LOntOMYEMEX. MYRMECINA. 197 



situated about the middle of the sides of the head. Thorax of the 

 shape characteristic of the genus, but the pronotum unarmed and 

 the metanotal spines more erect than in the other two species and 

 very long, slender and acute. Pedicel : the 1st node rather thick, 

 as broad as long, with a long and rather slender petiole in front ; 

 2nd node rounded above, broader than the 1st node ; abdomen 

 oval, slightly truncate anteriorly. 



Length, ^ 2-2-5 mm.

 Maymyo, 3000 feet (Bingham). 



Genus MYRMECINA. 

 Myrmecina, Curtis, Brit. Ent. iv (1829), p. 226, S ■ 



Type, M. latreilli, Curtis, from South of England. 



Range. Palsearctic and Indo-Malayan regions. 



^ . Head somewhat square, widely emarginate posteriorly, 

 the lateral angles not prominent ; mandibles flat, triangular, 

 indistinctly dentate, maxillary palpi 4-, labial palpi 3-jointed ; 

 clypeus bicarinate and bidentate (only bicarinate not bidentate in 

 the Indian species) ; antennje 1 1-jointed, the club of the flagellum 

 consisting of the apical three joints. Thorax short, broad 

 anteriorly, narrowed posteriorly, sutures obsolete ; metanotum 

 with the lateral angles of the very short basal portion furnished 

 with a strong spine pointing backwards ; legs short and stout. 

 Pedicel short : the 1st node quadrate without petiole in front; 2nd 

 node a little longer than broad, closely attached to the 1st node in 

 front and to the abdomen posteriorly ; abdomen oval, rather 

 acuroinate posteriorly. 



2 . Closely resembles the ^ ; head broader than long, mandibles 

 proportionately larger ; thorax and abdomen more massive, meta- 

 notal spines thicker, more robust. 



(5 . Head proportionately much smaller than in the ^ or 5 , 

 globose ; eyes very large ; mandibles rather small, triangular when 

 closed, covered somewhat by the large labrum ; antennae 1 3-jointed, 

 the scape very short, a little longer than the 2nd joint of the 

 tiagellum, the 1st joint of the latter about half the length of the 2n(l. 

 apical joint the longest ; mesonotum divided into three subequal 

 portions by a deep 'TP-shaped sulcus; metanotum with the basal 

 portion obliquely sloping, bidentate at the posterior lateral angles, 

 the apical portion vertical. Wings : the fore wing with a large 

 subopaque stigma, one radial and one cubital cell. Pedicel and 

 abdomen much as in the ^ . 



Only one species has so far been recorded from within our limits. 

 1 have carefully examined the type, a d' , of Mgrmeciua /nlicornia, 

 Smith (Cat. vi (1858) p. 133), and I am convinced it does not 

 belong to this genus ; it is possibly a l^etrarnoriurii, and has the Ist 

 node of the pedicel distinctly petiolate.
