UNDER the foregoing general title, it is proposed to issue a 

 series of Monographs of the genera of Lepidoptera and 

 other important Entomological groups, founded on the principal 

 public and private collections, British and Foreign. Each Mono- 

 graph will be a complete and independent work, while forming 

 one of a series which, it is hoped, may ultimately include all 

 the more important Entomological groups. The genus Teracohis, 

 b)' Miss E. M. BowDLER Sharpe, the first of the series, is uow 

 in course of publication. 



In the present Monograph will be figured all the more 

 important forms of the Memhracidcc known up to the present 

 time with anatomical details. 



The family of the Memhracida: has claims on the notice 

 of both the scientific and general public. Owing to the advance 

 of agriculture, climatic variation and other influences, organic 

 forms are constantly undergoing transformation, while some may 

 even become extinct. The present time, therefore, affords oppor- 

 tunities for studying and recording these forms, which may not 

 occur again. 



The general public will find interest in the bizarre forms 

 of these insects, while the speculations of the scientific mind 

 will be exercised on the question of their utility. 



The Memhracidce are also interesting from their mimetic forms 

 which will be considered in this Monograph. 



By the kindness of numerous friends, opportunities of drawing 

 from the best collections of this and foreign countries have been 

 afforded to the Author. 



The work, medium 4to in size, will be issued to Subscribers 

 for the complete Monograph only, in Five Quarterly Parts, each 

 with Ten Coloured Plates, 21/- net. 



Subscriptions for the Five Parts if paid in advance, 

 £4 14s. 6d. delivered post free.
