 dimidium abdomen superantia, valde longiores quam latae, apice late rotundatae, margine externo et

A genus containing extraordinary forms, resembling the slender Phasmidae, with 

 beautifully coloured wings and short elytra. The spines of the anterior femora are 

 rather long; on the inner edge the last spine is long, and it is separated from the 

 apical spine by an unarmed space. In the females the wings are semiorbicular ; in 

 the males they are longer, but very obtuse, and widely rounded at tip. 



The various species of Angela seem to be confined to the northern part of South 

 America and to the southern part of Central America. 



05s. Stal and Brunner de Wattenwyl have adopted the name Thespis, Serv., for this 

 genus ; but the name Angela having been used by Serville for a subdivision of his 

 genus Thespis, it must be retained, and Thespis applied to the T. sulcatifrons of 

 Serville (an African species). T. livida and T. infuscata belong to the group 

 Miopteriges. 



Synopsis specierum. 



a. Alae membranacese ; campo postieo fusco-violascente, venulis luteis, anterius fasciis splendide 

 f usco-violaceis venulisque destitutis ornato ; campo antico latiusculo, pallidiore, apice sub- 

 coriaceo. Cerci latissimi, foliacei, rugosi, truncati. (Marium elytra quam alae paulo 

 breviora ; alarum margo posticus parum arcuatus.) 

 b. Abdominis segmenta haud tuberculata. Pronotum posterius leviter incrassatum, margi- 

 nibus denticulatis. Elytra ? alis paulo breviora, area membranacea anali, basi excepta, 

 nigra. ? . Alse dense scalari-venulosae ; eorum fasciae inter maculas fuscas densissime 

 flavo-venulosse. 

 c. Alas fasciis fusco-violaceis $2, ^ 3, inter illas flavicantes. — [1. brachyptera, St.]
