STREPSIPTERA. Gil 



the common Cockchafer, &quot;of which eighty bushels were gathered 

 up.&quot; 



The genus Phyllophaga, (Gr. phutton, a leaf; phago, to eat ; ) 

 includes several species, which are furnished with strong jaws 

 for cutting the leaves of plants. They are injurious both in the 

 larva and the perfect state ; in the former, eating the roots of 

 grass, &c., and in the latter, the tender leaves of fruit and other 

 trees. Formerly they were included in the genus Melolontha. 

 They are well known by the name of Horn Bugs, though their 

 more appropriate name is MAY BEETLES. 



17. PEA BUGS, Wheat Weevils, &c., Brucliida, (genus Bru- 

 chus, Gr. bronchos, a locust locust-like.) The Pea-bug, Bru- 

 chus, is a small hairy insect, gray and rather egg-shaped, which 

 deposits its eggs in the pea-pod in its early state, and in which 

 they are hatched. Multitudes of the larvae are destroyed in pre 

 paring green peas for the table. The Calandra granaria, or 

 Corn Weevil, of Europe, is a species that has been introduced 

 into this country from Europe, in samples of grain, to which it is 

 very hurtful. Linnaeus calls it Curculio granaria. 



18. BLISTER BEETLES, Cantharida, (Gr. Kantharis .) Among 

 these are the C. vesicatoria, (Lat. from vesica, a blister,) of a 

 beautiful changeable or metallic green color, about three-quarters 

 of an inch in length, and well known for its medical uses. In 

 Spain, Portugal, and Italy, these insects are abundant. Potato 

 vines and other plants are, in mid-summer, often infested by in 

 sects allied to the Spanish-flies. 



N. B. The above account includes all the families of Beetles 

 to which the Chart refers, though but a small part of the entire 

 number. 



SECOND ORDER. STREPSIPTERA, (Gr. UTQWCOS, streptos, twisted; 

 nTeQov, pteron, wing.) 



Thisorderof insects is named by Latreille, Rhipiptera, (Gr. fan- 

 wings.) They have the front wings replaced by a kind of twisted 

 halterers ; the posterior are large and folded like a fan. (Plate XV. 

 fig. 3.) The tarsi have from two to four articulations. The mouth 

 is armed with two slender acute jaws wide apart, and two pointed 

 palpi, or feelers. The order includes a limited number of insects, 

 arranged in the two genera Xenos, (Gr. a guest or stranger,) and 

 Stylops. (Gr. stulos, a stylos or graver ; dps, face.) The larvse 

 are vermiform, and have six feet. The pupse are inactive. 

 They are all small, mite-like creatures, the largest not being a
