GEOMETRID NOTES— DESCRIPTION OF A 

 NEW VARIETY. 



BY L. W. SWETT, BOSTON, MASS. 



Hydriomena speciosata Pack., var. ameliata, n. var. 



Expanse 3i-33 mm. Palpi long and blackish; head and 

 thorax greenish; abdomen light ashen. A narrow black bar at 

 base of antennse. Fore wings olive green, with a broad white 

 mesial band. Base of wings blackish, with possibly the beginning 

 of a black line; between base and first line of mesial band olive 

 green, then another olive green space to the broad irregular black 

 band, then olive green to the intra-discal band. The three irreg- 

 ular lines of the mesial band are very striking; the outer one 

 nearest the discal dot projects outward on median vein, almost 

 touching the dot, and is irregular on the veins. Beyond, the 

 mesial space is greenish white, giving the insect a striking appear- 

 ance. In some respects it resembles certain varieties of H, 

 aiUumnalis that I have seen from Germany. The extra-discal line 

 is very prominent on the costa and then runs irregularly in dashes 

 across to the inner margin. Half-way between tip of wing and extra- 

 discal line is a broad triangular black spot, which appears to be a 

 broken line running in spots on the veins across the wing. A broad 

 apical black dash. Fringe black and white checkered. Hind wings 

 dark ashen brown with a pale checkered fringe. Wings beneath 

 dark brown, with markings of upper side showing through. 



This is the white-banded form that we should expect to find, 

 according to my colour-scheme (vide p. 63), and I should not 

 have described it were it not for its similarity to certain varieties of 

 H. autiimnalis, from which it can be distinguished by the long palpi. 



Type.~l 9, Victoria, B. C., July 7, 1914. From Mr. E. H.
