272 REVISION OF THE TE.VEBRIOXID.E OF AMERICA, 



This very beautiful little species may be readily known by the characters above given. 

 The narrow white margin of the elytra is equal to about a third of the width of each ely- 

 tron. The rounded elevated black tubercles contained in this white spare are much more 

 distinct than on any other portion of the elytral surface. Toward the suture they become 

 more flattened, their arrangement more confused and their boundaries very poorly defined, 

 so that they appear to range from one unto the other. 



V single specimen collected by D. rainier, in the Canon de ('belly, New Mexico, and 

 kindly placed at my disposal, through the Agricultural Bureau at Washington.

Two species from California belong here. Both are moderately elongate, depressed 

 insects, with surface very coarsely sculptured. 



into a long black stripe, as in haldemani. hi the former species the elytra have the Mack spots between the suture 

 and sides much larger and more numerous, while 1 1 1 1- similar region not only of the elytra but also of thorax in /<«Mr- 

 mani, is in major part white. The white patches of the under surface are larger in nodulosus and occur on each 

 side of the head, presternum, meso and metasternum, and first, second and third abdominal segments. In all cabinets 

 the name Z. haldemani, Salle, should be substituted for that ofZ. nodulosus, { Bald. 



Z. elega n s, similar in form to truth or concolor, but rather more slender; black, subopaque; thorax longer than 

 broad, broader in front, sides moderately rounded and gradually narrowing to base, surface moderately convex, with 



sparsely placed distinctly niuricatc punctures, each bearing a scale-like hair; margins with a narrow white space, in 



which arc included moderately elevated, smooth round black tubercles. Elytra elongate oval, narrower than the 



thorax, moderately convex and with nine rows of tubercles more confused and less distinct at the suture, and becom 

 in;,' more rounded, distinct and distant toward the sides, where there is a narrow band of white containing three, of 

 the rows of tubercles. Body beneath black and opaque, very sparsely punctured, each puncture with a scale. 



Length .60 inch.
