DESCRIPTION OP THE SPECIES. 247 



the second begins at the tip of the second longitudinal vein and 

 runs in an oblique direction over the posterior crossvein to tke 

 posterior margin ; between these two bands there is a short, 

 brown one, extending from the anterior margin to the third 

 longitudinal vein; it follows the same direction as the second 

 baud; the tips of the third and fourth longitudinal veins bear 

 each a small brown spot and these spots are connected by a nar- 

 row brown shade along the margin of the wing ; a small brown 

 spot covers the end of the anal cell, which is drawn out in an 

 acute point; the inner costal cell, the beginning of the first basal 

 cell, as far as the origin of the third vein, the basis of the sub- 

 marginal cell as far as the first brown crossband, the stigma and 

 the anal cell are tinged with yellow ; a yellow coloring likewise 

 surrounds that crossvein, which divides the second basal cell from 

 the discal cell ; the basis of the exterior costal cell is tinged with 

 yellowish-brown. The third longitudinal vein is, in the vicinity 

 of its origin, densely beset with bristles; more sparsely beyond 

 that point ; the third and fourth longitudinal veins somewhat 

 diverge towards their end ; the small crossvein is a little before 

 the middle of the discal cell; the posterior crossvein is straight 

 and steep. '.

Observation. The principal difference between this species 

 and the typical Spilographae consists in the structure of the head, 

 which has been described above ; moreover, the wings are com- 

 paratively shorter and the third vein has, as far as its tip, an 

 entirely rectilinear course, while, in all the species of Spilo- 

 grapha (comp. Tab. X, f. 7), it is gently curved backwards. 

 Should a new genus be founded for this single species, the name 

 (Edicarena, alluding to the structure of its head, might be 

 adopted for it. It would seem preferable, however, until a 

 number of allied species becomes known, to let T. tetanops 

 remain in the genus Spilographa, with which it is undoubtedly 

 related on account of the great resemblance of the picture of its 

 wings with that of T. electa and still more of T. flavonotata.
