brighter coloured than eastern specimens, I propose the racial name 

 latirena, which will serve to distinguish it from pacifica. I consider no 

 description necessary, and make no type. Hampson does not figure the 

 type o^ pacifica, and his figure under that name is latirena. 



Quinquefasciata Sm. (Journ. N. Y. Knt. Soc, XVil, p. 65, 1909), is 

 a well-marked form of latirena, with distinct cross-lines and ventral shade, 

 which 1 have had in niy collection for fifteen years, and have often vainly 

 tried to separate out as a species. I am no better able to do so after 

 seeing the types, and believe it to be merely a varietal form, occurring 

 throughout the range of the latirena form oi hibisci. 



The synonymy of the above mentioned species will now stand :

T. mecrona Sm (Journ. N. V. Ent. Soc, XVI, p. 95, 1908). A good 

 species, I believe, described from Kaslo, and recognized by Mr. Cockle 

 and the writer two years before. It is the "grayer and smoother first 

 brood of communis " referred to by Dr. Dyar in the Kaslo list, and a large 

 number of the co-types of ccmimnnis are mecrona. 1 have separated them 

 in the Washington collection. It is characterized by being slightly larger 

 and longer winged, less red, having cross-lines fainter, orbicular usually 

 larger and rarely dark centered, and less of shade before s. t. line. The 

 two are very close allies, and must be well studied in good series to be 

 separated. I have a specimen from Oakland. Calif 



T. Smithii Dyar, its author refers, in Proc. U. S. Nat. Mus., XWTl, 

 p. 868. 1904, as "at least a different race from communis." The female 

 t) pe ai Washington is from " N. III.," and I believe it to be the same 

 species as Morrison's type of incinata, male, without locality, in the same 

 collection. It is a broader winged species than communis, with male 

 antennae bipectinate with rather long branches. A Colorado female there in 

 the incinata series, and one from Mr. Val. Fernaker {? Wisconsin), as well as 

 type Smit/iti, have double pale-filled t. a. line. Type incinata and a ? 

 " N. III." have it single, but they seemed to me all one species.
