Excerpt: ...yet found in Minnesota are the following: CaUipterus mucidus Fitch, a doubtful species. CaUipterus castanese. Fitch, on the under side of the leaves of chestnut. CaUipterus punctaius Monell, on the under side of the leaves of Quercus bicolor. CaUipterus hyalinus Monell, on the under side of leaves of Quercus imbricaria. CaUipterus earya; Monell, on leaves of walnut, hickory and pecan. CaUipterus quercicola Monell, on oak. CaUipterus trifolii Monell, on clover leaves. Genus MONELLIA n. g. Antennae longer than the body, on no frontal tubercles. Eyes pale red; ocelli present. Beak very short. Thorax low and flat; prothorax nearly as large as thorax proper. Wings held horizontal in repose; venation as in CaUipterus. Honey-tubes not obvious. Style short, enlarged at apex. Small and delicate insects of very pale color and a strongly depressed body. Distinguished from the foregoing genus by the horizontal position of the wings when at rest, and by the much developed prothorax. Inhabits similar to Drepanosiphum, and like it, the oiviparous female appears always to acquire wings before producing living young. The genus is named in honor of Mr. Monell, who has done so much towards our knowledge of the Aphididae of North America, and especially in the genus Callipterus. 1. Monellia caryella (Fitch).
