The Virginian Tiger-beetle.— 

 This beetle (Teirachtt, Virglnlcan 

 Hope) is of a dark metallic green 

 color, with brown legs, and the an- 

 nexed cut (Fig. 59) will enable its 

 recognition witliout much difficulty. 

 Toe Fiery Ground ■- beetle.— 

 This beetle ( Qalosoma calidum., 

 Fabr.) has already been treated of 

 on page 89 where its larva is illus- 

 trated and termed the u Cut-worm lion.-' The beetle is of a black 

 color, with coppery dots, as shown in Fig-are 60, and has also been 

 found to prey on the Colorado larva. 



[Fig, n.i The Elongate Ground-beetle.— 



This pretty and conspicuous insect 

 (JPasimac\us elongatus, Leo.) is an* 

 •other enemy of the .'Colorado Pota- 

 to-beetle. It is of a polished black 

 color ed^ed with, deep blue, and is 

 of a rather elegant form, being re- 

 presented at Fig-ure 61. 



The Murky Ground beetle.— 

 Finally this beetle (Earpaluscali- 

 :ji?iosus, Say) which is of a dull black color, and which is represented 

 life-size at Figure 62, has the same commendable habit as the other 

 ■three. There are ten or twelve other beetles mostly of small size, 

 which have the same habits as the above ; but they would not be 

 Teadily identified from an uncolored drawing. 



Blister Beetles.— Strange as it may seem, the Striped Blister- 

 beetle (Fig. 39, p. 97), and the Ash gray Blister-beetle (Fig. 40, <&, p. 98), 

 "which have already been described as very injurious to the potato, 

 seem to have the redeeming trait of also preying occasionally on the 

 larva of the Colorado Potato-beetle. It was at first difficult to believe 

 or reconcile the statements to this effect which were reported during 

 the summer, but there have been so many of them that the fact may 

 •now be considered as indisputable, and these two Blister beetles may 

 therefore, with propriety, be placed in the list of the enemies of the 

 Colorado beetle. I by no means advise their protection, however, on 

 this account", tor I believe that what little good they accomplish is 

 much more than outweighed by the injury they do us. As authorities 

 for these statements may be quoted, among many others, Abel Proc- 

 tor, of Jo Daviess county, 111., and T. D. Plumb, of Madison, Wis., 



'"•'When dog cats ■dog, then comes the tug of war^" 



when rogues fall out, honest men come by their own. And now that 

 certain potato-beetles have taken to feeding upon other potato-beetles, 

 fiie American farmer may justly lift up his voice and shout for joy. 



Neither ducks, geese, turkeys nor barn-door fowls will touch the 

 Sarva of the Colorado-beetle when it is offered to them; and there are
