the fork very asymmetrical, one branch Leung nearly absent and the 

 other almost like a continuation of the rod ; there is a somewhat strongly 

 chitinised part of the adjacent membrane densely studded with minute 

 asjjerities. 



The tegmen has a small bridge (not, however, so minute as in the 

 allied genera) ; the strut is stout, much dilated at the extremity. 

 Median lobe sti-ongly bent, the apex a little prolonged and recurved 

 and nearly truncate, just visibly emarginate ; the struts are long and 

 broad, connected with the bodj^ by a slender junction ; median orifice 

 pl.iced far from the tip, and owing to the abrupt deflection looking 

 backwards as much as upwards, it exhibits a pair of definite hard pieces 

 (volets or hinge apparatus), the diameter of the body is swollen on each 

 side of the median orifice. 'J'he sac is large, as long as the struts, with 

 a small secondary lobe concealed by the tegmen-strut ; the apical part 

 densely covered by minute structures making it dark and the transfer 

 apparatus difficult to see, but apparently it is of the dujilicate form, 

 much as in other Phalidurinae. I see no subtegmmal diverticulum. 



The only specimen of this interesting insect has apparently lived 

 among some pallid clay, which adheres and obscures the minnte 

 clothing.

This genus is probably a composite one, as it is defined by negative 

 characters, and will com[)rise those species at present placed in l*haluhira 

 in which the last dorsal is folded back behind the forceps without bulging 

 forwards between their blades, though in some species it sends long hairs 

 between the blades. The tj'pe is P. impressa (Boisd.) which may, 

 as previously stated, ]jrove to be mi rah/ /is Kirby. This insect has the 

 membrane of the 8th ventral plate provided with a vertical lamina as in 

 Phalidura. and should there be similar species without a lamina, they 

 should be rejected from the genus. P. aloanei Ferg., hrei'ij'oniiis F., 

 and probaldy other of his Psalidarae belong to it.

The type of this genus is Talattrinus riverinae MacLeay. The 

 characters are that the two divisions of the last ventral are hard thick 

 pieces, not forming forceps, but coming to the surface where they are 

 visible, as minute acuminate tubercles at the outside of the last dorsal,
