i8 MEMOIRS ON THE COLEOPTERA 



(cf) or pale becoming gradually black at the periphery (9 ); elytra with 

 the punctures not generally isolated as they are in montana but confluent, 

 each elytron having merely a slender elbowed discal middle band pale; 

 legs and tarsi similarly rather slender. Length (d 7| 9) 1 1.0-13.0 mm.; 

 width 4.7-5.0 mm. Canada (Calgary, Alberta). 



The following is certainly a distinct species of the montana 

 subgroup : 



Cicindela spissitarsis n. sp. Short, feebly convex, black, the bottoms 

 of the elytral punctures obscure green; under surface purplish-black, 

 the abdomen metallic green and violet; labrum (9) as in longilabris, 

 black throughout; head and prothorax with dense rugulation, which is 

 longitudinal but not very regular on the front, the latter nearly flat, 

 abruptly depressed at the inner margins of the eyes ; prothorax transverse, 

 deeply, transversely bisulcate; elytra rather less than one-half longer 

 than wide, sculptured nearly as in canadensis, the punctures very dense 

 and confusedly confluent, each elytron with only the inner end of the 

 middle band pale; legs rather short, the tarsi stouter than in any other 

 American species of the genus, the posterior equal in length to the tibiae, 

 pale piceo-testaceous in color, the third joint distinctly less than three 

 times as long as wide. Length (9) n.o mm.; width 4.7 mm. Canada 

 (Aweme, Manitoba), Norman Criddle. 



The tarsal structure, sculpture and coloration in this species 

 isolate it at once among its fellows. The following belongs to the 

 perviridis section of the present group: 



Cicindela perviridis ssp. placerensis nov. Oblong, rather depressed) 

 dull in lustre, the upper surface blue to obscure green, the entire under 

 surface polished and pure blue to greenish-blue; labrum as in perviridis, 

 similar in the sexes, pale throughout, the apex rather narrowly truncate, 

 with a strong tooth projecting from the truncature; vertex concave, 

 distinctly and subevenly strigilate; prothorax very short and strongly 

 transverse, the sides converging and nearly straight from apex to base, 

 the transverse sulci deeper blue; elytra as in perviridis in maculation and 

 sculpture but shorter and more obtuse at apex, the punctures very shallow, 

 granulose as usual, confluent and each with a shining elevation; some- 

 times the surface seems to be almost even, with only the shining eleva- 

 tions remaining; legs rather long, slender, the hind tarsi longer than the 

 tibice. Length (c? 9 ) 12.0-12.8 mm.; width 4.7-5.3 mm. California 

 (Placer Co.), Koebele. 



In my only male example of perviridis the outline is more elon- 

 gate, the surface similarly very feebly convex, the color pure green 

 but with dull lustre above and pure metallic green throughout 

 beneath; the prothorax is distinctly less transverse, with the 

 sulci not or scarcely at all deeper in color; the humeral lunule is 

 complete, the middle band expanded at the margin, extending
