Apion /rosfi Kissinger, 1 968 : 45 (holotype, Hopkinton, Mass. ; MCZ) ;<br />

O'Brien and Wibmer 1982:23.<br />

Description. Length 2.2-2.6 mm. Body moderately elongate,<br />

dark chestnut brown. Pubescence conspicuous, consisting <strong>of</strong> white,<br />

<strong>of</strong>f-white, and dark scales; scales on basal and apical regions <strong>of</strong> elytra<br />

lighter, separated by transverse bands <strong>of</strong>finer, darker scales appearing<br />

as dark band slightly below middle; scales on basal part <strong>of</strong><br />

metepisternum denser and in wider band than in apical region. Frons<br />

wider than dorsal tip <strong>of</strong> rostrum. Rostrum <strong>of</strong> male slightly curved, about<br />

L.4-1.5 times longer than pronotum; sides, in dorsal view, nearly<br />

parallel to tip, sometimes weakly expanded at antennal insertion;<br />

surface dull, minutely reticulate, with obscure punctures and sparse,<br />

scattered scales. Rostrum <strong>of</strong> female very long, 2.0-2.7 times longer than<br />

pronotum, otherwise similar to male. Antennae inserted in front <strong>of</strong> eye<br />

at distance greater than length <strong>of</strong>eye. Eyes prominent, strongly convex.<br />

Pronotum at base about 1.1 times wider than long; sides distinctly<br />

arcuate, abruptly rounded at constricted apex; disc slightly conyex,<br />

transversely impressed at base, with shallow punctures and long,<br />

narrow scales; interpuncture spaces strongly reticulate. Elytra about<br />

1.3 times longer than wide; striae moderately deep; interstriae about<br />

twice as wide as striae, convex to nearly flat, mostly finely rugose, each<br />

interstria with a few scattered, fine scales. Legs <strong>of</strong> male lacking special<br />

characters.<br />

Distribution. Nova Scotia to Ontario, south to Massachusetts,<br />

Pennsylvania, NewJersey, and Ohio. Nova Scotia: South Ohio. Ontario:<br />

Merivale. Quebec: Quebec City.<br />

Comments. This species belongs in the subgenuxkapion.Adults<br />

may be distinguished by the relatively large distance between the<br />

antennal insertion and the eye, by the evenly sloped dorsal margin <strong>of</strong> the<br />

antennal scrobe, and by the very long female rostrum. Adults have been<br />

found on flowers and in the fruit <strong>of</strong> witherod (Viburnum cq.ssinoidesL.).<br />
