(After Howard and Marlatt.) As the term "metacoxal line" is used extensively in the key, I quote from Dr. Horn's Revision of the genus as follows: '' The first ventral segment exhibits the character of greatest value in the division of species. Behind the coxal cavity is a slightly elevated line beginning at the inner edge of the cavity passing more or les^ obliquely and curved toward the first suture, sometimes joining the suture and continuous with it (Pig. 194, No. 1), or running parallel with the suture (Fig. 194, No. 2), or recurving to the front and when entire ending near the f'-ont angle of the segment, (Fig, 194, No, 4), In the present essay this line is called the 'metacoxal line' " Casey calls Ihe linas "abdominal lines," To see them plainly the hind femora must l)o lifted up or pushed to one side and.
