794 THECLA, By Dr. M. Draudt. 



91. Critola- Group. 



crUola. Th. critola Hew. (157 i) is an entirely isolated animal. Above lustrous ultramarine-blue with narrow 



black margins and a large black scent-spot. Beneath grey with brown transverse dashes, behind them on the 

 forevvings with a rusty-brown band and on the hindwings a chain of light-yellow small spots bordered distally 

 by brown; the two small anal spots are yellow bordered above by brown. Mexico. 



92. Hesperitis-Group. 



hesperrfis. Th. Siespcritis Btlr. {= cabiria Hew., perdistincta Kaye) (157 i) is above black-brown, only on the 



hindwings beginning from the lower radial vein towards the proximal margin there is a blue sprinkling with 

 a red .spot in the anal lobe. Beneath brown, at the proximal margin of the forewing a little lighter : on the forewings 

 an almost straight, darker brown, distally somewhat lighter tinged postdiscal line as far as the lower median 

 vein, before the border an indistinct, darker line. On the hindwings the postdiscal line begins with a small spot 

 being a little distally inclined; this line is black Avith a distal white tinge and, towards the proximal margin, 

 proximally sometimes strewn with orange; the angle of the W, resting f)n the lower median vein does not reach 

 so far towards the margin as the anal one; anal spot black, tiie spot of the tail copper-red with a black triangle 

 liKjiihris. in it, between both white dusting on a black ground. — In more southern specimens, = lugubris Mf^rhlr.. the 

 spot of the tail is more brown. Most widely distributed from Mexico to Brazil. 

 annua. Th. afuma Heu\ (157 i) looks very nuich like tiie following above, but it differs by the broader lilack 



distal margin of the hindwings. Beneatii it is marked like the preceding: the red colour at the anal sjiots is 

 either absent altogether or it is just as extensive as in hesperitis. Guiana to Brazil. 

 cfiiDisaa. Th. camissa Hew. (= vespasianus Btlr., chariclorus Btlr.) (157 k) is above magnificently ultramarine- 



blue with a violet lustre, the apex broadly black, on the median projecting pointedly towards the base. Distal 

 margin narrowly black, the costal area of the hindwing broadly black. The under surface olive-yellowish, lustrous ; 

 marked as in hesperitis, the red spot of the tail reaches as far as or almost as far as the discal side of the W. 

 Guatemala to Peru. 



.'ihiiasca. Th. sitiiasca sp. nov. (157 k) differs from the preceding above by the increased blue colour being situate 



only below the lower median vein, the inner-marginal vein remains broadly black; on the hindwings there 

 are only towards the anal angle some violet scales. Beneath there is no difference. Colombia (Rio Negro). 



f/cdrosia. Th. gedrosia Heu\ (157 k) is above blackish-brown, both wings towards the base with a deep violet- 



blue tinge. Beneath dark-brown, marked as he.speritis, the black of the postdiscal line more intense, the W 

 more uniform, distinguished by the very large, red anal spots; in the surroundings of the .spot of the tail there 

 is on both sides extensive whitish dusting. Amazon. 



devia. Th. devia MschJr. seems to be very closely allied to the following. On the upper surface the forewings 



are blackish-blue, the hindwings lighter blue. The ground-colour beneath is grey-brown, the marking as in 

 xeneta, the 2 red-yellow anal spots distinct. Length of forewings: 13 mm. Surinam. 



xcnclci. Th. xeneta i/eH'. (157 k)isabove dull greenish indigo-blue, the forewings towards the margin with a bright 



ultramarine-blue reflection: the under surface is sooty blackish-brown, with the same markings which are 

 distally somewhat lighter tinged and grow somewhat more purely white only with in the scope of the W; in 

 the northern, mostly a little lighter specimens some deep red-brown becomes visible at the anal angle, dis- 

 appearing entirely in the sooty-black area in more southern specimens. From Guatemala to South Brazil. 



iHirhinda. Th. partunda Hew. (= origo Godm. dj Salv.) (157 k) is of a deeper, more intense blackish-brown, on 



the hindwings the metallic-blue spot extends close to the base. The under surface is lighter, the anal spots 

 with a broad red margin. Panama to the Amazon. 



rih-in-ia. Th. vitfuvia Hew. (157 c) seems hitherto to be known typically in but one specimen. Forewings black, 



at the proximal margin broadly ultramarine-blue, hindwings not metallic blue, at the distal margin broadly 

 blackish-brown like at the costal margin. Beneath like the preceding, but the spot of the tail is not red, but 



jorliiiia. dark-brown. The type originates from Para. — fortuna Drc. is above and beneath the same, but the spot of 



lorqueor. the tail is bordered by red. Peru, Amazon. — torqueor Drc. is above somewhat lighter blue, this colour on the 



indiyo. forewing reduced, beneath like fortuna. From Biit. Guiana. — indigo Drc. has above on the forewings only 



a narrow blue stripe at the proximal margin and is beneath coloured as vitruvin; this form from Brazil is con- 



(inJTfifia. siderably smaller. — anfracta Drc. has above one-coloured greenish-black forewings, for the rest like the type. 

 Described from Peru. 



i}Mm<i. Th. thama Hew. (158 a) is smaller and above very lustrous metallic-blue, more greenish than xeneta, 



the costal margin of all the wings very broad, the distal margin narrowly black. Beneath somewhat lighter 

 than the said species, about as partunda with bright red spots, also the W is beneath filled up with red and 

 proximally bordered the same. Panama to Colombia.
