HYMENITIS. By B. Haensch. 163 



are coincident to the end of the cell; only one hair-pencil is present, the upper radial is absent. The dark 

 spots at the end of the cell on both wings are smaller. The white ruarginal dots of the hindwing are trian- 

 gular. -^ zalmunna Hew., from Ecuador and Peru, is another similar form with narrower margins, narrower zalmunna.

 is distinctive. The costal margin of the forewing is not yellow-brown. Both wings have yellow tone. The 

 pattern is somewhat different from that of theudelinda. The distal margin of the forewing is more broadly 

 margined with black between the teeth. The white marginal dots of the hindwing are smaller. The spots 

 at the end of the cell on both ^nings narrower, band-like.

 margins. 



A similar, somewhat smaller species, which 1 call D. lauta spec, nov., differs especially in the ab- lauta. 

 sence of the band-spot in the cell of the forewing. It is very similar to Hymenitis umbrosa, from which 

 it may be distinguished both by the size and the different neuration. In the $ the two white dots of umhrosa 

 at the apex of the hindwing beneath are wanting.

 spot at the end of the cell of the forewing. — panthyale Fidr., from Colombia, is similar to the preceding, panthyale.

D. hewitsoni Hsch. (41 e), from eastern Ecuador, has transparent wings with yellow-brown sheen, hewitsoni. 

 with fine, darker margins and no other markings. Subcostal and inner margin of the forewing are light brown. 



34. Genus: Hymenitis Hbn. 



In this genus the lower discocellular of the (J i'S not angled and is undeveloped towards the costal 

 margin, hence the ceU open. The principal difference from Disme7ntis is seen in the $$. In these the 

 upper radial of the hindwing is coincident ■wdth the subcostal to one-half, in Hymenitis it is coincident with 

 the lower radial half-way. Hence the middle discocellular is absent here. 



To Hymenitis belong mostly medium-sized, plain-looking forms, which resemble certain species of 

 Leucothyris and Pteronymia, but may be recognised by the non-angled, slightly curved lower discocellular, 

 which closes the cell almost alone. Some larger species recall forms of Velamysta and Disnienitis 

 in the pattern and colouring. This genus is rather rich in species, of which the south-west of South America 

 produces the largest number, but Central America and Mexico have also some characteristic forms. 



H. albinotata Btlr. (41 g), from Colombia, recalls Velamysta crucifera (40 f) and torquatilla (40 f) by albinoiaia. 

 the dark markings of the hindwing; the forewing is similar to that of Dismenitis gonussa (41 c, d). The 

 colour is yellowish, at the base of both wings red-brown. Particularly striking are the two white dots in 

 the apex of the forewing. — kedema Hew., from Venezuela, is a similar, smaller form with weaker, pale kedema. 

 colouring and indistinct band-marking at the distal margin of the hindwing. — furina Godm. & Salv. is a form furino. 

 of albinotata from Panama with dark base to the cell of the forewing, lighter base to the hindwing and weaker 

 black markings at the distal margin of the hindwing. 



H. andromica Heiv. (41 f), from Venezuela, Colombia and western Ecuador, and its subspecies are andromica. 

 some of the commonest and most widely distributed local forms. In typical andromica the colourless ^vings 

 have a shght smoke-brown tinge and black-brown margins and patches. Beside the pointed half-band of 

 the forewing runs a broad, undulate white oblique band from the costal to the distal margin. In the apex 

 are placed 2 whitish vitreous sj^ots, which in the $ are completely enclosed by the broad black apex. — As 

 drotnica Staudixg-ee (i. I.) designated a smaller form from Colombia with narrow margins, weak half-band dromica. 

 and naiTOW white oblique band at the end of the cell of the forewing. — andania Hpffr. (= Ij^rina Stgr. andania. 

 i. I.) is a form from eastern Ecuador, Peru and Bolivia with vitreous, black-margined wings and interrupted 

 white obhque band on the forewing. The apex of the forewing is more narrowly black and in the $ the 

 hyaline spots are not proximally bordered with black. — lyra Salv. is the form from Central America (Guate- lyra. 

 mala, Costa Kica). It is distinguished from andania by having the half-band of uniform breadth and not 

 pointed, and a narrower white macular oblique band on the forewing. The black tooth bordering the sub- 

 apical hyaline spots at the costal margin is absent. 



H. nero Hew. (41 e), from Central America, Costa Pdca to Mexico, is similar to the preceding, larger, nero. 

 with broader margins and patches. The subcostal of the forewing and the distal margins are partly red- 

 brown. On the underside of the forewing the 2 white apical dots of lyra are absent.
