Figure 2, Male. 



variety of the males is reported to have made 

 its appearance. In both sexes there is a dash 

 of bhvck at the apex of the front or primary 

 wings, a bhick spot near the outer margin of 

 the same, about midway between tlie costal or 

 front and the inner or back margins, a similar 

 spot on the front margin of the posterior wings, 

 ■while the female (sec Fig. 1) has a second spot 

 on the primary -wings near the posterior border,

both sexes having two spots on the prima- , 

 ries, corresponding in position to tliose on 

 the upper surface of the same in the females. 

 The Avings beneath are also tinted with j^el- 

 low, especially near the tips, which feature 

 is important, as in rare cases the spots are so 

 obscure, or so entirely absent, that the yellow 

 tint becomes of much importance in deter- 

 mining the species. 



The eggs are laid either singly or in clusters of two or three beneath the 

 cabbage leaves. They are so small as to easily escape notice, but under the 

 microscope are observed to be beautifully marked. They are white at first, but 

 soon turn yellow. 



The caterpillar (see fig. 3, ft) is of a i)ale green color, finely 

 sprinkled witli black, with a yellow stripe along the back and 

 a more obscure one along each side. When fully developed it is 

 over one inch long. 



Tlie chrysalis (see fig. 3, &), which will be found under a clod, 

 board, fence-rail, etc., — Mrs. Bessie Strong of Fairfield, Lena- 

 wee county, writes mo that she found many on the cabbage 

 leaves, — is of the usual form of papilionacious chrysalids, and 

 '^, is suspended not only by the tail, but also has a fine silken cord 



I thrown around its shoulders, ilow the caterpillar can accom- 



plish this feat, — spin the cords, make the attachments, and then 

 i .^gct out of its skin, — is a marvel which would cause even a phi-

 a, larva, 6, chrysalis, jt. It, witli tliousaiicis morc equally wonderful exhibitions, are 

 being enacted every summer's day all about us. Is it not possible tliat were 

 our children taught to observe these startling performances of nature, the less 

 astonishinsj feats of circus clown and acrobat would lose something of their 

 attraction, while the saloons would entrap fewer of those just ripe to be en- 

 snared? I tell you, gentlemen, it is not only possible, but certain. The color 

 of the chrysalid is green, sprinkled with small black dots. 



Thus I have daguerreotyped this evil doer, and T urge each and every gardener 

 to constitute himself a detective and secure the picture that he may be ready 

 to recognize and repulse tiiese arch destroyers at the first onset. 



NATURAL HISTORY. 



The imported cabbage butterlly, like both our native species, is two-brooded.
