inner pair short, the outer pair longer and extending backward to the elevated 

 x; there is also a black stripe extending along each side from the x to the 

 base of each fore wing. Between the x and the two central obconical spots 

 there is an irregular cross-shaped spot, and the two depressed black points, 

 common to many species, and near the anterior extremities of the x, are also 

 present. The x and lighter lines on the mesonotum are orange. The tergum 

 is a very dark brown ; the segments narrowly edged with orange posteriorly, 

 and the lateral grooves extending down the sides from the dorsal line are 

 noticeable. The fore wings have their costal margins orange for about half of 

 their length, beyond which they are blackened ; the subcostal veins are very 

 dark brown. The first and second cross veins of the fore wings are not 

 clouded ; both pairs of wings are orange at the base with the flaps grayish 

 white. Beneath lighter colored, the legs orange, streaked and spotted with 

 testaceous. The abdomen with the segments darkened along each side. Oper- 

 cula light orange, a little less than half as long as the abdomen, and rounded

 in profile showing a considerable protuberance extending backward from its 

 central portion, below which it terminates as a curved claw bent inward ; 

 when seen from behind of the wish-bone shape, stouter and with the extremi- 

 ties more bent toward each other than in the next species.
