CYDTMONIN.^. 43 



Sir G. Ilampson, in his work on tlie Moths of India, has lately 

 extended the Family Uraniidcc (here called Cydi)iionid(e) so as 

 to include a number of large and small white Moths belonging 

 to the genera L/rapferoides, Moore; StropJiidia^ Hiibner; Mi- 

 cronia, Guenee, &:c., most of which have hitherto been regarded 

 as Geo/nefnr. Many of these have a short lobe or tail at the ex- 

 tremity of the up[)cr median nervule of the hind-uings, and 

 at the base of the tail are several black spots. He likewise 

 includes in the same Family the genus C/iafa//i/a, Moore, a 

 black Moth, with large white and yellow markings, which has 

 a superficial resemblance to the genus Eiischei)ia^ Hiibner, in 

 the Geometrce^ and several other genera, of duller colours, 

 which have long wing cells and rounded hind-wings, frequently 

 provided with two sub-median nervures of nearly equal length. 

 How far this extension of the Family is tenable will be tested 

 when we are better acquainted with the transformations of 

 these Moths. 



SUB-FAMILY I. CYDIMONIN^.. 

 Egg. — More or less spheroidal, ribbed, smooth at the summit 



Larva. — Sixteen-legged, cylindrical, with scattered hairs or 

 short bristles, gregarious, sometimes feeding under a web ; 

 head small. 



Papa. — Enclosed in a slight cocoon, or attached by a few 

 threads round the body. 



Imago. — Diurnal, of large size and brilliant colours; the hind- 

 wings tailed. Antennne pointed, more or less thickened before 

 the tips. Wings ample, w ilh no internal nervures, but sometimes 

 with pre-costal cells ; cells of both wings closed by an imperfect 

 nervule. 'I'his Family includes two genera of brightly coloured 

 tailed Moths, which were originally placed with the E(/uifes. 

 Later authors regarded them as allied to the I/cspcriidic, but
