genus.
