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, on a 



Phenacaspis spinicola n. sp. Pygidium of female, dorsal surface to right, 

 ventral surface to left. (R. E. Snodgrass, del.) 



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

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 (Glcditsia 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.
