COLEOPTERA. 453 



OxuRA, Kirb. 



The body is narrow and elongated; the thorax longer than it is 

 "wide, ovoid, and truncated at both ends; and the intermediate joints 

 of the antennse long and cylindrical(l). In 



AcANTHOMERA, Lat. — PimeUci, Fab. 



The thorax is almost orbicular and transversal; the abdomen nearly 

 globularj the third joint of the antennae cylindrical and much longer 

 than the following ones, which are almost of the same form, and the 

 three last at most granose(2). 



MisoLAMPus, Lat — Pimelia, Herbst. 



Where the thorax is almost globular and the abdomen nearly 

 ovoid; the third and fourth joints of the antennas are equal, and cy- 

 lindrical, the eighth and two following ones a little stouter, almost 

 turbinifomn, and the eleventh or last larger and ovoid(3). In 



Blaps, Fab. 



Or Blaps properly so called, the thorax is almost square and 

 plane, or but slightly convex. The abdomen is oval, truncated 

 transversely at base, and more or less elongated. The elytra of 

 most of them are narrowed and prolonged into a point, those of the 

 males especially. The third joint of the antennas is cylindrical and 

 much longer than the following ones; the latter, or at least the three 

 antepenultimate ones, are granose; the last is ovoid and short. 



With those species in which the body and abdomen are propor- 

 tionally less elongated and wider, in which the elytra of the females 

 terminate in a very short point, and where the thorax is almost 

 plane, are arranged the 



B. mortisaga, Oliv., Col., Ill, 60, 1, 2, 6; Tenebrio mortisa- 

 ga, L. Length, ten lines; black, but slightly lustrous; smooth; 

 simply punctured above; thorax almost square, offering on each 

 side of its posterior margin vestiges of a small flattened border; 

 extremity of the elytra forming a short and obtuse point. In 

 dark and filthy localities near privies, and frequently in houses.
