Mr. J. D. Sherman, Jr., of Peekskill, N. Y., sent the follow- 
ing communication : 
COLEOPTEROLOGICAL NOTES FOR THE YEAR 1886. Cychrus stenostomus 
was found several times under fungi where, I suppose, it had stationed 
itself in order to feed upon the insects inhabiting the fungus. 
Amara impuncticollis is found on Lepidtum virginicum during the 
warmer parts of the day in May; whether or not it feeds on the plant 
I am not certain. 
Lebia ptilckella was found under stones on May 18 and October 8. 
Cercyon prcetextatum and Silpha americana were found in fungi. 
The following Coccinellidce are found on Asclepias cornuti : Hippo- 
damia glacialis, convergens, parenthesis, Coccinella noi'emnotata, Adalia 
bipunctata, Brachyacantha ursina. 
Dermestes caninus in a vacated bird's nest. 
Cryptorhopalum triste, common on Taraxacum dens-leonis, in May. 
Cryptarcha strigata, in fungi where Pocadius helvolus is common, also 
on bruised pears, in September. 
Tenebrioides corticalis and Adelocera discoidea common under the bark 
of dead Pitch pines (Pinus rigida}, where, on February 10, I secured a 
single specimen of Dicerca punctulata. 
Acmceodera culta common on Taraxacum in May. 
Oxyomus porcatus common in dried horse manure in April. 
Both sexes of Geotrupes splendidus I found in a smooth-surfaced, nearly 
round cavity situated at the bottom of a winding hole some three or four 
inches deep, which communicated with the interior of the stem of a fungus ; 
with them I found a pupa, which no doubt belongs to this species. 
The species of Trox fly in the hot sunshine in April (T. monachus and 
unistriatus), are attracted by light at night (T. terrestrtsa.r\d unistriatus), 
and are found in filth (T. terrestris, or allied species). 
Macrodactylus subspinosus was unusually uncommon on the rose, doing 
but little damage; nevertheless it was as abundant as ever on the Ox-eye 
daisy. 
Molorchus bimaculatus, common on Viburnum prunifolium during the 
latter part of May. 
Colaspis brunnea abundant on Ambrosia artemisicefolia. 
Mr. Smith called attention to a peculiarity observed by him 
in the antenna of Cressonia juglandis. They have in the male 
two branches to each side of each joint, precisely as in the Satur- 
niidaj. This feature is unique in the Sphingidae of North America ; 
nor did he know of its occurrence in exotic genera. He empha- 
sized the relation of the Smerinthids to the Bombycids, even
