Specimens are before me from Grenada, Trinidad and the 

 Guianas. Hampson gives also Brazil, but Brazilian specimens 

 before me are separable specifically. The species feeds on 

 sugar cane in the larval state, as proved by a bred specimen 

 from Mr. F. W. Urich. 



</ Diatraea amnemonella, new species. 



Similar to canclla Hamps., but narrower-winged, the markings more 

 diffused and obscured. The female is gray, like the male, while the 

 hind wings are white in both sexes. The frontal prominence is a 

 central cone, not a plate. 



Male and female, Castro, Parana, Brazil (Schaus collection). 

 Type, No. 13618, U. S. National Museum. 



Diatraea zeacolella, new species. 



Female with the wings broad, the apex square ; color straw yellow, 

 the brown lines on the veins conspicuous, generally more so than the 

 lines between the veins; no bands of dots, or only slight traces of 

 them; terminal dots larger than in saccJiaralis, but yet small, generally 

 present; discal dot black, present. 



Male generally larger and somewhat broader winged than sac- 

 charalis, the same specific differences present as in the female, but in 

 lesser degree ; the two bands of dots are present, but are not intensi- 

 fied by dark shades ; the linings on the veins are more contracted than 

 in saccharalis. 



Types, five males and nine females, Tryon, North Carolina, 

 April 4, June 2, August 2 and 9, 1904 (W. F. Fiske) ; Xinety- 

 six Post Office, South Carolina, larvae received July, 1880, 

 issued May 9, 1881 (W. L. Anderson) ; Fredericksburg, Vir- 

 ginia, issued July 26, 1890 (Dept. Agr., No. 1015?) ; Alexan- 

 dria County, Virginia, larvae in Thripsacitui dactyloidcs July 

 15, 1891, adults issued August 13 and 21, 1891 (T. Pergande). 



Type, No. 13556, U. S. National Museum. 



The figures published by Dr. Howard of the "larger corn- 

 stalk borer." (Insect Life, iv, 95, 1891) represent D. zeacolella. 



This species is transitional toward the next group, the males 

 having the markings of the saccliarolis group, whereas the 

 females considerably resemble lineolata Walker.
