 Emeriya, Forel, Ann. Soc. Ent. Beige, xxxiv (1890), C. K. p. ex. 



Type, C. ekgans, Emery, from Italy. 



Mange. Palsearctic, Ethiopian, and Indo-Malayan regions. 



. Head broadly oval ; mandibles rather broad, armed with 

 5 teeth ; clypeus obliquely sloping downwards, slightly convex, 

 anteriorly rounded ; frontal area depressed ; antennae 12-jointed, 

 the club proportionately incrassate and formed of the apical 3 joints; 

 antennal carinse short but prominent ; eyes oval, lateral (in Indian 

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

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

 meso - nietanotal distinctly impressed ; metauotum posteriorly 

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

 species) ; legs elongate, slender ; tibiae without 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 species broadly cordate, usually very much broader than 

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

 basal segment remarkably long. 



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

 indistinct. Thorax elongate, the pronotum distinctly forming 

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

 abdomen as in the : wings wanting." (Emery.) 



c? . " 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 11 of Myrmecocystus bombycinus. Clypeus bicarinate, 

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

 prolonged up the front between the antennal carinae 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. Frontal carinse very short. Antennas 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 anteriorly, 

 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 

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



* Dr. Forel mistook a tf ( ardiocondyla for a $ , which he was unable to 

 identify. For this supposed $ he proposed the genus Emery ia. Subsequently 

 he discovered that this $ WHS really au ergatoid J, and belonged to the genus 

 Cardiocvndyla. It is no wonder therefore that the pedicel should be " as in the 

 genus Cardiocondyla." I have quoted Dr. Forel's description before he found 

 out his mistake.
