 Workers and females from Canton (C. W. Howard). 



30. Liometopum sinense, sp. nov. 



Worker. Length, 3.3-4.5 mm. 



Head large and broad, as broad as long, very broad behind, narrowed in 

 front, the anterior corners not swollen and prominent. Mandibles moder- 

 ately convex, with four large apical and five or six smaller basal teeth. Cly- 

 peus rather flat in the middle, ecarinate, with straight, transverse anterior 

 border. Eyes flattened. Frontal area and frontal groove obsolete. Frontal 

 carinae subparaUel, diverging only at their extreme posterior ends. Antennal 

 scapes scarcely reaching beyond the posterior corners of the head; funicular 

 joints 1-6 distinctly longer than broad, joints 7-10 as broad as long, terminal 

 joint as long as the two preceding joints together. Thorax narrower than the 

 head; with distinct promesonotal and mesoepinotal sutures; in profile with 

 the dorsal outline straight, gi-adually sloping backward from the anterior end 

 of the mesonotum to the epinotal declivity, which is a little shorter than the 

 base of the epinotum, feebly convex and more steeply sloping. Petiolar node 

 in profile cuneate, not very thick at the base, inclined forward, narrowed and 

 gradually compressed anteroposteriorly, above with narrowly rounded but 

 rather acute border. Gaster large and somewhat flattened dorsoventrally. 

 Legs moderately long and stout. 



Shining; very finely and densely punctate-shagTeened; mandibles sparsely 

 and evenly punctate. 



Hairs and pubescence pale yellow, the former very delicate and sparse, 

 rather short and of uneven length. Pubescence very short and delicate, 

 closely appressed on the head, thorax, petiole, and appendages, and so dilute 

 as not to conceal the sculpture; on the gaster longer, denser, and coarser, 

 diverging from the middorsal line posteriorly on the first segment and strongly 

 converging towards this line on the second and third segments. 



Reddish brown, gaster dark brown, with the posterior borders of the seg- 

 ments brownish yellow; mandibular teeth black; tarsi yellowish; tips of 

 tarsal claws dark brown; femora, except their bases and tips, darker than the 

 tibiae.
