of mucli the same general appearance, but smaller and of 

 a more robust appearance. It feeds upon a great variety 

 of stored products as well as grain, but rarely becomes 

 troublesome. 



The Cadelle (Tenehroides mauritcmicns Linn.) (Fig. 00) 

 rJso has the bad habit of first attacking the embryo or 

 germ of the kernel, and going from one kernel to another, 

 thus destroying a large number for seed purjooses. It 

 possesses, however, the good trait of destroying other 

 injurious grain-insects. The beetle is oblong, flat, nearly 

 black, and about one-third of an inch long. The larva is 

 of a whitish color, with brown head, the thoracic segments 

 marked with brown, and the abdomen terminating in two 

 dark horny processes. It is a long fleshy grub, nearly 

 three-fourths of an inch long when full-grown. 



Flour- and Meal-moths. 



The larvae of several small moths sometimes infest grain 

 in store, but rarely do it serious damage, preferring the 

 softer flour, meal, and food-products. 



The most destructive of these is the Mediterranean Flour- 

 moth [Ephedia Jctieliniella Zell.) (Fig. 91). This insect 

 was jDractically unknown until 1877, but during recent 

 years it has occasioned the loss of many thousands of 

 dollars to mill-owners. It occurs throughout Europe, and 

 is found in Mexico and Chili. It was first recognized in 

 America in 1889, and has since done an increasing amount 

 of damage in California, in New York and Pennsylvania, 

 while it has been reported as occurring in North Carolina, 

 Alabama, New Mexico, and Colorado, and seems to be 

 constantly spreading. " The caterpillars form cylindrical 

 silken tubes in which they feed, and it is in great part
