downwards. The secondaries are shortly lobed at the anal angle, reaching about as 

 far as the apex of the abdomen ; the discocellulars are oblique, the lower one distinct, 

 the upper one faint. The body is very robust. The middle tibiae are spined, and the 

 hind tibiae have two pairs of long spurs. The primaries of the male have the portions 

 of the brand placed thus: (1) a long, incomplete >-- shaped piece, the upper arm 

 extending along the greater part of the second median segment to beyond the base of 

 the second median branch, and the lower along the first median branch; (2) a 

 longitudinal streak below this ; (3) a still longer streak just above the submedian 

 nervure. 



In the typical species, T. myna, the brand is somewhat modified to make room for 

 the hyaline spots, this not being the case in T. quadratics.

Dr. Staudinger has lent us a male and two females of this species. In general fades 

 it is very like Themesion certima (Hew.). The type is figured. 



THEMESION, gen. nov. 



The Tropical- American species referred to this genus, of which Hesperia certima, 

 Hew., is taken as the type, are of large size, with very long antennae, with long 

 crook, a robust body, broadly lobed secondaries, short upper spurs to the hind tibiee 

 (suggesting an affinity with Carystoides, in which they are altogether absent), and 

 no marks of sexual distinction on the primaries of the male. They all have laro-e 

 hyaline spots on the primaries (the one in the cell being geminate or divided), and the 

 base of the antennal club clothed with white scales. Unfortunately, most of the 

 specimens before us are females, though there is a male of T. certima in the British 

 Museum, and we have males of allied unnamed South-American forms that probably 

 belong here. T. certima is very like Tisias myna, which, however, has a conspicuous 

 treble brand on the fore wings in the male. Hesperia noseda, Hew. (=Proteides 

 brinoides, Moschl.), belongs to the present genus, and Carystus maroma and Proteides 

 mceros, Moschl., may also have to be included in it. 



The antennae are about, or rather more than, half the length of the costa, and have 

 an elongate club, terminating in a very long crook. The third joint of the palpi is 

 very short, blunt, and concealed, and clothed with scales. The primaries are elongate,
