Eagle Harbor, Mr. Rathvon. Very similar in appearance to S. buprestoides, but the 

 form of the thorax is different. The posterior tibia; are scarcely dilated at the end. 



31 C. gibbulus. — Niger pubescens, thorace oblongo, modice elevato, confertissime 

 punctato, elytris confertim subtiliter punctatis, basi subgibbosis, gibberis minus eleva- 

 tis, ante medium rufis, lineis 2 obliquis apiceque densius cinereo-villosis : antennarum 

 articulo l^o tarsisque rufis. Long. -27. 



Very similar to C. verrucosus, but the thorax is less elevated and the elytra more 

 distinctly punctured and mucli less gibbous : the S^fl joint of the antenna; is not arm- 

 ed with a spine: in the markings there is no difference, except that the. cinereous lines 

 are less oblique. 



•^2 JE. despectus. — Niger cinereo-pubescens, supra punctis pluribus nigro-pubescenti- 

 bus variegatus, thorace transverso Irovi, basi abrupte constricto, serieque transversa, 

 punctorum notato ; elytris apice truncatis macula oblonga sublaterali versus medium 

 fasciaque angulata pone medium nigris. Long. '41. 



The antennte and posterior tibia; are annulated, the former in both sexes but little 

 longer than the body : the femora have one or two black spots. It is found everywhere ; 

 the ? has the anal segment elongate and truncate. 



•^3 P. penicillatus. — Cylindricus, niger dense cinereo-pubescens, thorace lateribus 

 spinoso, disco valde tuberculato, calloque parvo pone medium elevato, confertissimfi 

 punctulato, elytris apice truncatis, cinereo, fuscoque variegatis, fascia lata ante medium 

 alliida ; 3-carinatis, carina 1 ^^ pilis longis nigris fasciculata, interstitiis minus dense 

 punctatis. Long. •27. Pic. The antennaj and feet are annulate. 



I am doubtful if the next species (Tetraopes) is found at Lake Superior. 



3-* S. adspersa. — Nigra, ochraceo dense pubescens, thorace latitudine sesquibrevi- 

 ore, grossius ocellatim punctato, punctis nigris ; spatio utrinque fere ad apicem es- 

 tendente minus dense pubescente ; elytris postice subangustatis, sutura acuminata, 

 sparsim grosse nigro-punctatis, hue illuc spatiis densius pubescontibus, quorum unum 

 mox pone medium oblique versus suturam ascendit. Long -9. 



Very close to S. calcarata, but the color differs, and the thorax is shorter. 



35 S. moesta. — Nigra cinereo-pubescens, grosse confertim punctata, thorace latitu- 

 dine vix breviore, basi leviter angustato, cinereo-bivittato, elytris apice rotundatis, an- 

 tennis corpore brevioribus annulatis, basi nigris. Long. -5. Pic. 



The claws are entire, although at first view it would seem to be a Phytoecia; the 

 head has a black, finely impressed frontal line. The eyes are almost divided.
