Besides those enumerated above it is likely that subsimilis Casey 

 and perhaps leporina Mulsant belong here. 



Of the typical 5-signata only one female from Escanaba, Michigan 

 (Hubbard and Schwarz) has been studied, but the pronotal and 

 elytral markings are so similar to certain of the western subspecies 

 and varieties that there is hardly a question but what it is correctly 

 placed with them. This and the subspecies of the Rocky Mountain 

 region are characterized by the heaviness of the elytral markings in 

 varying degrees and in some forms by the brilliancy of the ground 

 color. Of coccinea a male from Buena Vista, Colorado (Hubbard 

 and Schwarz) has been studied. Of vernix specimens from Mullan 

 and Helena, Montana (Hubbard and Schwarz) ; Moccasin, Montana 

 (S. J. Snow) ; and Buhl, Idaho (L. P. Rockwood) have been ex- 

 amined. Specimens of uteana have been studied from Enterprise, 

 Utah (T. R. Chamberlin) and Kaysville and Salt Lake City, Utah 

 (P. H. Timberlake). 



Uteana was found in the vicinity of Salt Lake City quite infre- 

 quently during the summers of 1913 to 191 5. None was seen in the 

 summer of 1913, one male only was found on alfalfa in the fall of 

 1914, but in July, 191 5, some half a dozen specimens were discovered 

 among great numbers of convergens and sinuata disjuncta on the 

 flowers of poison hemlock infested with Aphis hcraclei Koch. All 

 that were found in 1915 were brought to the laboratory and kept 

 under observation for weeks. It is interesting to note that two or 

 three of the females proved to be infertile when captured, thus sub- 

 stantiating the rarity of the spcies in that locality. From these speci- 

 mens a good series was reared, showing an interesting amount of 

 variation. Some of the beetles, except for the more brilliant colora-
