1919] Wheeler: The Genus Metapone 181 



Male (mature pupa). Length 7 mm. 



Mandibles small, tridentate. Clypeus very large, convex in front, 

 flattened behind. Head slightly longer than broad; eyes occupying 

 more than half its sides. Frontal carinse parallel, as far apart as 

 they are from the lateral borders of the head. Front truncated anteriorly 

 and separated from the preocellar space by a transverse carina con- 

 necting the frontal carinas. Antennal scrobes small, marginate behind 

 and laterally. Antennal scape very short, scarcely longer than broad; 

 first funicular joint very small, globular, broader than long, the remain- 

 ing joints cylindrical, the more basal a little broader than long, but 

 increasing gradually in length, the last twice as long as broad. Thorax 

 as broad as the head, rather flat. Mesonotum with Mayrian furrows; 

 scutellum behind with two short, flat, horizontal teeth. Epinotum 

 subcuboidal, its base longer than its declivity. Petiole and post- 

 petiole as in the worker, but the former much broader than long, more 

 rounded and not emarginate behind, with a small anteroventral tooth, 

 the postpetiole unanned below. Gaster elongate. Legs of the ordinary 

 form, not dilated. 



Head and thorax opaque or subopaque; longitudinally rugose, with 

 reticulate interrugal spaces; sides of thorax striated. Clypeus coarsely 

 and transversely rugose. Pedicel and anterior half of gaster densely 

 reticulate-punctate and opaque or subopaque; posterior half of gaster 

 becoming more shining. Postpetiole longitudinally rugose above and 

 coarsely rugose on the sides like the posterior portion of the epinotmn. 



Erect hairs very oblique on the appendages, nearly appressed, almost 

 absent and very short on the scapes. Pubescence somewhat more 

 abundant than in the worker. 



Black; margins of gastric segments, genital valves, tarsi, tibiae and 

 scapes sordid yellow or reddish; funiculi brown. 



Type-locality: Peradenyia, Ceylon (E. E. Green).

Worker. Length 7.6 mm. 



Somewhat smaller than greeni. Mandibles 5-toothed, their outer 

 margin feebly convex and their basal lobe smaller. Anterior lobe of 

 clypeus much shorter than in greeni and sauteri, but also rather 

 rectangular. Head rectangular, about one-third longer than broad, 

 not broader behind than at the base of the frontal carinae, only anteriorly 

 somewhat narrower, with nearly straight sides and feebly concave 

 posterior border (in greeni broader behind and more convex laterally, 

 longer in sauteri). Scape and funiculus more slender than in greeni, 

 about as in sauteri. The very small, perfectly flat eyes have only a few 

 indistinct ommatidia and lie as in greeni below the hind end of the 

 scrobes, but are much smaller. Whole head in profile appearing as 

 if very obliquely truncated anteriorly, i. e., with the anterior half of the 

 clypeus much more abruptly declivous than in greeni and sauteri so
