wheeler: CHINESE ANTS. 537 



apical borders bearing two larger terminal and three or four minute basal teeth. 

 Clj'peus with entire, broadly rounded anterior border. Scapes of antennae 

 verj' short, not longer than the first two funicular joints together, broader at 

 the base than at the tip; funicular joints all longer than broad. Thorax 

 resembling that of the European ^. gibbosa Latr., but more extreme, the poste- 

 rior extension of the epinotum being nearly as long as the more anterior portion 

 of the thorax and the constriction separating the two being more pronounced. 

 The epinotal spines are reduced to a pair of minute teeth. Mesonotmn 

 extremely convex, in profile with a vertical, rounded, anterior and horizontal, 

 rounded posterior surface. Nodes of the petiole and postpetiole very low, 

 the peduncle of the former cylindrical, constricted anteriorly, the post- 

 petiole campanulate. Gaster subtriangular. Legs, including the coxae, 

 very slender, the middle and hind femora sinuately bent. 



Smooth and shining; head opaque, finelj^ and densely punctate, slightly 

 shining about the ocelli. Pronotum very sparsely and rather coarsely punc- 

 tate. 



Hairs longer arid much sparser than in the worker. 



Black; legs piceous; mandibles, antennae, and tarsi dull yellowish. Wings 

 colored as in the female, but the pterostigma is paler. 



Described from eighteen workers, nine females and ten males taken 

 from a single colony at Soochow by Prof. X. Gist Gee, to whom the 

 species is dedicated. Also workers from Foochow. It is related 

 to the Japanese A. famclica F. Smith, of which only the worker is 

 known. This form is more brownish and less reddish, smaller and 

 more slender, with longer head and antennae, and the scapes have no 

 lobe at the base; the sculpture is feebler, the head behind and the 

 pronotum, petiole, and postpetiole are smoother and shining, the 

 t^ans^•e^se rugae on the base of the epinotum are more pronounced 

 and the epinotal spines are smaller and more erect. The pro- and 

 mesonotum above are not so high and rounded as in geei. The work- 

 ers of the latter were compared with three workers of famelica from 

 Saitama, Japan, in my collection. 



22. Aph.\enogaster exasperata, sp. nov. 



Worker. Length, 5.5-6 mm. 



Head oval, without posterior corners, less than 1^ times as long as broad, 

 with marginate occipital border. Eyes convex, at the middle of the sides. 

 Mandibles with slightly concave external borders, with three large apical and 

 several smaller basal teeth. Clypeus rather flat in the middle, its anterior 

 border indistinctly notched. Frontal carinae erect, lobular, prominent. 

 Frontal area large, triangular, impressed. Antennal foveae large. Antennae
