Hosts. — Adults have been reared from Utah juniper (Juniperus 

 utahensis (Engelmann) Lemmon) and Arizona cypress (Cupressus 

 arizonica Greene) collected in Arizona, and from the eastern red cedar 

 {Juniper-us virgmiana Linnaeus) collected in Nebraska, and this 

 species has been recorded by Burke (1918) as breeding in the bark 

 and wood of dead and dying Rocky Mountain red cedar {Juniperus 

 bcopulomm Sargent) in Colorado. 



The sculpture on the dorsal surface of the body is rather constant, 

 but some specimens are more cupreous than others. The smooth spots 

 on the front of the head are usually present, but occasionally speci- 

 mens are found without the spots. The pronotum is usually widest 

 along the middle and arcuately converging at the base and apex, but 

 in some of the specimens examined it is widest at the apical fourth, 

 with the sides obliquely converging posteriorly, and the disk is with 

 or without a faintly indicated sulcus,, and occasionally with from one 

 to four indistinct, smooth spaces. The prosternum is always broadly 

 rounded in front and usually the median lobe is distinct, but in a 

 few examples it is scarcely indicated. The lateral callosities on the 

 abdominal sternites are not elevated, and frequently are indistinct. 

 The length is from 8 to 13.5 mm.
