of the information which a study of the type of -figulum would give, 

 the present disposition of the respective names seems the best pos- 

 sible, and is the same as used by Kohl in his revision. 



The descriptions of himaculatus and vlndex by Lepeletier are iden- 

 tical in almost every respect, and there is little doubt that these 

 names are synonyms of jigulum. As described by Spinoia, chilenfiis 

 differs from fgulum only in having the propodeum entirely black 

 instead of with three spots of yellow. In two specimens from Chile 

 which the writer has studied, both male and female had a very small 

 amount of yellow on the propodeum, represented by several faint 

 spots at the posterior end, and none at the sides. A series would 

 probably show a variation similar to that occurring with 

 caementaHum. 



The differences between figuluni and caementaHum have already 

 been noted. Superficially, fgulu7n has also some resemblance to 

 iistulare, but with the latter, the propodeum is marked oft' below by a 

 deep, definite groove, and has six spots of yellow, neither of which 

 features occur with fgulum.
