OZOMENA VARIABILIS. 244 



from the others, the pubescent antennae, closed cavities 

 etc. being all characters peculiar to Ozomena. The second 

 joint of the antennae iu the male insect is very short, the 

 following joints however are very slender , elongate and of 

 nearly equal length. In the specimens upon which I look as 

 the females and which differ in no other way except in 

 the shape of the antennae, the latter are much shorter 

 and the joints more flattened , and instead of three flavous 

 apical joints there are only two. The elytra show no traces 

 of the geminate rows of punctures but are irregularly punc- 

 tate. The absence of any longitudinal costae of the elytra 

 will help to distinguish 0. variabilis from its allies. 



I)oridea(?) metallica, n. sp. 



Obscure bluish black below ; head , antennae , thorax and 

 legs fulvous; thorax obsoletely biimpressed; elytra metallic 

 blue , very closely and finely punctured and obsoletely ru- 

 gose. — Length 3 lines. 



Head not longer than broad, impunctate, transversely 

 grooved between the eyes ; antennae about half the length 

 of the body , the second joint very short , the third one three 

 times as long, and as long as the fourth joint; thorax nearly 

 twice as broad as long , the sides very slightly rounded , the 

 surface impunctate , with a shallow transverse depression at 

 each side ; scutellum fulvous ; elytra somewhat flattened , 

 nearly parallel , the shoulders slightly prominent and smooth, 

 the rest of the surface very closely punctured, the inter- 

 spaces finely transversely wrinkled ; tibiae unarmed , the 

 first joint of the posterior tarsi as long as the three fol- 

 lowing joints together; claws appendiculate ; anterior coxal 

 cavities closed ; elytral epipleurae broad at the base , obso- 

 lete below the middle. 



Hah. Sumatra : Rawas and Loeboe gedang (Sumatra Ex- 

 pedition). — Two specimens. 



I am not certain whether I refer rightly the specimens 

 before me to Doridea of which they possess all the cha-
