838 PYRRHOPYGE. By Dr. M. Deaudt. 



rhacia. P. rhacia Heic. (162 b) is at once discernible from all the species by the white palpi and the whi^e- 



striped anterior femora, as well as the red thorax. Minas Geraes. 



procuhis. P. proculus Hpffr. {= zeleucus Erichs., nee F.) (162 b) differs from the preceding by only the anterior 



head being red. the posterior head being black as far as the eyes. Guiana. 



ro.^cics. P. roscius Hpffr. exhibits a red belt across the middle abdominal rings, but the head is quite black, 



only the shoulders being spotted red and the anus red. From Brazil. 



duleinea. P. dulcinca Pldtz (162 c) has 3 white transverse lines on the head: on the forehead, between the 



antennae and on the hindhead; palpi, base of shoulder-covers and apex of abdomen are red, the shoulder-covers 

 finely bordered with red or orange-yellow. Mexico to South America. 



semidentaia. P. scmidentata Mnh. This species has, like the 6 following ones, a white base of the hindwing beneath, 



also the base of the forewing is white; the fringes of the hindwing are speckled black on the ends of the veins, 

 on the forewing white as far as the upper median vein, from there to the apex black. Colombia. 



intersecta. P. iiitersecta H.-Schdff. (162 c) differs by the fringes of the hindwing being only speckled in the proxi- 



mal half, those of the forewing being almost entirely white. The fed head is spotted black, the thorax quite 

 black. South America. 



denticulata. P. detiticulata H.-Schdff. deviates from the preceding by the fringes being yellowish at the base. Head, 



prothorax and apex of abdomen are red. South America. 



fluminis. P. flumitiis Btlr. (162 c) has unspeckled fringes like the 4 following species. On the brownish under 



surface of the forewing only the costal-marginal base is white, the fringes blackened only at the extreme apex. 

 Amazon. 



hixae. P. bixae Cr. (= maenas F.. tiribazus Plotz) has the whole base of the forewing beneath blue-white, 



the fringes of the forewing are smoky from the upper median vein. Guiana. 



latifasciata. P. latifasciata Btlr. (162 d) is recognizable by the extraordinarily broad white basal spot of the hind- 



wing, whereas the base of the forewing remains quite black; fringes like in hixae. Colombia and Peru. 



phidias. P. phidias L. (162 c, d) differs from latifasciata by its smaller white basal spot, the fringes being only 



brownish from the lower radial vein towards the apex. From Guiana and South America. 



infantilis. P. infantilis Drc. (162 c) is smaller than the preceding, the white spot on the hindwing beneath is 



placed somewhat more into the middle of the wing, indistinct and strewn with a dark tinge. Peru. 



agenoria. P. agenoria Hew. (162 d) has, like the 6 following species, a red-spotted proximal angle of the 



hindwing, and is recognizable by its black head and abdomen (only the collar being red) and by the under surface 

 of the hindwing being all black. Known from Para. 



truor. P. cruor Drc. (166 a) entirely resembles agenoria, but in the middle of the forewing it shows a broad 



transverse band of modified, differently placed scales, which stands out against the ground of the forewing 

 indistinctly darker. Described from Pozuzo (Peru). . . 



sanies. P. sanies Drc. (164 d) entirely resembles cruor, but the band of the forewing is here white, semi- 



diaphanous and somewhat opalescent, it also runs more obliquely. From La Paz (Bolivia). 



sty.r. P, styx Mschlr. (= anina Plotz) (166 a) has beneath a white-spotted base of the hindwing; head 



and prothorax are red, the red spot of the hindwing is very large and occasionally extends beyond the lower 

 median vein. Colombia. 



paasova. P. passova Hew. (162 d) differs by an entirely black prothorax and the spot of the hindwing being 



bordered with black; the basal spot of the hindwing beneath is decidedly bluish. Amazon, Bolivia. 



gorfyna. P. gortyna Hew. (166 a) is at once recognizable by the hindwing being spotted green-white above 



in the middle. From Ega. 



galgala. P. galgala Hew. (= strigifera Fldr.) (162 d) cannot be confounded with any other species for the 



yellow oblique line exhibited by the forewing above, by the hindwing also beneath. The body is black except 

 the red hindhead and apex of the abdomen. Colombia. Brazil. 



gellias. P. gellias G. di S. (162 d) exhibits along the distal margin of the hindwing high, triangular, silvery 



blue spots. Costa Rica. 



gazera. P. gazcra Hew. (162 d) differs from gellias by the broader and rounder shape of its wings, the distal- 



marginal spots are less high and extend only to the upper radial vein. South America.
