Sept.-Dec, 1920.I FORBES : NoTES OX THE CrAMBIN.E. 221 



C. intermedius Kcarfott. Gillett (Karnes Co.), Tex.. June 25, 1917; Rich- 

 mond, Tex., June 22, 1917; Columbus, Tex., May 21, 1918. 



C. nevadellus Kearf. Victorville, Cal., May 30, 1918. 



C. dimidiatellus Grt. Mesquitc, near Mesilla Park, X. M.. July 12, 1917; 

 Phoenix, Ariz., May 7-8, 1918. 



Genus Haimbachia Dyar. 



The condition of the tongue seems unstable in closely related 

 species of the Crambince, and the presence of the ocelli would seem a 

 better character to separate this genus from Diatrcva. Sc of the hind 

 wing also appears a little shorter. I believe the genus should be ex- 

 tended to include damon, squamidclla, prosenes and parallela. H. 

 damon has reduced ocelli distant from the eye, and will form a tran- 

 sition to Di-atrcra, but I cannot see the connection with Plafytes. 

 Squamidella, prosenes and parallela do not seem to differ in any sig- 

 nificant way from placidella, in fact squamidella is very close. The 

 latter is generally confused with a related species which has a well- 

 marked conical front, but if I am right in my determination the front 

 is smooth in the true squamidella. Parallela is different in appear- 

 ance, but the rest immediately suggest placidella in the course of the 

 t. p. line close to the margin. Venosalis Dyar should be compared 

 with Diatrcra. (Ins. Ins. Men., 5, 87.) 



Genus Thaumatopsis Morrison. 



T. pectinifer Zell. Victoria, Tex., June 24, 1917, at light. 

 T. edonis Grt. Brown's Mills, N. J., Sept. i, 1919. 



Genus Ommatopteryx Kirby. 



0. texana Rob. New Braunfcls, Tex., June 26, 1917; Texas Pass, Ariz., July 

 19, 1917, Xeedles, Cal., Apr. 1-6, 1918; Indio, Cal., May i, 1918. 



Examination of the genitalia shows that our species is structurally 

 distinct from the old-world O. ocellea. The principal difference is in /^^^ 

 the row of spines on the sedeagus, which consists of 13 or 14 rather 

 short and similarly formed spines in our species, but in ocellea has 

 two types of spines, the twelve or fourteen proximal much like these 

 of ours, but followed by a more distal series of nearly as many more 

 slender closely crowded spines.
