Genus APICIA Guenee. 



APICIA ISCHYRIZOARIA, new species. 



Fore wing with the apex pointed, the outer margin angled at veia 

 4; straw-color, more or less distinctly tinged with brown; lines nearly- 

 straight, approximating on inner margin, whitish, edged with brown 

 within, the brown edging usually more obvious than the line itself; a 

 rounded black discal dot ; basal and terminal spaces dusted with purplish 

 black irrorations, which form large clouded spots, one in center of 

 basal space, three following outer line and one within the angle of the 

 outer margin. These spots are sometimes confluent, sometimes faint. 

 Hind wing with a single mesial line, followed by a central spot, 

 which may be duplicated toward inner margin or have small patches 

 toward apex and outer margin; discal dot present or absent. Ex- 

 panse: Male, 31 mm.; female, 37 mm. 



Two males are dark rusty brown with the patches pale purpHsh 

 and confluent. The females are both pale, with the patches pale 

 purplish and confluent, but faint. 



Cotypes. — Nine males, two females. No. 14244, U.S.N.M., Mexico 

 City, Mexico, February, May, June, September, October, December, 

 1908, 1909, 1910 (R. Miiller). 



Mr. Schaus kindly examined both sexes of this species. The 

 female he found to resemble Tlierina ascolia Druce, while the male 

 might be easily mistaken for one of the forms of the female of Apicia 

 distycharia Guenee. The species comes very close to Tetrads pago- 

 naria Schaus, which is represented in the collection by females 

 \\dthout any traces of the purplish patches. In the females of ischy- 

 rizoaria before me the purplish markings are much fainter than in 

 the males, and it is possible that they may disappear. 



Genus THERINA Hubner. 



THERINA CALIDARIA, new species. 



Wings semitranslucent pale brownish straw-color, densely irrorate 

 with purple brown; lines purple brown, edged with dark ocher, nar- 

 row, shghtly spotted on the veins, the outer line incurved a little 

 below cell; a dark discal mark. Hind wing with a single outer 

 mesial line like those on fore wing. Expanse, 35 mm, 



Cotypes. — Three females. No. 14245, U.S.N.M., Zacualpan, Mexico, 

 August, 1909, 1910 (R. Miiller). 



Genus TRYGODES Guenee. 

 TRYGODES SIMPLICISSIMA, new species. 



Wings translucent whitish, thickly irrorated with pale gray, the 

 irrorations largely confluent; fore wing with two lines of gray, 

 wavy, approximate, subparallel; hind wing with a single mesial line;
