12 ( 1 1 ) . Siignia narrower, usualh- three or more times as long as wide 13 



13 (14). Wings raised, when at rest. Inner end of quadrangle only one-tilth as 

 long as the inferior side. The prothorax with three scallops postericjrK , the mid- 

 dle one of which is the longest. Euroix> to Madagascar, New duinea, and New 

 Caledonia. (Fig. 42.) Sympycna Chari)eniier, 1840 



14 (13). Wings held horizontalK, when at rest . The i)rothora\ not as aho\e 15 



15 (16). The sectors of the arculus arising toward the middle, M.i about one-half of 

 the wa\' down; hence the ciuadrangle is narrow with the inner end between one- 

 fourth and one-fifth as wide as the inferior side is long. The ([uadrangle in the 

 hind wing has a distinctly longer upper side than does that of the fore wing. 

 The upper and lower sides are almost parallel. A genus from .Australia and sur- 

 rounding islands. (Fig. 43.) Austrolestes TilKard, 1913 



16 (15). The sectors of the arculus arising nearer its u[)per end, Mi.ihdut one-third 

 of the way down, hence the inner end of the quadrangle is from one-third to 

 one-fourth of the length of the inferior side. The cjuadrangle of the front and 

 hind wings essentiall\- alike and triangular in shape l)ecause ol the narrow- 

 ing distalh-. Cosmopolitan, excejit not in Australia. (I'ig. 44.)

1 (6). Secondary- sectors numerous; two or more rows of cells between M,.. and M2 

 for some distance. Mr^i forking at more than one-hall of the distance trom the 

 subnodus to the tiyj of the wing. Cuj short, ending at the level ot less than one- 

 half the distance from the fork of Mi-j to the tip of the wing. Cui with many 

 forks; several to many cells between Cu2and the i)osterior wing margin 2 



2 (5). Quadrangle not crossed; about five times as long as wide. Xo cross-\ein in 

 the subquadrangle. M.A before the le\el of the subnodus. M1-2 forking be- 

 yond the half-way point between the subncKius and the tij) of the wing 3 



3 (4). The nodus at one-sixth of the wing length; M2 arched forward under the 

 stigma so as to make a sharp bend. M forks under the inner end of the stig- 

 matic area, at about fifteen cells from the margin of the wing; Cui forks many 

 cells from the wing-margin. Mexico to C.uatemala. (Fig. 46.) 



Megaloprepus Rambur, 1842 



4 (3). The nodus at one-fifth of the wing length; M^ not so strongl\- arched. M.3 

 forks about five cells from the wing margin or not at all. Cui forks about five 

 cells from the wing margin. Colombia to Brazil and Fcuador. (Fig. 47.)

5 (2). The (luadrangle with two or three cross-veins, sexeral in the sub(iuadrangle, 

 some of which line up with tho.se in the ([uadrangie. M.A in the hind-wing es- 

 pecially, is at the level of the subnodus. .M1+2 forking at about half wa\- between 

 the subnodus and the wing tip. Peru and Ecuador. (Fig. 48.)
