DESCRIPTIONS OP NEW SPECIES. 175 



minent; mesosternum rather wide, truncate behind, middle coxal 

 cavities open externally. Legs moderate, thighs not clavate, 

 tibial spurs very small, hind tarsi with the 1st joint equal to the 

 others united. 



490. Eu. villicornis. Saturate testaceus, thorace (%) opaco, 

 subtilissime alutaceo et subsericeo, latitudine breviore, lateribus valde 

 rotundatis, linea dorsali \sev'\, cicatrice vix elevata, sublunata ntrinque 

 notato ; elytris vage punctatis, pilis erectis baud dense pubesceutibus, 

 spina parva subsuturali armatis, dorso utrinque lineis duabus obsoletis. 

 Long. 18 — 24 mm. 



One male, Arizona. Resembles in appearance Oeme, but is 

 less slender ; the sculpture of the prothorax is very peculiar, and 

 the dull sericeous surface extends upon the flanks to the pro- 

 sternum ; it is somewhat similar to that seen in Achryson, 

 less the punctures and hairs observed in that genus ; the smooth 

 dorsal line is rather broad, and abbreviated near the base ; there 

 is on each side a large cicatrix, commencing near the base, ex- 

 tending in front of the middle, then suddenly bent inwards 

 for a short distance, and then turning forwards is suddenly 

 abbreviated. They resemble, in position, the scars on the pro- 

 thorax of the % of some of our large species of Romaleum, but 

 are much broader. 



A female from Owen's valley, California, givenme by Dr. Horn, 

 differs from the male by the antennae shorter, thinner, and less 

 hairy ; the 5th ventral segment not truncate, and the Gth not 

 visible. The sides of the prothorax are finely punctured, but the 

 disk is shining, sparsely and coarsely punctured, and somewhat 

 uneven. 



There is great variation in the lateral spine of the prothorax ; in 

 the smaller $ it is quite absent, and the sides are rounded ; in 

 a large £ from California it is small and acute, in the $? it is 

 still more prominent. 



IIAPLIDUS Lec. (Cerambycini). 



Body elongate, slender, rather depressed, antennae, prothorax, 

 and legs thinly clothed with long flying hairs, of which a few are 

 also seen on the front part of the elytra ; front short, vertical ; 

 eyes large, emarginate, coarsely granulated ; geme short, very 

 acute ; palpi short, equal, last joint cylindrical, truncate. An- 

 tennae slender, scape a little shorter than the 3d joint, 4th about
