ARCTIIDAE AND CTENUCHIDAE FORMERLY IN AUTOMOLIS 57 



of thorax orange-yellow with large, iridescent greyish brown and blue medial patch anteriorly. 

 Pleural and ventral surfaces of thorax orange-yellow except for dark greyish brown patch 

 behind eye. Tymbal organ with from 45 to 50 grooves. Coxa, trochanter and femur of 

 all legs orange-yellow; femur with greyish brown distal patch edged proximally with yellowish 

 white. Prothoracic tibia dark greyish brown with yellowish grey patch near base and at about 

 two-thirds distance from base on front surface, with some white scales on outer surface proximally 

 and orange-yellow scales concealing epiphysis. Prothoracic tarsus dark greyish brown, with 

 white proximal bands on two basal segments. Inner surface of mesothoracic tibia orange- 

 yellow, outer surface with yellowish grey proximal area bordered at base and in middle of leg 

 with dark greyish brown and with dark greyish brown distal band edged proximally with 

 white; tarsus as prothoracic tarsus but third segment also with white proximal band. 

 Metathoracic tibia orange-yellow, with dark greyish brown zone at proximal and distal ends 

 (the latter edged proximally with white) ; segments 1-4 of tarsus yellowish white with greyish 

 brown terminal band to each segment; distal segment of tarsus greyish brown. Forewing 

 venation as fernandezi (Text-fig. 15). Upper surface of forewing orange-yellow, with iridescent 

 green and pastel grey basal marking and three similarly coloured, medial spots and pre-apical, 

 oblique band. Under surface of forewing as upper surface but deeper yellow; basal marking 

 very weakly marked except at costa; two proximal, medial markings dark brown; distal, 

 medial marking similar, but less strongly marked; pre-apical band dark brown, most strongly 

 marked at costa and towards outer margin of wing. Hind wing orange-yellow on both surfaces; 

 venation as in Text-fig. 16; hair-pencil present on under surface in folded anal area, closely 

 associated with zones of androconial scales (PI. 26). Wings otherwise without recognizable 

 zones of androconial scales. Abdomen orange-yellow. 



$. As $, but antenna less strongly biserrate, outer margin of forewing more strongly convex 

 and anal area of hind wing unmodified. 



Forewing length: g 18-5-19-5 mm; $ 21-5 mm. 



^ genitalia. Approximately bilaterally symmetric. Valve with short, digitate, membranous, 

 apical process. Anterior margin of tegumen produced posteriorly on either side as flat plate. 

 Uncus with pair of large basal processes. Vesica of aedeagus with six main lobes, variously 

 spinose or scobinate. 



$ genitalia. Corpus bursae pyriform, sclerotized anterodorsally; appendix bursae bilobate. 

 Ostium placed to left of medial line in single available specimen (possibly distorted). Lamella 

 postvaginalis swollen laterally; medial sulcus broad, weakly scobinate. 



The species tripunctata is apparently unknown outside Costa Rica and Panama, 

 unlike the remaining four species of Emurena which are South American. The 

 male scent-producing hair-pencil of tripunctata is not therefore currently involved 

 in species recognition functions between Emurena species, although there remains 

 the possibility of a past function of this kind if the range of the related quinquepunc- 

 tata once overlapped that of tripunctata.
