diftuse and sproadinj;. Apical streak unusually lonji' and distinct. The three brandies of the 

 median vein are outlined distinctly in bniwn, and tliere is a faint sliadinj; of this color along 

 internal margin centrally. Hind wings very pale lititl'(U., V, l.'i), hut innch jialer. without dark 



shades; underside as hind wings above, the outer edge of 

 ])riniaries darker, w ith the fringe dark brown, as above. 

 Expanse of wings, 47-.V3 luni. 



A very distinct sjiecies with only one close ally, namely, 

 D. roIiKsfa Strecker. It dilfers from all the other species in 

 its bright yellow color. (I)yar.) 



-End. — ''In general sliajje subpyriform ; Hatteiied at base 

 and toi>, depressed centrally at \eitex, th(> usual black spot 

 small and indistinct, situated at the bottom of the ])uneti- 

 form depression ; the whole surface punctured. Color, white; 

 the lid like top of a somewhat brighter white. Ayidth, (t.O 

 mm.; height, O.S mm. The egg is of the typ(^ of that of JJ. 

 major, but rc^sembles that of I), niiiiisira in coloration, by 

 ])()ssessing a discolorous lid like toj). This is the i)art of the 

 shell eaten by the young larva in liatchiiig. Laid in masses 

 of varying numbers ou the underside of the leaves of the 

 food plant." (Dyar.) 



Litrcd, Stdfie I. — ''Length near the end of the stage, 

 about 'j mm. When first hatched the head is black, 0..") mm. wide: the body is yellowish, with a 

 reddish dorsal and subdorsal line, not reaching the extremities; 

 cervical shield, leet, and anal plate black. As the stage ad- 

 vances, the body becomes reddish, with lour lateral yellow 

 stripes on each side and three ventral, as in its allies, which 

 remain throughout the larval .stages. They are uearly as wide 

 as the intervening lateral spaces, a little ccniHuont ])osteriorly. 

 and are colored yellow." Llack hairs arise from small black 

 tubercles and from the elevated anal feet." (Dyar.) 



I, (lira, Sta(H' //.—"Head higher than wide, slightly i>unc- 

 tuied, black; width, 1.1 mm. Body i)arts colored as before. 

 The hair is short, blacki&li, and arises from minute tubercles 

 that are much smaller than in the previous stage." (Dyar.) 



Larra, tStfKjr J J I. — "Head shiny black, jnmctured, the cly- 

 l)eus smooth; width, l.fi-l.S mm. Cervical shield, anal plate, 



and thoracic feet black. Body dark red, the stripes broader than the intervening .spaces, bright 

 yellow; abdondnal feet red, the anal pair black. A few short hairs; sjiiracles small, black." (Duir.) 



The specimens described below Mere received Au- 

 gust 23, from Mr. James Angus, and so named by bim. 



Larva, Stafie III or IV''. — Length, 17 mm. The 

 head is black, not quite so wide as the body. A shining 

 black chitinous transversely oblong ju'othoracic shield. 

 The body is moderately hairy, the hairs reddish; it is 

 deep straw or lemon yellow, with eleven ])itchy reddish 

 lines; th^ median dorsal line is much broader than any 

 of the others and broadei' than the sjiiracular line; of 

 the two subdoisal lines, the upper is a little wider than 

 the lower; the lowest orinl'ias])iracular line is iiiterru]iled 

 by the sutures; tlie two ventral lines ol' tlu^ same reddish 

 coloi' pass along at and including the base <d" the thoracic 

 and abdominal legs. TIk^ suranal plate is small, shining black. The anal legs are ccmical, black, 

 excejit the reddish planta, which is distinctly eversihle, being seen at times to be retracted, 

 though armed with hooks. The two jiaranal ])lates are dark at the end; the end of the body is 

 constantly upheld. The thoracic and abdominal leus are black.
