North American RhyncTiophora. 237 



line with the lower margin of the eyes and at a distance before them 

 nearly equal to their own width. Antennae robust, shining, setose, 

 attached at anterior third ; scape robust, gradually and feebly clavate, 

 attaining the anterior portions of the eyes ; funicle robust, nearly one- 

 third longer than the scape, basal joint one-half longer than the second, 

 the latter slightly longer than the third, outer joints short, moniliform, 

 gradually wider, seventh wider than long ; club ovoidal, obtusely 

 pointed, moderate. Gular emargination rather deep and narrow. 

 Mentum moderate, slightly longer than wide, subtriangular, widest at 

 apex ; sides arcuate ; peduncle narrow but rather long ; maxillae 

 almost completely exposed at the sides. Emargination of genae small, 

 but rather deep. Mandibular scars rounded, rather prominent. 

 Prothorax subcylindrical, without trace of ocular lobes, but having a 

 very feeble line of small white setae, which are sometimes not at all 

 obvious. Scutellum small but distinct, more densely squamose and 

 slightly tumid. Humeral angles obsolete. Elytra not widely embrac- 

 ing the sides of the body. Legs moderate ; femora rather swollen ; 

 tibiae slender, slightly dilated at tip, the anterior not denticulate 

 within, the posterior with a widely separated double edge externally at 

 apex ; inner face slightly cavernous ; terminal spur small but distinct ; 

 tarsi finely and densely pubescent beneath ; basal joint elongate ; third 

 very strongly dilated, deeply bilobed ; fourth slender, elongate ; claws 

 moderate, free. Posterior coxae separated by slightly less than one- 

 half the total width. Metasternum rather long ; episterna narrow, 

 well defined ; suture distinct. First ventral suture strongly, 

 angularly arcuate for a short distance in the middle ; second segment 

 longer than the third and fourth combined. 



The obsolete ocular lobes and nearly obsolete fimbriae 

 together with the other characters above noted, seem to point 

 to a relationship with Barynotus Germ., but there are many 

 reasons also for considering it closely allied to the Amnesia 

 group of Ophryastini, the ocular lobes and fimbriae simply 

 having become obsolete. In fact, the ocular lobes appear to be 

 of very slight taxonomical value in some portions of the series. 



S. uniformis n. sp. — Form elongate-oval, convex, densely clothed 

 throughout above and beneath with small pearly-cinereous scales, with 

 excessively minute, whitish, subrecumbent setge on the upper surface 

 which form somewhat regular single rows on the elytral intervals, and 

 become longer, finer, and much more dense and erect on the legs and 

 abdomen. Head finely, feebly, very densely, and unevenly punctate ; 

 beak very broadly and feebly impressed along the middle. Prothorax 

 as long as wide : sides nearly parallel, broadly and distinctly arcuate, 

 very feebly constricted just behind the apex; base transversely truncate 

 about one-fourth wider than the apex ; the latter feebly sinuate in the
