'J'vpe species P/if/Uopodojisi/Z/us Bradi/i, T. Scott. De- 

 PciiU'il in 1^U2 under the name of " Tetra(jonireps Brndyi,

litmarka. — This species, whicii appears to be scarce, but 

 vith a tairly wide distribution, has a close resemblar.ee to 

 TitfLUjoniceps^ G. S. Brady. The anterior anteniue, however, 

 are composed of nine joints and it is the second (not the first) 

 joint that is strongly toothed. There is a difference in the 

 structure of the maxilhe and first maxillipeds, but the most 

 obvious difference is in tiie structure of the fifth pair of thoracic 

 feet, which are so large and leaf-like that they enclose the 

 entire ovisac. The species is described and figured in the 

 Fishery Board Report referred to above. 



Genus Pteropsyllus*, T. Scott, nov. (PL XI. figs. 7, 8.) 

 Syn. Tetrayonireps, T. Scott, in part, (not Tetrayomccps, G. S. Brady). 



Description. — 'J'his genus resembles in some respects the 

 one last described, as well as Telragoniceps^ G. S. Brady, and 

 seems to hold a somewirat intermediate position between 

 them. 'J'he anterior antennie are composed of eight joints; 

 the first is elongated, the second is shorter and has the upper 

 distal angle produced forward.s into a tooth-like process, and 

 the fourth is provided with a sensory filament. Posterior 

 antcnnaj aiiparently three-jointed ; outer ramus rudimentar}-, 

 consisting of a minute uniartieulate joint. J\landible and j)alp 

 as in Tretrufjoniceps. The maxilhe and maxillipeds are also 

 somewhat .similar to those of the .«ame genus. Both branches 

 of the first pair of thoracic feet three-jointed; the first joint 

 of the inner branch is as long as the entire length of the outer 

 branch, but the second and third joints are small. The next 

 throe pairs have the inner branches two-jointed as in Pliyllo- 

 podoitsyllus. In the fifth j)air the basal joint is small, hut the 

 secondary joint is large and foliaceous — large enough to 

 enclose the ovisac. Abdomen composed of four segments. 

 Fnrcal jnints tolerably elongated. 



No nnile observed.

 wing-like.
