240 ANTIPIIA APICIPENNIS. 



obsolete below the middle. Legs black , the femora some- 

 times fulvous; tibiae unarmed ; anterior coxal cavities closed. 

 Hah. Sumatra or.: Tandjong Morawa, Serdang (Dr. 

 Hagen) , Deli (Schagen van Leeuwen). — Three specimens. 



Ozomena (Theopea) variabilis , n. sp. 



Violaceous blue ; antennae (the two apical joints excepted) 

 black ; thorax transverse , deeply impressed , impunctate ; 

 elytra closely and distinctly punctured , the interstices 

 obsoletely rugose. — Length 2^/3 — 3 lines. 



cf . Antennae filiform, long and slender, strongly pubescent. 



9. Antennae with shorter and broader joints. 



var. Elytra cupreous. 



Head impunctate , deeply grooved between the eyes ; the 

 frontal tubercles in shape of a narrow transverse ridge ; 

 eyes large; labrum and jaws black; antennae as long as 

 the body , black , the apex of the 9^^ joint , and the two 

 apical ones , flavous , extreme apex of the terminal joint 

 black. Thorax about one half broader than long , the sides 

 nearly straight and slightly narrowed in front , the disc 

 with a deep sinuate transverse groove , not extending to 

 the sides, impunctate, metallic violaceous blue. Scutellum 

 black. Elytra closely punctured, the punctures for the most 

 part arranged in irregular double rows near the suture, 

 but irregularly at the sides , where the interstices are trans- 

 versely rugose. Anterior coxal cavities closed. Tibiae un- 

 armed. Claws appendiculate. 



Hab. Sumatra or.: Tandjong Morawa, Serdang (Dr. Hagen). 

 — Five specimens. 



There is a considerable difference in the shape and struc- 

 ture of the thorax between this species and several of its 

 congeners , notably 0. impressa Fabr. In the latter the 

 thorax is square-shaped with two deep foveae , in 0. varia- 

 bilis the thorax is transverse and the two impressions are 

 replaced by a sinuate groove. Nevertheless I cannot find 

 sufficient other marks of distinction to separate this species
