 Long. Corp. lin. 9. 



Habitat in China. Ex Mus. 0"= Crane. 



Corpus glaberrimum, luteo-virens, colore sub luce mutabili, 

 subtus cupreo tinctum. Caput supra antice punctis con- 

 fluentibus rugulosum, postice punctis sparsis conspersum, 

 interque puncta creberrima minutissima, vix sine lente 

 forti conspicua, subtus fulvum. Antennce fulvee. Thorax 

 punctis sparsis punctulis minutissimis interjacentibus ut in 

 capite. Elytra subrugosa, puncto-striata : striis interme- 

 diis per paria ordinatis, interstitiis punctatis et punctulatis- 

 simis ut in thorace, &c., apice gibba.

 of the former, with some diagnostics of the latter, it seems not 

 improperly introduced. 



Agrion Brightwelli. 

 Nigrum : alis basi, in altero sexu apice macula, sanguineis.
