TWO RECENTLY INTRODUCED SPECIES OF AMARA 
(COLEOPTERA: CARABIDAE) 
By P. J. Darlington, Jr. 
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 Jedlicka of Prague. Mr. L. L. 
Buchanan, after a comparison of specimens with the Casey 
Collection, has determined the synonymy cited. 
Amara ( s . s .) aenea (Deg.) ( devincta 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 ccelebs Hayw., to which it runs in Hayward’s key 
(Trans. American Ent. Soc. 34, 1908, pp. 49-50). In fact 
ccelebs 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 (L 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 $ are distinctly, 
although not conspicuously, pubescent within near the apex.
