American Army-worm. (Leucania unipuncta (Haw.) ; Flint, in

This destructive insect was recorded by Jones as common in 1876, 

 but I do not know whether it has ever proved so destructive to 

 grass and cereal crops as it often does in the United States. Miss 

 Victoria Hay ward states that a laiwa, locally called " Army- worm," 

 is very injurious to the common potato some seasons, but its iden- 

 tity is uncertain. 



The larva of L. unipuncta is dark gray, with three narrow, yel- 

 lowish dorsal stripes, and a wider darker yellow one on each side ; 

 head brownish yellow, lined with brown, and with a Y-shaped black 

 mark on the front. Length, about 1.5 inches. 



The moth has the fore wings dull russet-drab or fawn-color, with 

 a small, distinct, white spot in the center, and a dusky oblique stripe 

 at the tips, the surface sprinkled with black dots, two very small 

 pale yellowish dots near the white spot ; hind wings smoky brown, 

 translucent. Expanse, 1.75 inches. Canada to Colorado ; Florida ; 

 Mexico ; and South America. 



Leucania antica Walker was also recorded by Butler, 1884, as the 

 commonest moth in the Challenger Expedition collections. It is a 

 West American species according to Walker. The larvae are per- 

 haps among those called " Army-worms " in Bermuda. We should 

 expect that the southern Army-worm of the United States (Lap/i>/>/- 

 ma frugiperda) would also be found here, but it has not been 

 recorded.
