THK AGRICULTURAL PESTS OF INDIA. 43 



Clothes Moths. See Tineidse. 



Coccidae. A family of Homopterous insects known as 

 scale-insects. See Coccus. 



Coccinella are known as the lady-bird or lady-cow. 

 In the larval and mature stages they are said to feed 

 exclusively on the injurious parasites on plants of the 

 aphides or plant-lice ; but, in Bengal, a twelve-spotted 

 species undoubtedly feeds on the leaves and flower-buds 

 of nearly all the Cucurbitaceee. J. Scott. See Coleoptera. 



Coccus adonidum, in the hot-houses of Europe, often 

 commits great injury. See Lecanium ; Pseudococcus. 



Cockroach. This name is given to the Periplaneta 

 orientalis, and the American P. americana. Also to species 

 of the genera Blatta, Blabera. Panchlora, Phoraspis. 

 They destroy the young shoots and flower stem of orchids. 

 They soil and injure books and clothes, and are peculiarly 

 troublesome in ships. They shun the light. 



Cocoa-nut palm. Cocoa-nut trees have great enemies 

 in the shape of two beetles. One of these is a large 

 Curculio (Ehynchophorus, Sack.), called the red beetle, 

 nearly as big as the stag-beetle of Britain ; the other is 

 the Oryctes rhinoceros, so called from its projecting horn. 

 The red beetle is so called from the red mark on the 

 upper part of its breast. Its attacks are said to be on 

 the nut, but those of the rhinoceros beetle are on the 

 terminal bud of the palm stem. When so injured, the 

 bud dies, and, the crown of the leaves falling off, leaves 

 the cocoa-nut tree a mere bare stem. The same result 

 occurs to other palms, as the palmyra, the betel, etc., 

 in which the top bud, or cabbage as it is called, is 

 destroyed. 



Coffee trees have been injured by many insects and 

 plants. Mr. K. C. Haldane, in 1 8 8 1 , in his book, 'All about
