Mawobasis immaculata is among the largest blister beetles found in Kansas.A number taken at Garden City averaged 17.5 mm. long by 4.5 mm. wide.Blatchley gives the limits of its variation in length as 13 to 23 mm. Color grayto light reddish brown. According to Blatchley, the sexes are distinguished bythe third antennal joint in the male being longer than the second, but in thefemale of only equal length or shorter. 8 BULLETIN 967, U. S.
