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. 



49O. Eu. villicornis. Saturate testaceus, thorace ( $ ) opaco, 

 subtilissiine~"alutaceo et subsericeo, latitudine breviore, lateribus valde 

 rotundatis, linea dorsali laevi, cicatrice vix elevata, sublunata utrinque 

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

 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- 

 sternuin ; 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, given me by Dr. Horn, 

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

 hairy ; the 5th ventral segment not truncate, and the 6th 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. 



HAPJLIDUS LEG. (Cerambycini). 



Body elongate, slender, rather depressed, antenna, 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 ; genae short, very 

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

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