II. On certain species of Pericopides in the Collection 

 of Mr. W. Wilson Saunders: ivith a List of the 

 described species pertaining to that Group. By 

 Arthur G. Butler, F.L.S., F.Z.S., &c. 



[Bead 1st Januaiy, 1872.] 



Mr. Saunders having kindly allowed me to describe the 

 new species of Pericopides in his Collection, I have taken 

 this opportunity of correcting one or two errors to which 

 Mr. Brown, his Curator, has called my attention. 



Upon comparing the types of P. hivittata in the British 

 Museum, and P. disjancta in the Collection of Mr. 

 Saunders, it was found that the two forms are specifically 

 identical, the differences between them being merely 

 individual in character. 



The genus Daritis is identical with Pericopis in struc- 

 ture, and I think it quite likely that D. marginalis may 

 prove to be the female of P. dissimulans . 



My P. lunifera (type in Coll. Saunders) is P. turhida, 

 of Hubner's Zutrilge; the latter was placed amongst the 

 varieties of the species in the National Collection, P. 

 Agldura and P. tricolora being considered as opposite 

 sexes of the typical form. 



The following are new species : — 



Genus Esthema. 

 Esthema confluens (Felder, in litt.) . 



Alas supra coeruleo-nigree ; anticee fascia postmediana 

 subhyalina alba, introrsum obliqua, extrorsum arcuata a 

 venis nigris interrupta ; posticas areis basali et interna 

 nitente virescentibus, fascia media lata, utrinque subito 

 angustata, subhyalina, alba, a venis nigris interrupta : 

 corpus nitide virescens, capite albo-punctato, antennis 

 nigro-fuscis. 



Alae subtus nigrescentes, area basali viridi-striata: 

 corpus griseum a latere virescens, thorace albo-punctato, 

 abdomine albido annulato.
