of the anterior and middle tibial spurs are precisely the 
same as in the type of calcarata. The two species are cer- 
tainly the same. 
The known range of eniarginata is now from San Isidro- 
in Coahuila to west Texas and southeastern Arizona. I 
have the following additional records: Texas: Marathon, 
July 9, 1938 (K. U.) ; Culbertson Co., Aug. 30, 1947, D. J. 
and J. N. Knull (Ohio). New Mexico: Luna Co., Oct. 1 
(Ohio). Arizona: Douglas, Cochise Co., July 3, 1931, W. 
W. Jones (Parker) ; near Willcox, Cochise Co., Sept. 3, F. 
H. Parker, on flowers of Kallstroemia (Parker) ; Dragoon 
Mts., Cochise Co., Sept. 10, 1947, D. J. and J. N. Knull 
(Ohio and Werner).

Ochrea is probably one of the more abundant species of 
Epicauta in the area from west Texas to southeastern Ariz- 
ona, but is nevertheless very poorly represented in collec- 
tions. The reasons it is rarely collected would seem to be 
twofold : first, that most collectors don’t know where to 
look for it, and second, that most collectors who do know 
don’t care to. Specimens can be taken at the bases of leaves 
of yucca or bear grass {Nolina) almost any time during 
the summer. One encounter with the leaves of either plant 
is usually enough. Occasional individuals are seen in the 
daytime on flowers of yucca. One experience with the 
species on yucca flowers at night convinces me that it is 
primarily nocturnal, though not “attracted” to light. On 
July 29, 1948 we camped on the west slope of the Patagonia 
Mts., east of Nogales, Arizona, at 5330 ft. in the oak-juniper 
zone. On checking a small stand of a caulescent yucca short-
