later placed scripticollis as a variety of vians, and gave its locality 

 as Hudson Bay and Slave Lake. Say's distinction of vians and 

 scHfticoUis on the basis of the frontal spot does not hold, as this 

 spot is common to both. The sinuate thoracic markings appear to 

 accompany a deeper and coarser punctation, and such specimens are 

 duller. It also seems to be a more northern and western form, occur- 

 ring in Colorado, Kansas, Missouri, Alberta, Michigan, and New York, 

 although one specimen is labeled from as far south as Fort Monroe, 

 Va. The southern specimens of viam^ have lighter punctation, in 

 some cases are almost smooth, and are more shining. A series from 

 Florida has the punctures obsolete and is brightly shining with 

 metallic luster. The thoracic band in these is widened to cover 

 nearly all of the pronotum with scarcely any visible lighter anterior 

 margin. 



W. S. Blatchley reports finding Oe. vians in Florida on oak, and 

 R. A. Cushman bred it from the " stem of Polygonutn pennsylvani- 



There are two other specimens in the National Museum that I 

 have placed with doubt as the following variety of vians: 



OEDIONYCHIS VIANS BADIA, new variety 



Head and prothorax similar to those of vians. Elytra deep reddish 

 brown and coarsely punctate, punctation coarser and shallower 

 than the punctate form of vians and resembling the punctation of 

 Oe. -finihriata. Elytra not dull as in punctate form of viaris^ but 

 moderately shining; surface not alutaceous. Elytra shorter than in 

 typical vians and markedly more rounded at apex. Beneath, epi- 

 pleura and abdomen pale, the latter with deep brown area in middle. 



Length. — 5 to 5.2 mm. ; width, 3 mm. 



Type and paratype.—C2ii. No. 29155, U.S.N.M. 



Type locality. — Fort Monroe, Va. (E. A. Schwarz). 



The specimens were originally placed in the collection with 

 Oe. fiTnbi^ta, but they diifer from that species in shape of prothorax 

 and elytra as well as in markings.
