14 PROCEEDINGS OF THE NATIONAL MUSEUM, VOL. 62. 
claw elongate, tapering, only slightly curved, without denticles, claw 
digitules slender setae, acute at apices, perhaps one-third the length 
of the claw, trochanters each usually with five pores above and below; 
thoracic spiracles large and conspicuous; abdomen elongate, parallel- 
sided, the margins of the anterior segments slightly bulging, those of 
the last three progressively more strongly protruding till the margins 
of the apical segment are produced into fingerlike fleshy protuber- 
ances some three or four times as long as wide; abdomen dorsally 
with transverse segmental rows of scattered quadrilocular gland pores 
and much more numerous slender setae, these last much longer at 
body margin, ventrally with setae only; abdomen probably with 
the same number of spiracles that are present in the female, but 
only the posterior ones plainly developed; sheath of penis elongate 
triangular, somewhat swollen at base and sharply pointed at apex, 
length 500y, width at base 207y. 
Holotype and paratypes.—Cat. No. 25269, U.S.N.M. 
This species has been described from six adult females and one 
male mounted on slides and from a number of unmounted females, 
all collected on Eucalyptus at Brisbane, Australia, by George Compere 
under his No. 1130. 
MCNOPHLEBULUS SUBTERRANEUS, new species. 
Reference.— Monophlebus, sp. Koebele, U. S. Dept. Agri. Diy. 
Ent. Bull. 21, 1890, p. 21. 
Adult female.—Occurring on the roots of the host; elongate oval, 
strongly convex, broadest and somewhat swollen behind the middle, 
maximum length 22 mm., width about 10 mm., reddish brown, mot- 
tled in abdominal region with blackish (alcoholic specimen); color 
when received dead in Washington dull, dark brick red, according to | 
notes made by Theodore Pergande; with only faint traces of secre- 
tionary covering, also according to Pergande; body as flattened on 
slide rather uniformly oval, maximum length 22 mm., maximum 
width 14 mm.; derm rather more heavily chitinized than in related 
species, remaining yellow brown after treatment with potassium 
hydroxide; antennae small compared to size of body, 9-segmented, 
stout and tapering, the terminal segment longest, legs a little larger, 
but small and fairly stout, the heavy spines on the tibia and tarsus 
distinctly longer and more slender than those of the other species in 
the genus; beak small, more elongate triangular than in the other 
species of Monophlebulus, very obscurely 2-segmented; thoracic and 
abdominal spiracles similar in number and appearance to those of 
related species, but with the pores accompanying each spiracle more 
numerous than with the other species; derm pores and setae each 
surrounded by a more or less distinct circular to oval clear area in 
the yellow brown derm; derm pores, in general, entirely comparable
