Extract

Liparocephalus cordicollis, Lec.—This species does not differ in any way from L. brevipennis, Mæk., except in its pale colour, and the two forms must be united, as intimated in a former paper (Can. Ent., XXIV., 158). Since the publication of that paper more than thirty examples of brevipennis and several of cordicollis have been examined and compared. Apart from colour, not a single character of general applicability has been observed by which to separate them into species. The synoptic characters given by Capt. Casey (Ann. N. Y. Acad. Sci., VII., 354) are without value otherwise than as descriptions of those of some individuals. When a sufficient number of each form is present, all the elements, without exception, tabulated by him to differentiate cordicollis exist in examples of brevipennis, and the reverse.
