many plants which are known to be native both there and in 
America, and it is notorious that maritime species are wide 
ranging. It is not easy to see, however, how our many enthu- 
siastic local collectors, past and present, could have entirely 
missed the species, though perhaps the facts that the spring 
flight, so called, is exceptionally early, that the insect is less 
conspicuous later in the year, and that it is flightless and not apt 
to straggle into more frequented regions may have contributed 
to its invisibility. The larva, of course, must inhabit the same 
region as the adult, and must be buried in the sand to escape the 
heat of the sun, so that it is even less likely to be discovered or 
transported than the adult. Several other beetles more or less 
common at Ipswich are poorly represented in local collections, 
and the few representatives are usually from localities to the 
south. If it can be shown that arenaria exists at more northern 
stations and if it does not turn up further south, we shall be able 
to see how it at least might have been overlooked in the past. 
Botanical evidence indicates that, if the species is naturally of 
transatlantic distribution, it should occur in the Gulf of St. 
Lawrence region. 
The determination of the Mass, specimens depends on com- 
parison with one from Europe in the Museum of Comparative 
Zoology and on reference to the literature. There seems to be 
no other European species with which the present one could well 
be confused. 
In addition to A. arenaria, five species of the genus occur in 
New England, one of which appears to be at present unrecorded. 
A. blanchardi Horn, spissipes Lee., opifex Horn, and rufescens 
Horn are all found in eastern Mass., while the last two have been 
taken in central N. H. as well. A single specimen of A. lacustris 
Lee. was taken at Paris, Me., July 9, 1915, by Mr. C. A. Frost, 
and has been compared with the type. Another unique, also of 
lacustris, but leaning a little toward cylindrica Esch. , was taken 
by the writer under a stone in Tuckerman’s Ravine, Mt. Wash- 
ington, N. H., Sept. 10, 1926, at about 4,000 ft. elevation. For 
the final determination of this specimen I am indebted to Mr. 
H. C. Fall. The previously known range of lacustris includes 
Nfld. and Mich.
