28 PAPILIO. By Dr. K. Jordan. 



known, are marmorated ; the light coloiu' forms before the middle, especially laterally, "a large irregular spot; on 

 each side a subdorsal row of tubercles. The larvae are shiny and superficially resemble those of Tenthredinidae ; 

 they rest in larger numbers on leaves or the trunk and are mostljr found on Citrus. Pupa resembling a short 

 broken-off twig; the thoracic horn not long. 



P. hyppason Cr. (= hippason Esp) (10 b, c). Tailless. Pronotum spotted with red. Hindwing 



beneath Mith red basal spot behind the cell. Subcostal of the hindwing much more proximal than the 



hyppason. 2. median. Sexes different from one another, each variable in itself. cT-f. hyppason Cr. (== hippasonides 



ptilion. Grose-Smith) has a broad band on the forewing, mostly abbreviated. In d^-f. ptilion L'. & J. the band of 



the forewing is narrow and placed farther from the ceU. The ? occurs likewise in 2 principal forms: ?-f. 



amosis. amosis Cr. has a black forewing, on which scarcel}' a trace of white discal spots is visible. In ?-f. 



paraensis. paraensis Bates, on the contrary, the forewing has one or several white or yellowish white spots. These 



forms occur together, though not everywhere. — The Guianas to Para, the Amazon upwards to Peru and 



southwards to South-East Bolivia; not known from Brazil proper, Ecuador, Venezuela and (Colombia. The 



butterfly is found at the edges of swampy woods and has a swift flight. 



P. pelaus. With spatulate tail. Sexes similar, but the markings in the ? somewhat enlarged and 

 on the hindwing more numerous than in the cf. Black, forewing with oblique Vv'hite band from the costa 

 to the anal angle: hindwing with complete (?) or incomplete (cf) row of pale red submarginal spots; 

 beneath there are usually also small discal spots present, which sometimes in the S also occur above. West 

 pelaus. Indies. — pelaus F. (= ornofagus Weiclem., peleus Gmel.) (7 b) has a proportionately broad white band on 

 the fore'nang, which above, at least in the ?, also enters the extremity of the cell. Jamaica and Cuba; 

 imerius. perhaps the specimens from Porto Rico also belong here. — In imerius Godt. {= augias Men) the band 

 of the forewing is narrower anteriorty, on the other hand its last spot is on the whole broader than in the 

 preceding form, and the spots on the hindwing are smaller. Haiti. 



oxynius. P. oxynius Rhn. (= augustus Bohd.) (10b). Similar to pelaus, but the band of the foremng only 



indicated; the marginal spots of both wings large. — Only known from Cuba. Larva on Xanthoxylum, 

 gregarious by day, resting on the trunk and branches. 



epenetus. P. epCHCtus Bew. (10b). Tailless; the ? paler than the cf ; forewing without spots except at the 



margin; hindwing with large 3'ellowish white marginal spots and in the ? usually also some small discal 

 spots. — From Western Ecuador, not known from the east side of the Andes. Haensch found the larvae 

 in June in large numbers on Citrus. 



chiansiades. p. chiansiades Westu). (= chinsiades Kirhij) (lOd). On the upper surface of the forewing before 



the hindmargin a large yellowish white spot; on the hindwing posteriori}' some red discal and submarginal 

 spots, the spots of the two rows separated from one another; the tooth of the 3. radial prolonged into a 

 short pointed tail. The ? and the earlier stages not known. — Eastern slopes of the Andes of Ecuador 

 and Peru, likewise on the Upper Amazon. 



phamaces. P. pharnaccs Bouhl. (=^ phanostratus Godm. <& Sah\, polycharmus rid.) (10 c). More or less distinctly 



tailed, hindwing with two separated rows of red spots, the proximal spots in the cf often very small. — 

 Mexico, distributed from the Atlantic to the Pacific. 



erostratus. P. erostratus Westu-. (= herostratus tldr., ? = rhetus Graij) (10 c). Like the preceding species, 



but in the cf the spots on the upper surface of the hindwing yellowish white. In the ? the spots red also 

 above, larger than in the ? of phamaces, the marginal spots of both wings also somewhat larger than in 

 the foregoing species. Tail long and narrow. — Guerrero in West Mexico (where phamaces also occurs), 

 Guatemala and British Honduras. Commonest in hilly countrj' at a height of about 5000 ft. 



rogeri. P. rogeri Boisd. Forewing lighter in colour from the apex of the cell outwards, the dark basal 



area rounded distally; hindwing with suggestion of a small tail; some red spots on the disc, in two separate 

 rows, in the cf the proximal spots very small, usually only indicated; in the ? all the spots larger than in 

 the cf. — Larva not known. Yucatan and British Honduras. 



P. anchisiades. A widely distributed variable species. Hindwing posteriorly somewhat prolonged, 

 therefore more or less triangular; the tail is wanting or is only somewhat longer than the other marginal 

 teeth, yet in the ? sometimes as long and pointed as in the following species. The red spots of both the 

 rows of the hindwing on the underside partly contiguous, or at least two pairs placed quite close together. 

 Larva on Citrus, often resting together in hundreds on the stems. A very common insect, which is fond 

 idaetis. of drinking at moist places on the banks of rivers; not a forest species. — idaeus F. {^= pandion FIdr., 

 pandonius Stc/r.). Forewing usually with a distinct white spot at the end of the cell above and beneath or 

 aiidu'siades. only beneath. Central America, from Mexico to Panama. — anchisiades E.'ip. (^ anchises L. partim, 

 theramenes Fldr., pompeius Kirhy) (10 d). Very variable. Forewing with two white spots posteriorly of
