PSYCHE. 



[February 1S94. 



Periplusia. gen. nov. 



Allied to the preceding genus. Palpi short, 

 porrect, ascending; antennae simple. Costa 

 of primaries straight, or very slightly curved. 

 Apex acute. Outer margin evenly rounded, 

 as also the inner margin. The outer angle 

 very obtuse, rounded. The secondaries are 

 suboval, with the outer and inner margins 

 evenly rounded. The extremity of the ab- 

 domen does not project beyond the outer 

 margin of the secondaries. The neuration 

 is depicted in the accompanying cut. Type 

 P. /iiihilicosta Holland. 



Neuration of P. nuhilicosta, Holl., ^ , 'j. 



15. P. inibilicos/a, sp. nov. $. Palpi 

 pale ochraceous; front whitish; collar dark 

 brown, edged with pale cinereous. Upper 

 and under side of thorax and abdomen pale 

 gr.iy. Legs gray with the anterior margin 

 of the tibiae of the first pair marked with 

 dark brown. The primaries on the upper 

 side are pale gray marked just below the 

 costal margin, which is lilacine-gray, with a 

 broad diffuse dark brown, or blackish ray 

 running from the base to beyond the cell, 

 and then sweeping upwardly to the apex. 

 The secondaries on the upper side are uni- 

 formly fuscous. On the under side the 

 wings are marked as on the upper side, but 



all the markings are paler and more diffuse. 

 Expanse, 32 mm. 



16. P. cinerascens, sp. nov. $ . Body and 

 appendages much as in the preceding species, 

 save that the collar instead of being brown, 

 as in that species, is uniformly dark gray. 

 The primaries on the upper side are obscure 

 cinereous, in fresh specimens suffused with 

 a light plumbeous tint. There is an obscure 

 minute whitish dot at the end of the cell and 

 the wings are crossed by irregular obscure 

 dark transverse sub-basal, median, limbal, 

 and submarginal lines. The upper side of 

 the secondaries is uniformly fuscous. The 

 under side of primaries is fuscous with the 

 apical extremity of the costa, the inner mar- 

 gin, and a linear mark at the end of the cell 

 whitisli. The under side of the secondaries 

 is pale fuscous with the outer margins darker. 

 There is a pale spot at the end of the cell, 

 and beyond it running from the middle of 

 the costa an incomplete transverse median 

 dark line. 



9 . The female is like the male, but with 

 a more robust abdomen, and sornewhat 

 darker. Expanse, J . 30 to 33 mm.; $, 33 

 mm. Habitat. Kangwe and Benita. 



17. P. eccltpsis^s.'p. nov. $. Palpi whitish. 

 Upper side of thorax and abdomen pale gray; 

 lower side of thorax, abdomen, and legs 

 whitish. Primaries on the upper side gray, 

 slightly paler on the outer margin, with a very 

 large dark brown, semi-lunate spot on the 

 costa from its middle to just before the apex. 

 The lower edge of this spot touches the second 

 median nervule. It is cut at its outer extrem- 

 ity just before the apex by a very narrow pale 

 line. There is a very narrow marginal line 

 of brown and a small brown dot near the outer 

 angle. The secondaries are fuscous on the 

 upper side. On the under side both wings are 

 pale fuscous and both have a very obscure and 

 incomplete transverse limbal line. Expanse, 

 25 mm.
