$ . The proboscis in the £ has short hairs on its apical half, 
and is testaceous, with the apex black (Arribalzaga). 
Habitat. —Buenos Ayres (Arribalzaga) ; Sao Paulo (Dr. 
Lutz). 
Observations.— Through the kindness of Dr. Lutz I have been 
, enabled to examine a specimen of this beautiful little species, 
which may be taken as the type of the genus. The broad scales 
on the thorax are brilliant pale blue, and can easily be seen with 
the naked eye. This species can at once be told from its 
neighbours, U. geometrica and U. saphirina, by the mid thoracic 
blue line ending abruptly before the scutellum. 
Arribalzaga described this species from the Argentine. Dr. 
Lutz has only met with it, so he informs me, in one locality at 
Sao Paulo, so that it may be a local species, and at present is 
only known to occur in South America. 
2. Uranotaenia geometrica. n. sp. (Lutz MS.) 
(Fig. 129, PI. XXXIII.) 
Thorax testaceous brown, with two more or less distinct 
paler parallel lines, covered with scattered thin bronzy-brown 
scales, with a light blue line before the roots of the wings, a spot 
in the middle near the bare space in front of the scutellum, and 
another blue spot on the mid scutellar lobe and pale blue 
prothoracic lobes, and also two blue spots on the head. 
Abdomen black, with apical median triangular white patches. 
Legs blackish, with apical white bands, the last two hind tarsi 
being all white. 
9 . Head covered with flat black scales, rather ochraceous 
behind, and with brilliant blue ones at the sides and along the 
eyes; antennae brown, basal joint and base of the second joint 
Bright clear yellow ; palpi very small, brown scaled ; clypeus deep 
rich brown, shiny; proboscis as long as the whole body, swollen 
at the apex, brown at the base, dull metallic green, then purple 
at the apex. 
Thorax bright testaceous brown, with two paler parallel lines, 
somewhat darker between than at the sides, covered with 
scattered narrow deep bronzy scales, which under the microscope 
present a beautiful appearance; the middle of the scales appears 
as a dark line bordered with a narrow golden rim ; in front 
of the roots of the wings is a long patch of brilliant pale
