BUTTERFLIES HERRERA AND FIELD 477 



anterior free angles greatly produced and with ventral margin un- 

 dulate. Ductus bursae with ribbonlike plate large, fused to anterior 

 subtriangular plate and with a pair or more of small irregularly shaped 

 plates anterior to this. As in the male, no differences are displayed 

 between the three subspecies. The genitalia of six females were 

 studied. 



Seasonal variation: In the spring and sometimes in the fall, this 

 Chilean species produces a form that is smaller (cf, 19-25 mm., 

 average 22.6 mm.; 9, 22-24 mm., average 22.8 mm.) with all markings 

 correspondingly reduced in size (pi. 1, figs. 4, 4a). 



Type locality: Herewith restricted to central Chile. A mLxup 

 over the type locality is the reason for the restriction. Boisduval, in 

 his original description, cited the type locality as "Bourou" (Burn, 

 an island in Indonesia). Later, he (1836) corrected this to Payta, 

 Peru. However, this locahty is also in error as no species found in 

 Peru fits either the original description or his subsequent description, 

 while the species here discussed from central Chile and southward 

 does agree with his descriptions. 



Additional type data and location of types: T. theocHce was 

 originally described from the female sex, the number of specimens 

 not being given. The type should have gone to the British Museum 

 from the Oberthiir collection. Mr. D. S. Fletcher of that museum 

 writes that the type is not in the collection there. He states further 

 that there is a Boisduval specimen labeled "type" by some subse- 

 quent worker but that it is certainly not the t^^pe, "for even if Bois- 

 duval were to mistake his sexes" (the specimen in question is a male) 

 he would never mistake pure white for "white, a little yellowish." 

 Mr. Jean Bourgogne of the Paris Museum searched the collections 

 there and reported that the type of theodice is not present. The type 

 is apparently lost. 



Method of identification : Based upon the original and subse- 

 quent descriptions of Boisduval which positively fix the name theodice 

 to the species here described. A neotype designation is not needed. 



Synonymical notes: The data for the names listed in the above 

 synonymy are as follows: 



Pieris demodice Blanchard, 1852, Type localitj-, "Provincias del Norte,'' 

 Chile (this should be interpreted as the north-central provinces, south of Anto- 

 fagasta). Described from an unspecified number of specimens of both sexes. 

 There are one male and three females, cotypes, in the Paris Museum. A lectotype 

 is not designated. The original description can apply only to T. theodice. 



Tatochila theodice flammivolans Bryk, 1944. Type locality, "Peninsula Llao Llao" 

 on Lago Nahuel Huapf, Territory of Rio Negro, Argentina. Described from 

 holotype male, allotype female, and 20 male and 5 female paratypes. Type in 

 Naturhistoriska Riksmuseet, Stockholm. Specimens from Villa Angostura and 

 Lago Nahuel Huapf, Province of Neuquen (near the type locality) have been
