A NEW SPECIES OF AGRILUS FROM CALIFORNL\.* 



BY W. S. FISHER, BUREAU OF ENTOMOLOGY, WASHINGTON, D.C. 



Among a collection of Buprestidse, submitted by Mr. H. E. 

 Burke for determinations, a large series of the following species 

 was found, which has been confused in collections with Agrilus 

 politus Sa>', and the description is presented at the present time, 

 so that the name can be made available for discussing this species 

 in economic papers. 



Agrilus burkei, n. sp. 



Form of politus, of a deep blue to bluish-green colour and 

 moderately shining. Antennae of a uniform blue or bluish-green 

 throughout, rather short, not reaching to the middle of the pro- 

 thorax, serrate from the fourth joint. Head nearly flat in front, 

 with a shallow, transverse groove at base of clypeus, terminating 

 in a deep pit just above the base of the antennae, a feeble median 

 depression reaching from the occiput to near the middle of the 

 front; front coarsely granulate, sparsely clothed with short, white 

 pubescence; occiput strigose. Prothorax wider than long, narrower 

 at base than apex; sides arcuate, feebly sinuate near the posterior
