246 REPORT OF COMMISSIONER OF FISIZ AND FISHERIES. [540] 
Muscinz.—Larve of an undetermined fly. (p. 415.) 
This larva was found living beneath the surface of the sand, at low- 
water mark, on the shore of Great Egg Harbor, at Beesley’s Point, New 
Jersey, April 28, 1871. (A. Hi. V.) The same larva, or an allied spe- 
cies, was found May 5, under stones below high-water mark. “Specimens 
were brought tome from New Jersey, and kept living in sea-water for 
some time. The following description is from the living specimens: 
Body white, long, slender, cylindrical, tapering gradually from the penul- 
penultimate segment toward the head; thirteen segments, counting the 
head as one. Segments smooth, thickened at the hinder edge, the su- 
tures being distinct; tegument very thin and transparent, allowing the 
viscera to be easily distinguished. The terminal segment of the body is 
conical; seen from beneath it is nearly a fourth Jonger than broad, the 
end subacute and deeply cleft by a furrow which diminishes in size and 
depth to beyond the middle of the segment, where it fades out. This 
conical extension is flattened vertically above; from the middle of the 
same ring project the supra-anal, conical, fleshy tubercles, one-fourth the 
length of the entire ring, which give rise to two main trachee running 
to the head, and which separate and close together at the will of the 
animal. When extended the prothoracic ring is considerably longer 
than the others. Head one-third as large as prothorax, and a little 
more than half as wide. Length, 9™™. 
I cannot detect any spiracles on either of the thoracic rings. The 
trachex are not nearly so regular as in the larve of the Anthomyia ce- 
parum, with living specimens of which I placed it side by side; head 
much the same, showing it may be of this family. Minute antenne 
present; no traces of them in Anthomyia, and their presence throws 
a doubt whether it be a muscid.”—A. S. P. 
ERISTALIS, species undetermined. 
One large-sized larva was found in Vineyard Sound among alg in 
April, by Mr. Vinal N. Edwards. 
EPHYDRA, species undetermined. (p. 466.)

Shores of Narragansett Bay, puparium found under sea-weeds by 
Dr. T. @Orexmieul. According to Dr. Packard, “scarcely distinguish- 
able from FH. halophila Packard, which lives in salt brine at the salt- 
works in Gallatin County, Illinois.” 
COLEOPTERA.” 
A number of species of tiger-beetles (Cicindelu) are common on the 
sandy shores and beaches just above high-water mark, and some of 
them are seldom found away from the sea- -shore, while others are also 
found far inland. The larvie of some of these, and perhaps of all, live 
below high water, but this has not yet been observed in the case of wepéral 
“The Coleoptera were mostly determined by Dr. George H. Horn.
