more niimerons ; c? with tliree-eorntTcil or three-tnfted tail, side-tufts not developed 

 ia ? ; seventh steriiite of ? long trapeziform, without s]iiiies. Merum of luiJcoxa 

 with faint iudicatiou of an angle. Legs slender, smooth-scaled : midtarsus with 

 rndimentar}' comb, no comh to hindtarsns ; spurs very unequal, long terminal one 

 of hindtibia rather longer than the second tarsal segment ; last segment of hind- 

 tarsus (claw excej)ted) shorter than fourth. Di.stal margin of forewing regularly 

 dentate, snbbasal patch of modified scales of underside rounded-truncate at end, 

 not acuminate ; II- of hindwing central, D'' longer than D', lower angle of cell 

 acute. 



cj. Tenth abdominal segment of the same type as in Pscndosphin.r, Pfrigonia, 

 Mu(lon/x, etc., both the tergite and sternite divided into two lobes ; the tergal 

 lubes flattened, obtuse, hairy ; the sternal ones long, conical, acute, strongly 

 chitinised, curved at end, contiguous with the tergite, and a little longer than this. 

 Clasper elongate, toiigue-sha])ed, narrowing distally ; a i)atch of many erect, small, 

 lanceolate friction-scales; harjie (PI. XLV. f. 2i)"-24) jiroduced into an obtuse jiroces-s, 

 which is more or less dilated at end, here sometimes sinuate, its surface smooth. 

 Penis-sheath (PI. LIU. f 8. i)) with a brush of spines inside, which break ofif' easily 

 (being j)resent as a rule only in fresh specimens, which have apjjarently not 

 copulated) ; a series of teeth at the right and left edges of the sheath. 



?. Eighth tergite weak, membranaceous for the greater part; vaginal plate 

 with the lateral distal edge more or less free, ridge-like ; distal jiart scaled, mesially 

 triangular ; orifice jjroximal, pear-shaped, situated in a large cavity formed by a 

 smooth proximal membrane. 



Larva cylindrical, somewhat flattened, head strongly slanting in side-view ; 

 horn sliort ; thorax with a black mesial patch anteriorly on third segment, 

 generally marked with red and white; dorsal surface darker in colour tlian sides 

 an<l ventral surface, the two colours often separated by a longitudinal pale line. — 

 l'\iod-plants : Carica ; Morrenia ; Jittrojthu {^). 



Clirysalis glossy, polished, pale brown, wings striped with black, abdomen with 

 short transverse black dashes. 



Ihih. Tro])ical and subtropical America ; some sjiecies wandering northward 

 well into tlie Nearctic ri'gion, one as far as Canada. 



The s[)ecies are not very difKcult to distinguish if one keeps in mind that the 

 sexes of several species are remarkably different, the d" c? of these being very mucli 

 darker on the forewing than the respective ? ? . Owing to this sexual dichromatism, 

 to individual variability, and to the carelessness of some authors, the synonymy of 

 some sjjecies is mnch involved. But the way was cleared for us, thanks to Mr. W. 

 Schaus, who corrected a number of errors committed by Grote and others. We 

 fear we have not put into the right jilace some of the species enumerated by Herr 

 von Bonuinghansen from Itio de Janeiro under Grotean and Boisduvaliau names.
