it in the act. The head is as witle as the 

 prothoracic and middle body-segments ; 

 the 3d thoracic and ist abdominal seg- 

 ments are by this time somewhat swol- 

 len. A distinct narrow white lateral line 

 is now present, while the dorsal region 

 between the two lines is paler than on 

 the sides of the body. The head is now 

 rough with small pointed tubercles. 

 There are no lateral oblique stripes 

 present. The caudal horn is reddish 

 flesh-colored, becoming darker at the 

 tip. 



Stage IV. Length 35 mm. Moulted 

 24 July. This I suppose to be the third 

 moult. The head is long, somewhat 

 k-ngthened towards the vertex, and 

 slightly flattened on the sides ; the sur- 

 face is unequally tuberculated with sharp 

 conical white tubercles arranged in irreg- 

 ular longitudinal lines. There is along 

 each side of the head a broad, yellowish 

 lateral stripe, and a faint yellowish shade 

 along each side of the median suture. 

 The yellowish line on the side of the 

 head is continued on the body as a sub- 

 dorsal whitish line, which is faint on the 

 prothoracic segment ; this lijie liehind 



the middle of the 3d thoracic is formed 

 of a row of rather large conical tuber- 

 cles, it again becomes continuously 

 white on the 7th and Sth abdominal seg- 

 ments, fading out at the base of the cau- 

 dal horn, which is whitish, with sharp, 

 slender black tubercles on the upper and 

 under side of the horn, the tubercles on 

 the sides being white ; the tip of the 

 horn is flesh-colored, and the entire horn 

 is nearl}' twice as long as the body is 

 thick. The spiracles are raw-sienna 

 brown, with a white spot at each end 

 of the respiratory slit above and below. 

 The thoracic legs are peculiarly spotted 

 with black on the green base, and are 

 reddish cherry at the ends. All the ab- 

 dominal legs are greenish. The body 

 is thickest on the 3d thoracic and ist 

 abdominal segment. On the 3d thoracic 

 to the 5th abdominal segment are faint 

 oblique lateral whitish stripes, bearing 

 white obliquely-arranged white tuber- 

 cles, those on the first three abdominal 

 segments more distinctly underlined by 

 white. It died 5 Aug., when nearly 

 full-fed. 



Note on two species of Datana. — 

 From my remarks after the two species 

 of Datana which I described, (Psyche, 

 V. 5, p. 299-300,) it might be inferred that 

 they were compared with a number of allied 

 species. I would like therefore to state that 

 Datiuia modesta was compared with the type 

 of D. floridaiia in the collection of Mr. 

 Edward L. Graef, and that D. palmii was 

 compared with a type of D. h/fcori-r/Dui G. 



& R., in the collection of the late Coleman 

 T. Robinson, now in the American museum 

 of natural history, N. Y.

 of lepidoptera in this country by the biblio-
