Larva in 2 forms: -—- 1. In July to August on vine, gregareous, at first entirely pale yellow with white

ical form of americana. 
H. ruemelii Druce (9g). Foretibia without spur. Dull blue-black, upper side of head, the collar and ruemelii. 
the anterior portion of the mesonotum yellow. Forewing with 11 veins, subcostal stalk short, upper median

or absent. —- Texas. 
H. brillians Barn, and McDun. (= coracina Dyar, nec Clem., err. determ.) (9 h). As glossy greenish brillians.

H. guatemalena Druce (9h). A small species. Dull black. Wings subdiaphanous. Foretibia without guatema- 
spur. Forewing with 11 veins, stalk of subcostals 2 and 4 (3 absent) very short. —- Guatemala, 1 $ in the lena '

H. mexicana Schaus (9h). Not known to we in nature. A small dull black species with semitrans- mexicana. 
parent hindwing. Pectinations of antenna longer than in americana. — Mexico: Vera Cruz.
