HYDRGECIA STRAMENTOSA, GUEN. 



Plate 2, Fig. 5, nearly twice natural size. — I here copy in full the 

 description of the species, as given by Dr. J. B. Smith in his recent 

 revision of the genus Hydroecia, in the Transactions of the American 

 Entomological Society, Vol. 26, May, 1899. Also his remarks on and 

 about this interesting species.

 Collar wilh a narrow brown line above the middle, the tip distinctly 

 smoky, as are also the tips of the thoracic tuftings. Edges of the 

 patagiae marked with smoky brown, vv'hich is particularly well marked at 

 tip. Sometimes the entire thorax is darker, and in such cases the con- 

 trasts between the ground colour and the markings just described are not 

 great. The abdominal tuftings at the base are also dark. The primaries 

 have a reddish shade over the costal region extending to the tip. The 

 outer portion of the median space is distinctly darker, olivaceous, and 

 stands out quite evidently from the rest of the wing. The basal line is! 

 geminate, fairly well marked on the costa, then broken and only marked 

 as a spot below that point. T. a. line geminate, the inner line scarcely 

 traceable below the cell : as a whole it is nearly upright, but is inwardly 

 curved through the cell and has a very feeble outcurve below that point. 

 T. p. line very even, rather abruptly bent on the costa, a little outcurved 

 over the reniform, and then evenly oblique inwardly to the inner margin. 

 S. t. line irregular, brownish or smoky, marked by a preceding shade in
