often vary considerably as shown by the fact that I have two 

 females from my first mentioned locality which are very much 

 larger in every way than typical forms, one 13 mm. long and 

 6 mm. broad, the other 15 mm. long and 7.5 mm. broad. 



Type male and female from Carrville, Trinity County, Cal- 

 ifornia, June 30, 1913, in my own collection, paratypes deposit- 

 ed in United States National Museum, California Academy of 

 Sciences, and Academy of Natural Sciences of Philadelphia. 



Chrysobothris laricis n. sp. 



Form and superficial appearance nearly that of fcmorata, sub-de- 

 pressed, piceous, with aeneous surface lustre, the punctured spaces of 

 the elytra cupreous, hody beneath, legs, antennae, and front metallic 

 green passing in places into cupreous ; antennae gradually more slender 

 to tip, third joint almost as long as the next two; front flat with two 

 oblique converging callosities between eyes ; clypeus rather broadly and 

 slightly angulately emarginate ; thorax with length two-thirds of 

 breadth, broadest in front of middle, sides almost straight for middle 

 two-thirds and slightly convergent posteriorly, more acutely near pos- 

 terior angles, and slightly rounded in front ; disc moderately convex, a 

 rather shallow and poorly defined median sulcus densely punctured, the 

 lateral boundaries forming slight callosities only anteriorly, a secondarv 

 elevation barely perceptible between this and sides and without cal- 

 losities, a well defined depression anteriorly near margin, the surface 

 coarsely and densely punctured. 



Elytra well rounded at humeri, gradually and but slightly arcuately 

 widening to posterior two-thirds, thence slightly arcuate and conver- 

 gent to individually rounded and serrate hind angles ; disc slightly 

 convex, the sutural costa poorly defined anteriorly but well marked 

 for posterior three-fourths and from middle backwards at first gradu- 

 ally diverging from suture then more widely and arcuately separating 

 and toward apex rather suddenly approaching again; the second and 

 third costae irregular, somewhat flattened in places and interrupted, 

 the fourth narrow, moderately well de-lined and near margin, all costae 

 more or less joined by various short cross bands, two well defined 

 slightly oblique and irregular transverse depressions, one slightly in 

 front of middle and the other midway between this and apex, simu- 

 lating closely those so generally seen in Chrysobothris fcmorata Fab.; 

 all depressions coarsely and densely punctured. 



Body beneath shining, densely punctured and pubescent on thorax, 

 more sparsely punctured on the abdomen, prosternum not lobed in 

 front. Anterior femora with a broad and obtuse tooth, feebly serrate 

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

 mm., breadth, 4.5 mm.
