ANTHRIBIDAE. 525 



margin of the elytra is not acutely elevated, though quite distinct 

 in H. granulatuii and pinij'ea;. 



Three genera, which extend across the northern part of the 

 continent, are indicated by our species : — 



Front coxae contiguous or nearly so. 2. 



Front coxae widely separated. Scierus. 



Third joint of tarsi emarginate. Hylastes. 



Third joint of tarsi bilobed. • Hylurgops. 



Fam. LXXXIIL— ANTHRIBIDAE. 



Mentum large, deeply emarginate in front, closely connate 

 (except in the group Ilorrnisci) with the gular peduncle, 

 which is broad and short; buccal fissures consequently nar- 

 row, only partially exposing the base of the maxillas; ligula 

 large, corneous, narrowly emarginate at tip; palpi 3-jointed, 

 inserted at the sides of the lower face of the ligula, distant, 

 slender, cylindrical, longer than in othe* Ehynchophora and 

 flexible, as in normal Coleoptera and in Bliinomaceridge; 

 last joint elongated, narrower at the tip. 



Maxilla^, visible in the narrow buccal fissures, with two 

 narrow lobes, usually rounded and ciliate at tip; palpi slen- 

 der, 4-jointed, with the last joint longer and narrower ax 

 the tip. 



Mandibles flattened on tlie upper surface, curved, pointed, 

 or emarginate at tip. 



Antennre inserted usually under the sides of the front, 

 rarely upon the front. They are 11-jointed, slender, and 

 not geniculate; the first joint is stouter, but scarcely longer 

 than the second ; joints 3-8 slender, pubescent; 9-11 broader, 

 more or less com])ressed, finely pubescent and sensitive. 

 The antennte of the '5 are sometimes much longer than the 

 body. The outer joints form a compact oval club in Hor- 

 miscus. 



Head prominent, not deflexed ; beak broad, flat, sometimes 

 so short as to be indistinct; never cylindrical or slender, and 

 never separated from the front by a transverse impression. 

 Eyes moderate in size, not very finely granulated, rounded, 

 sometimes slightly emarginate in front. Labrum distinct, 

 quadrate, fringed with hairs. Gular suture completely 

 obliterated. 



Prothorax of varied form, usually trapezoidal and truncate 

 in front; rarely somewhat rounded over the head(Choragus);
