Michigan. It probably is local and becomes adult early in 
the season. The two large hooks on the dorsal side of the 
tibia of the palpus are very characteristic.

This brilliant spider was wrongly synonomized in the 
New England List of Spiders in 1908 and unfortunately 
later workers have continued the error. The original de- 
scription of Herpyllus auratus Hentz is rather vague, but 
the brilliant color and the two pairs of lateral bars on the an- 
terior half of the abdomen is emphasized. In the south, there 
is found a Castianeira with similar markings which probably 
is the spider that Hentz had, as the figure shows the head 
only slightly narrowed, a character found in Castianeira, 
rather than Micaria and no indication of an abdominal con- 
striction that is usually found in Micaria. 
Mr. Banks in his Catalogue, 1910, places Herpyllus 
auratus Hentz as a Castianeira and in 1913, Mr. Emerton 
wrote a brief description and figured the female and the 
male palpus, the female was from Staten Island, N. Y. and 
the male from Falls Church, Virginia. This he calls Casti- 
aniera aurata Banks, not Hentz. (Bull. Amer. Mus. Nat. 
Hist., 22 : 258). 
Micaria aurata is a misidentification and therefore a 
new name is necessary. I propose for it delicatula. Accord- 
ing to Kaston, it is found in Connecticut. The only adult 
male in the collection at the Museum of Comparative Zoology 
is from the Sand Spit, Cold Spring Harbor, Long Island, 
N. Y. It differs from Micaria longipes Emerton with which 
has been synonomized, by the longer and more slender tibia 
of the palpus and the brilliant coloring.
