ygaeus javanicus, n. sp. 



Niger ^ nitidus, convexus, anfennarum apice ferrugineo, tar- 

 sis rujis ; prothorace inaequali, dense fortiterque puncfato; 

 elytris profunde sulcatis, interstitiis convexis , partim latis. 

 — Long. 6 millim. 



Head with the upper surface somewhat uneven, rather 

 closely and 'finely, but irregularly, punctate, scarcely shi- 

 ning. Antennae reaching backwards slightly beyond the 

 base of the thorax; piceous-black , at the base with five 

 joints free from sensitive pubescence and therefore some- 

 what shining; the joints from this to the extremity are 

 somewhat broader, the penultimate joint being scarcely so 

 long as broad, they are densely pubescent, and the ter- 

 minal joint — as also the apex of that preceding it — 

 is ferruginous. The thorax is strongly transverse , and 

 very convex in the transverse direction ; it is strongly 

 narrowed in front, the sides are somewhat irregular in 

 outline, and are a little rounded and very slightly con- 

 tracted behind near the hind angles ; the base is deeply 

 sinuate on each side of the middle, and also less deeply 

 emarginate in the middle in front of the scutellum ; the 

 surface is uneven , bearing several rather indefiuite impres- 

 sions, it is glabrous, and is rendered rough by a deep, 

 coarse punctuation which is somewhat irregularly distribu- 

 ted, the punctures being iu some places nearly confluent:
