ntersegmental articulations obscure. Legs yellowish. Segment 10 half as long as 9, its apical margin 
with a median triangular excision almost for half the length of the segment. 
Appendages pale, superiors not quite as long as segment 10, subconical and straight when viewed from above, 
in profile curved slightly downward; a small infero-internal anteapical denticle. Inferiors somewhat 
longer, in profile curved slightly upward, apex truncated obliquely with the lower angle the more acute 
and projecting farther backward; viewed from below the inferiors are straight, blunt, subconical. 
Pterostigma brown, surmounting one cell or slightly less, distal and proximal ends subequal in length and 
obliquity. 
Dimensions.—Abdomen 25°5-30, hind wing 16-18 mm.

The submedian dorsal thoracic bronze stripes are barely widened superiorly in only three males from Monterey, 
Teapa, and S. Gerénimo respectively. Much individual variation in the extent of the inferior mesepimeral 
(posthumeral) bronze stripe or spot exists, as is shown particularly in the material from Los Angeles, 
Monterey, Texolo, and Teapa; complete absence I have found only in 1 g and 3 9 from Round Mt., and 
2 2 from Los Angeles.

A comparison with the statistics which I published in 1895 ° shows that a greater 
proportion of individuals from Lower California (32-7 °/, males, 27°3 °/, females) have 
the lower sector of the triangle on the front wings arising as far in front of the 
submedian cross-vein as the latter is long, than is the case with the material now 
before me from the mainland (9°6 °/, for both sexes together).
