the petiole is not much more than twice as long as broad. 

 It differs from C. 3-macufatus in the absence of any ferrn- 

 gineous band on the apex of the petiole, and in the less coarse 

 puncturation from C. himalayensis, Cam., which is an alto- 

 gether larger insect, with a long depressed petiole; from 

 C. inter stitialis, Cam., in the absence of any yellow markings ; 

 and from C. etchellsii, Cam., in the absence of a tooth on 

 the apex of the first abdominal segment and in the shape of 

 the petiole.

5 . Black ; a small transverse mark at the base of the 

 clypeus, a spot on each angle of the anterior margin of the 

 pronotum, a minute spot on the tegulse, a band on the apex 

 of the petiole and of the second abdominal segment, the 

 anterior femora beneath, pale yellow. Tegula?, anterior 

 tibiae, ferrngineous. Head and thorax, segments 2-6 of 

 abdomen, more or less covered with a short brown pubes- 

 cence. Wings fusco-hyaline, the costa ferrngineous. Cly-^ 

 peus as broad as long, depressed and broadly rounded at the 

 apex, with two obscure teeth ; vertex with a longitudinal 

 depression ; pronotum broad in front, the anterior angles 

 forming sharp points ; mesonotum flattened posteriorly, a 

 short longitudinal carina running along the surface, median 

 segment convex, with apical angles produced to a point on 

 each side, divided by a longitudinal furrow. Petiole of 

 abdomen as long as thorax, slender, gradually broadening 

 towards the apex, second abdominal segment cup-shaped. 



Punctured ; head and thorax (with exception of median 

 segment) coarsely, median segment and abdomen shining 

 and sparsely punctured. 

 Length 7 mm. 



$ . Differs from female in having the clypeus and scape 

 of antennae on underside yellow.

Nearly allied to Labus (?) macrostylus, Kohl, from Sierra 

 Leone ; both species have petioles of the same form. They 

 may be distinguished by the clypeus, w r hich is convex and 

 slightly emarginate at the apex in L. ? macrostylus, neither 

 of which characters occurs in L. annulatus.

J . Black ; clypeus, the scape in front, a small line behind 

 the eyes, the anterior margin of the pronotum broadening on
