240 THE CANADIAN ENTOMOLOGIST. 



almost throughout, disk feebly, evenly convex, punctuation moderately 

 coarse and close, with slight tendency to transverse strigosity. Elytra a 

 little wider than the prothorax, sides parallel for three-fifths their length, 

 then arcuately narrowed to apex, the tips separately rounded and serrulate; 

 surface somewhat uneven, but without costse or fovefe except the basal 

 impressions ; punctuation similar to that of the prothorax. Prosternum 

 coarsely, densely punctate, the flanks more sparsely so; abdomen sparsely 

 punctate and polished ; ventral segments without callosities, the last 

 segment with submarginal serrate ridge, the lateral margin interrupted but 

 not serrulate. Prosternum lobed in front, anterior femora toothed as 

 usual. Length, 6 mm. 



Oak Creek Canon, Arizona (Prof. Snow). ' 



Described from a single female (?) specimen. 



This species must be referred to Horn's Group VIII, and is most 

 nearly related X.q prasina; this latter, however, has the prothorax narrowed 

 anteriorly, the punctuation sparser, the last ventral without submarginal 

 ridge. 



Acmaodera robusta, var. nibrosuffusa, n. var. — In a series of 

 specimens taken by Dr. Fenyes at Mojave, Cal., the basal portion of the 

 disk of the elytra is broadly suffused with red. The prothorax is also 

 brightly bronzed, and the abdomen violaceous-bronzed, instead of black 

 as in the typical form. In this latter respect it approaches tuta, of 

 which, indeed, it might be considered a variety with about equal 

 propriety. 



Acmceodera ffepburnii, var. iatiflava, n. var. — This name is proposed 

 for a form of Hepburnii in which the elytra are entirely yellow except the 

 tip of the humeral urnbone, a narrow sutural stripe, and one or two small 

 spots at apical third. It looks so different from the typical form that it 

 would naturally be separated in a cabinet arrangement, and has, indeed, 

 been mistaken by collectors for a distinct species. It is known to me 

 from the Yosemite region and from various points in So. California. 



Acviceodera Bishopia?ia, n. sp.— Moderately stout, black, shining, not 

 at all bronzed, prothorax with or without a very small yellow spot at sides 

 near the base, elytra with numerous small irregular yellow spots, 

 pubescence long, fine, erect, fuscous and cinereous, the latter colour 

 predominating. Head densely punctate as usual, vertex finely carinate, 

 clypeal emargination rather deep, nearly as in labyrinthica. Prothorax 

 not wider than the elytra, twice as wide as long, widest a little before the
