CERAMBYCIDAE. 325 



pubescence. They arc related to Acaiitliodei'ini, having, like 

 tiieiii, the claws divaricate, the body generally rather stout, and 

 the scape of the anteninie without cicatrix; the front quadrate, 

 tvith coriaceous support to the labrum. They differ in liaving the 

 scape of the antennae rather shorter and stouter than in the group 

 Liopi, to which they bear the strongest resemblance; the autcuuuj 

 are only a little longer or shorter than the body, the outer joints 

 gradually shorter ; the eyes are moderately or very coarsely 

 granulated (Eupogonius); the front coxal cavities are angulated 

 externally, completely closed behind; the middle ones are angu- 

 lated, but not open externally ; the legs are short, thighs strongly 

 clavate in some genera, but not so in Eupogonius and Lypsimena; 

 the middle tibiae have an external sinus in some genera, and are 

 quite simple in others; the 1st joint of hind tarsi short or only 

 slightly elongated. 



The genera of this tribe are dispersed by Lacordaire among his 

 groups, Estolides, Apodasyides, and Pogonocherides ; with the 

 exception of Hoplosia, wliich resembles a Graphisurus, but with 

 the antenniB of Acantlioderes, the genera have a characteristic 

 habitus. 



Five groups are indicated: — 



Middle tibiae with external sinus; thighs clavate; vertex concave; an- 

 tennal tubercles prominent. 2. 



Middle tibiae without external sinus ; thighs not clavate ; vertex fiat or 

 convex ; antennal tubercles not prominent. 5. 



Middle tibiai with external sinus ; thighs stout, not clavate ; eyes coarsely 

 granulate, vertex convex. Zaploi. 



2. Eyes moderately granulated ; scapeof antennae uniformly punctured. 3. 

 Eyes very coarsely granulated ; scape with large punctures inter- 

 mixed. 4. 



3. Lower lobe of eyes elongate. HoPLOsiiE. 

 Lower lobe of eyes as wide as long. Pogonochebi. 



4. Lower lobe of eyes broader than 1 mg, Estol^. 



5. Eyes coarsely granulated, lower lobe as wide as long ; scape of antennae 

 uniformly punctured. Eupogojjii. 



Group 1. — Estolae. 

 The only representative of this group in our fauna is Ei^fola 

 sordida from Lower California. The generic determination was 

 made by Mr. 11. W. Bates, who possesses a familiar knowledge 

 of tropical American Cerambycidse, unrivalled by any other 

 student.
