 a transverse posterior mark and spot at base of fore wing, yellow. Anterior coxae yellow ; femora 

 black marked with a little yellow; tibiae yellow and orange; tarsi orange. Abdomen black with 

 a broad bright yellow band on the posterior edge of each segment, those of the posterior segments 

 much widened ; sometimes the first to fourth segments have the bands very narrow and the last 

 three segments are wholly yellow. Underside similar to the above. Fore wings thinly clothed 

 with dull orange brown scales, bordered with deep brown black along the costa and inner margin, 

 discal mark slightly indicated. At the base of the wing is a short transparent streak, and at the 

 hind angle is a transparent area. Underside paler than above, washed with orange. Hind wings 

 transparent, with an opalescent lustre, margin very narrow brown. 



Expanse : 27-35 mm - 



Habitat. — Rhode Island, New York, Pennsylvania, New Jersey, Illinois, Ohio, Minnesota. 



Type : One female. Coll. Hy. Edwards, Am. Mus. Nat. Hist. 



In the larval stage this insect lives in the solid wood of the red oak. The 

 moth appears from late in May until July.

Male. — Top of head and face black ; palpi orange, black at base ; collar orange ; antennae pec- 

 tinate, black, orange at base, fulvous at tip. Thorax black ; patagia at tips, a large spot at posterior 

 part, and a small spot at base of fore wing light orange. Abdomen rich orange, with a narrow black 

 ring at the anterior part of each segment. Legs rich orange, hind femora partly black. Fore wings 

 rich purplish brown, slightly orange at the base and along the costa to nearly the middle of the wing ; 

 above the anal angle, between veins C 1 and C 2 , is an opalescent, transparent streak ; underside washed 

 with orange basally. Hind wings dull yellowish, transparent, strongly opalescent ; veins, discal 

 mark, and narrow margin violet brown ; underside, with the veins and line in outer margin, orange. 



Female. — Similar to the male, with the antennae simple. 



Expanse : Male, 32 mm.; female, 43 mm. 



Habitat. — Florida (Enterprise). 



Type : One female. Coll. Hy. Edwards, Am. Mus. Nat. Hist. 



Nothing is known about the early stages of this species, but probably, like 

 its congener (M. simulans), it lives in oak. It is allied to M. simulans but the 

 abdomen is bright orange instead of lemon yellow.
