Tlianatopsyche thoracica Schaiis, Proc. U.S. Nat. Mus., vol. 29, p. 344, 1905 (new 

 synonymy). — Dalla Torre and Strand, Lep. Cat., pars 34, p. 184, 1929. —

Male. — (Fig. 43.) Antennal (fig. 385) pectinations gradually 

 decreasing in length before apex, biserrate in outer fourth. Body 

 vesture light brown to dark reddish brown. Foreleg (fig. 184) with 

 first tarsal segment over twice length of second. Metathoracic leg 

 with first segment of tarsus doubling second in length. 



Wings moderately and evenly scaled, ranging in color from light 

 brown to fuscous. Forewing with scales (fig. 349) of cell long, 

 slender, with narrow, rounded apices; venation relatively constant; 

 R3+4 invariably stalked; M2 and 3 stalked or connate. Hindwing with 

 basal crossvein sometimes absent; outer radial crossvein usually 

 beyond apex of discal cell; M2 and 3 as in forewing; outer margin 

 sinuate, curving slightly outward at middle. Wing expanse 25-47 

 mm. 



Male genitalia.^ — (Fig. 287.) Apex of tegumen consisting of 

 three evenly rounded lobes, median one very minutely clefted. 



Female. — Length approximately 35 mm. As described for genus. 



Female genitalia.— (Fig. 307.) 



Case. — (Figs. 95, 96.) Length 45-90 mm.; greatest diameter 

 7-12 mm. As described for subgenus. 



Types. — Lost {0. gerjeri and 0. tabacillus) ; in the United States 

 National Museum (0. jonesi and T. thoracica). 



Type locality. — Patagonia (0. geyeri) ; Argentina (0. tabacillus) ; 

 Sao Paulo, Brazil (0. jonesi); Omai, British Guiana (T. thoracica). 



Recorded hosts. — "Fabaceae: Acacia farnesiana Willd., Acacia 

 cavenia Hook, and Arn." (Berg, Anales, etc., 1877). "Cupres- 

 saceae, Junix>erus sp." (from specimen label). 



Distribution. — (Map 11.) Widely distributed; occurring from the 

 Volcanic Section of Central Mexico through the Central American 

 Ranges, southeast along the Guiana Coasts to French Guiana, and 

 south through much of the Amazon and Parana Paraguay Plains and 

 the Brazilian Highland. 



Discussion. — Oiketicus jonesi and Thanatopsyche thoracica are nothing 

 more than color variants of 0. geyeri. This and the slight variation 

 observed in the male genitalia are of no greater significance than that 

 present in any other species represented by an adequate series.
