420 ON .SPECIES OF HADENA SMITH. 



Lateritia, or, as it is geuerally uaiued, dubitans, is reddish brown, and 

 recalls somewhat some species of the cariosa group (genialis) ; but dif- 

 fers evidenth'. The primaries are proportionately somewhat longer 

 and less obtuse than in the other members of the group. The harpes 

 and tip of S are of the usual form, the interior edge somewhat sparsely 

 spinulated. The clasper is distinct, rather stout, and reaches rather 

 more than half way to the end of tip. 



Cogitata closely resembles lateritia and is generally confused with it. 

 It differs at sight in the more obtuse primaries and more discolored 

 reniform, but otherwise the markings are very like its ally. The geni- 

 talia are quite distinctive; the clasper is much longer than in lateritia, 

 and there is a supplemental process at the base of the long hook. 



Sputatrix differs evidently from lateritia not only in color, but in the 

 more obtuse primaries. The ground color is dark blackish brown, the 

 median lines obsolete, and only the strongly pale marked reniform 

 prominent. The tip of harpes is much as in lateritia ; but the clasper 

 is much longer and rather more slender. There is also an additional 

 small, slender, curved, chitinous hook at about the middle of the harpe. 



Pluionia is smaller than either of the preceding, as dark as sputatrix, 

 but with the reniform only narrowly pale marked outwardly, and a dis- 

 tinct black streak along internal margin near base. The tip of S harpes 

 is distinctive and rather peculiar. The outer margin is somewhat 

 rounded, the superior margin broadly lobed, and furnished with a brush 

 of hair ; the inner margin has a narrow series of spinules nearly to the 

 junction with main shank of the harpe, and here there is a tuft of diver- 

 gent spinules. The clasper is short and straight, arising from inferior 

 margin of side piece close to tip. 



The differences are sufficiently noted without again giving them in 

 synoptic form.
