ings, more confluent than in lincata. It seems to ht a distinct 

 geographical race and as no specimens of the true lincata were taken 

 in the same locaHty, we believe the form should receive a varietal 

 name. 



Buprestis nuttalli (Kirby), 37-152. 



" Body black-bronzed, glossy, punctured ; underneath with a few pale 

 decumbent hairs. Head confluently punctured with several irregular con- 

 nected levigated spaces ; labial palpi, spots on the mandibles, labrum, lower 

 margin of the eyes and frontal spots yellow. Prothorax bisinuate both at the 

 apex and base, grossly punctured with several levigated spaces ; lateral margin 

 except the base and parts of the anterior yellow, elytra slightly furrowed, 

 furrows punctured, interstices alternately convex and plane, the sutural one 

 is convcxed and forked at the base, the flat ones are most punctured but the 

 convex ones more grossly ; in the disc of the elytra are three equidistant ir- 

 regular yellow spots arranged longitudinally, and nearer the base, on the 

 second ridge a line of confluent yellow dots : the apex of the elytra is trun- 

 cated ; on each of the ventral segments of the abdomen the sides are marked 

 with a triangular orange-colored spot, those on the anal segment being larger 

 and irregular: the coxae also and tmderside of the thighs are partly of the 

 same color. 



" Variety B. Without the yellow line of confluent dots at the base of 

 the elytra and with the spots arranged longitudinally indistinct. 



" C. With all the ventral orange spots large and irregular. 



" D. Front with a large central spot. Base of the belly bluish. 



" E. Elytra without yellow spots. Front as in D. 



" F. With only one distinct yellow spot. 



"Length 15-17 mm. (Latitude 65 and Rocky Mts.)"

The above original description is presented in order to clear up 

 the now existing confusion in correctly identifying the true nuttalli, 

 which is strictly a northern species. The elytra varies in color 

 from black with a distinct greenish tinge to plain black. This species 

 can be separated by the rounded pronotum and the spots at the side 

 of each abdominal segment. The yellowish markings of the head 

 are variable and cannot be relied upon ; the lateral margins of the 

 thorax also vary from entirely yellow to black with just the anterior 

 tips yellowish. Tip of abdomen is truncate in the female without 

 prominent teeth.
