 the same scale.

In general appearance, most closely resembling media, but 

 larger and usually with more fuscous ; certain color phases of 

 the female sometimes difficult to distinguish from the females 

 of media.

$ . Length 6.7 mm., width, 2.14 mm. Dark red, having more fuscous 

 on the pronotum and scutellum than in media; larger and more elon-
