BULLETIX 363, V. S. DEPAKTMEXT OF AGEICULTUEE. 



spots on the sides of the apical joint. Antenns with white and fuscous annulations; 

 the basal joint elongate, chestnut brown. Fore-wings chestnut-brown, slightly 

 shaded with fuscous towards the costal margin; a whitish ochreous streak at the base of 

 the dorsal margin, followed by two or three other smaller ones along the dorsal margin 

 (in some specimens these are obsolete); above the dorsal margin are two oblique 

 whitish ochreous streaks, the first before the middle, the second before the anal 

 angle. A similar streak from the costal margin immediately before the apex is out- 

 wardly margined by a streak of black scales, the apex and apical margin being also 

 black; there is also a faint fuscous streak running downwards through the cilia below 

 the apex. On the cell are two elongate patches of black scales, one immediately 

 before the middle of the wing, the other halfway between tMs and the base. Fringes 

 grey, with a sUght yellowish tinge. Hind wings pale gre\dsh. Hind tibiae greyish 

 white, outwardly fuscous; hind tarsi whitish, with a wide fuscous band followed by 

 two fuscous spots on their outer sides. Expanse 11 millim.

THE EGG. 



The eggs of this species resemble considerably those of the Angou- 

 mois grain moth (Sitotroga cerealella) . They have been found 

 deposited on dry corn husks and in such locations are much flat- 

 tened on the surface, differing in this respect from those of Sitotroga. 

 The egg may be described as follows: 



Flattened oval; widest near the middle; truncate at one end and narrowed at the 

 other, with the surface strongly wrinkled, forming coarse, irregular, ridgelike longi- 

 tudinal Knes. As would naturally be expected in a species so much smaller than 

 the Angoumois moth the egg is much smaller, and instead of being red it is pearly 

 white thi'oughout with a perceptible iridescence. 



Measurement: Length, 0.4 mm.; width, 0.1 mm. 



The eggs are deposited singly or in groups up to three or four. 

 Since they are nearly colorless, not pinkish like those of the Angou- 

 mois moth, they are quite difficult to locate with the unaided eye. 

 The egg is illustrated by figures 3 and 4.
