266 Mr. A. G. Butler on the Genus Fronophila, 



examining a flo^yer in which one of these organs, which are very 

 caducous, had fallen away; and this seems clearly proved by 

 the following circumstances. Schlectendal states that Hohen- 

 hacker's plant, on which he founded his genus, came from 

 the province of Cauara, on the south-vvestei-n coast of the Indian 

 peninsula. Now in the Hookerian herbarium I found a plant 

 of Hohenhacker^s from ]\langalore, in Canara, which I carefully 

 examined and ascertained that its flowers are hexamerous, 

 agreeing in every character with other specimens of DipJoclisia 

 indyta : it is also a ? plant, according with Schlectendal's de- 

 scription not only in the size and form of the leaves, but in the 

 length of the inflorescence, the distance and length of its pri- 

 mary branches, its almost umbellate branchlets, the markings 

 of the sepals, and the shape of the petals and sterile stamens. 

 It appears to me that there is not the slightest doubt of their 

 absolute identity; and I therefore think that the genus should 

 be suppressed, and that Quinio cocculus, Schl., should stand as 

 a synonym of Diploclisia inclyta. 



XXXIII. — Revision of the Grovp of Lepidopterous Insects 

 hitherto Included in the Genus Fronophila of Westwood. By 

 A. G. Butler, F.Z.S. 



I HAVE recently had occasion to rearrange the species of butter- 

 flies included in Pronophila ; and, being struck with their great 

 variety of form and difi'erent style of colouring, I have made a 

 careful examination of all their structural details : the result of 

 my investigations has been to reveal great differences of form in 

 the cell of the front wings, and of position with regard to the 

 emission of the subcostal and discoidal nerves ; the palpi also 

 differ slightly in form, length, and position. 



The type of the genus Pi-onophila is P. Thelebe of Westwood 

 and Hewitson. This group, represented by only five species, 

 one of which is as yet undescribed, may now stand as fol- 

 lows : — 



Genus 1. Fronophila, Westwood (part.), 1851. 

 Typical Species, Pronophila Thelebe. 



Gen. Alis inagnis, repandis : anticis subintegris, margine externo 

 paulum undato : posticis margine undulato. 



Alis anticis ceUa obtuse bifurcata, furca inferiore subquadrata, 

 lougiore ; furca superiore conica, venas secundam et tertiam subcos- 

 tales et primam discoidalem ferente ; veuis his omnibus ad origines 

 confertim approximantibus. 



Caput palpis mediocribus prseporrectis.
