liaii(/e. Palirarctic, Ethiopian, and Intlo-Malayan regions. 



^. Head broadly oval; mandibles rather broad, armed with 

 5 teeth ; clypeus obliquely sloping downwards, slightly convex, 

 anteriorly rounded ; frontal area depressed ; antenna) 12-jointed, 

 the club proportionately incrassate and formed of the apical ^J joints; 

 antennal carintc sliort but prominent ; eyes oval, lateral (in Indian 

 species below the middle line of the head) ; no ocelli. Thorax 

 short and stout, the pro-mesonotal suture obsolete above, the 

 meso - uietanotal distinctly impressed; metanotum ))osterior]y 

 armed with two stout spines (very short and thick in Indian 

 species) ; legs elongate, slender ; tibife withont calcaria. Pedicel 

 very long ; the 1st node with cylindrical petiole, long in front, 

 short posteriorly, node itself from above oval ; 2nd node in the 

 Indian S])ecies broadl}' cordate, usually very much broader than 

 long ; abdomen oval, lightly truncate or emargiuate in front, the 

 basal segment remarkably long. 



" $. Head as in ^ but shorter; ocelli three on tlie vertex, 

 indistinct. Thorax elongate, the pronotum distinctly forming 

 part of the dorsum ; the two metanotal spines thick. Pedicel and 

 abdomen as in the ^ : wings wanting." {Emery.) 



S . "' Mandibles very long, very narrow, without a terminal 

 margin, nearly straight along the basal half, curved along the 

 apical half, terminating in a long acute point, a little enlarged and 

 depressed towards their middle, constricted near their base, without 

 trace of teeth. Between the mandibles is a wide space similar to 

 that in the 1/ of Myrmecocystus homhycinus. Clypeus bicarinate, 

 emarginate, and with a deep groove between the carinae, the groove 

 prolonged up the front between the antennal carinas up to the 

 middle of the vertex. No ocelli. Head widened and somewhat 

 rounded posteriorly, constricted in front ; it has, however, a 

 posterior margin. Eyes rather small, situated in the anterior 

 third of the head. Prontal carina) very short. Antennie with 

 11 joints; the last very broad and thick, forming the club of the 

 flagellum. The scape does not nearly reach the posterior margin 

 of the head. The pronotum has distinct shoulders and anterioi-ly, 

 tow ards its articulation with the head, is formed into a ladder-like 

 slope. The mesonotum is short and very broad, laterally the 

 margins project triangularly in form of a thick festoon. Meta- 

 notum armed with two short spines. Pedicel as in the genus 

 Curdiocondyla *. The 1st joint is petiolate in front and has a 



* Dr. Forel mistook a (^ ( ardiocovdijUi for a ^, which lie was unable to 

 identify. For this supposed ^ lie proposed the genus A'/z/c/v/m. Subsequently 

 he discovered that this ^ w;is really an crgatoid c?, and belonged to the genus 

 Cardiocondi/lu. It is no wonder tlierefore that tlie pedicel sliould be " as in the 

 genus Cardioeondyla." 1 have quoted Dr. Forel's description before he found 

 out his mistake.
