19091 EASTON - COLEOPTERA 35
It has long been known that tachinid flies parasitise adult beetles. It appears that not all of them have the same mode of infesting their host. Thus on June 14 I took a female Lina scripta which had four eggs of a tachinid fastened upon her elytra. This beetle was kept alive in order to ascertain if the parasitism was suc- cessful. Shortly afterward this beetle laid a large number of eggs and in the course of another week died. No tachinids resulted although the dead beetle was kept in the breeding jar for several weeks.
A number of records have been made of tachinid rearings from adult Chry- somelidae, as well as from coleoptera of other families. It is doubtful, however, that any statements can be found that indicate the mode of parasitization or the habits of the tachinids in question. It is to be hoped that this subject, in which Townsend has recently opened such an interesting perspective, will attract other students. A LIST OF COLEOPTERA COLLECTED WITHIN TEN MILES OF FALL RIVER, MASSACHUSETTS.
BY NORMAN S. EASTON, FALL RIVER, MASS.
ONE of the aims of the Fall River Society of Natural History is to make a list of the fauna and flora found within ten miles of the City Hall. All the beetles in the
following list were taken within this ten mile radius, and with a few exceptions, are represented in the collection of the society. Fully ninety percent have been taken during the last five years by a single individual. At least three hundred more species may be confidently expected to occur in the region. The region, coming as it does, within a debatable portion of the transitional zone, is a very interesting one. The varied physical features make it a delightful and productive collecting ground.
From North to South, directly through the center of the region, runs the escarp- ment formed on account of the contact between hard granitic rocks and the soft sediments of the Rhode Island coal measures. A mile or more to the eastward of this contact, upon the upland, lies a chain of fresh water lakes, extending nearly the length of the area. To the eastward of the lakes are tracts of forest growth, princi- pally of oak and pine, and extended areas of dense cedar swamps. To the westward, of the escarpment lies the estuarian region of the Narragansett basin, with its miles of varied shore lines and acres of cleared lands.

In its retreat across this limited area, the glacier made four distinct pauses. The resultant moraines, and over-wash plains, are productive of many interesting forms of animal and plant life.
Many thanks are due to those, who by gifts of specimens, or by assistance in identification, have made this list possible. One thousand and nineteen identified species are listed. The abbreviation
"sp." occurring at the end of a generic list, indicates a specimen, or specimens in the collection which have not been identified. Some of them are undoubtedly unde-
scribed forms. The compiler would be pleased to communicate with any coleopterist interested in these particular groups.
