widely flattened out and wrinkled internally, with a strong 

 oblique ridge from each shoulder to beyond the middle, and 

 a shorter straight one towards suture ; suture itself somewhat 

 elevated, with small punctures scattered about, and some irre- 

 gular rows of large ones. C luler surf (ice with irregularly dis- 

 tributed punctures. Leys long ; femora stout ; front tibiae with 

 five external teeth, and in the middle of the inner edge four 

 smaller ones; four hind tibiae each with two small sharp teeth, 

 slightly in advance of the middle, and with some smaller ones. 

 Length (including mandibles) 25 mm.

The lower parts of the head are somewhat as in R. juyularis 

 and B. parallelus, but very different from those of R. nehulo- 

 siis. It is certainly the finest species of the genus. The 

 extreme base of the head of the type is without punctures or 

 gloss, and has a median fovea, but is probably usually con- 

 cealed. Each mandible has a strong tooth at the apical third 

 on the upper surface, and two somewhat smaller median ones 

 on the outer portion of the upper surface. The right one has, 

 internally, four large, blunt, simple teeth, and three double 

 or semi-double ones; the left mandible has five simple and two 

 semi-double ones. The maxillary palpi are long, the first visible 

 joint curved, and about as long as the two others combined. [The 

 labial palpi are missing from the type.] There are a few straggling 

 hairs or setae on the mandibles.

cf . Of a rather bright flavous-red, metasternum inf uscate ; 

 head and four large elytral spots deep purplish-blue, almost 

 black. Clothed with long, straggling, upright dark hairs. 



Head with dense punctures. Antennae extending to apex 

 of basal spot on elytra, first joint stout and curved, second 

 slightly longer and thicker than first, with a spiniform process 

 at apex, eleventh almost twice the length of tenth. Prothorax 

 decidedly transverse, finely rugose, apex much wider than 

 base. Elytra at extreme base scarcely wider than apex of pro-
