ANTHRIBIDAE 49 



a narrow suturai stripe; between bands 2 and 3 a small limbal 

 spot ; on the apical area fine spots : three in a triangle and two 

 at the apex. These markings may be assumed to be variable. 

 Fore tibia and all the tarsi sparsely pubescent grey, mid and 

 hind tibiae appearing black with a whitish basal ring. 



Rostrum as long às apically broad; a median depression broad 

 apically, narrowing basally and continued on to the frons, bearing 

 at the base, an indication of a thin median carina; this groove 

 is flanked on the frons by a carina which becomes more definite 

 at the base of the rostrum where it curves laterally and then 

 distally, extending to the apex of the rostrum and running nearly 

 parallel with the lateral' margin of the latter; this carina forms 

 the outer edge of a raised dorsal area which extends from the 

 base to beyond middle ; the cariniform edge of the antennal groove 

 is continued as a carina to the apex of the rostrum , and from it 

 another carina runs backwards, but is broken up by puncturation 

 before reaching the eye.. Groove below the eye deep. The frons 

 is a little wider than the second antennal segment is long. Club 

 of antenna slender, the relative lengths of segments VIII to XI 

 being 16, 18, 15, 19. 



Prothorax half as broad again as long (17: 11). Carina dor- 

 sally almost straight, very slightly convex, with a very faint 

 indication of a median angle, laterally gently flexed backwards 

 and * forming an even arc with the lateral carina , the latter 

 straight, oblique, with its centre very faintly curved upwards. 



Elytra evenly punctate-striate ; subbasal hump not prominent. 

 Pygidium as long as broad. 



Intercoxal process of mesosternum narrower than in A. oli- 

 vaceus. Abdomen medianly flattened, anal segment about as long 

 as II, III and IV together, apically sinuate. First hind tarsal 

 segment a little over half as long again as segments II to 

 IV together.
