DELTOTARIA MILLIPEDS—HOFFMAN 29 
Head of normal contour, not strongly convex; genae with distinct 
median groove; vertigial suture’distinct, with a single row of small 
punctures. Labral setae 6-6 (the series interrupted above the labral 
teeth), clypeal setae 8-8, not extending laterad onto genal margins. 
Antennae long (6.8 mm.), extending back to fourth tergite, the 
articles in decreasing order of length 2—5-6-3-4-1-7. Interantennal 
isthmus proportionately much narrower than in brimleit (18 percent 
of antennal length instead of 25 percent). 
Collum distinctly narrower than the second tergite. 
Metatergites with distinctly depressed paranota, which continue 
the dorsal convexity; dorsal surface of paranota and of middorsal 
region, particularly of segments in the posterior half of body, coriaceous, 
most distinctly so just behind the interzonal furrow, the sculpture 
visible to the eye without magnification. Peritremata only moderately 
developed, and do not on any segment project beyond caudal edge of 
the paranota (fig. 1e). Paranota of segment 19 in the form of short, 
rounded lobes. 
Caudal edge of segments set off on the sides by a tiny narrow sub- 
marginal ridge, without a distinct submarginal furrow; sides of most 
segments with a distinct low conical knob above base of the posterior 
leg pair. Interzonal furrow very distinct down sides, and especially 
so in front of the stigmata. 
Podosterna distinctly elevated, forming a nearly flat surface, which 
slopes abruptly down to the level of the prozonite well behind the 
interzonal furrow; surface of podosterna of most segments posterior 
to the gonopods with a distinct median subcircular shallow depression. 
Sternal setae reduced both in size and number, occurring in about four 
pairs only on segments 8 through 10, near the base of the coxae. 
Gonopod aperture large and transverse, of the form as shown in 
figure 1h, the caudal edge slightly elevated above level of the inter- 
coxal surface of the segment. Coxa of gonopods large, the coxal 
apophysis of about average size and shape for the genus. Prefemur 
with a low, rounded knob on the coxal side, distad of which the telopo- 
dite blade is rather abruptly recurved and attenuated, becoming 
narrower to the distal fourth where distinctly broadened by a lobation 
of the outer margin, and here provided with a small, thin, acute, 
submarginal dentate flange probably homologous with process B of 
brimlett and brimleardia. Distad to the expanded portion the tel- 
opodite is continued as a slender, curved, solenomerite. 
VARIATION: Specimens taken near the type locality agree in most 
particulars with the preceeding descriptive notes but differ consider- 
ably in size. The males are not only smaller than the holotype, but 
are also smaller than the females collected with them. Six males 
range in length from 26 to 32 mm. (average, 28.5 mm.) and from
