with an appressed blackened spine; penis-guard conspicuously narrowed

Holotype, cf , Monterey County, California, July 22, 1896. 



Paratype, tf, Juliaetta, Idaho, May 3, 1904. Type in the

This new species seems to be about as common as the only 



other western species of the genus, Ptychoptera lenis O. S. 



The two species are closely related but may be separated by 



the following key: 



Size larger (male, wing over n mm.); abdominal tergites black, including 

 the hypopygium; lobes of the ninth tergite of the male hypopygium 

 with a subapical black appressed spine on the ventral surface. 



P. lenis O. S. 



Size small (male, wing under 9 mm.); abdomen with the sides of the ter- 

 gites and the hypopygium reddish; lobes of the ninth tergite of the

Notes on Buprestidae with Descriptions of New 



Species (Coleop.)- 



By JOSEF N. KNULL, Bureau of Plant Industry, Harrisburg, 



Pennsylvania. 



The following is a list of host-plants and emergence records 

 of Buprestidae collected by the author and reared at Hum 

 melstown, or Harrisburg, Pennsylvania. In all cases, the 

 material was caged under out-of-door conditions. 



Chalcophorella campestris Say. At Harrisburg, Pa., ninety living 

 adults were chopped from their pupal cells in a dead beech (Fagux inucri- 

 cana) about 14 inches in diameter on March 13, by Mr. H. B. Kirk and 

 the author. The adults, which appear in the spring, transform in ihc 

 fall and pass the winter in the pupal cells. The species was also reared 

 from dead willow (Salix nigra) and buttonwood (Platanus occidentalis) . 



Buprestis rufipes Fab. Pupae of this beetle were observed in the 

 heart-wood of a dead American elm ( Uliinix <nncricana) at Hummelstown, 

 Pa., June 28, and on July 10 the adults were mature. Adults \vcn- also 

 reared July 5 from the wood of a dead sour gum (Nysxa xylniticn] col- 

 lected at Hummelstown, Pa. Beetles were also reared from dead beirh 

 (Fagus americand) and hickory.
