A summary of biological information on Dennstaedtia punctilobula (Michx.) Moore, hay-scented fern, is presented. It has a native perennial herbaceous species of North America which has its center of distribution in the Appalachian region. In Canada it is found from the East Coast to Ontario. It is a weed in native lowbush blueberry fields, upland pastures and roadsides, particularly in the eastern parts of its range, where it forms dense colonies.

Although the interest in shell middens in North America is often traced to reports of the discoveries in Danish kjoekkenmoeddings in the mid-nineteenth century, extensive shell midden studies were already occurring on the East Coast by that time. This article reviews selected examples of this early work done by geologists and naturalists, which served as a foundation for shell midden studies by archaeologists after the Civil War.

Anoplius tenuicornis (Tournier) is a holarctic species with a broad distribution both in Europe (Wolf 1967) and North America (Wasbauer and Kimsey 1985). Despite the widespread occurrence of the species, individuals are not frequently encountered, so it is not surprising that biological information on it has not been available for North America and very little for Europe. Richards and Hamm (1939) gave two fragmentary reports of some significance on A. tenuicornis in England, reported as A. piliventris (Morawitz). In one case, cocoons of the wasp were found in dead thistle stems. In the other, an old burrow of Ectemnius continuus (Fabricius) (Sphecidae) (reported as Solenius) in rotten wood contained a series of wasp cocoons and fragments of clubionid spiders, the presumed prey.

Abstract This article describes the morphology, morphometrics, and geographical distribution of the fish parasite Glugea heraldi infecting fish of the family Syngnathidae (pipefish, seadragons and seahorses) in brackish waters of subtropical east coast of North America. This parasite can only be found in New York and Florida.

Biological information is given for the following four species of Oxycerini (Diptera: Stratiomyidae) occurring in madicolous habitats of eastern North America: Euparyphus stigmaticalis Loew, Euparyphus brevicornis Loew, Caloparyphus greylockensis (Johnson), and Caloparyphus tetraspilus (Loew). Descriptions of immature and adult stages are included for each species, and a key to the immature stages is given.
