Mi tico. Cordoba, one female "at light" (Knab). 



Guatemala. Sapachiti, April, 1902, one female (R. F. Griggs). 



Guatemala. Alt a. Paz, Socanquin, cotton field, one male (A. 

 MacLachlan). 



Mexico. — ( )ne female. 



Paraguay. Sapucay, male and female (W. Foster); a small, red 

 male and female. [See Rehn, 1907", p. 151, and Caudell, 1904, p. 

 181.] 



Brazil. -Bonito, Province of Pernambuco, "mi cotton," January 

 5, 1883, three females and a bleached male. Same locality, five 

 females and three males of the califomica form. [See Rehn, 1903 2 , 

 |). 310.] 



Venezuela. Merida, one male and two females (S. Brieno). 



Mexico. Ori/aha,, January 9 to 1(>, 1897 (II. Osborn), var. cali- 

 fomica; det. Rehn [1903 2 , p. 310]. 



'fi.ras. Brownsville, November, 1904 (11. S. Barber), one male, 

 determined by Caudell as .1. exilis. 1 do not know the true exilis, 

 but consider this identical with the var. califomica. 



. Vrizona. Tucson, one male. 



Cuba. Cayamas, one male and one female (Schwarz). 



I look upon this as a rather variable and widely distributed spe- 

 cies; 1 consider tseniata, luteipes, ami <i<u/<<tt<t a- synonyms; also 

 califomica, which is a variety; also gracilis and suturalis; perhaps 

 exilis is distinct. 



Rehn agrees in regarding califomica as a mutation. Caudell is 

 righl in adopting Eschscholtz's old name. 



The development or abbreviation of the wings, the presence or 

 absence of a tooth on the forceps, the intensity of coloration, the 

 breadth of the bands on the elytra, are not features which, in m\ 

 opinion, justify specific rank. It may be possible to show, when all 

 the available material has been critically examined, thai some of 

 t he forms are restricted to certain localities, in which case they become 

 local races, or variation in the sense as defined by Staudinger, Tutt, 

 and other ledidopterists. 



2. ALBIPES Fabricius. 



Santo Domingo. San Francisco Mountains, two males and one 



female I Busck ). 



These are Caudell's original specimens [1907 1 , p. 169]. Perhaps 

 albipes Fabricius and bimaculata Fabricius are identical. 



Genus ELAUNON Burr.
