eties may prove to be valid species when their history is known, as, for 

 instance, C. coiitigua, which is stated by the editor of the Canadian En- 

 tomologist, (vol. I, p. 45,) to be quite a constant form. For convenience 

 of reference, the following references to the markings of the different 

 varieties are added : 



C. contigua, Walker, "Primaries brow^n, with a white discal stripe 

 which widens from the base to a little beyond the middle, and with two 

 large subapical white spots. Secondaries with a small brown spot near 

 the hind border." 



C. confinis, Walker, "Primaries brown, with a discal, slightly angu- 

 lar white stripe, and an elongate triangular oblique subapical white 

 band." 



C. fulvicosta, Clemens, of which C. vestalis, Packard, is only a syno- 

 nym, ' ' White, palpi orange yellow, tips blackish. Head, prothorax 

 and anterior edge of fore wings, especially beneath, orange yellow. 

 Sometimes the costa of the fore wings is dark brownish. Breast and 

 legs orange yellow, the middle of fore tibiae and tarsi blackish. Abdo- 

 men tipped with yellowish orange." 



Larva; C. Lecontei. — Mr. Saunders succeeded in rearing four speci- 

 mens, which he states resembled each other very closely, but does not 

 give the name of the variety produced. The larvae were found June 10, 

 feeding on horse gentian, (Triosteum perfoliatiim); they entered the 

 chrysalis state June 19-20, and produced the imago July 12-14. The 

 following is his description of the larva : 



"Length i.io inches, nearly cylindrical. Head rather small, bi- 

 lobed, black and shining, with a few short hairs, mandibles black, palpi 

 pale brown tipped with black. 



"Body above black, with transverse rows of elevated shining black 

 tubercles, from each of which arises a spreading tuft of short bristly 

 hairs, a bright yellow dorsal stripe, and a wide band of the same color 

 on each side, this latter intersected with streaks and centered with a 

 broken band of black ; about half way between the dorsal and lateral 

 stripes, is a row of pale whitish dots, forming a faint broken line. 



"Under surface dirty greyish white, with streaks and dots of brown, 

 feet black, prolegs dirty white on inside, with a patch of shining black 

 on the outside of each." Canadiafi Entomologist, vol. i, p. 20.
