T. robustella, Zeller, [Tetralopha), Isis, 88 1, 1848. Groie, 

 (^Tetralopha), Geol. Surv. Terr. Bull, IV, 690, 1878. 



Head and thorax fuscous gray, abdomen yellowish. Fore wings cloudy fuscous 

 gray with a slightly russet shading at times. Middle field lighter, just beyond basal 

 line often light gray. A cross band of larger scales on basal field rising into a black 

 tufting near middle. Another near middle of middle field, often forming a dentate 

 black line, sometimes only scattered black dots, this scale ridge also with 2 oi- 3 tuft- 

 ings. Outer line quite even, strongly bent. Hind wings light jjellucid fuscous, outer 

 line evident darker fuscous. Expands 18 to 25 nun. 



Central Texas, August. I ha\-e not been able to examine the 

 venation of this insect but have Utile doubt it belongs to Lanlhaplie 

 rather than Tetralopha. As determining Tetralopha I take the first 

 species described under it, viz ; ?>iiii/c/Ia, Zell., as the type of the genus.
