Fic. 21. Tachardia minuta sp. nov., young larva; a, from beneath, X 165; adult female, }, 
outline of body, showing position of various organs, X 38.5; c, dorsal spine, X 230; d, 
stigmatic plate, X 385; e, marginal group of gland pores, X 335; f, details of pores in same, 
X 640; g, antenna, < 385; h, apex of anal lobe, X 335; i and j, spiracles, x 335. 
ances or tubercles on each side, each of these bearing a large 
stout spine, and anteriorly with the margin curving down more 
or less irregularly between the first spine on each side; anal ring 
with ten hairs, the longest about 50 y», the division of each lat- 
eral half of the ring into upper and lower portions indistinct 
or incomplete; apparently with only a single type of gland over 
the body, but with a few circular, indistinctly quinquelocular 
gland pores near each spiracle; body gland pores peculiar in 
appearance, but so minute that it has not been possible to de- 
termine the structure definitely; apparently oval to circular, 
and either trilocular, with the loculi in a single row, or obscurely 
quadrilocular with one pair of loculi larger than the other, these 
in two sizes, the smaller occurring scattered in the body margin 
region, in about four small loose clusters, forming a row on each 
side, and outside of this row in sixteen compact clusters, sur- 
rounded by faint chitinization, running clear around the body, 
of which clusters the four anterior are the largest, the large pores 
occurring only in these last clusters, in which there are two on 
the outer edge of each cluster except the fifth and sixth from 
the caudal apex on each side, these having only one, and from 
two to eight in the inner half of each cluster, the latter sur- 
rounded by smaller pores.
