350 NORTH AMERICAX CALLDIOKPHA. 



{Mentha viridis). Lenrjth at rnntinity 1 iiu-h; tuberculated, bearing fas- 

 cicles of stiif hairs; dark brown with yellow spots. It made a cocoon 

 just beneath the surface of the ground July 1; from which the moths 

 emerged July 24." 



^yhich of the forms these imagos were is not stated, though it waS' 

 probably the i)resent species.

Head pale yellow, as are also the pali)i ; antennre pale brown. 

 Thorax white, rarely with a faint trace of a dorsal line anteriorly. 

 Abdomen white, basal segment often yellowish above. Prinmries 

 silky-white, immaculate, save for a very faint fulvous or yellowish 

 shade along the costa. Secondaries immaculate. Beneath white, im- 

 maculate. 



Expands 1.80-2 inches =47-50'^"". 



Habitat. — New York, Texas, Missouri, and Illinois. 



This has been said to be an immaculate variety of lecontei, and, indeed^ 

 it may be, but I do not believe it. I have never seen any specimen 

 w^hich in any Avay was doubtful, and have never seen anything like a 

 series of intergrades between this and lecontei. The almost immaculate 

 form mentioned under suffusa was evidently a form of that species, 

 because the thoracic band was well marked, the wings have not that 

 shiny appearance peculiar to the present form, and the habitus, which 

 is so ditilicult to describe, but so readily seen by the trained eye, at once 

 bespeaks a different species. It would need positive proof by breeding 

 to convince me of the specific identity of these forms. I have not been 

 able to dissect a male of this form. 



The larva has been described by Professor Kiley in his Third Eeport, p. 

 134, as follows : " Color velvety -black above, pale bluish-gray sprinkled 

 with black below ; a deep orange medio-dorsal line (usually- obsolete 

 towards each end) and a more distinct, wavy, broken, yellow stigma- 

 tal line, with a less distinct, coincident pale line below it. Covered with 

 large, highly polished, roughened, deep steel-blue warts, the irregular- 

 ities of w'liich, as they catch and reflect the light, look like i)a1e blue 

 diamonds. Closely examined these warts are found to be covered with 

 small elevations, each of which furnishes a short, stiff yellow hair, tiiese 

 hairs radiating in all directions around the warts which are i)laced as 

 follows: Joint 1, with an anterior transverse row of eight, and a jws- 

 terior dorsal row of four; Joints 2 and 3 each with a transverse row^ of 

 eight across the middle; joints 4-11, inclusive, each with four circular 

 ones anteriorly, and two irregular ones posteriorly on doisum (each of 

 the last evidently formed by the blending of two), and two on each side 

 near the middle of the joint; joint 12 with two that are irregular on the 

 back, and one that is circular on each side. Anal shield formed of one
