32 MEMOIRS ON THE COLEOPTERA 



all those mentioned, in the absence of a basal white spot on each 

 elytron : 



Cicindela lincolniana n. sp. Rather stout, the hind body relatively 

 still broader than in knausi, blackish-brown, the anterior parts faintly 

 subcupreous; under surface black, sometimes with faint metallic lustre, 

 rather conspicuously broadly albido-pubescent toward the sides, all the 

 trochanters testaceous; head moderate, very finely strigilate, sparsely 

 pubescent, the eyes very prominent; labrum with a short and small but 

 evident median tooth; prothorax small and about as long as wide (cf ), or 

 larger and slightly transverse (9 ), narrower than the head, parallel, with 

 nearly straight sides; surface minutely rugulose, sparsely puberulent 

 toward the sides and along the middle; elytra large, more than twice as 

 wide as the prothorax, subparallel, the sides feebly arcuate, obliquely 

 arcuate at apex, with outer just visible sinuation (cf), or with the outer 

 sinuation deep and defined anteriorly by an obtuse but very sharp pro- 

 jecting angle (9 ), the combined apex acute and minutely denticulate in 

 both sexes, the serrulation obsolete or very nearly so; surface alutaceous, 

 rather finely, loosely and smoothly punctate, the foveae few in number and 

 minute; the white markings are an oblique humeral lunule, a small iso- 

 lated discal spot on the median line near basal fourth, wholly disconnected 

 from the lunule in both sexes, a slender and abruptly flexed transverse 

 band, the hinder part of which is long, extending almost to apical fourth, 

 a slender apical lunule, abruptly flexed inward anteriorly, and a slender 

 and almost entire marginal line. Length (cf 9) 10.0-13.0 mm.; width 

 3.8-5.0 mm. Nebraska (Lincoln), Harris. 



Mr. Harris informs me that this species was identified by W. 

 Horn as nevadica Lee., and that knausi Leng is a subspecies ac- 

 cording to the catalogue (D. E. Z., 1905), all of which is radically 

 wrong. Even on general principles it might be surmised that a 

 local form occurring nearly a thousand miles from another form 

 and separated therefrom by a vast mountain system, would be 

 different to a marked degree. This surmise is confirmed by the 

 original description of nevadica (Tr. Am. Ent. Soc., 1875, p. 159), 

 which is accompanied by an apparently good figure. From this 

 description it becomes evident that the above lincolniana differs 

 from nevadica in the broadly separated posterior branch of the 

 humeral lunule, very much longer posterior branch of the middle 

 band and in the subentire lateral white margin ; it further differs in 

 the evidently though minutely toothed labrum and in the large 

 sharp outer angle of the elytral apices in the female, this being 

 "obtuse and rounded" in nevadica. In comparing this Nebraskan 

 species with knausi, the error is still more unaccountable, for in the 

 female of knausi the combined elytra form a very large and broadly
