NocTUA CuDicuLABiBS.—The larvae of these moths are small caterpillars, which have been found very injurious to the wheat crop in England, by eat- ing the grain before and after it is npe. It is figured and described by Mr. J<Min Curtis, in the Journal of the Koyal Agricultural Society of England. They also exist in North America and are known by the names, roheat-worm, gray-worm, and brown-weevil. The name of grain-worms'has likewise been applied to them, hence, they may have sometimes been confounded with the larvae of the wheat-midge, C'idkl<ami/ta Tritici; they are, however, completely distinct, and do not belong to the same order of insects. The larva is from three to five-eighths of an inch long, of a yellowish brown color, it has twelve legs, and ^' »e power of spinning and suspending itself by a thread. It feeds on the kernel in the milky state, and also devours the germinating end of the rip- ened grain. It is found in n;reat numbers in the chaff* when the grain is threshed. Unlike the maggots of the wheat-fly, with which they have been confounded, they remain flavouring the grain until after the time of harvest. They have been seen in «en«< numbers upon bam floors after the grain has been threshed, but they soon cruvvl away and conceal themselves in crannies where they most likely undergo their transformations. They are supposed by some to be identical with tiio clover-woi m. They may be distinguished from the maggot of the wheat-miuge ny rtieir brownish colour, being three-eighths of an inch in length, having legs, and capable of suspending themselves by a thread of their own s
