578 mr. a. g. butler on the genus catagramma. [dec. 13, 



Bacillus geisovii. 



Viridis ; capite carina obliqua inter oculos et basin antennarum ; 

 vertice et occipite 10 nigris spinis ; proth. yranulato ; meso- 

 et metathorace et segmentis abdom. spinosis ; pedibus spiinosis 

 et foliaceis. 



Mas. Long. corp. 18£"', ant. 4"', proth. 1"', mesoth. 3i'", metath. 

 4'", abd. lin. 10 + lin. l=lin. 11. 



Hab. New Zealand. 



The ten black spines of the head are placed in three rows. On 

 the end of the prothorax, in the middle, a black spot ; and a fine 

 line along the middle of the mesothorax. Some of the irregularly 

 formed and placed spines are black at the ends. The tubercles of 

 the metathorax obtuse and unicolor. The leaves look short ; anal 

 styles on both sides in the middle carinated. One of the middle 

 and one of the hind legs in the specimen described are shorter, and 

 have been reproduced. 



I have named this small and slender species in honour of the friend 

 of Mr. Gerhard Midler, Mr. Wilhelm Geisow. 



Besides these two species there is yet only discovered in New Zea- 

 land Bacillus hookeri, White, which has no spines on its body. 



10. Note on some Species of Butterflies belonging to the 

 Genus Catagramma. By A. G. Butler, F.Z.S., As- 

 sistant, Zoological Department, British [Museum. 



In consequence of the similarity of many of the species of Cata- 

 gramma, several errors have occurred in their synonymy ; forms 

 which could, with proper care, be readily distinguished from each 

 other have been kept together as representatives of one species. 



In Mr. Doubleday's "Genera of Diurnal Lepidoptera,' p. 239. n. 2, 

 I find Papilio chjmena of Cramer, Papilio clymenus of Fabricius, and 

 Callicore clymena of Hiibner placed together as synonymous ; but 

 after having carefully compared all the figures with the Banksian 

 types and with the specimens in our collection, I find that C. 

 clymena of Cramer is quite distinct from Fabricius's type, that 

 .the latter is identical with C. janeira of Felder, and intermediate 

 between C. anna and C. marchalii of Guerin ; and that the species 

 figured by Hiibner in his ' Zutrage ' is identical with C. eluina of 

 Hewitson. 



The synonymy of these three species will therefore be as follows : — 



1. Catagramma clymena.
