PIITSOCEPHALA. 36'd 



280. Physocepliala atricornis, sp. nov. 



c? . Very inuch like P. adojnis. Big. Jt differs by lia\iiig the 

 2nd and 3rd aiitennal joints wholly black, wliile the 3nl is rather 

 dark brown ; occiput with a broad transverse black stripe ; nieta- 

 notuni rather light brown, dusted with pale golden-yellow; 

 abdominal segments not bordered with orange, but with a little 

 pale yellow dust, the last segment being wholly dusted with pale 

 golden-yellow ; and the tarsi brown, not black. The black band 

 on the wing does not even encroach on the 1st basal cell, much 

 less on the discal, and the wing is wholly dark from the costa to 

 the posterior limit of the band, /. e. the IJrd longitudinal vein. 

 The dark colour also fills the basal half of the 1st posterior cell : 

 moreover, it extends along the costa to beyond the tip of the 2nd 

 vein, but is thence rather shar|)ly delimited. This difference in 

 the longitudinal extent of the baud is perhaps the best specific 

 character.

 dark l)ro\vn. All the legs are microscopically pubescent. Wim/s 

 almost clear; a blackish colour extends along the costa from the 

 base as far as just beyond the tip of the 2nd longitudinal vein ; 

 this colour reaches posteriorly as far as the 3rd longitudinal vein, 

 where it sharply terminates, but is continued into the basal half
