Moeopsylla gen. nov. 



Head. A small pointed frontal tubercle directed backwards, is situated close 

 to the antennal groove (PL 1 f. 1). The oral edge is very short, the mouth-parts 

 being directed downwards. The lower angle of the oral edge is enlarged into a blunt 

 tooth-like lobe. The upperlip . and mandibles are broad, the former bearing a number 

 of widely seperated tubercles along the upper edge from the base to the tip. The 

 mandibles are encased in the rostrum formed by the labium and the two labial palpi. 

 The latter reach to the apex of the forecoxa. The labial palpi are not completely 

 divided into segments, the segmentation being indicated only at the anterior edge 

 (PL 1 f. 2). The eye is large. The antennal groove is closed. The first segment of 

 the antenna of the J 1 is large, the second segment being transverse, almost rectangular, 

 bearing a transverse row of bristles, which are specially long in the ?. besides smaller 

 bristles. The club of the antenna is of the Pulex-type, being short, and its anterior 

 side non-segmented. Thorax. The thoracical segments are short, with one row of 

 bristles on each tergite and no comb. The rostrum projects downwards in between 

 the forecoxae. The sternite of the mesothorax is narrow, the pleural portion being 

 vertical and not divided by a suture. There is however an internal incrassation ex- 

 tending from the insertion of the coxa obliquely forward ending at the anterior edge 

 of the sternite on a level with the ventral outline of the prosternum. The stigma 

 of the mesosternite is placed some way from the coxa. The episternum of the meta- 

 thorax is large. The epimerum is of the Pulex-type, being much more extended in 

 a vertical than in a longitudinal direction. Abdomen. --In shape similiar to that 

 of Puhx, the segments bearing very few bristles. There is one moderately long 

 subapical bristle on the seventh tergite, placed away from the edge of the segment. 

 Legs. - - The hindcoxa is somewhat pear-shaped, the posterior edge not being deeply 

 excised, but slanting considerably from beyond the centre to the apex, on its inner 

 surface there is a patch of short spines. The first tarsal segment of the fore-and 

 midtibia is shorter than the second. The fifth is long. The claw is also long and 

 slender, with a small basal tooth. Modified segments. -- cf. The eighth sternite 

 is large. The ninth tergite has two manubria on each side, the lateral portion of the 

 segment not being separated by a suture from the dorsal portion which bears the 

 sensory plate. There are two free lateral processes on the tergite. The ninth sternite 

 lacks an internal vertical arm. ?. The stylet is present. The eighth tergite is large 

 and completely divided in the dorsal line. 



The vestigial segmentation of the labial palpus and the strong serration of the 

 mandibles are very interesting features in the organisation of this new species, which 

 approaches the Sarcopsyllids.
