314 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I4I 



Crematogaster limata parabiotica Forel 



Commensal. — Phorticolea holiviae, Bolivia, Cachuela Esperanza 

 (Caudell, 1923) : Collected in joint nests of C. limata and Compo- 

 notus femoratiis. 



Solenopsis geminata (Fabricius) 



Commensal. — Myrmecohlatta wheeleri, Guatemala (Hebard, 

 1917a) : Collected from a colony of this ant under a stone on the 

 shores of Lake Atitlan, altitude 11,719 feet. 



Unknown host 



Cockroach. — Attaphila flava, British Honduras (Gurney, 1937) : 

 Because the known hosts of the other five species of Attaphila are 

 ants, we presume that this species also lives in the nest of some myr- 

 mecine ant. 



Subfamily PONERINAE 



Odontomachus affinis (Gueiin) 



Commensal. — Myrmehlattina longipes, Brazil, Rio de Janeiro 

 (Chopard, 1924, 1924a; Hancock, 1926): Originally described as 

 Phileciton longipes by Chopard (1924) from the nest of an ant mis- 

 takenly identified as Eciton sp. 



Family VESPIDAE 



Polybia pygmaea Fabricius 



Commensal. — Sphccophila polyhiarum, French Guiana (Shelford, 

 1906a) : Shelford stated that it was probable that the cockroaches 

 living on the floor of the paper nest fed on small fragments of insects 

 and spiders that were dropped by the wasp larvae feeding in the cells 

 above. 



Family MEGACHILIDAE 



Melipona nigra Lepeletier 



Commensal. — Oulopteryx m,eliponarum, Brazil (Hebard, 1921) : 

 According to Hebard, this cockroach is the first one to be known to 

 inhabit the nests of bees. Nothing is known of the relationship be- 

 tween the cockroach and the bees. [See comment by Sonan (1924) on 

 page 318.]
