iia -j- "b and iv -f- v on thorax, iv and v closely approximated and superposed on 

 abdomen. 



Pupa. Chocolate brown, abdomen somewhat lighter, cremaster eight stout, 

 dark brown hooks; length, II. 5 mm. 



Geshna primordialis, new species. 



Wings pale yellowish, more or less largely, often largely overspread with dark 

 brown ; lines dark brown, the inner slightly flexuous ; discal ringlet subreniform ; 

 outer line straight to end of cell, strongly excurved to near margin above tornus, 

 retreating below discal ringlet and reaching inner margin at middle. The brown 

 shading fills up nearly all the space between the marks, but leaves a light edge within 

 the inner line, beyond the outer, and before the discal ringlet. Hind wing with the 

 base to inner line brown; a light space in which are three irregular discal spots partly 

 or wholly fused to the outer line by dark shading ; terminal area broadly dark ; fringe 

 interlined with pale. Expanse, 12 to 15 mm. 



This species is common in the Northern Atlantic states, and I can 

 only account for my failure to find any previous description of it, by 

 its great similarity to Blepharomastix stenialis Guen., which may have 

 caused it to be overlooked. It differs superficially from that species 

 only in being smaller, although it is usually much darker shaded.
