CATOPS1LIA.

Pupa. "Much stouter (i.e. than that of T.hecabe), and the 

 keel formed by the wing-cases much less pronounced. The normal 

 colour is pale green with a yellow lateral line. We have never 

 found it on any plant except Cassia occidentalis. It habitually 

 rests on the upperside along the midrib, like almost all Pierine 

 larvae." (Davidson <$f Aitlcen.)

$ . Closely resembles some $ specimens of C. pyranthe that 

 have the black markings on the fore wing reduced and narrow. 

 The $ however, shows a greater difference. 



The late Mr. de Niceville considered the two forms identical, 

 but whether this is so or not can only be tested by careful 

 breeding-experiments. After examining a long series of speci- 

 mens from Africa, India, and the Malayan Subregion, none of 



which can be referred to 

 either C. crocale or C. 

 scylla, the only two other 

 forms that occur within 

 our limits, I find I am 

 able to separate them, into 

 two groups : the speci- 

 mens in one group agree 

 absolutely with the 

 type of C. florella in the 

 Banksian Collection in 

 the British Museum; the 

 others differ. The two, 

 if there are two distinct 

 forms, cannot be consi- 

 dered geographical races, 

 as in many localities their range is conterminous, nor are they 

 seasonal varieties one of the other, for they have been repeatedly 

 taken together on the same day at the same spot. Of course 

 it is quite possible that C. florella is a dimorph of C. pyranthe, 

 but clear evidence of this is lacking. The chief points of 

 difference between the two forms are given in parallel columns 

 below :
