228 Part I1f.—Eleventh Annual Report 
Genus Moraria,* T. and A. Scott. 
Ann. and Mag. ‘Nat. Hist., ser. 6, vol. xi. p. 213, March 1893. 
Anterior antenne short, seven -jointed ; inner branch of posterior 
antenne, small, one-jointed ; mandible palp, one-branched, two-jointed ; 
posterior footjaws, three-jointed, provided with a prehensile terminal 
claw ; first pair of swimming feet short; inner branches, two-jointed, not 
longer than the outer branches, joints subequal; inner branches of the 
second, third, and fourth pairs much shorter than the outer branches, two- 
jointed, joints subequal. 
This genus somewhat resembles Cylindropsyllus, Bradys in form and 
in some structural details. In the form and structure of the posterior 
antennee, mandibles, and first pair of swimming feet it resentbles both 
Attheyella cryptorum and Mesochra robertsoni, Brady, but it differs very 
markedly from both Attheyella and Mesochia in the structure of the 
second, third, and fourth pairs.

Length, exclusive of caudal sete, “62 mm. (7@th of an inch).  Bore- 
head produced into a short rostrum. ‘The anterior antennee in both mule 
and female are short, stout, and seven-jointed, the male antenne being 
hinge:l between the fourth and fifth joints, and adapted for grasping. 
The relative length of the joints of the female antenne are as follows :—

A stout sensory filament springs from the upper distal angle of the fourth 
joint in the female and the third in the male. T'rom the same joint in 
the male there springs a curved spine-like process from a produced basal 
part. Posterior antenne short, stout, three-jointed ; a small one-jointed 
secondary branch springs from uear the middle of the second joint. 
Mandibles well deyeloped, having a broad biting part and a one-branched 
two-jointed palp. The maxille cousist of a broad mastivatory portion and 
a two-branched appendage ; the truncate end of the masticatory portion 
is armed with five moderately long spine-like teeth ; there is also a small 
seta on the exterior margin ;| the outer of the two branches of the 
appendage terminates in a comparatively stout spe, plumose on the 
outer half, and is also furnished with four small marginal sete; the 
inner branch is small, and terminates in a small spine. Anterior footjaws 
stout, terminating in a stout clawed spine bearing a small seta on its outer 
margin near the base of the claw ; slightly anterior to the claw are two 
digitiform processes, each of which terminates in a moderately stout spine 
and an inward curved process not so long as the spine, and bearing several 
small setze on its interior distal margin. Posterior footjaws three-jointed ; 
last joint small, bearing a moderately slender, but not very long terminal 
claw. A stout plumose seta springs from the interior distal anele of the 
first joint; inner margin of the second joint fringed with cilia. First 
pair of swimming feet nearly as in Attheyella cryptorum, but the last 
joint of the inner branch is shorter than the first joint, being scarcely 
three-fourths its length; it is also narrower, and bears a stout terminal 
spine and two subterminal setzee—one very short and one very long and 
slender. ‘The second and third pairs of feet in the female are somewhat 
similar to those of Mesochra liuljeborgu, but the first joint is more dilated
