THE PERICOPID LARV/E IN THE NATIONAL MUSEUM 63 



The above synonymy refers to the Antillean form. The form in the 

 Greater Antilles (rica Hubn. = er^ofe Walk, = f/ommgonis Butl.) is 

 darker and with less red than the form of the Lesser Antilles {vinosa 

 Drury). The specimens from Porto Rico are intermediate and connect 

 the two. The species, or a series of subspecies, is widespread over the 

 mainland, from southern Brazil to Mexico. The oldest name for the 

 continental form is syma Walker, but described without locality or indi- 

 cation of sex. It has no red at all. Trinidad would seem its most likely 

 place of origin, and it should be a female. Other neimes are rufilinea 

 and partita Walker from Brazil, transita Moschler from Surinam, leuco- 

 ph&a Walker from Venezuela, sora Boisduval from Guatemala, osiha 

 and choma Druce from Ecuador, and the aberrant chthonophyla Druce 

 from Mexico, which is probably a distinct species. The ordinary Mexi- 

 can form is the same as sora Boisd.=/eucop/j<Ea Walk. In Jamaica, a 

 curious form, halizoa Druce, occurs, whether species or aberration can 

 not be stated at present. The fore wings are entirely suffused with red, 

 the subapical white band broken into spots by the veins. I have seen 

 nothing like it from euiy other islamd. 



Larvae sent by Mr. Thos. H. Jones from Porto Rico do not differ from 

 a specimen from Jamaica before me. The tubercular arrangement differs 

 from Composia in the complete fusion of the two upper warts on meso- 

 and post-thoracic segments, and the reduction of tubercles i eind iv to the 

 single-haired condition. The eggs are flatter than in Composia, being 

 hemispherical, but otherwise similar. In the larval coloration, the banded 

 effect, so chauracteristic of the family, appears rather weakly, affecting only 

 the prominent segments, joints 5, 6, I 1 , 1 2, and I 3, the posterior banding 

 being farther back than in Composia. It is not shown in stage I, as in 

 that genus, but begins first in stage II by an emphasis in the pigment of 

 the wairts on those segments, which, in stage III, begins to spread onto 

 the skin, more so in successive stages until the bands axe formed. The 

 wart-hairs are sparse and coarse, moderate in length, without any long, 

 differentiated hairs as in Composia. Mr. Jones indicates five larval 

 stages, but his materijJ shows six, and I should not be surprised if seven 

 were found, as in Composia, at least occasionally.
