whose color is orange red, marked with black and white, is said to have 

 been of immense service in checking the ravages of the Colorado beetle 

 in some ot the Western States. The larvae of all these species are very 

 fierce, and feed on both the eggs and young larva? of both the Colorado 

 and three-lined potato beetle. 



'The next insect belongs to the order Hemiptera (half- 

 wings), the true bug family. It is the rapacious Soldier 

 Bug Red m 7 its raptatorius ( Say ) — See fig. 21. Its color is' 

 light brown, and it attacks the larvae only cf the Colorado 



beetle. 



We have detected another insect friend belonging to this 

 family in the act of extracting the juices from the body of 

 a young Colorado larva, into which it had thrust the long rostrum, or beak, 

 with which all the members of the family are furnished. Its name has not 

 vet been determined by us. 



The next two friendly insects are known as Carabidce, or Carniverous 

 ( Jround Beetles. 



FIG. 22. 



Colors — Black, with cop 

 pery dots.

Color— Dull black. 



CaJosoma calidum (Fabr. ) — The glowing calosoma 

 (see fig. 22) is so called from the appearance of its 

 wing-cases, which are shining black, with six rows 

 of sunken coppery spots. This beetle is easily found 

 under stones or logs, in moist weather, in May and 

 June. It is exceedingly active in its movements, and 

 a valuable friend to the agriculturist. 



The murky ground beetle, Harpalus caliginosus 

 (Say) — see fig. 23— is the last one on our list. It is 

 of a dull black color, and may be readily recognized 

 from the drawing. All the insects belonging to this 

 family are carnivorous in their habits, and we shall 

 doubtless find among them some other species at- 

 tacking the Colorado Potato Beetle. 



In some of the figures we have used, the insects 

 have been enlarged, and in such cases the correct 

 size is represented by a hair line at the side of the 

 drawing. 



POULTRY, 



There is a great diversity of opinion as to whether 

 poultry will, or will not, eat the larva* of the potato
