Thompson). Family BOMBYLIID^E. Fig. 21. Epacmus nitidus Cole, n. sp. Drawing of holotype. The "bee-flies" are usually more or less covered with fur- like hair and look less like bees than some other flies; one group is furnished with a long proboscis. During the spring and summer they are often seen hovering in the air. They are flower feeders and creatures of the sunshine. Their flight is very quick, but consists of short dashes, and they are often seen resting on the ground or on low plants in the sun. The larvae are parasitic, predaceous, or inquilinous. Some are decidedly beneficial, being parasitic on injurious species. 243. Spogostylum anale (Say) Forest Grove, IX-15 (Thompson and Cole). A few females were taken along Gale's Creek; the males, with num- bers of other insects, were flying around some small pine trees in the afternoon 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 Cole, Frank R.
