!)20 BUTLERIA: DALLA. By Dr. M. Deaudt. 



Subfamily: Pampliilinae Wis. 

 G r o 11 p A. 



Antennae with a bent, gradually tapering; club. Terminal joint ot the palp niodorately long, porrect. o forewing 

 in the Anierican species without a stigma. 



66. Genus: ISiitleria Ky. 



This genus which was formerly combined \\\i\\ the following by the name of Butleria now only contains 

 yet some species from South Chile of a characteristic exterior. Antennal club rather obtuse, palpi shorter, 

 beneath hairy. Forewing at the base convex with an obtuse apex. Posterior tibiae with one or two pair of spurs. 



lisea-(j((ftala. B. biscxguttata Phil. (179 c) is above blackish-brown with 6 minute orange spots which are in the 



$ partly larger and increased by two; the $ besides exhibits behind the cell of the hindwing a larger, roundish 

 orange spot. Beneath the forewing is blackish, at the costal margin and ajjex red-brown as the hindwing, the 

 latter with a Itroader, blackish discal shade and an undulate marginal band. It flies in dense forests in South 

 Chile. 

 opvrta. B. aperta Fldiz (179c) is allied to the preceding. Above dark blackish-brown with 3 small yellow 



discal spots arranged in a triangle, and 3 small subapical dots. Hindwing luimarked. Beneath the costal half 

 of the forewing, the costal margin and the distal-marginal third of the hindwing are red-brown, on the hind- 

 wing 2 lurdulate, dark submarginal lines. Patria not stated. 



rnhlii-(((i(i(.-<. B. valdivianus Phil. (= exornatusi^Wr.) (179 c) is above much more intensely spotted yellow, especially 



in the submecUan space, and the hindwing shows a submarginal row of yellow dots; fringes yellow. Beneath 

 the forewing is yellow, spotted black, the hindwing more brownish-red with 3 transverse rows of silvery white 

 spots partly bordered with black. Chile. 

 fIacoiii((r(i- B. flavomaculata Blch. (= vicina Reed., V paniscoides Reed.) is a not cj[iute certain species, it seems 



to be smaller than the preceding, but otherwise very much like it, easily discernible by yellow instead of silvery 

 white spots beneath. Probably also 'paniscoides Blch. belongs hereto, the description of which is too insufficient 

 as to allow its identification. Chile. 



B. facetus Pldtz (179 b) is allied to jlavomacuhita. Above black with numerous small yellow puncti- 

 form spots and a larger one at the cell-end. Hindwing with a light discal diffu.se spot ; fringes j'ellow speckled 

 with black. Beneath the black, j^ellow-spotted forewing exhibits a reddish-yellow costal margin and distal 

 margin. Hindwing reddish yellowLsh-brown with a large trisected. Isabel-coloured spot in the inner-marginal 

 area, 2 s)nall ones in the basal area and one at the costal margin above them. From Argentina and Chile. 



pobjsjnhi.-i. B. polyspilus Fldr. (179 b, c) is again difficult to identify. It is somewhat larger, blacker, the discal 



spot of the hindwing larger, fringes of a piner yellow. Hindwing beneath lighter reddish-yellow, without any 

 black markings, so that the white spots are situate directly on the reddish ground. This species, according 

 to Elwes, flies more on open grass-plots in Argentina and Chile. 



■paniscoides. B. patiiscoides Blch. (= caucpienensis Reed.) is a doubtful species which, as was mentioned above, 



probably is synonymous with flavomaculata, or perhaps also belongs to facetus. both of which exhibit yellow 

 instead of silvery white spots on the hindwing beneath. Stated from Chile. 



fr((lic(>tfi)(s. B. fruticolens Btlr. (= tripunctatus Mab.) (179 c) is a somewhat larger, most variable species. Above 



black, on the forewing with 4 to 9, on the hindwing with 2 to 4 small orange spots. Beneath the forewing is 

 blackish, at the costal margin and apex reddish-yellow with the spots of the upper surface; hindwing orange, 

 in the disc lighter yellow, at the proximal margin blackish, between the two coloiu-s a whitish ray. The forms 

 denominated by Butler: tractipennis, quadrinotatus and pulcher only differ by the number of the small yellow 

 spots. Chile, rising up to 4(K)() ft., and varying according to Elwe.s more in the maritime districts than in 

 the mountains. 

 phdippii. B. philippii Btlr. is very closely allied to fruticolens, differing only by a silver^' stripe on the hindwing 



beneath. Apparently rare and hitherto only found in the Province of Valdivia. 

 citKs. B. Vitus Ploiz (179 c) is likewise closely allied, considerably larger with nuich larger yellow spots and 



two silvery stripes on the hindwing beneath with 3 silvery .spots between. Hindwing much darker, only at 

 the costal margin slightly yellow. From Chile. 

 .s-ofoj. B. sotoi Reed, is likewise a very rare species very closely allied to the preceding. It differs by the 



bases of all the wings being strewn with yellowish, and a silvery white spot on the hindwing beneath. From 

 South (Ihile, flying in dense forests. 



67. Genus: l>alla Mah. 



Antennal club with a longer point than in the preceding genera, palpi somewhat longer, especially 

 the terminal joint slender. Forewing at the base not so convex. Posterior tibiae fringed with 2 pair of spurs. 

 Numerous species mostly marked black and reddish-yellow.
