tarsi shorter than the three following joints together ; claws 

 appendiculate ; the anterior coxal cavities closed. 



Amongst the genera with closed coxal cavities and of rounded 

 convex shape Orthaea may be at once known by the deep 

 sulcation above the eyes, the usual frontal tubercles as well 

 as the carina are entirely absent; the short perpendicular grooves 

 at the base of the thorax are another distinguishing character 

 of the genus , which seems best to find its place in Cliapuis' 

 IG.*"* group. 



99. Ox'tliaea A'ii'itlipeiinis, n. sp. 



Below piceous or dark fulvous ; head ^ antenna? thorax and 

 legs fulvous ; thorax extremely finely and closely punctured ; 

 elytra metallic green, strongly and closely punctate-striate, the 

 interstices minutely punctured. 



Length 2 lines. 



Head convex with a few very fine punctures , the lateral 

 broad sulcation bounded by an acute ridge ; clypeus broad , 

 divided from the face by a transverse groove, its surface smootli ; 

 antennjje extending a little below the base of the elytra, entirely 

 fulvous, the first joint slender, curved and thickened towards its 

 apex , the second joint sliglitly shorter than the third, the fol- 

 lowing subequal, of somewhat triangular shape, equal in length; 

 thorax twice as broad as long , rather strongly narrowed in 

 front , the sides rounded , the anterior angles prominent , the 

 posterior margin sinuate at the sides with a very short longi- 

 tudinal groove at eacli side , the surface extremely minutely 

 and closely punctured; scutellum fulvous; elytra i-atlier strongly 

 punctate-striate the punctures near the suture much finer than 

 the others and irregularly placed , the lateral margin smootii ,
