We have already shown (antea, p. 313) that virgaureae is the type 

 of Heodes, since Dalman cited this species alone in his generic 

 synopsis (p. 63). Scudder's action, therefore, in fixing the type of 

 Heodes as phlaeas, was ultra vires, and we, therefore, found it neces- 

 sary to create Rumicia for phlaeas (Ent. Rec, xviii., p. 131). Scudder 

 gives an extremely detailed diagnosis of the genus under the name 

 Heodes, his description (Butts. New England, ii., pp. 990-993) reading 

 as follows : 



Imago. — Head moderately small, densely clothed with scales, which are elevated 

 to high tufts behind the antennae, and furnished also with numerous hairs, above 

 very long and arching forward, behind longest and downward, in front rather long, 

 diminishing in length downward. Front flat, above a very little sunken down the 

 middle, and, at the upper extremity, a distinct, narrow, rather shallow, longitudinal 

 groove; on the lower two-thirds, a little full clown the middle, at the bottom slightly 

 tumid, barely surpassing at a single point the front of the eyes ; less than half as 

 high again as broad, of the width of the eyes as seen in front ; upper border not 

 raised, the corners considerably hollowed in front of the antennae; lower border 

 rather broadly rounded, the sides straight. Vertex scarcely elevated in the middle, 

 laterally buttressing the antennae, well separated from the occiput by a broad, 

 pretty deep, transverse, nearly straight sulcation, deepest in little pits, in the 

 middle and behind the antennae ; occiput slightly but broadly sulcated along the 

 middle longitudinally. Eyes not very large nor full, naked. Antennae inserted 

 with their posterior edge in the middle of the summit, separated from each other 

 by a space, equal to the width of the second antennal joint ; half as long again as 

 the abdomen, composed of 31 joints, of which 12 form the strongly depressed, 

 elongated club, which is about three times as broad as the stalk, four times as long 

 as broad, the first four or five joints increasing very gradually in size, beyond 

 which the club is equal and terminates by the rapidly decreasing size of the last 

 two or three joints, which form a very short but pointed cone. Palpi very slender, 

 rather less than half as long again as the eye, the apical joint fully half the length 

 of the penultimate, clothed only with recumbent scales, while the rest are 

 densely clothed with erect scales, much the longest beneath and thinly fringed 

 below with long straight hairs projecting forward and upward. Patagia compara 

 tively broad and oval at base, the posterior half forming an equal, slender, straight, 

 very bluntly-pointed lobe, scarcely one-third as wide as the base ; the whole is 

 fully three times as long as broad, the inner border slightly hollowed just before 

 the middle, the outer deeply, at the base of the posterior lobe. Forewings three- 

 fifths as long again as broad, the costal margin bent and slightly convex in the 

 middle of the basal third, beyond very nearly straight, the tip scarcely curved 

 downward, the outer angle abrupt, but rounded off ; outer border slightly and 

 regularly curved, inclining at an angle of about 75° to the costal margin ; inner 

 margin scarcely hollowed and angulated at the middle, the outer angle rounded off. 

 Costal nervure terminating at the tip of the cell ; subcostal with three superior 

 branches ; the first arising at the middle of the outer four-fifths of the cell ; the 

 second midway between the origin of the former and the apex of the cell ; the 

 third at, or barely before, the apex of the cell, forking midway between the base of 

 the nervule and the end of its upper branch ; cross veins transverse, obsolete,
