space, The terminal line is dark brewn and broken. Fringes pale straw-yellow, 
mixed with brown scales. 
Hind wings white, with a brown discal spot near the middle, and a brown cross- 
line extending from the outer third of the costa to a point beyond the end of the 
median vein, thence to the origin of vein 2, where it turns and runs to the margin 
within the anal angle. This line is obliterated at the beginning and on the median 
vein, elsewhere it is wavy in its course. The terminal space is sprinkled with brown 
atoms, leaving a clear space along the outside of the cross-line, widest behind the cell 
and towards the costa. 
Fringes white, mixed with brown scales. 
Under side of body and wings white, the latter showing the markings of the upper 
side more or less clearly; fore wings sprinkled with brown through the middle and 
in the terminal space. Legs white, the fore tibiz brown on the outside. 
Described from one specimen in the National Museum, taken on the 
Argus Mountains, California, April, 1891. 
Metasia quadristrigalis nu. sp. 
Expanse of wings, 19mm. Head, thorax, and upper side of fore wings yellowish 
brown, sprinkled with dark brown atoms, giving to these parts a dark, yellowish 
brown appearance. Palpi, darker on the outside than the head, and white beneath. 
Two white lines cross each fore wing. The inner line starts from the basal fourth of* 
the costa, runs obliquely to the middle of the cell, where it turns at nearly a right 
angle and runs in a more or less zigzag course to the basal third of the hind margin. 
The outer line starts from the outer fourth of the costa, runs obliquely to a point 
nearly halfway between the end of the cell and the outer margin, thence runs to 
the outer fourth of the hind margin, curving slightly inward in itscourse. The reni- 
form spot is very slightly indicated by a few dark brown scales on the end of the 
cell. The extreme edge of the outer half of the costa is marked with white and dark 
brown alternately. Fringes slightly darker than the surface of the wings. 
Hind wings brownish, about as dark as the forewings, but without the yellowish 
tint, and with a row of faint dots along the outer edge. Under side of fore wings, 
grayish fuscous, whitish along the costa, and with four equidistant, dark brown spots 
on the outer half, The outer line is faintly indicated in dark brown, and there is a 
terminal row of dark dots. Underside of hind wings much lighter, coarsely sprinkled 
with brown, especially on the costal half, and a terminal row of brown dots and an 
outer curved cross-line starting from a brown spot on the outer third of the costa. 
Described from one specimen in the National Museum, taken on the 
Argus Mountains, California, April, 1891. 
ENTOMOLOGICAL MEMORANDA FOR 1893. 
By Mary E. MuRTFELDT, Kirkwood, Mo. 
Disappearance of the Web-worm Tiger around St. Lowis.—Among the 
insects which I, in vain, endeavored to collect during the past season 
was the valiant little Carabid Plochionus timidus. From dozens of 
Web-worm nests examined, both of the first and second broods, not a 
larva could be obtained. The result of the disappearance—temporary, 
it is to be hoped—of this important check on the development of 
* Hyphantria cunea was noticeable in the unusual numbers of the second 
brood. I am at a loss to what to attribute the scarcity of the Carabid
