TWO RECENTLY INTRODUCED SPECIES OF AMARA (COLEOPTERA : CARABIDAE)
Museum of Comparative Zoology
During recent years the following two species of Amara have been common in the Boston region, even on the streets of the suburbs. They are not, however, represented in the collection of the former Boston coleopterist Roland Hay- ward, whose revision of Amara was completed about 1906. This makes it practically certain that the species have been introduced since that time. Both are common European species. My identifications have been confirmed through the kindness of Mr. Arnost Jedlizka of Prague. Mr. L. L. Buchanan, after a comparison of specimens with the Casey Collection, has determined the synonymy cited. Amara (8. s.) aenea (Deg.) (devkcta Csy.) : I have seen this species not only from Boston but from Walton, New York, G. W. Herrick collector (U. S. N. M.). The type of Casey's devincta (Memoirs 8,1918,307) was from New Lon- don, Connecticut. A. aenea is similar to our western Amer- ican celebs Hayw., to which it runs in Hayward's key (Trans. American Ent. Soc. 34, 1908, pp. 49-50). In fact celebs differs from aenea (known from Europe and Sibe- ria), so far as I can see, only in its
(ccelebs) somewhat
broader and less convex form.
Amara (s. s.) familiaris (Duft.) (humilis Csy.) : Casey's specimens (1. c., 302) were from Rhode Island and Long Island. The species is, common in eastern Massachusetts (Boston, Nahant, Ipswich) and in New Hampshire (Exeter, Rumney, Mt. Washington, Connecticut Lake). It differs from all our native Amara (s. s.) in its small size (6 mm., more or less) and pale legs. It resembles some of the species of subgenus Celia, but the hind tibiae of the 8 are distinctly, although not conspicuously, pubescent within near the apex.
