Mr. W. F. Kirby on a new Dragonfly. 227 



j^gosoma Buckleyi, sp. n. 



Nigro-fuscum ; capite supra granuloso-punctato ; prothorace utrin- 

 que trispinoso, spina antica minima, dorso dense punctato, breviter 

 sparseque villoso ; elytris piceo-brunneis dense interrupteque 

 rugulosis utrisque lineis duabus elevatis sat distinctis, instructis ; 

 antennis {S) quam corpore paullo longioribus, articulis l°-3'" 

 asperatis, opacis, ( $ ) quam corpore brevioribus, articulis l°-3" 

 vix asperatis. 



Long, c? 40, 5 45 mm. 



ITab. North India [Colonel Buckley). 



This species seems most nearly allied to j^gosoma tihiale, 

 White, from which it may be easily distinguished by its 

 interruptedly rugulose (or granulated) elytra. It also bears 

 some affinity to ^. cingalense. White ; but in the latter there 

 is no anterior tooth on the side of the prothorax, the disk of 

 the prothorax has a depression in the middle, and the elytra 

 of the male are closely covered with a tawny pubescence. In 

 examples which I believe to be the females of JEgosoma 

 cingalense the elytra are naked and finely granulate ; and they 

 were such forms that Bates characterized as a distinct species 

 under the name of ^gosoma angustatiun. 



XXXII. — Description of a new Species of Dragonfly (Dy- 

 themis Broadwayi) from Trinidad. By W. F. KiRBY, 

 F.L.S., F.E.S., Assistant in Zoological Department, British 

 Museum (Natural History), South Kensington. 



The present species was sent over by Mr. Broadway, of the 

 Botanic Gardens, Trinidad, some time ago, but has remained 

 uudescribed till now, as I have not been working at South- 

 American dragonflies till lately.
