CYDIMONIN^;. 43 



Sir G. Hampson, in his work on the Moths of India, has lately 

 extended the Family Uraniidce (here called Cydimonidce) so as 

 to include a number of large and small white Moths belonging 

 to the genera Urapteroides, Moore ; Strophidia, Hiibner ; Mi- 

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

 as Geometrce. Many of these have a short lobe or tail at the ex- 

 tremity of the upper median nervule of the hind-wings, and 

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

 includes in the same Family the genus Chatamla, Moore, a 

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

 a superficial resemblance to the genus Euschema, Hiibner, in 

 the Geometry 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. 



Pupa, 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. Antennae pointed, more or less thickened before 

 the tips. Wings ample, with no internal nervures, but sometimes 

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

 nervule. This Family includes two genera of brightly coloured 

 tailed Moths, which were originally placed with the Equites. 

 Later authors regarded them as allied to the Hesperiidce, but
