proach thereto in speciosa), stigmata of front and hind wings 

 similar in size, shape and color. Females without a vulvar 

 spine. 



Ischnura. Prevailing color of dorsum not metallic green. 

 Second joint of antenna otherwise colored. Pale color on 

 postero-superior part of head forming two round or cunei- 

 form postocular spots sometimes united by a transverse line. 

 M2 on the hind wings separating from Mi more often near- 

 est the third postnodal (except in /. erratica. I. cervula, I. in- 

 armata and possibly others). Males with an elevated, usually 

 bifid, dorsal process on abdominal segment 10, stigmata of 

 front and hind wings dissimilar in color, size or both (dis-

A new Erycinid from South America (Lepid.)* 

 By Levi W. Mengel, Reading, Pa. 



Chamaelimnas propinquus n. sp. 



Expanse of spread insect, 1.38 in. Male (Fig. i), upperside. An- 

 terior wings, black. A broad orange band crosses the wing trans- 

 versely, extending from the middle of the costa almost to the inner 

 angle, cutting into the lowest median nervule. The band does not 

 quite reach the costa. A sharp, triangular 

 tooth-like projection of orange reaches 

 from the transverse band, partially filling 

 the space between the second and third sub- 

 costal nervules, extending entirely to the 

 base of the wing, where the angle is quite 

 acute. There is an iridescent steel-blue 

 spot at the apex of the wing. 



Posterior wing has the basal half steel 

 blue; the outer half, black. 



The female (Fig. 2) is much the same, 

 except that the orange band is very much 

 broader and the triangular projection ex- 

 tends to the base along the costa and com- 

 pletely fills the space to the fourth sub- 

 costal nervule. The iridescent spot in the 

 apex is smaller and duller. The lower wing 

 is the same as in the male.
