These specimens have a light spot on the primaries; and the 

 secondaries are more elongated than in P. leodamas, Wall., the 

 species we should have expected to find here. They do not differ 

 from the ordinary type of P. polydorus. 



4. Description of a new Species of the Orthopterous Genus 

 Phylloptera from Madagascar. By Arthur G. Butler, 

 F.L.S., F.Z.S., &c. 



[Eeceived May 23, 1878.] 



The genus Phylloptera is one of the numerous interesting groups 

 amongst the Oithoptera which exhibit a striking resemblance to 

 leaves, some of them being imitated in a green condition, and others 

 when faded. 



The species now before me is an admirable example of this 

 adaptation to surrounding conditions, the tegmina being quite like 

 sear and yellow leaves in which the brown patches of decay have 

 begun to appear. 



Phylloptera segonoides, n. sp. 



Tegmina of the normal elliptical form ; horn yellow, with the 

 veins and borders more or less tinted with burnt sienna ; the whole 

 of the areoles, excepting those along the anterior border, with central 

 irregular dull greyish-brown spots or patches ; under surface paler, 

 with greenish borders ; wings hyaline-white, veins yellowish, the 

 normal black-dotted horn-yellow cuneiform patch bounded by an 

 oblique brown line at the very acuminate apex ; frons testaceous ; 

 eyes (in the dead example) chocolate-brown ; antennse black, with 

 testaceous scape ; back of head sordid whitish, with two divergent 

 grey lines from behind the antennse ; pronotum black, whitish in 

 front, with the sides, posterior third, and a V-shaped central
