Orgyia leucostigma larva (red, black, white, and yellow, 
hairy tufted), 1. 
SPERMATOPHYTA. 
Rosacea. 
Fragaria sp. (fruit). 
Accepted and Refused: 
CoLEOPTERA. 
CaRABID&. 
Calosoma scrutator (metallic blue, red, and green). The 
butcherbird seemed to be staggered by the effluvium 
of one of the first Calosomas given, but devoured it. 
Later one was offered it rear end first through the wall 
of the cage; the bird ate part of the viscera, then 
refused to touch it again. However, he ate two the 
next day. In all seven were devoured. 
SILPHID#. 
Silpha inequalis (black), Al R1. 
ScaRaBAIDA. 
Trox sp., Al R1. Both the Silpha and the Trox were 
refused in presence of experimenter, but their remains 
were found in a pellet thrown up by the bird about two 
hours later. 
HYMENOPTERA. 
APINA. 
Apis mellifera, worker (brown), A 1 R1; drone, A 1. 
TA. 
Morip. 
Mus norvegicus, A2 R2. 
It is difficult to believe that a bird acting on principle would 
refuse Epicauta vittata and eat Meloe americana. Dviabrotica is eaten. 
by wild individuals of the species, and Silpha; which was both accepted 
and rejected by this bird, is a common capture. Calosomas also 
are frequently eaten by wild butcherbirds.
