channel briglit green (but not quite to apex); joints 1-3 of antennae and 

 legs light flavous, palpi and labrum reddish. Prothorax and elytra shortly 

 pubescent. Head (2'80 mm. wide) convex, strongly punctate, nearly smooth 

 on clypeus and middle of front, traces of striation near eyes, which are fairly 

 prominent; joint 3 of antennae compressed, quite half as long again as 4; 

 labrum strongly emirginate. Prothorax tiansverse (3"o0x4'o0 mm.), mode- 

 rately convex, slightly emarginate at exti'emities, sides evenly rounded, a little 

 more contracted in front than behind, all angles evident but rounded ; median 

 line sharply incised, practically reaching both extremities, basal foveae small 

 but deep, not reaching base, surface coarsely and confluently punctate. Ehjtra 

 ovate, half as long again as wide, base bisinuate, border forming an obtuse 

 angle at shoulder, punctate-striate : intervals slightlj' convex, a rather irregular 

 row of fine punctures along each side of striae, leaving middle of intervals 

 smooth (except for a few stray punctures), 8 and 9 more closely punctate, 

 9 seriate-punctate along inner margins, the punctures much larger towards 

 base and apex. Underside coarsely punctate, ventral surface smooth in middle, 

 some longitudinal striation at sides, prosternal process bordered, metepisterna 

 a little longer than wide. 



A-Uied to C. opacipetuiis Chaud., but more closely to C. coidmrKmensis 

 Andr. Head and prothorax more coarsely, elytra less closely punctate, pro- 

 thorax a little more contracted in front, with green apical margin, elytra 

 bordered with green, underside more coarsely punctate.

Chlaenius yunnanus, n. sp. 



Length 15 mm. Black ; head and prothorax with faint purplish tinge, 

 sides of both and clypeus metallic green; joints 1-3 of antennae, femora, and 

 tibiae (exc. hind pair) testaceous red ; palpi, hind tibiae, and tarsi brown. 

 Elytra and base of prothorax shortly and sparsely pubescent. Head (2"7o mm. 

 wide) moderately convex, hardly shiny, strong!}^ punctate on vertex and at 

 sides, clypeus and middle of front nearly smooth ; joint 3 of antennae slightly 

 compressed, not quite half as long again as 4 ; labrum strongly emarginate. 

 Prothorax transverse (3-25x3'75 mm.), moderately convex, hardly more con- 

 tracted in front than behind, sides gently and evenly rounded, angles obtuse 

 and rounded, especially the hind ones, which are produced a little backwards ; 

 median line distinct, basal foveae linear, short and deep, surface very coarsely 

 but not densely punctate, a few minute punctures among the larger ones. 

 Elytra (575 X 9*50 mm.) ovate, base bisinuate, border obtusely angled at 

 shoulders, rather finely punctate-striate ; intervals a little convex, with a row 

 of very fine, closely-placed punctures on each side of the striae, 8 and 9 hardly 

 more punctate than the others, 9 with a row of large punctures, widely inter- 

 rupted in middle. Underside coarsely, but not closely punctate, ventral surface 

 with a few punctures along sides, prosternal process bordered, metepisterna a 

 little longer than wide. 



The species, although differing in a few minor points, agrees so closely 

 with Fairmaire's description of his C. cofivexus (Ann. Soc. Ent. Fr. 1886, 

 p. 310), also from Yunnan, that I thought they were the same thing. 

 Fairmaire says nothing about the form of the labrum, and I have not seen
