Diathrausta octomaculalis, n. sp. Expanse of wing, iS mm. Palpi, head, 

 thorax, abdomen and upper side of all the wings, dark brown or nearly black with 

 greenish reflections in certain lights. There|i a fine white line on each side of the 

 face in front of the eye and three white spots on the fore wing, one across the end of 

 cell, another on the middle of the cell and the third immediately below the last on the 

 fold. The inner line is scarcely perceptable, nearly straight and crosses the wing 

 quite near the base. The outer line, which is not very well defined, starts from a 

 small white spot at the outer fourth of the costa runs down at right angles with the 

 costa, a little outside of the outer spot, then runs nearly into the spot on the fold 

 where it turn-; again and runs in a more or less wavy line to the outer third. This 

 line is continued across the hind wings with an inward curve below the cell so that 

 the lower part of it appears as a straight line extending from a white spot on the end 

 ol the cell to the anal angle. The fringes of the fore wings are black except at the 

 anal angle and below the apex where they are white. The fringes of the hind wings 

 are black at the base and white beyond. The segments of the abdomen are edged 

 with white. The underside of the wings is somewhat paler than above with the white 

 markings reproduced. The underside of the body and thorax are lighter than 

 above. Pectus and base of the palpi beneath, white.

Hydrocampa nebulosalis, n, sp. Expanse of wings, from 12 to 17 mm. Face 

 and outer end of the palpi, white. Basal part of the palpi on the outside, top of the 

 head, thorax, abdomen and upper side of all the wings, bright ocher yellow and 

 marked with white and sooty brown. The thorax is marked with transverse streaks 

 of white and the terminal edge of the abdominal segments is white. The fore wing is 

 Crossed by five white lines. The first is very near the base and indistinct ; the second 

 is near the basal fourth and is zig-zag; the third start? from near the basal third of the 

 costa, runs nearly straight towards the anal angle as far as the median vein where it 

 forms an acute angle and then runs in a somewhat waved line to the basal third of 

 the hinder margin ; the next starts from the costa a little beyond the outer fourth, 

 runs oblicpiely outward for a very short distance, then forms a wide inward curve 

 down as far as vein 3, where it turns and runs towards the base of the wing nearly to 

 the preceding line, then turns and runs to the outer third ot the hinder margin in an 

 outward curve. The outer line is sinuous and extends from the apex to a point near 

 the anal angle. The three outer lines arc edged or overlaid more or less with dark 

 sooty brown ; and the whole outer part of the wing beyond the third line is more or 

 less heavily clouded with the same, except the terminal space and an area on the 

 costa between the third and fourth lines, which extends down across the cell. Hind 

 wings white on the costa and base, and crossed by three wavy lines, the outer one of 

 which i-> white and edged on the outside with brown, the inner ones are brown and 

 edged on each side with wdiite. A yellow spot sometimes edged with brown rests on 

 the cell between these two lines and another within the inner line which does not 

 reach the costa. The inner lines sometimes fuse together as they approach the anal 

 angle. ( All the fringes are fuscous and cut with white between the veins. The 

 underside of the wings is similar to the upperside except paler.
