Description of a neio species of Blattaria : by A. G. Butler. 



In a small collection recently obtained from Eock- 

 hampton, I found two Blattaria^ new to the cabinet of the 

 British Museum ; the first of these proves to be Polyzosteria 

 hicolor of Saussure, the second is apparently a new species 

 of Ellipsidion allied to E. reticulatum and E. australe. 



Ellipsidion gracile, n. sp. 



Ovato-pyriforme ; capite nigro, vertice luteo ; antennis 

 — ? palpis luteis ; pronoto elliptico, margine postico sub- 

 angulato, luteo, nigro bimaculato ; meso et metanotis 

 nigris, marginibus posticis anguste luteis ; abdominis seg- 

 mentis supra nigris, cercis supra luteis ; elytris fulvis, luteo 

 reticulatis, ad basin et apicem anguste nigris ; alis luteis 

 ad apicem anguste nigris ; corpus subtus nigrum, abdominis 

 segmentis 1 — 6 albido lateraliter marginatis, segmentis 1 — 5 

 postice albido marginatis ; coxis postice luteo marginatis ; 

 femoribus nigris, tibiis spinosis fulvis ; tarsis nigris. 

 Long. 0,015; cum elytris 0,018. 



Eockhampton. 



Differs from E. reticulatum in its larger and more grace- 

 ful form, the narrower black apex to the elytra, and the 

 colour of the legs.
