that, those species which occui-ml in separate localities were distinct all the same. 

 Now, however, my ideas have been entirely changed by receiving from Aroa, 

 Venezuela, all the. named forms, and most of the intermediate forms, so that the 

 entire genus wants revision ; and I find tiiat out of fifteen six'cies enumerated by 

 Mr. Kirby only five can stand as good species, so that the synonymy is as follows : — 



1. Bilophonota ello (Linn.). 



2. D. picta (Sej>p.). 



3. 1>. laxsauxii (Boisd.). 



aberr. 1. merianae (Grote). 



4. D. obsciira (Fabr.). 



aberr. 1. oenotrax (Stoll). 

 aberr. 'Z. pemieiis (Fabr.). 

 aberr. 3. mclnncholica (Grote). 

 aberr. 4. omphaleae (Boisd.). 

 aberr. 5. rhaebus (Boisd.). 

 aberr. 6. janiphae (Boisd.). 

 aberr. 7. domingonis Butl. 

 aberr. 8. festa H. Edw. 



5. 1>. gutturalis (Walk.). 



aberr. 1. pallida (Grote). 



MANDUGINAE. 



MANDUCA. 

 Here both M. tsti/x (Westw.), and M. medimi (Butl.) occur in West China, 

 and intermediate forms, so that M. medusa (Butl.) must sink into a synonym of 

 M. sti/x (Westw.). 



SMERINTHINAE. 



METAMIMA8. 

 In this genus J/, banksiar (Boisd.) is only a colour alierration of the female of 

 .1/. itiistndaside (Don.) ; and M. amboinicus (Feld.), is not a Metanimas at all, but 

 ii tru<' Mdniinbii . 



CLANIS AND BASIANA. 



The genera Clams and Ba.siana have been confused and misajiplied so often 

 that it is not surprising that Mr. Kirby, with all his multifarious duties and 

 occupations, should, in trying to straighten out the tangle, have fallen into a fresh 

 error. 



Mr. Kirby also unites C. nicobarensis (Schwarz) to G. pJialaris (Cram.). This 

 is quite wrong, for it is much nearer to G. hilineata (Walk.) ; and the latter, if they 

 are united, would sink as a sjnonym of C. nkoharensis ; i)ut as my male and female 

 from the Nicobar Islands differ somewhat in size, colour, an<l marking from typical 

 C. bilineata, I prefer to regard G. nicohare.nsis as a distinct species for the present. 

 As Mr. Kirby correctly states, Glanis was founded by Hiibner on Sphinx phalaris 

 Cram., but Basiamt dencalinn Walk., on which Walker founded the genus 

 Basiana, is evidently of tlie same genus. Now tlie African sj)ecies of Basiana are 

 very diflereut, and much nearer to Pseiulosmerinthus ; so the way to clear up the 

 confusion, to my mind, is to unite all the Indo-Malayau species under the head of 

 Glanis, and to put the African species into a new genus, Pseiidoclauis.
