 Larva et Imago. 



basal joint reniform, the next cylindric, slightly attenuated at the apex, 

 the terminal more slender, bending outwards, and somewhat acute : 

 maxUla: long. Antennce elongate, setaceous, slightly pectinated to the 

 apex in the males : head clothed with loose scales : thorax stout, a 

 little crested behind, loosely squamous : body cylindric, rather long, 

 slightly carinated on the back, tufted at the apex : ivings horizontal, 

 entire, anterior elongate-triangular, with three stigmata : posterior 

 suborbiculate-triangular, usually pale yellow, with a darker hinder 

 border." — Steph. I/lust. Brit. Ent. Haust. II. p. 106. 

 Stephens considers this species as more allied in its habits to the Tri- 

 phcenae than the Poliae, from the latter of which it is readily known by its 

 proportionately shorter and broader (anterior) wings, and by the lively co- 

 lour of the posterior ; and from the former it differs in the proportion 

 of the joints of its palpi, its subcrested thorax, and dissimilar antennse. 

 Stephens mentions no other species as belonging to this genus.
