an inch long. The insects, however, were very stupid. On the — 
11th, the cherry blossomed, and on the 9th, the peach. On the 11th, — 
I saw several specimens of the Pieris rapae, the new cabbage but- _ 
terfly. Since ao I regret to say, this fearful pest has appeared 
in alarming numbers. On the 28th, I saw the first specimen 
of Colias Philodice, the sulphur butterfly. The plow is turning — 
up now (May 10) great quantities of chrysalids of the Carolina — 
Sphinx, the dreaded potato worm. — S. Locxwoon, Freehold, N. J. — 
A Srrawserry Cur Worm.—Mr. Hooper, of Marblehead, 
brought us the full-sized larvie of the Dorbug, Lachnosterna fusca, 
about the middle of June, at which time they were cutting off his 
strawberry plants to considerable extent. 
Correction.—On page 714, Vol. iv of the Naruraxist, it is 
stated that the Euphonia elegantissima in the Vassar Cabinet has 
a bright yellow forehead. This is true only of the female, and the 
specimen is very likely young. So that the discrepancy exists — 
only in the throat of the male.—James ORTON. 
Fisnes or tae Ampyracu River.—At a recent meeting of the 
Academy of Natural Sciences of Philadelphia, Prof. Cope read a 
paper on the ichthyology of the Ambyiacu River, a tributary of 
the Amazon, in Eastern Equador. The results of the investigation 
were summed up as follows. The fishes in the collection examined 
were referred to nine families, fifty-one genera, and seventy-five 
species, distributed as follows: 
Genera. Species. Genera. Species. 
Tetraodontide, ł 1 Erythrinidæ, 2 2 
Chromididæ, 7 15 Characinidæ, 21 29 
Clupeidæ, 1 1 Siluridw, 15 d 
Osteoglossidæ, 1 1  Symbranchidæ, 1 1 
ý 2 3 
Forty-seven of the above species, and nine of the’ genera are 
new to Science, and are referable to the following families: 
Genera, Species. Genera. Species. 
Chromidida, 0 9  Characinidæ, 3 16 
* Erythrinide, 0 1 Siluridw, 6 20 
The general character of this list is that of any other part of 
the Amazon basin, presenting local peculiarities in peculiar spe 
cies and in genera not found in the Lower Amazon. Such genera 
among Characinide are Triportheus, Megalobrycon, tier 
Tyuanodectes and Stethaprion ; among Siluride, Dianema, Brochis, —
