REVISION OF THE OECOPHORIDAE — CLARKE 197 



6. APACHEA, new genus 



Plate 2, Figure 16 ; Plate G, Figure 40 ; Plate 13, Figukes 86, 86a, 86b ; 

 Plate 15, Figure 94 



Genotype. — Depi-essaria harherella Busck, Proc. U. S. Nat. Mus., 

 vol. 24, p. 747, 1902. 



Similar to Depressaria but with broadly triangular brush on second 

 segment of palpus, fused anellus and transtilla in the male genitalia 

 and with the signum of the female genitalia a distinct cross. 



Head with appressecl scales; side tufts spreading; tongue de- 

 veloped; antenna simple in both sexes; basal segment elongate, with 

 pecten. Labial palpus moderately long, recurved; third segment 

 nearly as long as second, acute; brush of second segment broadly 

 triangular, flared. Thorax with two small crests. Abdomen flat- 

 tened. Fore wing with 12 veins ; 2 and 3 closely approximate ; 7 and 

 8 stalked, 7 to costa; 11 from before middle. Hind wing broader 

 than fore wing; 8 veins; 3 and 4 short stalked, 5 separate from 4; 

 6 and 7 subparallel. 



Male genitalia. — Harpe with clasper. Anellus and transtilla fused. 

 Uncus distinctly wanting. Aedeagus armed. Gnathos a spined 

 knob. Socii wanting. 



Female genitalia. — Genital plate strongly sclerotized. Signum 

 present. 



Larva. — Ninth abdominal segment with setae I and H well sep- 

 arated ; setae VI on the same pinaculum with IV and V, remote from 

 VII. Setal group VII with multiple hairs (4 to 6) on abdominal 

 segments 2 to 7, trisetose on eighth and unisetose on ninth abdominal 

 segments. A few secondary hairs on anterior margin of prothoracic 

 shield and on anal prolegs. Ocelli normal. Submentum without pit. 



Pupa. — Pubescent. Prothoracic femora and labial palpi not 

 exposed. Cremaster absent. 



Remarks. — This genus is closely allied to both Depressaria and 

 Ago7ioptenx but appears to be a specialized offshoot from the 

 former. It can be distinguished readily from both by the fused anel- 

 lus and transtilla and armed aedeagus of male, the 4-pointed signum 

 of female, and the proximity of veins 2, 3, and 4 of fore wing. 



In the larval stage Apachea is distinguished from other genera of 

 American Oecophoridae by the presence of secondary hairs in setal 

 group VII, a character which otherwise distinguishes the family 

 Ethmiidae. The pupa is typically oecophorid with essentially the 

 same characters as the pupae of Agonopterix and HofmannopMla. 



The genotype is the only species I have seen referable to this genus.
