 the female is distinctly ovate.

 Kansas, in the valley of Platte Eiver. Smaller and narrower than the preceding, 

 and readily known by the strongly rounded sides of the thorax. 



10. S. mixta, oblonga, testacea subopaca griseo-iridescens, margine longe fimbriata, clypeo dense punctato, 

 antice subrotundatim truncate, tborace lateribus antice magis rotundatis, subtilius punctato, elytris parce 

 punctatis, striatis, interstitiis alternatim latioribus et magis punctatis, pectore villosulo. Long. -34. 



San Diego, California. Larger and narrower than the next, but smaller than S- 

 fimbriata, and differing from both by the clypeus being almost rounded in front 

 without distinct lateral angles, as well as by the form of the thorax. The breast is 

 more hairy than usual, though less so than in S. fimbriata, and the hind coxae are 

 nearly glabrous. 



11. S. alternata, oblongo-ovata convexa, purpureo-picea, iridescens, clypeo dense punctato, antice latius 

 subemarginato, et reflexo, tborace punctato lateribus oblique magis rotundatis, parce fimbriatis, elytris 

 punctatis, striatis interstitiis alternis conspicue latioribus, et magis punctatis, lateribus fimbriatis, pectore 

 parce villosulo. Long. -28—34. 



San Diego, California. Of the color size and form of S. sericea, but the thorax 

 is broader, more rounded on the sides and more strongly fringed : the elytra are less 

 deeply striate, with the punctures more equally scattered over the interstices. 



12. S. antbracina, brevius ovata, convexa, atra opaca, paulo iridescens, clypeo confertim punctato, 

 antice vix emarginato, reflexo, thorace punctato, lateribus oblique magis rotundatis parce fimbriatis, 

 elytris punctatis, subtiliter striatis, interstitiis planis, pygidio fortius punctato, coxis posticis dense punc- 

 tatis. Long. -36. 



Oregon, Dr. Townsend, and others. 



13. S. frontalis, breviter ovata, picea, subnitida, paulo iridescens, clypeo confertim punctato, marginato, 

 antice subemarginato, fronte inter antennas linea elevata in vertice subangulata notata, thorace punctato, 

 lateribus oblique magis rotundatis, parce fimbriatis, elytris parce punctatis fortius striatis, pygidio sub- 

 tiliter punctato, coxis posticis parce fortiter punctatis. Long. •27. 



One specimen, Oregon, Col. M'Call. Closely related to the preceding, but seems 

 to differ in the slight transverse angulated frontal line, and the sparsely punctured 

 posterior coxae ; the elytra are more deeply striate but less punctured, and the pygidi- 

 um is more finely punctured. 



14. S. r e b u s t a, breviter ovata, nigra, nitida, subiridescens, clypeo confertim punctato, marginato, antice sub-
