come at first or second hand from me. The very poor descriptions in 
the Lepid. Het. have not as yet improved our knowledge of our species, 
except to the extent of giving us three very doubtful forms as new, the 
best of which (C. obscura) I thought might be Guenee’s indicated var. of 
insolabilis, and so informed Mr. Strecker, who sent me a specimen for 
examination, accompanied by an epistolary threat that if I did not give 
him the name of it within a certain time, he would “ describe it as new.”

MISCELLANEOUS. 
AN AQUATIC BOMBYCID Motu.—Mr. Bar, of Cayenne, has forwarded 
to the Entomological Society of France, descriptions and specimens of 
the various stages of an interesting Bombycid. The larva lives under 
stones in streams and rises to the surface for transformation. The cocoons. 
are found in clusters floating on the water. Aquatic caterpillars have 
hithert> been known only in the lower families of Lepidoptera.— American 
Naturalist. 
MODE OF EGG-LAYING OF AGRION.—Mr. G. W. Dunn writes us that 
while collecting at Santa Cruz, California, he observed a species of Agrion 
(as we find the insect to be) ‘flying about the water united, male and 
female. The female would light on a spear of grass growing in the water ; 
the male would then let go, and the female go down the grass twelve or 
fifteen inches under water and deposit her eggs.” American Naturalist.
