Remarks on synonymy: It is unfortunate that most workers since 
about 1930 have accepted without question Simon’s (1901: 624) 
synonymy of Attus militaris Hentz 1845 with Attus marginatus 
Walckenaer 1837, for the synonymy is incorrect: Walckenaer’s orig- 
inal description (p. 466) and Abbot’s figure (number 444) clearly 
refer to Hentzia palmarum (Hentz). Walckenaer refers to an elon- 
gate abdomen, a fawn-brown first pair of legs, yellow posterior legs, 
and chelicerae elongate and held in front, whereas Eris militaris has 
an abdomen of typical width, posterior legs strongly marked with 
dark brown, and chelicerae robust and divergent. Abbot’s drawing 
(see Figure 1), on which Walckenaer based his description of A. 
marginatus, unambiguously portrays a male Hentzia palmarum, 
given that his specimen was from Georgia. Because the name margi- 
natus is inappropriate for the transamerican Eris species, another 
name must be used. The type material for the next oldest name, 
Attus militaris, is apparently lost or destroyed. Burgess (1875, vii) 
said that only 60 specimens glued on cards remained of Hentz’s 
collections, the remainder having been destroyed. The surviving 
specimens were in the collection of the Boston Society of Natural 
History, which has subsequently become the Boston Museum of 
Science. The Museum of Science no longer has these specimens nor 
any record of them (D. Salvatore, pers. comm.), nor does the MCZ, 
which received many of the Society’s collections. I presume Hentz’s 
types to have been lost or destroyed. Without the type material the 
interpretation of Attus militaris is not entirely clear, for Hentz’s
