 Dedicated to my former instructor, Dr. Alexander Petrunkevitch, in 

 appreciation of his contributions to the science of arachnology. 



Simonella myrmeciaeformis (Tacz.). 



Janus myrmeciaeformis Taczanowski, Horae Soc. Ent. Rossicae, Vol. 8, 

 p. 125, pi. 4, fig. 9 (1871). 



Simonella myrmeciaeformis Peckham, Occas. Papers Nat. Hist. Soc. Wis- 

 consin, Vol. 2, no. 1, p. 81, pi. 7, fig. 4 (1892). 



It seems evident that the above cited descriptions do not refer to the 

 same species. Taczanowski's material came from French Guiana and was 

 described as being ochre-yellow with four black spots on the head and with 

 two pale annulations on the abdomen. Peckham in his 1892 paper, redes- 

 cribed the species as with a black head, a white band around the constric- 

 tion, and with the posterior segment of the abdomen dark brown. The 

 original locality (French Guiana) is cited and an additional locality, 

 Chapoda (Chapada), Brazil (Collection (H. H.) Smith). It is probable 

 that the Brazilian specimen or specimens represent the species described by 

 Peckham and that it is an unnamed species. For numerous reasons I do 

 not care to attach a name to the description.
