VACERRA; TIRYNTHIA. By Dr. M. Drafdt. 



Hindwing in the disc dusted with purple; below the hyaline spots a large, triangular, brown spot narrowly 

 bordered with purple; behind the hyaline spots 3 ferruginous spots separated by the veins. Expan.se of wings: 

 36 to 40 mm. Mexico (Guerrero, Cuernavaca). 

 dissuUus. Th. dissultus sp. nov. (185 a) is a smaller species, above intensely reddish-yellow, the spots yellowish, 



the submedian spot quite ochreous-yellow, the cell-spot very small, only 3 postdiscal spots; hindwing with 4 

 narrow, light ochreous, small spots, the two middle ones transj^arent and more white. Beneath duller brown 

 without any red or reddish-yellow tints, apex of forewing parted by white, before it with a deep brown triangular 

 spot proximally bordered with white and exliibiting a white dot at the costal margin. Below the base of the 

 costal margin of the hindwing a white stripe and through the middle of the cell above the radial veins as far 

 as the apex a white stripe from the middle of which a branch extends to the middle of the costal margm, 

 in the middle of which a small brown streak-spot is situate. Below the cell 2 large, blackish-brown spots on 

 each side bordered with whitish, the proximal one being smaller; the two postdiscal hyaline spots are likewise 

 distally bordered by dark brown spots; proximal margin dark brown. South Brazil. 

 dahnani. Th. dalmatli Latr. (185a) is twice as large, otherwise very similar; the hyaline spots are larger, on 



the forewing without the yellowish tint; bases of wmgs not so reddish-yellow, more olive-yellowish. Beneath 

 very much like dissultus; the white longitudinal stripe through the cell of the hindwing and its costal-marginal 

 branch are abseiat, the cell and the apical costal-marginal half are monotonously pinkish-grey or whitish ; the 

 blackish— brown spots below and behind the cell are very prominent, the spot situate towards the base below 

 the cell being very small. Fringes at the anal angle ochreous-yellowish. Mexico to Colombia, South Peru. 

 guerreronia. — In f. guerrcronis Dyar (185 a) from West Mexico the blackish-brown spot of the hindwing beneath is much 

 larger and triangular and reaches beneath to the lower end of the white hyaline spot. 



119. Genus: Vacerra G. & S. 



As Thespieus, but on the forewing the lower median vein rises much nearer at the base, and the stigma 

 consists of two narrow, scarcely visible longitudinal stripes, a short one below the lower median vein and a 

 longer one above the base of the submedian. 

 bonfilsli. V. bonfilsii Latr. (Mab. Gener. Ins. 17 d, p. 148) has unfortunately remained unknown to us. 



litana. V. litana Hew. {= caprotina H.-Schdff., socles Plotz, aeos Plotz, cabenta Plotz) (185b) looks above 



like Thespieus macareus (184f ), body and bases of wings with dull ochreous hair, easily discernible by the entirely 

 different, indistinct stigma. Hindwing beneath at the base cerise, distally more lilac-grey with a yellowish- 

 white band and cell-spot. From Mexico to the Amazon. 

 egla. V. egla Hew. (185 b) is similar, smaller, the cell-spot on the forewing divided into two, all the spots 



narrower, the band of the hindwing longer, all the spots in it equally broad. Beneath lighter, hindwing more 

 mixed with cerise, with a bone-colom-ed white band. Mexico, Nicaragua, Panama. 

 Uchares. V. lachares G. c& S. (185 b) is very similar, but larger, below the subapical spots of the forewing 



two more spots, the band of the hindwing is more pointed towards the proximal margin. Beneath much darker 

 than egla. From Costa Rica. 

 caniola. V. cailiola H.-Schdff. (= canente Btlr.) (185c). Above as litana, beneath the hindwing exliibits a 



straight white band from the apex to the anal lobe, not so far as the angle. In the ^ the cell-spot is divided 

 into two. Costa Rica. 

 dalhna. V. dalima Plotz (185 d). Blackish-brown, on the forewing with 3 postdiscal spots, 2 subapical ones 



and one minute cell-spot, on the hindwing with a narrow, white postcellular ti'ansverse band of 4 small spots. 

 Beneath as above, but very much didler brown, m the disc of the forewing black. Brazil. 



120. Genus: Tiryiithia G. d- S. 



Differs from Vacerra by a longer antennal club; the costal margin of the forewing is bent convex at 

 the base, the cell is shorter than ^/^ of the costa ; the middle tibiae without spines and the (J is without the scent- 

 scale apparatus. 

 cnnjlna. T. conflua H.-Schdff. (185 c) resembles Vacerra egla above, but it has no cell-.spot. The hindwing 



shows a short, ochreous-yellowish postcellular band divided by the veins. The hindwing beneath is light brown 

 with a broad, straight white band from the apex to the darker middle of the proximal margin which it does not 

 reach. Nicaragua to Parana. 

 cinica. T. citlica Pldtz (185 b, c) differs from conflua by smaller white spots increased by a cell-spot; the 



hindwing only shows a roundish discal spot. Beneath scarcely different from conflua, but in the middleof 

 the costal margin is a yellow spot, and the inner-marginal area is broadly greyish-white. From Para. 

 osca. T. osca Plotz (185c) is doubtfully placed here. Above blackish-brown, with a basal green reflection; 



forewing with a large, quadrangular cell-spot and 2 behind it, as well as 3 subapical dots. Hindwing with 2
