Williams1 ABSTRACT Notes on 17 species of Wisconsin Cydnidae taken from specimens in the University of Wisconsin-Madison Insect Research Collection are included in this faunal list. Genera include Amnestus, Corimelaena, Cydnoides, Gal­gupha, Melanaethes, Microporus, Tominotus and Sehirus. Froeschner (1988a, b), in a Nearctic catalog, included Wisconsin records for only three species of Cydnidae (sensu Schuh and Slater 1995). These three species are marked with an asterisk in the following list of 17 Wiscon­sin Cydnidae, with data taken from specimens in the University of Wisconsin-Madison Insect Research Collection (IRC). Specimens in the IRC were determined using keys in Slater and Baranowski (1978) and then keys in Froeschner (1960) and McPherson (1982). All data presented are from adults. To assure perfect correlation with individual specimens and to avoid any possible misconstruction, plant names are presented as they appear on specimen labels. SubfamilyAmnestinae Genus Amnestus A. basidentatus Froeschner. Six specimens: late May-23 October; 1946 -1999; Dane, J ckson and Kenosha Co. Two specimens were found in native prairie sod on 6 September and 23 October. Others were collected from late May through 10 August from alfalfa, in a light trap hung on an elm tree and in an unbaited Lindgren funnel in oak/pine forest. A. pallidus Zimmer. Fourteen specimens: 15 April-29 September; 1920-1999; Dane, Grant, Iowa, Jackson, Jefferson, Kenosha, Oconto, Rock and Sauk Co. Specimens were collected from grassy litter of native prairie, from alfalfa and from tall grass. Others were swept in native prairie, were sifted from soil and grass and were f und in Berlese sampl s of grassy soil and of mossy soil. One was collected in an unbaited Lindgren funnel in oak/pine forest in late summer. A. spinifrons (Say). One specimen: 9 September 1981; Dane County.

Others were collected on Core psis, on dill, on goldenrod, on mint, on Quercus alba, on Ranunculus, on shooting-star, on sweet clover, on weeds, from tall grasses, from the forest floor, from the floor of an oak opening and from beneath dry dog feces in a sandy open area.

Notes on 17 species of Wisconsin Cydnidae taken from specimens in the

Collection 
are included in 
this faunal list. Genera include Amnestus, Corimelaena, Cydnoides, Gal­
gupha, Melanaethes, Microporus, Tominotus and Sehirus. 
Froeschner (1988a, b), in a Nearctic catalog, included Wisconsin records 
for only three species of Cydnidae (sensu Schuh and Slater 1995). These 
three 
species

in the IRC 
were determined using 
keys 
in Slater and Baranowski (1978) and then keys 
in Froeschner 
(1960) 
and McPherson (1982). All data presented are from 
adults. To assure perfect correlation with individual specimens and to avoid 
any 
possible misconstruction, 
plant names are presented as they appear on
