168 DRAGONFLIES OF NORTH AMERICA 
125. Macromia pacifica Hagen 
Hag. 61, p. 184: Mtk. Cat. p. 121. 
Syn: flavipennis Walsh 
Length 70 mm. Expanse 94 mm. Wis., Ind., Tex., Calif. 
A fine western species, with yellow costal wing margin, and double row of 
spots on the abdomen. Face greenish yellow across the postclypeus and dull 
yellow on the labrum. Top of frons pale, scarcely showing the outline of the four 
usual spots. The pale stripes of the front of the thorax are well developed, 
parallel sided, and reach upward nearly to the crest. Side stripes broad and well 
defined, with an inferior pale stripe on the hind margin of the thorax. Legs 
black. Wings hyaline, with yellow costa, and blackish stigma. Pale markings 
of the top of the abdomen divided on the median line on segments 2 to 8; on 2, 
an elongate and rather wide transverse band; on the other segments spots, largest 
as usual on 7. Segments 9, 10 and appendages black. 
Williamson, who has observed this species at Bluffton, Indiana, says 
(09, p. 386) that it is readily recognized at some distance on the wing, 
and that “In flight one gets the impression of an insect largely yellow 
in color.” 
126. Macromia annulata Hagen 
Hag. 61, p. 183: Mtk. Cat. p. 120. 
Length 68 mm. Expanse 95 mm. Carolina, Tex., Ill. 
A rather pale species with whitish face and yellow costa. The vertex is pale. 
The pale stripes of the front of the thorax are well developed, parallel sided, and 
reach upward nearly to the crest. The hind margin of the thorax also is yellow 
lined beneath. Legs black with bases of the femora paler. Wings hyaline with 
yellow costa and brown stigma. Pale markings of the abdomen continuous 
across the middorsal line, there is a narrow band across segment 2, a broad spot 
on 7 and shorter spots on 3 to 6 and on 8. Segments 9, 10 and appendages, 
blackish. 
127. Macromia magnifica McLachlan 
McL. ’74, p. 22: Mtk. Cat. p. 121: Kndy. ’15, p. 313. 
Length 70 mm. Expanse 96 mm. Calif., Ariz. 
A fine brownish western species rather brightly marked with yellow and with 
venation rather more open than in the other species. Face with the usual two 
pale cross bands and with the top of the frons and the vertex yellowish. Stripes 
on the front of the thorax broad, and reaching well up toward the crest. Legs 
blackish. Wings hyaline; costa yellow; stigma brown. Pale marks of the dorsum 
of the abdomen undivided except on the 2nd segment and rather broad on the 
succeeding segments; there are represented by narrow transverse basal lines 
on 9 and 10. Appendages brown. 
Kennedy (15, p. 313) reports interesting observations on this spe- 
cies, made by him on Satus Creek, Umatilla flats, Oregon, from which
