I, 1913, collected on Pinus ponderosa Doug]. by myself, in 
niy own collecticn; one paratype deposited in Academy of 
Natural Scienees of Philadelphia. 
Chrysobothris falli n. sp. 
Form and appearance nearly that of C. caurina Horn, sub-depressed, 
upper surface piceous with cupreous punctate areas, head, sternum 
and femora, viridocupreous, tibiae and abdomen with a greenish purple 
lustre; antennae gradually more slender towards tip, third joint as long 
as the next two, front flat, coarsely, somewhat cribrately punctate. 
with two small callosities between eyes, and clothed with fine white, 
erect pile, clypeus triangularly emarginate, with sides of emargination 
rounded externally; thorax with length two-thirds of breadth, with 
sides slightly divergent forwards from base, sinuate at middle, and 
obliquely constricted towards anterior angles, disc moderately convex, 
a rather shallow though well defined median sulcus densely punctured, 
a flat but irregular callosity bounding it on either side and extending 
from base to apex, two irregular callosities, one anterior and one 
posterior, between this latter and sides, the surface otherwise moder- 
ately densely punctured, and with a small amount of white pile at the 
sides; elytra well rounded at humeri, with sides somewhat parallel from 
in front to beyond the middle, thence slightly arcuate and convergent 
to hind angles, disc slightly convex, the sutural costa well defined, 
broader and flatter in front, narrower and cariniform posteriorly and 
from middle to apex almost straight and but slightly diverging from 
suture, the second costa less elevated and defined, but interrupted one- 
third from base and one-third from apex, the third only evident in 
median portion of elytra, the fourth feeble, all the costae joined by 
certain irregular, flat, smooth and transverse areas which are more or 
less aggregated or joined into transverse bands, especially just back 
of base, at middle, and towards apex, the depressions all coarsely and 
densely punctured, and like the elevations, with a tendency to be 
formed into transverse belts as is the case one-third distant from the 
base and one-third from apex; body beneath shining and quite smooth 
posteriorly; prosternum slightly lobed at middle in front, quite densely 
punctured, and moderately pilose; anterior femora with a broad obtuse 
tooth, serrulate on outer edge; last ventral with its margin serrulate. 
Length 11 mm., breadth 4.5 mm. 
6. Prosternum more finely and densely punctured; anterior tibia 
arcuate, rather abruptly dilated at tip, the dilatation being a lamina 
arising from the posterior side about one-fourth distance from apex 
and gradually arcuately widening until near apex where slightly notched, 
obliquely truncated at apex; middle tibia less arcuate, gradually broader 
from apical third to tip, the posterior tibia straight; last ventral seg-
