24 MEMOIRS ON THE COLEOPTERA 



Cicindela decemnotata ssp. albertina nov. Larger and still more 

 elongate than decemnotata, green, with feeble subcupreous reflections 

 and rather shining, the under surface paler green; lateral margins broadly 

 shining and brighter green; elytral maculation as in decemnotata, though 

 relatively not quite so broad and with the apical lunule, which is broad 

 and entire as a rule in that species, strongly divided, the outer part form- 

 ing a rounded discal spot; middle band with the oblique posterior part 

 similarly long, but with the outer part tending less to attain the lateral 

 edges, the outer metallic border being more developed; all the pale spots 

 and bands seem more widely isolated among themselves, owing to the 

 larger size of the body and relatively narrower maculation. Length 

 (cf 9 ) 11.8-13.0 mm.; width 4.75-5.0 mm. Canada (Lethbridge, 

 Alberta). Communicated by Mr. Criddle. 



I have seen only the type pair, which has been compared with 

 three very good examples of the typical decemnotata. 



12 In the for "mo s a group there are three subgroups, represented 

 by formosa, of very stout build and moderately elongate, very 

 strongly tridentate labrum, venusta, having a much narrower body 

 but still longer though not quite so strongly tridentate labrum, 

 and admiscens, having a short transverse labrum as in the trangue- 

 barica group, with a narrow body and markings as in vemista. The 

 following is a very brilliant modification of formosa: 



Cicindela formosa ssp. luxuriosa nov. Form nearly as in formosa 

 but not quite so stout, with strong opaque-sericeous lustre, bright coppery 

 to purplish-red throughout above, the white elytral margins much nar- 

 rower than in formosa, with the middle band much narrower, more 

 transverse and less elbowed; legs and under surface bright blue; pu- 

 bescence and sculpture throughout nearly similar. Length (cf) 15.0 

 mm.; width 5.7-5.9 mm. Colorado (near Denver), Soltau. 



Though evidently a modification of formosa, this very beautiful 

 form merits special designation because of the very great recession 

 of the characteristically broad markings of the formosa section. 



Cicindela venusta ssp. versuta nov. Nearly similar to venusta but 

 larger and evidently somewhat stouter, the coloration more reddish and 

 less opaque coppery, the pale markings even a little broader; under surface 

 bright green, the sides of the prothorax and the sternal side-pieces bright 

 cupreous; long white pubescence much more abundant, especially on the 

 femora. Length (c? 9 ) 11.8-14.0 mm.; width 4.6-5.5 mm. Canada 

 (Aweme, Manitoba), Criddle. 



In venusta the color is pale green throughout beneath; my series 

 is from Kansas and Colorado.
