hairs of the second ; in the female, remarkably long and slender, extending far 

 beyond the head ; third joint long and slender, one-half as long as the second 

 joint. Antennae short, just half as long as the fore wings, stout, thick at 

 base, well pectinated on the basal two-thirds, terminal third simple. Wings 

 of much the same shape as in Aplodes, but the outer side is more oblique. 

 The hind wings are of the same shape as in Aplodes; not angulated mesially, 

 but well rounded on the outer edge. All the venules are shorter than in 

 Aplqdes, originating farther out toward the outer edge of the wing. The 

 subcostal venules much shorter than in Aplodes. and the posterior discal 

 venule much less bent. The body is short and stout, and the abdomen is not 

 ornamented with pale pustules or reddish scales, but with a dorsal white 

 line. The front is more like Nemoria than Aplodes. Hind legs as in Aplodes. 



The species of this genus may be known by the broad front of the 

 head (not square, as in Aplodes), by the straight costa of the fine wings, and 

 the rounded outer edge of the hind wings. The antenna' are more broadly 

 pectinated than in Aplodes. The palpi differ greatly in the two sexes, so that 

 I was misled into separating the males, and regarding them as types of a dis- 

 tinct genus (Eunemoria). The female palpi are of great length, and are much 

 as in Racheospila. 



Larva. — Body cylindrical, ornamented with large conical or flap-like 

 dorsal tubercles. Plate 13, fig. 23, is probably the larva of Synchlora excur- 

 varia. The moth, copied from Abbot's MS. drawing, is represented by fig. 

 41, and agrees well with excurvaria, but may prove to be distinct. The 

 caterpillar is rather thick-bodied, with ten very large dorsal tubercles, which 

 are brown, tipped with yellow. The body is yellowish, thickly spotted and 

 slashed with brown. It bears a close resemblance in color to the brown 

 center of the flower of Rudbeckia nitida, the food-plant. The pupa is moder- 

 ately thick and brown. 



The larva (plate 13, fig. .'SI) of another Synchlora (tig. 46) allied to 

 excurvaria, but with the fringe of the wings red, is represented by Abbot 

 in a MS. drawing as quite slender and cylindrical, green, with a reddish 

 head, and seven pairs of slender, red, conical tubercles, the sixth pair situated 

 a little behind the middle of the body, and the seventh forming the terminal 

 pair. The chrysalis is reddish-green and very slender. The food-plant is 

 Baccharis halimi folia.
