hairs of llie second ; in the tenuile, renuirkiil)!}- long and slender, extending tar 

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

 joint. Antt!nn;e short, just lialt' as long as the ("ore wings, stout, thick at 

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

 of much the same sbape as in Aplodes, Ijut the outer side is more oblique. 

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

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

 Aplodes, originating farther out toward the onter 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 

 ornamenled with pale pustules or reddish scales, but with a dor.sal white 

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



The species of this genns may be known by the broad tVont of the 

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

 the rounded outer edge of the hind wings. The antennte 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 {Eiinemorin). The female palpi are of great length, and are much 

 as in Racheospila. 



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

 dorsal tuljercles. Plate 13, fig. 2',], is probably the larva of Synchlora e.rcur- 

 varia. The moth, copied from Aljbot'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 i.A' Rudbeckia nitlda, the food-plant. The pupa is moder- 

 ately Ihick and brown. 



The larva (plalc lo, fig. ol) of another Sijnrhlora (tig. 46) allied to 

 exct/rraila, but with the fringe of the wings red, is represented by Abbot 

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

 head, and seven pairs of slender, red, conical tuliercles, the sixth pair sitnated 

 a little Ix'hind the middle of the body, and the seventh lorming the terminal 

 pair. Tiie chry.salis is reddish-green and very slender. The food-plant is 

 Baalt a /is h all mi folia.
