to the species included under this generic head by Hampson we describe 

 it as a Lithacodia in which genus it appears at least fairly at home. 



LiTHACODIA INDETERMINATA Sp. nOV. (PI. XVIII, Fig. 3). 



Metathorax with prominent scale tuft; abdomen with large tufts on 4th 

 and 5th segments ; primaries deep dark gray scarcely relieved by paler shading, 

 with obscure maculation ; t. a. line obscurely geminate, poorly defined and 

 rather irregularly dentate in costal half, strongly inwardly oblique below cell 

 and quite prominently black; a broad oblique costal patch in median area rather 

 paler than the ground color followed by a narrow dark shade which connects 

 with a small loop-like reniform, defined in black and open toward costa, con- 

 nected by a fine black line along vein 3 with t. p. line ; below this a faint ruddy 

 shade stretching across t. p. line; a faint black line from angle of t. a. line 

 through submedian fold but not reaching t. p. line ; this line obscure, geminate, 

 crenulate, outwardly bulging to vein 3 then curved sharply inward and again 

 straight below fold to inner margin ; beyond t. p. line at costa a slightly darker 

 patch defined below by a distinct short black line extending between t. p. and 

 s. t. lines; s. t. line pale, obscure, irregular, rather prominently bulging across 

 veins 3 and 4; faint broken dark terminal line; secondaries smoky. Beneath 

 primaries smoky, secondaries paler with distinct discal dot and faint post- 

 median curved line. Expanse 19 mm. 



Habitat : Winnfield, La. 1 2 . Type, Coll. Barnes. 



The species resembles somewhat a Sarrothrips, the primaries being 

 rather broad with the costal and inner margins semiparallel. 



HOPLOTARACHE ALBIOCULA sp. HOV. (PI. XVII, Fig. 12). 



Palpi white laterally; front and thorax with an admixture of white and 

 black scaling, the former with a raised circular process with tubercle on its 

 lower margin, abdomen smoky gray, untufted; primaries pale ochreous, heavily 

 suffused with blackish in median and subterminal areas ; basal area pale with 

 a fine black basal streak connecting with a long ill-defined claviform outlined 

 in black and filled with white and continued by a white line to s. t. line ; t. a. 

 line marked by an oblique dark streak from costa and a dentate mark at inner 

 margin ; median space largely dark except between the spots and beyond the 

 reniform; both spots prominent, white, the orbicular decumbent, oval, the 

 reniform large, rounded ; t. p. line not defined ; s. t. line commencing as an 

 oblique dark streak from apex and continued as a diffuse dark shade parallel 

 to outer margin with a small outward bend at inner margin ; the terminal area 

 more or less pale with slight dark shading ; fringes sharply black and white 

 checkered. Secondaries smoky with veins partially lined with black and 

 blackish fringes slightly pointed with white. Beneath pale smoky with dark 

 checkered fringes; traces of a diffuse s. t. line on primaries and a large discal 

 spot on secondaries. Expanse 22 mm. 



Habitat: Olancha, Inyo Co., Calif. 1 ?. Type, Coll. Barnes.
