Guide to the study of insects and a treatise on those injurious and beneficial to crops, for the use of colleges, farm-schools, and agriculturists . sh, witha reddish brown head,and having reddish pro-thoracic and anal feeds on straw andcorn, and Mr. Riley hasfound it feeding on Clover worm,or Asopia costalis 251. (^Fig, 251 ; 1, 2, larva in different positions; 3, 7, cocoon; 4, pupa; 5, 6, moth), ac-cording to Riley, attacks and spoils clover for feeding pur-poses, both in the stack and mow, by interweaving andcovering it with abundant white silken webs and black excre-ment that much resembles coarse gunpowder. The parent ofthese clover worms is a pretty little lilac-colored moth, withwide golden fringes, and has been introduced from moths fly late in June and in July, and they creep into allparts of the stack, as the larvae have been found eight feet fromthe ground, though they are mostly found at the bottom. Thelarva is three-fourths of an inch long and is dull dark brown,with an olivaceous hue. Mr. Riley thinks there are severalbroods through the year, and suggests as a preventative to. PYRALID^. 329 Stack the clover on a good log or rail foundation so as to allowthe air to pass up through from beneath. In Aglossa pinguinalis Harris, the Grease moth, the palpi arerather long, the fore wings are grayish brown clouded with adarker hue, and are crossed by two indented lines. The larvais of an uniform dark brown, with a darker head and protho-racic plate, and feeds on greasy horse clothes, etc. Another species of Aglossa (perhaps A. cuprealis) has beensent me by Prof. A. E. Verrill, who writes me that the larva doesgreat damage to the old leather bound volumes in the libraryof Yale College, by eating out great patches and galleries inthe leather covers, and also, in some cases, some of the glueand pasteboard. It spins a silken cocoon. The moth (Plate 8,fig. 20) differs from A. pinguinalis by the hind wings beingpale whitish
