 Stephens mentions only one species of Euplexia. 

 Tkachea, Ochs. (Genus 59.) 



" Palpi moderate, the basal joint pubescent, the second densely clothed 

 with scales, the terminal minute, exposed, ovate ; basal joint stouter 

 and shorter than the second, a little bent; second stoutest at the 

 base, rather attenuated at the apex ; terminal one-third as long as 

 the second, rather slender, ovate; inaxillce elongate. Anleymce f\m\>\e 

 in both sexes, pubescent beneath and ciliated in the males : head with 

 a dense frontal crest, produced into a tuft at the base of each antennjE : 

 eyes globose, naked : thorax stout, quadrate, crested anteriorly and 

 posteriorly : abdomen elongate, carinated and crested on the back in 

 both sexes ; male with a small anal tuft: wings deflexed during repose, 

 anterior elongate-triangular, the posterior margin faintly denticulated ; 

 posterior ovate-triangular. Caterpillar naked, smooth : pupa subter- 

 ranean." — Steph. I. c. p. 21. 

 The only species which Stephens enumerates as of this genus is Noct. alri- 



jilicis, Linn., the first in Treitschke's catalogue, and constituting hisFamily A. 



— For Treitschke's three remaining species, viz. Prcecox, of his Fam. B., 



and Porphyrca, and Viniperda, Fam. C, Stephens has adopted as many 



distinct genera, Actebia, Scotophila, and Achatia, with the following 



characters assigned them respectively. 

 Actebia ^, Stephens. 



" Palpi short, robust, porrected obliquely, densely clothed with com- 

 pact scales; the terminal joint exposed, subrhombic ; the two ba- 

 sal joints nearly of equal length and stoutness, the first curved, the 

 second shuttle-shaped, the terminal slender, elongate-ovate : maxilla: 

 elongate. Antennce elongate, slender, pubescent beneath, ciliated on 

 each side in the males ; the basal joint large [and squamose : head 

 small, with a dense frontal crest : eyes large, globose, naked : thorax 

 slightly crested posteriorly : abdomen elongate, somewhat depressed, a 

 little pubescent at the base, slightly carinated in the males, with a 

 small anal tuft; stouter in the females : 7wwg5 deflexed during repose ; 

 anterior very narrow, linear, entire, glossy ; posterior ovate-triangular, 

 entire. Caterpillar naked, smooth : pupa subterranean." — Ste2}h. I. c. 

 p. 20. 

 Only one species. 

 •Scotophila'', Stephens. 



" Palpi rather distant, porrected obliquely, slender at the base, subclavatc, 

 the two basal joints clothed with rather elongate scales, the apical mi- 

 nute, exposed, somewhat acute; the basal joint about two-thirds the
