Part III.~-Mcvcnth Annual Report 



Genus Moravia* T. and A. Scott. 

 Ann. and Mag. Nat. Hist., ser. 6, vol. xi. p. 213, March 1893. 



Anterior antennae short, seven -jointed ; inner branch of posterior 

 antenna?, 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, Brady, in form and 

 in some structural details. In the form and structure of the posterior 

 antenna?, mandibles, and first pair of swimming feet it resembles both 

 Attheyella cryptorum and Mesochra robertsoni, Brady, but it differs very 

 markedly from both Attheyella and Mesochra in the structure of the 

 second, third, and fourth pairs.

Length, exclusive of caudal setae, *62 mm. ( T ^thof an inch). Pore- 

 head produced into a short rostrum. The anterior antennae in both male 

 and female are short, stout, and seven-jointed, the male antennae being 

 hinged between the fourth and fifth joints, and adapted for grasping. 

 The relative length of the joints of the female antennae are as follows : — 



6-8-6-5-5-7- 10 ■ 

 X - 2; 3, : 4 ; 5 * 6 • 7 • 



A stout sensory filament springs from the upper distal angle of the fourth 

 joint in the female and the third in the male. From the same joint in 

 the male there springs a curved spine-like process from a produced basal 

 part. Posterior antennae short, stout, three-jointed ; a small one-jointed 

 secondary branch springs from near the middle of the second joint. 

 Mandibles well deyeloped, having a broad biting part and a one-branched 

 two-jointed palp. The maxillae consist of a broad masticatory 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 spme, plumose on the 

 outer half, and is also furnished with four small marginal setae ; 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 setae 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 angle 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 setae — 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 lil/jeborgii, but the first joint is more dilated
