advantage of a south, south-east or south-west wind upon which to travel. 

 If, then, they leave their hatching ground in the far south with a south- 

 west wind, they would be carried far to the east before reaching their 

 northern limit. Likewise, when the second brood was ready to fly south, 

 if the prevailing winds should come from the north-west, the hordes would 

 be swept over Nebraska, Kansas, etc., and into Texas. A continuous 

 south-west wind the next spring would take the spring brood still farther 

 east, while, on the other hand, south-east winds would carry them back 

 toward the plains. 



As the C. spretus always leaves its hatching grounds without depositing 

 eggs, Entomologists have jumped to the conclusion that broods raised on 

 the plains are barren or incapable of producing young • but the fact is 

 that they are not ready to deposit until two or three weeks after getting 

 their wings, which time they invariably take advantage of to remove 

 themselves several hundred miles from their place of birth. 



NEW NOCTUIDAE. 



UY LEON F. HARVEY, M. D., BUFFALO, N. Y. 



Errata. — In my article in the last number, Tricopis akncis should 

 read Tricopis aleucis. 



Tarache lactipenuis, n. s. 



Allied to cretata, but very much larger. Head, thorax and a narrow 

 oblique basal patch deep brown. A metallic tuft on the thorax behind. 

 Fore wings milk white. A subterminal broad, deep, olive shade from 

 apices to internal margin, containing a narrow, dentate, lilac-white line. 

 A greenish costal spot at about apical third. Terminal space whitish, with 

 a terminal dark shade line. Hind wings and abdomen white, the former 

 with a very slight fuscous edging. Beneath primaries wholly dark, except 

 along internal margin; hind wings wholly white. Expanse 28 m. m. 

 Habitat Texas (G. W. Belfrage, May 3, No. in.) 



Differs from Tarache metaUica at once by the white secondaries and 

 abdomen, as well as the absence of costal basal marks and the dentate
