GENUS UKANOT^NIA 491 



Head clothed with flat scales of a dark brown and deep ochreous 

 brown colour on the occiput, a small blue patch on each side close to the 

 eyes, behind are short black upright forked scales ; antennae brown, 

 with narrow pale rings, basal joint bright pale reddish-yellow, pro- 

 boscis and palpi black, the latter very small, especially in the $ , the 

 former expanded towards the tip. Pleurae pale yellow, with a prominent 

 azure-blue spot over the fore coxae. Wing scales closely resembling 

 those of TJ. geometrica, and like it, with azure-blue patches at the base 

 of II and V. Legs dark brown, with small white knee-spots, and apical 

 rings on the tibiae. The proportion in which the contiguous abdommal 

 segments contribute to the pale bands is most irregular, some of them 

 being mainly formed by the apex of the segment in front, while 

 others are almost purely basal, but on the venter the pale bands are 

 more regularly apical. It may be distinguished from XJ. geometrica 

 by its more complete abdominal banding, and by only the fifth, 

 instead of the last two tarsal joints being entirely white. Length. — 

 About 2*5 mm. 



Habitat. — Brazil and Argentina, South America ; and I have recently 

 received two ^ specimens from Dr. Forrest, of Antigua, whose remarks 

 on the larvae of JJranotcenia may be taken to refer to those of this 

 species. 



5. URANOTiENIA ARGYROPODA (Walker). ( " List," p. 2.) 



Last two hind tarsal joints and apex of next yellowish, but 

 with the tarsi apparently otherwise unadorned, beyond a broad 

 band consisting of all the fourth fore tarsal and parts of the joints 

 above and below it, which appear pale in certain lights. Thorax 

 (much denuded) ferruginous, with hair-like brown scales and 

 patches of flat blue scales on the prothoracic lobes. Abdominal 

 segments dusky, with white lateral apical patches. A large 

 mosquito. Venation of wing as in Erctmapoditcs. 



$ . — Head black with azure-blue orbits ; palpi black, with a white 

 patcli m the middle ; proboscis black ; scutellum ochreous, with dusky 

 flat scales. Pleuraj brown, with white patches. Legs brown, with the 

 femora yellowish, white at apex and base, and with a dull white, sub- 

 apical spot. Venter brown with apical white borders to its segments. 

 Length. — 7'5 mm. 



Habitat. — New Zealand. 



Observations. — In the absence of the male it is impossible to deter- 

 mine the generic position of this species, the type of which is in none too 

 good a condition, but personally I do not think it can belong to the present 

 genus, all the other species of which are very small, while this is above 

 the average size of most genera ; in addition to wliich, the venation of 

 the wings is as different as it well can be, and I should prefer to place 

 it provisionally in Eremapodites, the wing scales of which much resemble 

 those of Uranotainia.
