119. Centrinus lineellus, breviter fusiformis, niger, subtus squamulis 

 ocbreis argenteo-nitentibus dense tectus, rostro thorace longiore, arcuato, apice 

 remote subtiliter basi fortiter punctato, linea media lsevi, capite nudo parce 

 punctulato, thorace dense punctato, nigro-squamoso, vittis tribus latis ochreo- 

 squamosis, elytris nigro-squamosis, profunde striatis, vittis duabus integris 

 intermediaque basali ochreo-squamosis. Long. "12. 



One specimen, Tejon. The inner vitta occupies the whole of the 2nd 

 interval and the 3rd from the apex to within one-fourth of the base : the 

 short basal vitta is on the 4th, and extends about one-sixth of the length : 

 the external vitta covers the 6th interval to the middle, then occupies the 7th 

 and 9th : a few scattered yellow scales are seen near the margin. The com- 

 missures of the abdomen and the coxa? are black. The feet are sparsely 

 clothed with scales. 



120. Sphenophorus subcarinatus. 



121. Sphenophorus simplex, niger, subnitidus, rostro cylindrico, sub- 

 tiliter punctato, ad basin canaliculate, capite lsevi, thorace oblongo, latitudine 

 longiore, lateribus late rotundatis, ad. apicem subito constricto et tubulato, 

 fere aequaliter punctato, ante scutellum obsolete impress, et paulo grossius 

 punctato, elytris striis profundis externis punctatis, interstitiis alutaceis 

 planis subtiliter parce punctulatis, tibiis anticis intns late sinuatis, posteriori- 

 bus intus unidentatis et fimbriatis, antennis piceo-rufis. Long. -32 -36. 



Tejon. Varies with the legs reddish yellow. The small punctures of the 

 intervals of the elytra are irregular on the sutural and alternate spaces, but 

 form a single series on the second and alternate spaces : the external striae are 

 distinctly punctured ; the interior ones appear smooth, but with a powerful 

 lens they are seen to be slightly punctured. 



121. Callidium b 1 a n d u m , elongatum rufo-testaceum, parce breviter pal- 

 lide pubescens, thorace latitudine vix breviore antice parum, postice distincte 

 constricto, lateribus rotundatis, parce punctato, elytris obscure cyaneis con- 

 fertim punctatis, abdomine nigricante, antennis obscuris basi runs. Long. -25. 



Tejon. Closely allied to C. a m ce n u m Say, but is narrower, with the elytra 

 more densely punctured, the abdomen blackish, and the feet entirely rufous. 



122. Callidium obscurum, fusco-nigrum, haud nitidum, pilis fuscis 

 suberectis vestitus, capite thoraceque confertissime punctatis, hoc longius 

 parce piloso, lateribus rotundatis, postice angustiore, linea obsoleta dorsali, 

 calloque postico hevibus, elytris parce punctatis, punctis ad basin grossis, 

 postice subtilibus, femoribus valde incrassatis, tibiis parce longe pilosis* 

 Long. *48 - 55. 



Tejon. Allied to C. dimidiatum, but from its larger size and uniform, 

 color it looks like a Tetropium. y
