CERAMBTCIDAE. 345 



Tribe XIII.— IIIPPOPSIM. 



The body is extremely slender, the antennae very long in the 

 first group, short in the others ; the front is very long and 

 inflexed, so that the mouth is near to the presternum ; it is small, 

 and the mandibles are nearly perpendicular to the inflexed front ; 

 the support of the labrum coriaceous, the palpi not slender 

 and the last joint almost conical and pointed. The eyes are 

 coarsely granulated, emarginate or divided, in the latter case, the 

 upper lobe is sometimes (Spalacopsis) wanting. Prothorax long, 

 cylindrical ; elytra elongate. Front coxa3 angulated in Hippopsis, 

 rounded in the others, closed behind, middle ones open externally, 

 mesosternum truncate between the coxa?. Ventral segments 

 nearly equal, the 1st sometimes longer, 5th broadly truncate. 

 Legs rather short, equal, middle tibiae with an external tubercle, 

 tarsi as long as the tibiae, 1st joint of hind pair short, or slightly 

 elongated (Hippopsis), last joint rather long, claws divergent. 



Our three genera indicate different groups. 



Front coxae angulated ; 



Antennae very long. Hippopsis. 



Front coxae rounded ; antennre short ; 



Antennae very pilose, scape not longer than 3d joint ; head not elongated, 



eyes emarginate, upper lobe narrow. Dokcasta. 



Antennae sparsely pilose, scape very long ; head as long as prothorax, 



eyes divided, upper lobe wanting. Spalacopsis. 



Dorcasta Pascoe is equivalent to iEgilopsis Horn, and one 

 species, D. cinerea Horn, occurs in Texas. 



Spalacopsis occurs in Florida and Texas; Eutheia || Guer., 

 Eulhuorus Duval, was established upon a Cuban species, differ- 

 ing from ours by the antennae much more hairy, and the scape 

 somewhat longer. These differences do not seem to be generic. 



Tribe XIV.— S A l>l It l>l M. 



. Insects of cylindrical form, of large or medium size, with large, 

 flat, quadrate, vertical front, coriaceous labral support, and 

 finely granulated, deeply einarginate eyes. The palpi are less 

 slender than in the Acanthoderoid series, the last joint more or 

 less oval, truncate at tip. The antennas are as long as the bodv, 

 or a little shorter; the scape is marly cylindrical, a little shorter 

 than the 3d joint, without apical cicatrix; the outer joints
