June, 1918.] NiCOLAY & WeISS : BuPRESTIS IN NORTH AMERICA. 101 



Holotype (J*) in the Nicolay collection and one paratype (^) in 

 the Weiss collection. Allotype (J) and one paratype (5) in the Leng 

 collection. Two paratypes (5 J*) in the Schaeffer collection. Tulare 

 Co., So. California. Dilley (Miss F. Dennis) Oregon. 



This species has long been placed in collections under the name 

 gibbsi. How it was originally identified as this insect is a puzzle as 

 there is not the slightest resemblance between it and Le Conte's de- 

 scription and figure (Report of Pacific Exploration, 1857, Plate I, 

 fig. 17). It is distinct from all other members of the group and 

 could never be mistaken for anything else. On oak (Van Dyke). 



Buprestis gibbsi (Le Conte), 57-42. 



Elongate parallel. Elytra purplish with anterior pale spot extending: 

 obliquely to the base and enveloping the humeral callus, another transverve 

 spot just behind the middle not attaining the suture but extending to the 

 margin and a subapical spot extending nearly to the suture and dilated along 

 the margin ; the last two spots always touched laterally with orange. Striae 

 deep, punctate, the intervals sparsely punctate. Antennae testaceous, the first 

 joint senescent. Head purplish, punctate, the front carinate, base bisinuate. 

 Pronotum more or less evidently impressed along the middle, sides parallel 

 to slightly arcuate. Length 15 mm.

 Yosemite Valley, June 14, elev. 4000 to 5000 ft. (Mason) ; Sequoia; 

 Station, Tulare Co. (Hopping) ; California. Corvallis (Chamber- 

 lin) ; Oregon. Manitou, July 6 (Neubarth) ; Colorado. Steilacoom 

 (Gibbs) ; Washington. 



Not common, found occasionally on oak and poplar and. probably 

 breeds in these trees (Chamberlin). On black oak and black cotton- 

 wood (Burke). The above description was copied from Casey's 

 translation of Le Conte with slight alterations and additions. Gibbsi 

 is practically unknown in eastern collections. However Mr. Frank 

 Mason of Philadelphia is fortunate in possessing two females. This 

 species can be readily distinguished by the purplish elytra and the 

 yellowish posterior spots being touched with orange, a character that 

 is not clearly brought out in Le Conte's description.
