LÉPIDOPTÉROLOGIE COMPARÉE 35 I 



with black spots. In Pœcilopsis and Lycia, two of thèse spots 

 on the anal plate, bearing bristles, are very large and so are four 

 similar ones on the postcrior edge in ail. 



Pupa. 



The pupae are large and stout for Gcomcirid pupas, and are 

 brown of various shades in colour. The whole surface is minutely, 

 though regularly, pitted. The usual pupal bristles are weak on 

 the thorax and abdomen, but become very strong on the head. 

 Viewed from above, the pupae are fairly regular in breadth until 

 the 4th abdominal segment is reached, after which they taper more 

 or less regularly to the two side spines which are found before the 

 terminal spine of the anal process which projects, like a spike, 

 after this and gives rise to two fmer spines. It is to be noted, 

 that segment 8 is broader and longer; in proportion, in Pœci- 

 lopsis and Lycia it bears two very obvious dorsal warts. Viewed 

 from the side, we hâve an abrupt upward curve to the metathorax 

 and a gentle curve down after that to the /th abdominal followed 

 even independently of the two warts by a rise in the 8th segment. 

 The fall after that to the ends of the anal spine is regular. The 

 spiracles are small but very distinct as is also the scar of the last 

 spiracle in Ithysia. The wings cases are rather small; those of 

 the legs cases are quite neat but the glazed eye is not prominent. 



Needless to say, the antennae cases are very broad and the 

 pectinations generally well shown even m the females. For the 

 most part the female pupse simply vary in their superior stoutness 

 and their erenital scars from those of the maies. 



Imago. 



The markings of the maies are those of the typical Geometer, 

 but, for the sake of convenience, it seems best to look upon the 

 first three dark bands of the forewings as the first, médian and 

 second respectively, but to regard the subterminal pale band,
