One specimen, Oregon. Although evidently allied to the others 
in this division, the third joint of the antennæ is considerably nar- 
rower than the following ones : the curious reflexed margin of the 
anterior thoracie angles will easily distinghuish this species : the 
sides of the thorax are almost straight, slightly rounded at the apex, 
and before the basal angles : the first joint of the tarsi is slightly 
longer than te second.
