Saperda hornii Joutel 



This species [pi. 7, fig. 3] has been mistaken for S. mutica, 

 but can be easily separated from it by the first joint of the 

 antennae being normal in size and also by the fact that the last" 

 abdominal segment of the female has a deep longitudinal im- 

 pression along the middle of the upper side, while mutica 

 has that part convex. The punctures of this insect are also much 

 larger and deeper, and fewer in number. 



Some specimens have lost the yellow marks an'd are entirely gray. 



Distribution. Oregon, Los Angeles Cal., 1 Humboldt county, 

 Cal., Nevada county, Cal., Yosemite Cal., Goldendale Wash.

 layer of light yellowish gray hair, lighter beneath, and diversi- 

 fied above with irregular blotches and streaks of dark yellow 

 arranged on the elytra in broken and irregular longitudinal 

 lines, the line nearest the outer margin and just below the 

 humeral angle unbroken except by the punctures, and continu- 

 ing nearly to the tip. Elytra obliquely narrowed at apex. 

 Thorax cylindric, sometimes slightly narrowed in front, with a 

 longitudinal stripe of dark yellow hair on each side and on top, 

 under side yellow. Scutellum yellow. Entire insect covered 

 by rather large and deep punctures, slightly smaller beneath. 

 Head : hairs yellow, changing to gray at labrum. Legs and under 

 side of body light yellowish gray with glabrous punctures. An- 

 tennae annulate except first joint, which is entirely gray and 



*In the original description, the locality of the type male in the national 

 museum was wrongly given as Yosemite Cal. It should be Los Angeles 

 Cal.
