Fig. 11. Sy anth us bispinosus g. et sp. nov., adult female; a, antenna, xX 165; b, leg, 
165: ¢ to g, five different types of gland pores found on body, X 640; h, tarsal claw, 
X 640; i, outline of body, showing arrangement of spine groups, 45; j, lateral abdominal 
spine group, X 640; k, median abdominal spine group, X 640; 1, apex of abdomen, X 165. 
tubular ducts with two or three minute circles attached to their 
outer margins, these two on the anal lobe segment, four with 
one pair marginal on the next segment anteriorly, six with one 
pair marginal on the next, and eight with one pair marginal on 
the remaining abdominal segments, these gland tubes also pres- 
ent, but in fewer numbers and uncertain arrangement, on head 
and thorax; next in size, with somewhat smaller, flat, circular 
disk glands with minute central pore and crenulations, possibly 
representing openings, near the outer margin, normally with 
four of these on the anal lobe segment, eight on the next 
anterior, and an increasing number on the anterior abdominal 
segments, and in the thoracic and head region, these usually 
more or less grouped in connection with the larger glands 
previously described; finally with a much larger number of 
the ordinary triangular and trilocular gland pores scattered 
over the whole dorsum and margin; ventrally with large disk 
glands already described for the dorsum but much more numer- 
ous, in transverse segmental rows, with tiny tubular glands
