CRYPTOPONE. 105 



lightly punctured ; head opaque, thickly punctured, thorax near 

 the mesonotum narrowly raised, metanotum scarcely depressed but 

 moderately compressed, posteriorly obliquely truncate, the declivous 

 face shining, pedicel rouuded above, below furnished witli a lamina, 

 the posterior portiou of the abdomen shining.'" (Emery.) 



" 5 . Elongate, opaque, testaceous ; eyes large, black, slightly 

 prominent ; head subquadrate, posteriorly bilobed, with three 

 distinct ocelli; front raised between the base of the antennae, 

 carinate ou each side, the cariiise posteriorly close together, 

 parallel ; clypeus truncate ; mandibles porrect, with 5 acute teeth ; 

 antennae clavate, about half the length of the body, 12-jointed; 

 thorax narrower, the head elongate ; node thick, subquadrate, 

 with the angles rounded ; abdomen about as broad as the 

 thorax, elongate, the first two segments arched, the three follow- 

 ing segments shorter, attenuate towards the apex ; wings whitish 

 hyaline, nervures testaceous.'" (MotscJi.)

Hab. Eecorded so far only from Ceylon. 



Subfamily MYRMECIN.E. 



Sufficiently distinguished from the other subfamilies of the 

 Formiciche by the pedicel being distinctly 2-jointed in all the sexes. 

 The neuters of the genus yEnidus also have the pedicel 2-jointed 

 ( (S one-jointed, $ unknown), but they are absolutely without 

 eyes or ocelli, and could only be mistaken for the neuters of 

 Liomyrmex. Trom the latter, however, they can be distinguished 

 at a glance by the long, thick, and massive antenna? ])lanted 

 extremely close to the anterior margin of the head with their bases 

 very close together. In Liomynnex, on the contrary, the antennae 

 are short and slight, planted proportionately at a distance from 

 the anterior margin of the head and with their bases wide apart. 

 The sting in the j\Jyrmecin(v is present but not often exserted, and 

 the pupae are not enclosed in cocoons.
