HRIA SODALIS, n. s. _Mas._ Cyanea, capite aurato, antennarum
articulo tertio fusiformi, thoracis lateribus purpureo-viridibus,
pectore ventreque argenteis, abdomine maculis lateralibus argenteis,
alis cinereis, apice posticeque nigricantibus.

_Male._ Blue. Head brightly gilded, vertex and hind part silvery,
underside with white hairs; mystax with four long black bristles, and
with several gilded bristles; third joint of the antennae
elongate-fusiform; sides of the thorax varied with green and purple;
abdomen with spots of silvery tomentum along each side, underside and
pectus silvery; wings grey, black towards the tips and along half the
length of the hind border; halteres white. Length of the body 7 lines;
of the wings 13 lines.

The veins of this species are hardly different from those of _L.
consobrina_ in structure, excepting the third externo-medial, which is
united to the fourth nearer the border.

30. LAPHRIA COMES, n. s. _Mas et Foem._ Viridi-cyanea, capite aurato,
antennarum articulo tertio fusiformi, pectore ventrisque lateribus
argenteis, abdomine viridi (mas) aut purpureo-cyaneo (foem.) maculis
lateralibus argenteis, alis nigricantibus basi cinereis.

_Male and Female._ Greenish blue. Head brightly gilded, hind part
silvery; mystax with six long black bristles; third joint of the antennae
elongate-fusiform; pectus with silvery tomentum; abdomen green in the
male, purplish-blue in the female, with silvery spots along each side,
underside with two silvery stripes; wings blackish, grey at the base and
along the costa for more than one-third of the length, veins and
halteres black. Length of the body 6--6-1/2 lines; of the wings 11-12
lines.

This may be only a small variety of _L. consobrina_; but the wings are
not darker towards the costa as in that species, and the first
branch-vein is much more straight.
