Fig.l DoUchoderus (Hypoclin a) sinensis, sp. nov., worker. 



Worker. Length 3.4 mm. 



Closely related to the Palearctic D. quadripunctatus L. but dif- 

 fering in the following partickilars : Joints 3-7 of funiculi shorter, 

 not longer than broad; mesonotum slightly longer, more nearly 

 parallel-sided; base of epinotum much more elevated and convex 

 and broader in proportion to its length; its posterior corners de- 

 pressed and developed as small, rather acute teeth, not as tubercles. 

 Petiolar node distinctly lower and more evenly rounded above in 

 profile, the cylindrical portion behind the node longer. 



Surface of head, thorax and petiole much more opaque; the 

 foveolae on the head and thorax more regular and more distinct. 

 Mandibles, clypeus and pleurae slightly shining, or lustrous, finely 

 shagreened. Gaster very smooth and shining. 



Pilosity and pubescence quite as feebly developed as in quadri- 

 punctatus. 



Head, thorax, petiole and legs deep red, the tibiae slightly darker ; 

 tarsi, mandibles and antennae slightly paler, the tips of the scapes 

 and funiculi infuscated. Gaster black; first and second segments 

 as in quadripunctatus, each anteriorly with a pair of ivory yellow 

 but somewhat larger spots. 



Described from a single specimen from Canton.
