apud marginem wteriorem albido-Jiava," Mr. Walker has recorded 

 specimens of the present species. 



HEMEEOPLANES, Hiibner. 



Hemeroplanes pseudothyreus, n. s. (Plate 1, fig. 1.) 

 CalHomma oiclus / H-S., Corr. Blatt. p. 57. (1865.) 

 Not Sphinx oiclus Cram., PI. 216, fig. F. (1782.) 



Dull chocolate-brown ; beneath paler, mixed with cinereous scales. 

 Head produced, elongated, somewhat flattened, eyes large and salient; 

 maxillse well developed ; prothoracic parts well extended before the 

 insertion of the primaries. Anterior wings pale brown, a roundedly 

 oblique blackish basal line, within which, on costa and below sub-costal 

 nervure, are large blackish marks. Beyond, an outwardly rounded, 

 oblique, blackish transverse line runs from costa to internal margin, 

 which it joins near the base. Space between this latter line and the 

 basal line, paler than the rest of the wing. Median space large, darker 

 shaded in the interspaces between the nervules posteriorly, where it 

 acquires a faint purplivsh reflection ; on the discal cross-vein a somewhat 

 L-shaped white mark, above which a second, smaller, ovate and ob- 

 liquely placed. From the internal margin a blackish irregular line 

 extends to the larger white mark and runs partly parallel to the trans- 

 verse anterior line. Transverse posterior line blackish, undulate, out- 

 wardly arcuate, followed by a paler coincident shade. Subterminal 

 space paler, acquiring with other portions of the wing an obsolete 

 greenish tinge which is diflicult to define. In the post-apical interspace 

 a large, distinct, irregularly triangular, black spot. A black undulate 

 line margins inwardly a very narrow, darker, terminal space, which 

 extends from immediately below apex to below first median nervule, 

 somewhat as in the genus Eni/o. 



External margin of the wing excavate, resembling the species of 

 Eni/o, and in a less degree Thi/reus abbofii, to the general coloration 

 of which the present bears a resemblance which has suggested the 

 specific name. Apical interspace not excavated ; from post-apical to 

 medio-superior nervules the excavation is somewhat abrupt and deep. 



Posterior wings resembling anterior in coloration. Pale at base ; 

 crossed by a diff"use prominent median blackish shade band, beyond 

 which the wing is paler. From anal angle, which shows a few mixed 

 whitish scales, a narrow black line runs towards costa, but is lost before 

 traversing half of the wing. A terminal dark brown shade band, 

 broadest at costa, becoming obsolete before anal angle. 



Beneath, the wings are paler than on upper surface. Both pair tra- 

 versed by a very distinct (especially on posterior pair) tremulous black-
