Messrs. Houlbert and Oberthiir make the statement in common with many 

 other aiithors that godarti of Menetries is the same as strigata of Walker. This 

 is the more astounding because they have separated as good and distinct species 

 many much closer allied forms, such as licus, licoides, and licoidella. Anyone 

 comparing Menetries' figure with that of Butler of the type of Walker's strigata 

 will perceive at once great differences ; in the drawing of Menetries the median 

 longitudinal band is almost parallel to the streak in the cell and quite straight, 

 while in Butler's plate it is almost S shape ; then in godarti there are a series of 

 4 white patches above vein 1 , whereas in strigata there are only 2 ; on the hind- 

 wings the median band in strigata consists of small linear or irregular white 

 spots, whereas in godarti these spots are large quadrate patches. In fact, except 

 for the presence of the white streak in the cell and the slight break between the 

 longitudinal and the oblique transverse white bands on the forewing, Butler's 

 figure agrees almost exactly with Strand's decussata fulvipyga. It is true that 

 the figure of godarti appears to be that of a ?, while that of strigata is of a 3, but 

 in decussata, the nearest allied species, the sexes only differ in the size of the 

 white markings, not in their number or shape. 



There are no specimens of this form at Tring.] 



Castnia (Ypanema) godarti Menetries 



Castnia godarti Menetries, Descr. Nouv. Esp. Lepid. Mus. Petr. part iii. p. 130. no. 1462. pi. xi. fig 

 4 (1863) (Diaraantina, Brazil). 



Of this form there are two specimens at Tring agreeing in all respects with 

 Menetries' figure except that the white longitudinal band on forewing below 

 median vein reaches base of wing. As these are both (J<J it more than proves 

 my contention that godarti is not the ? of strigata.

Of this species the Tring Museum possesses 23 specimens, one of which 

 has the ground-colour metallic plum purple instead of metallic oil green ; I 

 propose to call this ab. pupnrascens ab. nov.
