[871 Otf SOME NEW SPECIES OF CERURA. 199 



may be distinguished from all others known to me by the 

 black marking cf the veins sub-apically. The conspicuous 

 black bands of the abdomen above, in one example (the $ , the 

 $ being without its abdomen) may also prove to be a good dis 

 tinctive feature. 



Cerura Candida n. sp. 



Antennae white, with black pectinations of considerable 

 length in the ? . Palpi porrected, white, outwardly with 

 black hairs. Front, patagise, thorax and collar white the 

 latter with a single fuscous band. Abdomen white, the seg 

 ments on their anterior border with a few dusky hairs ; beneath 

 white ; anal region, pale brown. Legs white, banded with 

 black ; tarsi black, banded with white. 



Primaries, silvery white, with four interrupted black bands 

 before the discal spot the discal spot forming a small oval 

 ringlet followed by three interrupted black bands, and a 

 fourth heavier one at the apical and anal region ; the usual 

 line of eight intranervular marginal blacks spots, extending on 

 the fringe, less conspicuously marked than in C. multiscripta. 



Secondaries wholly white, without marginal spots, showing 

 faintly, by transparency, the discal dot of the under surface. 



Beneath, primaries with the outer lines of the upper surface 

 heavily marked on the costa, arid a dusky cloud behind the 

 cell. Secondaries with a fuscous spot on the outer third of 

 the costal margin. 



Expanse of wings, 1.75 inch ; length of abdomen, .8 inch. 



Habitat. Kansas. 



From a specimen in my Collection, received from Mr. H. 

 Strecker. 



This beautiful species is allied to C. scitiscripta Walk., * and 

 C. multiscripta Blley.f It cannot be the former, which it 

 more nearly resembles, as that is described with three thoracic 

 bands, the fore-wings with an ochraceous tinge, and the wings 

 [the four] with black marginal dots. In a pen-and-ink sketch 

 of the typical specimen in the British Museum, kindly sent 

 me by Mr. Butler, the marginal dots of the secondaries are 

 represented. C. Candida is the only species of the genus 

 which we have seen, in which these spots are absent from the 

 secondaries, and in which the wings are entirely white.
