who wish to obtain these volumes, should send in their namesto 
the Secretary, Rev. T. Wiltshire, 25 Granville Park, Lewisham, 
London, S. E., England. We regard the publication of these — 
sketches and descriptions as a great boon to American entomol- 
ogists, in default of good figures of native larvæ.— —At the meet- 
ing of the London Entomological Society, October 3, Mr. Wailly 
exhibited a Samia allied to S. cecropia, and possibly a hybrid be- 
tween it and some other (unknown) species. “ The Butterflies 
of Maine” by Professor C. H. Fernald, is rich in new facts regard- 
ing the distribution and habits of these insects. Itis rather start- 
ling to read of the occurrence of Chionobas jutta at Orono and of 
Terias lisa in the Isle of Shoals, Euptoieta claudia near Portland, 
and Junonia coenia near Bangor. Sixty-nine species are enumer- 
ated.—— Dr. Heylaerts has nearly ready for publication a mono- 
graph of the Psychides of the world. In the Compte-rendu of 
the Entomological Society of Belgium, besides notes on European 
species, he describes four new species from the Argentine Repub- 
five of those of P. turnus, five of P. troilus and four of Z. rAr 
and five of P. philenor ; of the Nymphalines four stages of Welt 
tæa phaëton, three of Melitea marcia, three of M. nycteis, two ° 
Argynnis myrina. The paper closes with some general ares 
it will greatly interest American lepidopterists. The sket

ZOOLOGY. 
Tue LIFE-HISTORY oF THaLassEMa.—Mr. H. W. Conn s 
ry of Jo 
Hopkins University (Vol, 111, No. 1), an abstract of his rese dee 
on the early stages of tbis Echiurid worm. The T name 
i i it unde 
observation he regards as new, and mentions it a a light yel- 
low preoral lobe. It has the habit of seizing upon emp $ of 
dollars and making its home in them. It enters-the cons 
the shell while very small, but once within it grows to 4 
erable size, and remains the rest of its life a prisoner. 
The most important points observed are the following : 
I. The origin of the ova and spermatozoa as ept eserva- 
toneal cells ; their growth in the body-cavity, and t seine’ 
tion in a sexually mature condition in the sexual pou hythm pè 
~ 2. Protrusion of two. polar globules exhibiting 2 T 
cisely similar to that of the segmenting ova.
