-Hi JOHN B. SMITH. 



Si niie of the small examples of this species I have seen marked 

 rutila in collections ; but for that species the shape of the reniform 

 is always a good distinctive feature. The male characters are much 

 as in the allied species, except that the harpes are unusually broad, 

 the clasper is perhaps a little longer and more twisted than usual ; 

 but this may be due to the large size of the entire insect. 



Hydroecia. f'urcata n. sp., pi. 2, fig. 35, % genitalia. 



Ground color varying from straw yellow to reddish lnteous. Head and thorax 

 in the paler specimen with a rosy tinge, particularly well marked on the head, at 

 the sides of the collar and at the tips of the thoracic and abdominal tuf tings In 

 the darker specimens this tuft becomes purplish. Primaries with all the mark- 

 ings fairly evident. Basal line geminate, brownish, tending to become obscure, 

 and in the darker specimens merged into the ground color, leaving the inter- 

 vening spaces a little paler. T. a. line geminate, brownish, irregular, as a whole 

 somewhat inwardly oblique from the costa to the submediau vein, below which 

 it makes an outcurve so that the termination of the line on the internal margin 

 is almost opposite its inception on the costa. Here also the tendency is, in dark 

 specimens, to lose the lines and leave the included spaces a trifle paler. T. p. 

 line geminate, crenulate. the inner line best defined, but the outer one almost 

 equally distinct. As a whole the line is very evenly curved over the cell and 

 below that point nearly parallel with the outer margin or with only a slight 

 incurve. S. t. line irregular, outwardly dentate on the veins, somewhat lunulate 

 and marked by a preceding dusky shading, the terminal space being a little paler, 

 except where cut by the brownish veins. There is a terminal brown line, beyond 

 which the fringes are brownish or a little purplish. There is an obvious median 

 shade which is a little diffuse, outwardly oblique from the middle of the costa to 

 the median vein, where it touches the reniform, and is then inwardly oblique 

 and even to the inner margin. The orbicular is white, defined by a brownish 

 line and is somewhat irregularly oval. The claviform is elongate, a little 

 irregular, also white and with a brown outline. Between these two spots is a 

 small white dot situated just below the median vein and also with brown out- 

 lines. A small white dot is on the median vein just beyond the basal line. The 

 reniform is very large, a little constricted centrally, the lower portion consider- 

 ably broader than the upper; the center of the spot a yellowish lunule, which is 

 incompletely ringed with white, the white extending beyond the cell and cut up 

 into small spots by the brown veins which run through it. In all there are 

 seven spots varying in size and shape according to their location, which com- 

 pose the outline of the reniform. Secondaries whitish or yellowish, without 

 markings of any kinds. Beneath whitish or yellowish, immaculate. Expanse

Five specimens, all males, are before me. The insect resembles 

 very strongly the serrata of the Rocky Mountain fauna; but the 

 antennae of the male are ciliated only, the joints hardly marked. 

 The insect also resembles marginidens quite strongly and is probably 

 confused with that species in collections. It differs by the paler 

 color throughout, by the general absence of white spots in the basal
