A NEW NOCTUID. 



By R. OTTOLEXGUI. 



Thyatira rectangulata nov. sp. Pattern essentially that of T. scrip/a 

 (America) and T. derasa (Europe), except that in the course of the t. a. 

 line a sharply defined right angle occurs ; hence the name. This serins 

 to be a specific character, as in derasa the line is practically straight, 

 whilst in scripta there is a slight bend at the point where the right angle 

 occurs in rectangulata. Other differences are as follows : 



Color. The ground color is the same in all three species, lightest in 

 derasa, and darkest in rectangulata. The maculation in derasa is creamy 

 white with a deep yellowish cast through the central third of the prima- 

 ries. In scripta there is a pinkish hue to the white markings, and, with a 

 number of specimens before me, it is evident th.it there is a yellowish re- 

 flection through the central third of primaries, a shade which is entirely 

 absent in rcclan^ulata, the markings of which are bright pink. In fact, 

 both in color and pattern (with one exception), scripfaseems more nearly 

 allied to derasa, than it is to rectangulata. 



Subterminal line. In scripta and derasa the s. t. line is a distinct white 

 band, well defined along both edges, extending uninterruptedly from a|>.-\ 

 to cuter angle. In rectangulata the line is narrow, sharply d-.-nt.itc out- 

 wardly ; inwardly fading away and blending with the ground color ; it is 

 narrowed or broken near the angle. 



Subterminal space. The subterminal space in all three species :-*
