known, are marmorated; Ihe liglit colour 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 mostly found on ( 'itrus. Pupa resembling a short 

 hroken-ofif twig ; the thoracic horn not long. 



P. hyppason 'V. (= liipi)ason Esp.) (101), c). Tailless. Proiiotum spotted with red. Hindwing 



beneath with red liasal sjiot ])ehiiid the cell. Subcostal of the hindwing much more proximal than the 



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



pti/ion. (Ti-ose-Smith) has a broad band on the forewing, mostly abbreviated. In o^'-f ptilion B. & J. the band of 



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



amosis. amosis Cr. has a black forewing, on which scarcely a trace of white discal spots is visil)le. In $-f. 



paracusis, 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 ("olomlna. The 



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



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

 on the hindwing more numerous than in tlie cf. Black, forewing with oblique white band from the costa 

 to the anal angle: hindwing with com])lete (?) or incomplete (d) row of pale red submarginal spots: 

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

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

 the forewing, which above, at least in tlie ?, also enters the extremity of the cell. Jamaica and (Juba: 

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

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

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



oxynias. P, oxynius Hh)i. (=: augustus Boisf/.) (lOli). Similar to pcluug, ])ut the band of the forewing 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. 



epeneius. p, epenetus Heir. (10b). Tailless; the ? paler than the cf ; forewing without spots except at the 



margin ; hindwing with large yellowish 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 Westw. (= chinsiades Kirbii) (lOd). (Jn the u])per surface of the forewing before 



the hindmargin a large yellowish white spot; on the hindwing posteriorly some red discal and submarginal 

 spots, the spots of the two rows separated from one another; the tootli 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. 



pharnaces. P. pharnaces Dotihl (= phanostratus Godm. & SaU., polycharmus iid.) (10 c). More or less distinctly 



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

 Mexico, distributed from the Atlantic to the Pacific. 



erostratus. P. erostratus Westw. (= herosti'atus Fldr., ? =: rhetus (h-aij) (10 c). Like tlie 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 tiie ? of pharnaces, the marginal spots of both wings also somewhat larger than in 

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

 Guatemala and British Honduras-. Commonest in hilly country 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 distaliy; 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 distrilnited variable species. Hindwing posteriorly somewlmt 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 

 idaeus. of drinking at moist places on the banks of rivers; not a forest species. — idaeus F. (= pandion Fldr., 

 pandonius Stcji-.). Forewing usually with a distinct white spot at the end of I lie cell above and beneath or 

 andiisiades. only beneath. Ck'ntral America, from Mexico to Panama. — anchisiades £^7^. (= anchises 7>. paitim, 

 theramenes lldr., pompeius Kirhy) (10 d). Very variable. Forewing \\\\\\ two white s])ots posterioi-ly of
