(Davis). THE GENUS PSOROPHORA. But one species, P. cillatx, of the genus Psorophora is known in the United States. This is well illustrated in the accompanying figure (tig. 20). Although this insect, as indicated in the synoptic. KiG. 20.—Psoroplwra cUiata: Female—enlarged (original). tables, is really yellowish in color, yet the general effect when one glances at it, or sees it flying, is that it is very dark, black. The wings are not really spotted or infuscated, but the ver}- numerous dark scales on the main veins make the wings appear dark. They are when seen in certain lights prismatic in color effect. The palpi of the female are nearly half as long as the beak, and the beak itself. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
