median lobe, one just outside of the outer lobule of the second lobe, one 
beyond the rudimentary outer lobule of the third lobe, one about 
half-way between this and the base of the pygidium and a group of 
two to four just caudad of the base of the pygidium; spines as shown in 
figure; anal opening circular, slightly nearer to base than to apex of 
pygidium ; circumgenital gland openings arranged in five groups, median 
8-9, anterior laterals 10-15, posterior laterals 7-10; marginal gland open- 
ings as follows: one between the first and second lobes on a slight 
prominence, one on a slight prominence between second gland spine and 
inner lobule of third lobe, one just beyond this, opening at the outer 
angle of the inner lobule of the third lobe, one, the first of a row, ona

slight prominence a little beyond the third gland spine, one a little 
beyond this, a little inside of the margin, apparently opening into a 
pocket, one on a slight protuberance beyond the fourth gland spine and 
the last a little beyond this; dorsal gland openings somewhat variable, 
but about as shown in figure; micropores so far as observed as follows: 
two, one in front of the other, cephalad of the outer lobule of the sec- 
ond lobes, one close to the second gland opening of the first row of 
dorsal gland openings.

This species has been found in two places just outside of 
Indianapolis, Indiana, September 15, 1915, and in two places 
east of Vincennes, Indiana, August 31, 1915, in all cases on 
the honey locust (Gleditsia triacanthos), infesting especially 
the green spines on the trunk of the tree, but also to some ex- 
tent the bark, twigs and leaves. In all cases it was scarce, and 
cannot be considered as being of economic importance.
