at the base of the dilatation ; pygidium coarsely punctate, subcribrate 

 near the edge, which is irregular from the coarseness of the sculpture. 

 The clypeal emargination is quite deep and of a form somewhat sug- 

 gestive of that of femorata. The second and third specimens in the 

 LeConte series are females, similar in size (one even larger) and 

 appearance to the male type and probably identical with it. In one 

 of them the eyes are as widely separated as in the type, in the other 

 rather less so ; the clypeal emargination also shows less approach to 

 the femorata type. They are labeled simply " Cal." The fourth 

 specimen is the type of vulcanica Lee. which Horn suppresses as a 

 small form of calif ornica. It is evident that in making this state- 

 ment Horn had in mind the large size of typical calif ornica, but as 

 the length of vulcanica is 15 or 16 mm. and the measurements given 

 by him for calif ornica are 10-19 mm., the force of the remark is not

apparent. It is by no means certain that vulcanica is the same as 

 calif ornica, but it must go as placed until males have been properly 

 associated. The type is a female without antennae or front legs; it 

 resembles calif ornica considerably but the prothorax is more densely 

 rugosely sculptured, the smooth spaces each side of the median 

 groove are encroached upon by the punctures and are therefore small 

 and not very well defined; the sutural costa of the elytra is obsolete 

 in fully basal half and the other costse are even more undeveloped. 

 The eyes are a little less distant than in californica, the prosternal 

 margin not lobed, though faintly more prominent at middle. The 

 last ventral is rounded at apex without trace of an emargination, 

 probably an accidental variation. The specimen is from Oregon.
