THE GREEX JUNE BEETLE. 7 



forms of beetles. While the outer surface of this cocoon-like cell 

 is rough, the interior is smooth and suggestive of a bird's egg. 

 There is a protuberant area on one side, presumably on the lower 

 surface, which may be due to the excess of fluid voided by the larva 

 while constructing its cell. 



This cell measures about J inch or 16 mm. in length and f inch 

 or 12 mm. in width. 



THE PUPA. 



The pupa bears some resemblance to the adult or beetle and is 

 white when first formed, changing to light or yellowish brown, 

 afterwards becoming gradually darker, and just before emergence it 

 takes on some of the metallic green and brownish tints of the adult.

It measures about 1 inch in length and half an inch in width. Other 

 characters are shown in Plate III, B. 



DISTRIBUTION AND INJURIOUS OCCURRENCE. 



The green June beetle (Cotinis nitida) has a wide distribution 

 in the eastern portion of the United States. (Fig. 4.) On the 

 Atlantic coast it ranges from the southern portion of New York State 

 to Florida and Texas in the South, and it is found also in the southern 

 portions of Connecticut, Pennsylvania, Ohio. Indiana, and Illinois. 

 The species continues southward through Missouri, Kentucky, and 

 Oklahoma, and probably the remaining southern States, from which 

 source, however, there are few records available. 5 There is a single 



5 The nearest related snecies, C. mutatilis Gory, occurs abundantly in the arid and semi- 

 arid regions of the Southwest.
