solid in texture and shows none of the underside markings 

 through. Catilina is also a larger and more robust species. 

 The specimens of aniinon before me measure 20-21 mm. 

 against 26 mm. in catilina. I have a good series from Arizona 

 and Florida in my collection which were sent me as a nun on, 

 but after comparing them with the Cuban insect and with tin- 

 series in the National collection here, T have no doubt that 

 they represent, caiilina.

I have already referred briefly to this species, the types of 

 which are in the British Museum, there being a fair series 

 there. 



It appears to me to be quite distinct from catilina, though 

 a close ally. It very probably replaces that insect in its own 

 regions. Its color is violet blue, almost exactly like hanno 

 above, but the underside is near to catilina, the differences 

 being that the transverse band in the primaries is much nearer 

 the termen, quite a different shape, being oblique, not more 

 or less curved, and being very irregular ; there is no white 

 space between it and the submarginal rows of markings which 

 it touches ; the same characters apply to the secondaries except 

 that there is a very slight white postmedian trace. There are 

 two anal black spots with metallic blue, the upper and larger 

 of which is edged internally with a red crescent. 



We still have to consider two other insects, Hcsperia Rural es 

 ceraunits Fabricius (Ent. Syst. Ill, p. 303, No. 149) and 

 Riisticns adolcscens Jianno Hiibner (Samml. Exot. Schm. I, 

 Plate 98, ff. 1-4). In Wytsman's reprint of the latter work, 

 Kirby (vol. Ill, p. 72) refers Hiibners hanno to ccraunus F. 

 and from Fabricius' careful description (1. c.), where he men- 

 tions the most important characters, I have no hesitation in 

 accepting Kirby's allocation. I am glad to be able to confirm 

 this from another source, and I have to thank M. Oberthiir 

 again for this opportunity. Among the specimens he was so 

 good as to send me are two, one from Boisduval's collection 

 and one from Guence's ; that from the former is labrlU-d in.
