June, shows quite a good deal of variation in the markings, the 

 changes chiefly affecting the middle band. The marginal por- 

 tion of this band is variously developed so that it may reach 

 quite to the humeral lunule and almost to the apical one, or it 

 may not be expanded at all. The discal part may be quite rec- 

 tangularly or very obliquely bent near the middle and the termi- 

 nal knob-like appendix may be abruptly formed and angularly 

 bent from the stem or it may appear simply as an enlargement, 

 without being noticeably deflected at all. A set from Humboldt 

 Lake, Nevada, taken by myself in June, while not identical with 

 the Saltair forms, shows a range of variations almost exactly 

 corresponding thereto, all of the important features of the one 

 being duplicated in the other. 



On the shores of Honey Lake, near Amedee, California, I 

 took a fine series of Cicindela which I refer, for convenience, to 

 C. echo, though they are not typical. The form is nearly the 

 same and the ground colors are about alike, but the Amedee 

 specimens almost entirely lack metallic gloss and the surface 

 sculpture of the elytra is notably shallower. The Amedee 

 beetles also differ, as a species, from the Saltair specimens in 

 the broader markings, the greater obliquity of the median band 

 (the terminal knob less deflected), and in the expansion of this 

 band along the margin so as to connect broadly with the humeral 

 lunule. The apical lunule is free in all of my specimens. 

 One mdividual is entirely blackish, except that each elytron 

 bears two small spots, one of which represents the anterior por- 

 tion of the humeral lunule, the other the posterior part of the 

 ajDical. ^

 close to those of the Saltair echo; the middle band does not 

 Show a distmct tendency to spread along the margin in any of 

 my specmiens, so that it is not connected with nor closely 

 approximated by the apical and humeral lunules. The chief 

 varia ions are those exhibited in the descending portion of the 

 midd e band, for though this band is usually rectangularly bent 

 the terminal knob shows numerous modifications In some
