Remarks. Shortly after the appearance of the description of 
Townsend’s cruciata in 1918, Collin wrote to Aldrich suggesting 
that xanthorrhina Bigot might be an older name for the species, 
and that Townsend’s description of cruciata exactly fitted the 
type of Bigot’s xanthorrhina. Aldrich hesitated to adopt the 
name of xanthorrhina for this species because of the difference 
in the localities given. But in 1929 he compared specimens of 
the Peruvian cruciata with the two Bigot types of xanthorrhina 
from Mexico and concluded that they were the same. 
Aldrich saw the types of bequaerts Séguy and decrepita Séguy 
in Paris in 1929, indicating in his notes that they were this 
species. 
It is interesting to note that no males of this species have been 
in collections seen by me. Notwithstanding the fact that I made 
extensive collections through Central and South American coun- 
tries, no specimens of this species were ever found. It is possible 
that some of the specimens included in this paper under another 
name may prove to be males of xanthorrhina. Aldrich’s identi- 
fication of the type of decrepita Séguy as this species would ap- 
pear to indicate that the male is essentially like the female. 
Brauer mentioned the manuscript name Mesembrinella 
chrysorhea Moritz in his 1895 paper, the specimens being from 
Venezuela. The name was never published by Moritz, and 
Brauer must assume the responsibility for the name since his 
was the first published description of the species.
