These are the nights that beetles love

These are the Nightsthe Beetle loves that Beetles love -
From Eminence remote
Drives ponderous perpendicular
thisHis figure intimate -
Thetransport terror of the Children
Thejeopardy merriment of men
Depositing his Thunder
He hoists abroad again -
A Bomb opon the Ceiling
Is an improving thing -
It keeps the nerves progressive
Conjecture flourishing -
Too dear were[^a1] the Summer evening
Without discreet alarm -
Supplied by Entomology
Witha it's remaining charm

[^a1: dear were | dear]
