GRAC. PYROCHROMA, N. sp. 
9-10 mm. Head and thorax bright-yellow. Face and maxil- 
lary palpi clear-white. Labial palpi white, second joint fuscous 
at apex, terminal joint with a median fuscous ring, beyond this 
yellowish. Antenne longer than forewings, grey, basal joint 
yellow above, white beneath. Abdomen above fuscous, deepen- 
ing in shade posteriorly, beneath white. Legs, amerior femora 
white, tibize and tarsi fuscous ; middle tibie and first two joints 
of tarsi densely thickened with scales, reddish-fuscous, terminal 
joints not thickened, paler; posterior tibise and tarsi whitish. 
Forewings glossy reddish-purple, with darker purple dots, forming 
an interrupted line along costa; a bright-yellow dorsal streak 
from base, terminating abruptly at anal angle, edged with black, 
nearly half breadth of wing, indented to half its breadth, close 
to base and approximately at one-third, two-thirds, and at anal 
angle ; costal edge from near base to apex occupied by a narrow, 
blackish-purple, irregularly-thickened line; internal to this is a 
narrow yellow line, sometimes suffused with reddish-purple ; and 
internal to this again a longitudinal line in disc from two-thirds 
nearly to apex, with a metallic-blue lustre, narrowly bordered on 
each side with blackish ; a brilliant-metallic spot at apex, and a 
yellow hindmarginal line continuous with that on inner margin ; 
cilia whitish on costa, with a dark apical spot showing in certain 
lights a vivid-blue iridescence, on hindmargin reddish-fuscous, 
becoming paler towards anal angle, thence dark-grey. Hind- 
wings and cilia dark-grey. 
This brilliant insect rests with its head appressed to the sur- 
face. Except in the thickening of the basal tarsal joints of the 
middle pair of legs, it appears to agree structurally with this 
genus. I have not examined the neuration. 
Brisbane ; five specimens on a fence in August and September. 
GRAC. ALBISTRIATELLA, 0. sp. 
7-8 mm. Head, thorax, face, and palpi white. Antennz 
dark-grey. Abdomen above fuscous, beneath reddish-fuscous. 
Legs, anterior and middle pairs fuscous, posterior whitish; middle 
tibie not thickened. Forewings pale ochreous-grey, with a white 
line along inner-margin, and five costal and three dorsal white 
streaks ; first costal streak at one-third, outwardly oblique, nar- 
rowly produced along costa half way to base; second from 
beyond middle, very oblique outwardly, produced as a very slender 
line to margin of fourth streak ; third shortly beyond second, 
outwardly oblique, occasionally connected by a slender line from 
its base with second; fourth lustrous, coalescing with third dorsal 
to form an outwardly curved, slender, black-margined fascia from 
costa to anal angle ; fifth a mere dot beyond fourth; first and
