56 ENTOMOLOGICAL NEWS. [Feb., 'l8 



I, 1913, collected on Finns ponderosa Dougl. by myself, in 

 my own collection; one paratype deposited in Academy of 

 Natural Sciences 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 ii mm., breadth 4.5 mm. 



$. 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-
