many years ago by myself. There is practically no variation. 

 The type male and female, Tuolumne County, California, 

 June 14, 1914, in my own collection, one paratype deposited 

 with United States National Museum and another with Cali- 

 fornia Academy of Sciences. 



Chrysobothris pseudotsugae n. sp. 



Form nearly that of fcmorata, sub-depressed with aeneous surface 

 lustre, the punctured spaces of the elytra a greenish bronze, body be- 

 neath, legs, antennae, and front a brilliant green ; antennae gradually 

 more slender to tip, third joint as long as the next two, front flat with 

 two callosities between eyes, clypeus rather broadly and semicircularly 

 emarginate ; thorax with length two-thirds of breadth, sides almost 

 parallel for middle two-thirds, slightly convergent near posterior angles 

 and more convergent and rounded in front, disc moderately convex, 

 a rather shallow though well denned median sulcus densely punctured, 

 an irregular elevation on each side, broader and distinctly denned in 

 anterior half, narrower and illy denned posteriorly, a barely perceptible 

 parallel elevation between this and sides with anterior and posterior 

 portions slightly denned as callosities, the surface otherwise densely 

 and coarsely punctured. 



Elytra well rounded at humeri, parallel for middle two-thirds, thence 

 slightly arcuate and convergent to individually rounded and serrate 

 hind angles, disc slightly convex, the sutural costa well denned, broader 

 and flatter in front, narrower and cariniform posteriorly and from 

 middle to apex slightly but perceptibly diverging from suture ; the 

 second costa beginning near base in a broad and flat callosity, then 

 interrupted but just anterior to middle continued again but as a nar- 

 row elevation to near apex, the third and fourth costae forming irreg- 

 ular and oblique zig-zag elevations; all costae joined by certain irreg- 

 ular flat and transverse elevations, especially in posterior half, depres- 

 sions all coarsely and densely punctured. 



Body beneath smooth and shining, sparsely and coarsely punctate 

 on thorax and sparsely and finely on abdomen, prosternum not lobed 

 in front. Anterior femora with a broad and obtuse tooth, feebly ser- 

 rate on its outer edge; last ventral with its margin serrulate. Length, 

 ii mm.; breadth, 4.25 mm. 



$. Prosternum not densely punctured and sparsely pubescent; an- 

 terior tibia arcuate, rather abruptly dilated at tip, the dilatation bcin- 

 a lamina arising from the posterior side about one-fourth distance 

 from apex and forming an elongated trapezium ; middle tibia less 

 arcuate, gradually broader from apical third to tip, the posterior tibia 

 straight ; last ventral segment broadly semi-circularly emarginate, the 

 last dorsal sparsely punctuate with a triangular emargination.
