PANjETHIA. 239 



FAMILY ZERENID^E. 



This is a family of rather large or moderate-sized moths, 

 with broad wings, and slender downy bodies ; and usually spotted 

 with black on both wings and abdomen. The antennae are 

 simple or pectinated, the palpi short, and the proboscis well 

 developed. The legs are short, and the hind tibiae often 

 swollen. The larvae are short and stout, and feed on trees 

 and shrubs ; the pupae are short and obtuse. 



This is one of the prettiest and best-known families of the 

 Geometra.

PAN^ETHIA MACULOSA. 

 (Plate C XL VIII., Fig. 4.) 

 Arycanda maculosa^ Walker (MS.). 



This Moth, which inhabits Sumatra, measures about two 

 inches and a half across the wings. The insect varies from 

 bluish-grey to dull blue, with numerous black spots and mark- 

 ings on the thorax and wings. The fore-wings have a large 

 spot at the base, five transverse bands, more or less broken up 

 into spots, and a row of oblong longitudinal spots on the hind 

 margin. The hind-wings have four macular bands, the third 

 occupying less than the upper half of the wing ; and 

 sub-marginal oval spots, as in the fore-wings. The abdomen is 

 yellow, with the base grey.
