A recent rearrangenient of my somewhat extensive material in the 

 genus Baliininus, shows that we have been misinterpreting the species 

 described by Say under the name rectus, wliich, as identified in most 

 cabinets, is of slender form, with a thin and strongly arcuate rostrum, very 

 abundant in Arizona, and, as represented by closely allied species, 

 extending as far to the eastward as the Atlantic seaboard. The description 

 of Say shows that the true rectus has a long and almost perfectly straight 

 rostrum, bent downward only at tip. Two specimens from West Virginia 

 before me undoubtedly represent this species, which is not at all closely 

 related to the form wliich we have been calling rectus, but is more nearly 

 allied to t/uercus. :\ desire to rectify this very radical error is the principal 

 reason for publishing the following short study, in which quite a number of 

 other species, hitherto undescribed, are also made known. A few Tychiini 

 and related forms, believed to be new, are appended, in addition. Meas- 

 urements exclude the rostrum, the length of the latter being the distance 

 fronj the tip to the eyes in a straight line, or a chord of the arc.

 course nitidus, ainf>lus becoming a variety of nUidus and not a species, if that be 

 the true relationship between them. I may also add that there is no close 

 relationship whatever between dcniipfs awd .su/try/ini/riciis, and ihc latter is clearly 

 a distinct species.
