stack the clover on a good log or rail foundation so as to allow 

 the air to pass up through from beneath. 



In Aglossa ping uinal is Harris, the Grease moth, the palpi are 

 rather long, the fore wings are grayish brown clouded with a 

 darlver hue, and are crossed by two indented lines. The larva 

 is 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 been 

 sent me by Prof. A. E. Verrill, who writes me that the larva does 

 great damage to the old leather bound volumes in the library 

 of Yale College, by eating out great patches and galleries in 

 the leather covers, and also, in some cases, some of the glue 

 and pasteboard. It spins a silken cocoon. The moth (Plate <s, 

 fig. 20) differs from A. pinguinalis by the hind wings benig 

 pale whitish gray, instead of grayish brown. The palpi have 

 the third joint one-third as long as the second. It is pale 

 brown, with a slight reddish 

 tinge, and the wings are 

 crossed by two pale bands, 

 with several pale costal 

 spots. The outer band is 

 heaviest on the costa and 

 inner angle, and faint in 

 the middle of the wing. The hind wings are pale, shining 

 whitish, with no bands. It expands .90 of an inch. 



In Europe, Mr. Curtis states, the Aphomia colonella Linn. 

 (Fig. 252) which also occurs with us, is a formidable foe of the 

 humble bee, feeding upon its honey. AVhen fully fed it spins a 

 tough Aveb of a close wooU}' texture, in which the caterpillar 

 turns to a chrysalis («). "The female moth creeps into the 

 nest in June to deposit her eggs, and the caterpillars live in 

 families sometimes of five hundred, to the total destruction of 

 the progeny of the poor humble bees. The moths are of a dirty 

 white, the upper wings have a greenish and rosy tinge, with a 

 line of black dots round the margin, a whitish space near the 

 base, and two black lines near the costa in the male. The fe- 

 male has two distinct, indented, transverse bars, and two black 

 spots on the disc."
