EXOTIC MICROLEPIDOPTERA. 
Type pyrometalla. I refer here also haematographa Hamps., 
argyrostrotci Hamps., and phoenicozona Hamps., placed by their 
author in Balaenifrons ; I have not seen them, but from the 
descriptions it is incredible that they should not be congeneric 'with 
pyrometalla. I have not seen the type-species of Balaenifrons 
either, but according to Hampson it has a cubital pecten in the 
hindwings, veins 7 and 8 connected by an oblique bar instead of 
anastomosing, eyes small rather than otherwise, maxillary palpi 
quite different, and wholly dissimilar superficial characters, and he 
refers it to the group which I term Oalleriaclce ; I infer that he was 
misled by the singularity of the frontal development to unite two 
groups which must at least form separate genera, overlooking their 
differences. Until further evidence is available, T must also regard 
them as belonging to different families. I conjecture that the 
curious frontal development has in each case been acquired in 
mimicry of Homoptera. 
Taurometopa pyrometalla, n. sp. 
B . 16 mm. Head dark red with some pale yellowish spots, 
collar edged whitish. Palpi dull reddish, towards base pale 
yellowish. Antennae pale yellow ringed dark red. Thorax dark 
brown-red, inner edge of tegulae and posterior edge of metathorax 
yellow-whitish. Abdomen brown-reddish suffused crimson on 
dorsum posteriorly, segmental margins white, ventral surface 
silvery-white. Fore wings somewhat elongate-triangular, costa 
gently arched, termen bowed, oblique ; light brassy-yellow ; anterior 
area mostly occupied by three irregular variously connected dark 
crimson fasciae suffused violet-metallic except on edges, third running 
from before middle of costa to beyond middle of dorsum ; a similar 
blotch on costa beyond middle, posterior angle prolonged downwards 
by a short striga ; two similar irregular partially confluent fasciae 
forming a terminal band narrowed downwards, leaving costal edge 
orange-yellow, two irregular transverse yellow spots on termen 
above and below middle, and three smaller spots between fasciae : 
cilia pale yellow, becoming orange-yellow round apex. Hindwings 
brassy-whitish-yellow, dorsal area suffused grey, extending into 
cell before transverse vein, costal area faintly greyish posteriorly, 
costal edge pearly whitish towards middle ; a small spot of dark 
crimson irroration below angle of cell ; a large quadrate dark grey 
apical blotch connected by a somewhat smaller deep crimson 
quadrate blotch irregularly marked violet-metallic suffusion, with 
a triangular suffused dark grey blotch below proflexus : cilia yellow- 
whitish, round apex grey.
