About ten specimens were collected in Oak- land, California, by Prof. Josua Lindahl. This species is ver}- similar to the type and onl}^ described species of the genus, Actonhvus elUptlcii>< Harger, but differs in having the sur- face of the body covered with low tubercles; in having the three lobes of the head anteriorly truncate, while in A. ellipticus the median one is acutely pointed, the lateral ones rounded; in having the fourth and fifth articles of the peduncle of the antenna^ subequal, and the sec- ond article of the flagellum longest, the terminal article not minute, but as long as the preceding one; in having the post-lateral angles of the first thoracic segment produced in acute proc- esses, and in having the sixth or terminal segment of the abdomen triangular rather than rounded. This species is named in honor of Prof. Josua Lindahl, from whom the specimens were Fig. ri79.â(.:n DAHLI. â 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 National Museum; Smithsonian Institution; United States.
