above as well as a narrow border of the collar metallic bluish-green; abdomen above dark brown. Forewing 
ochreous-yellow, the basal two thirds of the costal margin metallic bluish-green; a band from the base along 
the proximal margin is expanded below the cell to a large spot, and another wedge-shaped, postmedian spot 
is coloured the same. Hindwing light ochreous-yellow, an apical spot dark brown. Length of forewings: 18 mm.

118. Genus: Calamidia Btlr. 
Proboscis well developed; male palpi much longer and more slender than in the $; abdomen roughly 
haired. Forewing long and narrow, with a curved costal margin; the middle radial vein is absent; accessory 
cell present, only the 1st subcostal comes separately from the cell; on the hindwing the middle radial is likewise 
absent, the others rise unpetioled. In addition to the only species formerly known from Australia, 5 more have 
been recently described from New Guinea. 
C. hirta Wkr. (— salpinctis Meyr.) (15 e). The light ochreous-yellow forewing is densely dusted with hirta. 
a. brownish grey, only a longish spot below the cell remains free of it. Hindwings ochreous-yellow. In the $ the 
body is darker, the forewing is yellowish-white with brown veins; inner-marginal area dusted with a light brown, 
continued towards the middle of the border. New South Wales, Victoria. 
C. irrorata Rothsch. Antennae red-brown; head and thorax yellowish-grey, speckled with brown; irrorata. 
abdomen light grey, the 2 last rings yellow. Forewing yellow-reddish grey, speckled with brown; a postmedian, 
undulate, brown transverse line. Hindwing diaphanous yellowish-grey, in the distal half of the costal margin 
speckled brownish. The $ is larger and lighter. Length of forewings: $ 13 mm, $ 15 mm. Mount Goliath, 
Dutch New Guinea. 
C. warringtonella B.-Bak. Antennae brown, head orange; thorax brownish-grey, collar and base of warringio- 
shoulder-covers orange; abdomen grey with a yellow-reddish anal tuft. Forewing yellowish-white with a satiny 
lustre, the inner-marginal part below the median greyish-brown, towards the margin narrowed and terminating 
between the 1st median and 2nd radial; hindwing drab, proximal margin and fringes greyish-white. The $ is 
larger, the forewing white, the dark inner-marginal part narrower. Length of forewings: $ 15 mm, $ 21 mm. 
Stanley Mountains in British New Guinea. — subsp. goliathina Rothsch. is larger, forewings in the <$ of a deeper goliathina. 
yellow, in the $ cream-coloured. Length of forewings: $ 19 mm, $ 19^ mm. Mount Goliath, Dutch New 
Guinea. 
C. castanea Rothsch. Antennae brown; head and collar yellowish-brown; thorax chocolate-brown; castanea. 
abdomen clrab. Forewing chocolate-brown, clouded chestnut-brown and with a purple reflection; a stripe on 
the submedian fold to the proximal angle black, speckled white. Hindwings diaphanous grey. Length of 
forewings: 18 mm. Mount Goliath. 
C. reticulata Rothsch. is an uncommonly variable insect; in the typical form the head is reddish reticulata. 
yellowish-white, palpi black, antennae brown; thorax light yellowish-brown; abdomen Isabel-coloured with 
a yellow anal tuft. Forewings chestnut-brown, strewn with Isabel-colour, a broad, whitish diffuse spot, between 
the inner-marginal vein and median, from the base to % of the length; at the end of it is a dark brown spot. 
Hindwings Isabel-coloured. . The $ is larger and lighter. The dusting may be much more intense and cover 
more or less the light diffuse spots, whilst the whitish strewing may also increase very much, particularly in 
the §. The hindwings may turn somewhat salmon-coloured in the $. Length of forewings: $ 20 mm, $ 23 to 
25 mm. From Biagi and the Angabunga River in British New Guinea. 
119. Genus: Bitecta Heijl. 
Separated from the preceding by longer, straightly porrect palpi with a long slender terminal joint; 
the last abdominal ring and the valves are long-haired. The middle part of the costal margin of the forewing 
is long-haired beneath and turned over upwards, in the base of the cell there is a hairy spoc, the cell itself 
very narrow; the 1st median and 3rd radial are on a short footstalk, the 2nd radial is absent; the 1st rises 
near the lower cell-angle, the 5th subcostal vein from the upper one; the 3rd and 4th are petioled. On 
the hindwing the 1st median and 3rd radial are likewise petioled, the 2nd radial is absent ; the subcostal rises 
before the upper cell-angle. 
B. murina Heyl. (15 d) has greyish-brown forewings with darker-veins, the basal half of the costal murina. 
margin is light yellowish. Hindwing yellow with a light brown distal third. Borneo, Java.
