A NEW NOCTUID. 



By R. Ottolengui. 



Thyatira rectangalata nov. sp. — Pattern essentially that of T. scripta 

 (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 seems 

 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 rectano^ulata. Other differences arc as follows : 



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

 derasa, and darkest in rectangiilata. 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 that there is a yellowish re- 

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

 absent in rectangulata, the markings of which are bright pink. In fact, 

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

 allied to derasa, than it is to rectangutata. 



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

 band, well defined along both edges, extending uninterruptedly from apex 

 to cuter angle. In rectangulata the line is narrow, sharply dentate 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 is.
