We have examined the types of Achlyodes ophia, Butler, Pterygospidea sephara r 

 Hewitson, and Pythonides cobarus, Moschler, and have also before us a specimen named 

 by Semper Udranomia ambla from Plotz's drawings, and can find no specific difference 

 between them. Having also a good series of specimens from the Mexican State of 

 Vera Cruz, whence R. Felder's Leucochitonea lugubris was derived, the description of 

 which agrees closely with the present insect, we have no hesitation in adopting the 

 latter specific name for it. Pythonides lugubris, as we propose to call this species, 

 affords a good illustration of the confused state of the nomenclature of the Hesperiida?, 

 as it has received five specific names at the hands of various authors, and been referred 

 to as many genera by them ! 



It is a fairly abundant species in Eastern Mexico, and thence southwards throughout 

 Central America, and has also a wide range on the southern continent. Its nearest 

 relative is Pythonides truncata (Hew.), from Bolivia ; but it may readily be distinguished 

 by the less angular secondaries and the absence of the blue-grey colour of the same 

 wings beneath. 



The male genitalia are simple ; the tegumen is rather elongated and slightly depressed ; 

 the scaphium well developed and long; the harpes are symmetrical, rather long, and 

 upturned, with a truncate end and a deep fissure on the dorsal edge. (See Tab. LXXXII. 

 fig. 13.)
