PSYCHE. 



[June i900_ 



the last ecdj'sis were taken. These 

 closely resembled the adult in form and 

 ground color, ijut diflered in having no 

 red or roseate markings whatever. 

 Labrum marked as in adult, but anten- 

 nae green instead of pink; and each 

 segment margined with piceous. 



This species feeds largely upon 

 lamb's-quarter, Chenopodium album., 

 and furnishes an interesting example 

 of protective coloration, in that green 

 and roseate markings of plant and 

 insect are almost identical. The in- 

 sect, therefore, is not readily perceived 

 at rest upon this weed. 



Two males, three females (Ford 

 county) one male, two females (Ham- 

 ilton county) one female (Russell 

 county). 



Aeolopi.us. 



A. regalis Dodge. — The variation 

 among the specimens before us is very 

 slight, being limited to shades of color- 

 ation, and the markings of hind femora. 



They conform with Scuddei's descrip- 

 tion. The range of coloration was 

 noticeable, the green varying from 

 light to dark gi'een. One exceedingly 

 light colored female had doubtless been 

 taken soon after last moult. The 

 ground color varies from testaceous to 

 greenish yellow. 



Of the femur Scudder sa3's " testace- 

 ous yellow with two broad angulate 

 and sagittate bands darkest above;" our 

 specimens present these features and in 

 addition a basal spot which sometimes 

 takes the form of a third oblique stripe. 

 In some these angular bands fuse so as 

 to cover almost the entire surface of 

 the femur. The pallid base of hind 

 tibiae mentioned by Scudder takes in 

 our specimens the form of a clearly 

 defined annulus. 



Fourteen males, four females (Ford 

 county) one female (Russell county). 

 July ; common both in pastures and 

 cultivated crops, a rather late species 

 being most abundant in Aug-ust.
