MOTHS OF THE GENERA MULONA WALKER AND LOMUNA, 

 A NEW AND CLOSELY RELATED GENUS (ARCTIIDAE: 

 LITHOSIINAE) 



By William D. Field 



The two genera of moths * treated in this paper are found only in 

 the Greater Antilles and the Bahama Islands. Until the present time 

 they have been treated as a single genus with three species, Mulona 

 lapidaria Walker, Mulona nigripuncta Hampson, and Mulona grisea 

 Hampson.^ A careful study of the 47 known specimens from the 

 collections of the United States National Museum, the British 

 Museum (Natural History), the American Museum of Natural 

 History, the Carnegie Museum, and Cornell University, disclosed 

 two genera and six species involved in the complex. 



Palpal, antennal, and venational characters are identical in the 

 two genera treated in this paper and are given here to avoid repetition 

 in the generic descriptions. Labial palpus uptm*ned, reaching middle 

 or slightly above middle of frons. Antenna of male and female fili- 

 form and gradually more slender to the tip; each subsegment with 

 two pairs of bristles, one from near or above middle of ventrolateral 

 margin of subsegment, the second much smaller and just behind the 

 first; subsegments pubescent. Venation of forewing with vein 2 from 

 middle of cell or from just before or after middle, downward curved 

 at base; vein 3 from just below lower angle of cell; veins 4 and 5 sepa' 

 rate, 4 from lower angle, 5 from slightly above lower angle (in one of 

 the 5 specimens of Lomuna nigripuncta Hampson, 4 and 5 are con- 

 nate or extremely short stalked); vein 6 from below upper angle of 

 cell; vein 9 from stalk of 7 and 8 or rarely 7 from stalk of 8 and 9; 



1 The species Autoceras phelina Druce was placed in Mulona by Hampson (Catalogue of the Lepidoptera 

 Phalaenae in the British Museum, vol. 2, p. 387, 1900). It does not belong in Mulona and was transferred 

 to the genus Gaudeator Dyar by Forbes (Bull. Mus. Comp. Zool., vol. 85, No. 4, p. 18.3, 1939).
