Plagioinimicusj^ n. g. 



Ocelli. Eyes naked, without lashes. Clypeus with a broad naked cup-like 

 depression, the raised edges forming inferiorly a wide semicircular corneous 

 projection, beloAv which a corneous ridge crosses the face above the moderately 

 slender maxillae. Labial palpi shorter than usual. Legs unarmed. Fore 

 tibiae with a stout terminal curved spine. Antennae simple, with short hairs 

 beneath on the joints {$). Squamation scaly, as in Lygranthoecia, not hairy, 

 as in Heliolonche and Heliothis. Thorax short and square ; tegulae laterally 

 spreading, with elevated terminal scales. Abdomen without tufts, very little 

 exceeding the hind wings. 



Plagiomimlcus pityochromus, Grofe. 



$ ? . — Color of Lygranthoecia marginata and L. TJioreaui. Median lines 

 narrow, distinct, white ; transverse anterior a little inwardly depressed in its 

 general course above the median vein, about which it forms a faint angle, 

 thence straightly to internal margin ; transverse posterior running outwardly 

 from costa to vein 6, where it is angulated, thence descending with an inward 

 sweep evenly to internal margin which it joins (running inferiorly parallel 

 with the t. a. line) at within p;j from the base, narrowing the median space 

 inferiorly. Discal siwts evident, elongate, lying in slightly opposed posi- 

 tions, black (especially the orbicular), surrounded by narrow white borders, 

 constricted medially, figure 8-shaped. Subterminal line preceded on costal 

 region by a darker, large triangular shade which obtains between the t. p. and 

 s. t. lines superiorly. Hind wings a little paler than jirimaries, similarly tinted, 

 plain. Beneath without markings ; fringes concolorous. Body parts like the 

 wings. 



E.qianse, 2^ m.. r\\. Hahitat, A\i\hixn\\x\ Albany (Lintner). Size 

 of Lygranthoecia marginata, with the primaries more widely trian- 

 gulate. From both species of Lygranthoecia, specifically easily 

 separable by the paler more olivaceons general tint, the apically 

 produced transverse posterior line and the distinct guttiform discal 

 spots, and generically by the frontal excavation. The type is in the 

 collection of this Society.
