Sept. 1900.] KuNZE : Ova and Larva of Hvperchiria Pawina. 203 



Size of tubercles gradually tapers less toward abdominal segments. 

 At the base of subdorsal and infraspiracular tubercles the spines are 

 white and in bunches. Each segment from the first and including 

 eleventh has six spinulated tubercles. Those of first are not quite so 

 long as on second segment, but longer than any other. Head retracts 

 into first segment. There are five tubercles on twelfth segment, and 

 the dorsal ones longer than on any other joint. On the thirteenth 

 segment are five spinulated tubercles, of which four in a row and the 

 fifth placed behind the two dorsal ones on anal plate. Dorsal tuber- 

 cles of same length as of twelfth segment. Thoracic legs black, feet 

 brown. Prolegs reddish-brown, clasping surface covered by white 

 hair. A longitudinal, reddish-brown stripe, enclosing a white line, 

 passes centrally over entire abdominal surface. 



I remained only one week in Prescott, and took three of the larvoe 

 to Phoenix, for further observation, but all were dead by August i8th, 

 when supply of oak gave out. I removed a small bush to Phcenix, 

 planted in a shady spot, but it refused to live under all circumstances. 

 My other larvte of the same brood I left in Prescott, and these were 

 fed up to transformation on Querciis undiilata. 



Observed that the tubercles of supra- and infraspiracular row were 

 black, and that all spinules therefrom were white, with a white seta at 

 the end. Of the dorsal rows of tubercles, the white spinules occupied 

 the lower third of each tubercle. Could not distinguish spiracles with 

 a magnifier. A triangular depression above the face, the apex of 

 which meets the vertical line of forehead. 



Sept. 9, 1898, received two nearly full-grown larvce from Prescott 

 for observation. Length of larva at rest 38 mm. Width 7 mm. 

 Body of larva cylindrical. Head shining black, with median suture. 

 A triangular depression on clypeus. Mouth parts blackish. Antennae 

 brownish. A few scattering hairs on lower part of face. Width of 

 head 3^2 mm. Anterior part of 2d segment sooty, posterior half 

 white with blackish patch in the middle. Between the subdorsal row 

 of spines, a shining black ridge, with spur between dorsal and sub- 

 dorsal bunch of spines. Ground color of the dorsal surface from seg- 

 ments 3-13, white, relieved by six longitudinal, broken black lines. 

 The dorsal lines farther apart than subdorsal. Li the middle of each 

 segment back of the shaft of spines, are five transverse black dashes. 

 Two of the central dashes are in a continuous broken line with the 

 dorsal black lines. On segment 13, these transverse dashes are very
