BAGWORM MOTHS OF THE WESTERN HEMISPHERE 109 



Type. — In the Institute de Biologia, Mexico City. 



Type locality.— Zihuatanejo, Guerrero, Mexico. 



Recorded hosts. — "Fabaceae: Caesalpinia palmeri Wats. ; Bursera- 

 ceae: Bursera sp. (cuajiote)" (Vazquez, 1951). 



Distribution. — (Map 10.) Known only from Zihuatanejo, in the 

 Sierra del Sur Section of west central Mexico. 



Material examined. — 2 cf cf, 1 case: 



MEXICO: Guerrero: Zihuatanejo, 2 d'd', June IS, 29, case, (USNM). 

 Oiketicus, subgenus sensu stricto 



Type of subgenus. — Oiketicus kirhyi, Guilding, 1827. 



Male. — Antennal pectinations rather abruptly decreasing in length, 

 strongly biserrate outer half to Yz length. Prothoracic leg (fig. 185) 

 with tibia long, greater in length than tarsus; first tarsal segment 

 slightly longer than second, never doubling it in length; epiphysis 

 somewhat reduced, usually arising Yi distance from proximal end, 

 never reaching distal end of tibia, or epiphysis absent {0. platensis). 

 Mesothoracic tibia conspicuously longer than tarsus. Femur of 

 hindleg dilated. 



Wings usually with distinct pattern. Prunaries with discal ceU usually 

 completely filled with dark scales; outer margin of cell devoid of scales, 

 forming irregular hyaline bar; apical third or fourth of wing with dark 

 area of scales fanning out from cell; this area usually approaches cell in 

 color, extending from apex of cell to wing apex and from midway along 

 lower margin of cell to tornus; cell 2 A with dark patch of scaling; 

 remainder of forewing usually of a much lighter fuscous or brown color. 

 In some species (0. toumeyi and 0. assimilis) wing scales deciduous or 

 nearly so, but in some a faint pattern can be detected. Spurs from 2A 

 to hindmargin frequently present. Secondaries unicolorous, outer 

 margin various, often rather deeply excavate. 



Male genitalia. — Relatively long, slender as compared to Paraoi- 

 keticus. Saccus very long, sometimes equalling remainder of genitalia 

 in length. Aedeagus slender, neck region very elongate, abruptly 

 enlarging to bulbous base. 



Case. — Variously ornamented; never naked or smoothly cylindrical 

 as in Paraoiketicus. Exterior frequently covered by thatching of small 

 sticks, which may be covered by thin layer of silk; sometimes leaves 

 are only extraneous material incorporated into structure.
