ART. 19. MOTHS OF THE GENUS DIATEAEA DYAR AND HEINRICH 33 



hooked (uncus and gnathos in profile resembling a pair of short 

 nipper jaws). Anellus semitubular and without lateral arms; no 

 detached juxta. 



Female genitalia with ductus bursae moderately long, chitinized 

 only toward genital opening. Bursa copulatrix moderately large; 

 normally with two signa, rarely with single signum {discalis). Sup- 

 porting rods of ovipositor markedly dilated. Collar of eighth seg- 

 ment fused and with tongue projecting from anterior ventral margin 

 and curving back behind genital opening. 



Abdomen of male without tufts on second segment. 



The genitalic characters given above at once distinguish Haim- 

 bacMa from all other genera in the group with vein 11 of forewing: 

 anastomosing with 12; but many of the characters are duplicated in 

 genera of other groups, the chitinous tongue from a fused collar 

 of the eighth segment to the genital opening occurring in Xubidaj 

 Eoreuiiia^ and CMlo (examples, loftini Dyar and forbeseJlus Fer- 

 nald), and the dilated ovipositor rods and characteristically shaped 

 vinculum in Eoreumo) densellus and Chilo loftini. However, in both 

 Eareuma and Chilo^ where the vinculum is like that of Haimhachia, 

 there is much more marked asymmetry in the harpe than occurs in 

 any species of Hairnbachia. One species (prosenes) which we have 

 referred here does not exhibit any of the female genitalia characters 

 characteristic of the genus. It probably needs a new generic desig- 

 nation ; but as we have no male, and as it otherwise agrees with 

 Hainihachia, we have been compelled to i^lace it there.
