CRYPTOCEPHALUS IN AMERICA NORTH OF MEXICO 13 subspecies described by Schaeffer (except paratypes of snovn in Kansas University) are now in the National Museum; some of these were clearly designated on labels by Schaeffer as types, but some were not; others have been designated (apparently by Barber) as cotypes and, it would appear, occasionally in error. This situation is complicated by the incomplete type data appearing in Schaeffer's original descriptions; rarely is the number of specimens given from which the species was described, and generally only a portion of the label data was published. In some cases, the label data as it appeared in print was altered from its original form or miscopied, and in some cases, even, more data were given than now appear on the labels. In general, the type designations adopted by Barber have been retained; changes have been made in these only when there was no doubt in my mind that an error had been made and that a change was warranted. I have selected lectotypes for those species for which a type has not previously been designated. Taxonomic charactersâThe system of terminology employed here in naming and numbering the elytral striae and intervals requires explanation. All North American species possess a short series of punctures in the scutellar region that are called the scutellar stria (fig. 1); this does not extend beyond the middle of the elytra. The numbering of the striae begins with the next row of punctures (the first row of the apical half of the elytron) and continues to the side before the lateral margin. The regular series of punctures at the lateral margin is termed the marginal stria; this normally extends from the base to the apex of the elytra. The scutellar and marginal striae are referred to only by their names. Thus the inner and outer rows of punctures referred to in the key are the first and last rows of numbered striae.
