Cotyves.—Q^^i. No. 24449, U.S.N.M. 



Described from one female and many workers taken from a num- 

 ber of colonies found in rotten wood, where it resembled in nesting 

 habits and habitus Megaloinyrmex silvestrii Wheeler. 



A. honduriana is much smaller than the other Central American 

 Aphaenogastei's and is characterized by the short neck, the elongate 

 antennae with four- jointed club, by the sculpture and color. 



There is, in the series before me, some variation in sculpture and 

 in the degree of the angle between the base and declivity of the 

 epinotum, which in some workers is very finely dentate at the sides 

 and in the others roundly angulate. 



APHAENOGASTER (DEROMYRMA) PHALANGIUM Emery. 



Honduras : San Pedro Sula. 



Several colonies found in canons near the city Avere beneath stones 

 near streams. This species is "mimicked" by a spider and an 

 Alydid bug. both of which T fomid only in the same locality as the 

 ants.
