C’ATOCALA PERPLEXA.

Secondaries red, of a somewhat deeper shade than Parta ; median band extends almost to 
the abdominal margin ; fringes white. 
Under surface resembles that of Parta in a great measure, the principal difference being 
that the mesial band extends almost to the interior margin, in which respect it is nearer to 
some examples of Unijuga. 
Two examples from which the above description was taken were captured in the vicinity 
of Brooklyn, X. Y., by Mr. Julian Hooper of that city, one of which, the original of the 
figure on plate V, he generously added to my cabinet. 
I am not partial or addicted to the divertisement of hunting Lepidopterological mare’s 
nests, but I must confess that this insect has perplexed me considerably; I showed it in company 
with Parta to a valued entomological friend, asking him if he thought it might be the latter, 
“ I would not like to figure it as the typical form ” was the answer, so, without arriving at 
any definite conclusion, I have offered the figure for the inspection of lepidopterists, and with 
much doubt provisionally cite it as a variety of Parta ; the first and principal differences are 
the dark blueish color, and two conspicuous white bars of primaries, neither is there that soft 
smooth appearance so noticeable in Parta, there being more of a tendency to squamoseness as 
in Unijuga; then again the sub-reniform is connected with the transverse posterior line whilst 
in Parta it is entirely isolated, there are besides many minor points of difference and altogether, 
after frequent examinations, I am completely at a loss what to think about it, especially as both 
Parta and Unijuga, the two species to which it is the nearest, ( if it be not identical with one 
or the other, ) have less tendency to variation than any others I wot of, and it would be perhaps 
venturing too far to hazard the conjecture that it be the result of a love affair between those 
two.
