lieve, been so referred ; the other, a dark bronzed form, is 

 more like lecontei, and has so passed, but it is larger than that 

 species, and in some other respects quite different. The fol- 

 lowing descriptions and notes will help to make these fine Bu- 

 prestides better known to our collectors and students of our 

 Coleoptera. 



Trachykele opulenta n. sp. 



Green of varying brilliancy and with more or less evident golden or 

 coppery glints at some part of the surface ; disk of elytra maculate with 

 small velvety black spots which vary much in size and number, but which 

 show a tendency toward arrangement in longitudinal lines extending 

 from the basal to the apical fourth. Upper surface glabrous and ex- 

 tremely densely not coarsely punctate ; beneath with fine rather sparse 

 whitish pubescense, densely punctate anteriorly, apical portion of abdo- 

 men more sparsely so. Front uneven, vertex impressed each side, car- 

 inate at middle. Prothorax nearly one-half wider than long, the length 

 subequal to the width at apex, base a little wider, sides (superior lateral 

 crest) broadly but distinctly angulate just behind the middle, disk with 

 three anterior impressions and two large and deep posterior ones, the 

 median lines sometimes narrowly smooth posteriorly and terminating in 

 a small antescutellar fovea. Elytra about four times as long and one-third 

 wider than the prothorax, humeri rather prominent ; sides parallel to be- 

 hind the middle, thence gradually narrowed ; apex narrowly subtruncate 

 and a little oblique ; disk with from one to three short or incomplete 

 sulci parallel with the suture, one or all of which may become nearly or 

 quite obsolete. Sterna and first ventral segment very densely punctate 

 and dull, following segments more sparsely finely punctate and shining, 

 especially at middle. Length, 16-20 mm.; width, 5-6^ mm. 



In the male the antenna? are a little longer than the head and pro- 

 thorax ; the front and middle tibiae are slightly curved and denticulate 

 within, and the fifth ventral is squarely truncate. 



In the female the antemue scarcely pass the base of the prothorax ; the 

 tibiae are nearly straight and denticulate within, and the fifth ventral is 

 rotundate-truncate. 



Hab. South Central Sierras of California to Washington 

 (State). I have seen six examples (i 9 , 5 s) of this beauti- 

 ful species, all but one of which were taken by Mr. Ralph 

 Hopping in the Giant Forest region, Tulare Co., California. 

 Of these Mr. Hopping writes, "One was beaten from the foli- 

 age of Pinus lamberliana at 6,000 ft.; others were caught fly- 

 ing in the Giant Forest at 6,400 ft., and one was cut from the 

 burnt standing mast of a Libocedrus decnrrcns (Incense Cedar)
