320 MEAL MOTH — WHERE FOUND. 



The yellow larva? first spoken of are about as numerous as the green ones, and 

 acquire a pale obscure red color, dusted over with a fine whitish powder. They 

 change to pup^:, which are known by having a scale on each side of the body, which 

 is the sheath in which the future wing is enveloped at this period. These scales 

 are pale yellowish, their tips dusky. The pupa? are 0.06 in length, dull red and 

 dusted over with a glancous powder, oval and less plump and convex above than 

 when they were in the larva state; their heads are dusky, antenna? obscure yellow 

 with dusky tips reaching to the base of the wing scales, legs dusky, the thighs except 

 at their tips, and also the anterior shanks obscure pallid. 



The winged females which come from these pupa? are scarcely 0.06 in length, 

 and to the tips of their wings 0.10. They are black, the abdomen dull lurid green, 

 with black punctures and dots along each side, and three black bands at the tip, 

 and opposite these on the under side a transverse black spot. The nectaries, legs 

 and antenna? are similar to those of the wingless female. 



AFFECTING THE STORED GRAIN AND MEAL. 



In stale Indian meal and eniptying-cakes made thereof; a soft white worm 

 half an inch long, with a brownish yellow head and polished yellowish 

 white spot above on the neck, and on the last segment. 



The Indian meal moth, Tinea Zeee, new species (Plate 4, fig. 1). 



Our housewives are sometimes vexed with finding their 

 store of emptying cakes, which are used for exciting fermenta- 

 tion in dough, invaded and spoiled by worms. If the bag or 

 box in which these cakes are kept happens at any time to be 

 left open, the winged moths from which these worms proceed 

 are liable to find their way into it, and scatter their eggs through 

 the cakes, so that the whole of them are at a subsequent day 

 discovered to be infested with worms. As Indian. meal is the 

 chief ingredient in these cakes, I infer that to be the favorite 

 food of this insect, and that it might therefore exclaim, with the 

 enraptured Barlow in his Hasty-pudding, 



"All my bones were made of Indian corn — 

 Delicious grain !" 



More particularly where the meal of maize has been long kept 

 and has become stale, I suspect this insect will be apt to infest 

 it. But it is only in the situation first spoken of that I have as 

 yet met with it. 



The worms appear to have the same habits with the larva of the 

 grain moth or the wolf, Tinea granella. They form cylindrical 

 burrows through the substance on which they feed, lining the
