CICINDELID.E AND CARABID.E 33 



labrum, retracted sides of the thoracic base and fine lineiform dark 

 elytral markings, the posterior of the longitudinal lines but feebly 

 arcuate and not tending at all to approach the suture at its posterior 

 end ; the sculpture of the pronotum also is sensibly different, being 

 a very fine irregular vermiculiform rugulation in the type, though 

 this possibly may not be constant. 



21 A number of undescribed forms in the circumpicta group 

 have been in my cabinet for many years; those most easily identi- 

 fiable are as follows: 



Cicindela circumpicta ssp. ambiens nov. Similar to circumpicta 

 but dark indigo-blue in color, the head and prothorax paler and more 

 lustrous blue, the latter greenish, the under surface very deep blue and 

 partially black; head, labrum and antennae similar; prothorax similar 

 but as long as wide; elytra much shorter and relatively broader, three- 

 fifths longer than wide, similarly sculptured and ornamented but duller 

 in lustre, with the punctures smaller and rather less close-set, becoming 

 very fine and more obsolescent apically than in circumpicta; pubescence 

 of the under surface similar. Length (c?) 12.5 mm.; width 4.9 mm. 

 Kansas. 



The much shorter hind body, coloration and dull surface will 

 enable one to recognize this subspecies very readily. 



Cicindela circumpicta ssp. inspiciens nov. Similar to circumpicta 

 but blackish, with aeneous lustre, more shining; labrum similarly very 

 short but with the median part, bearing the three strong teeth, more 

 advanced; head very shining, with coarser and less numerous plications, 

 which are almost obsolete toward the eyes, the vertex deeply concave, 

 the eyes similarly very prominent; prothorax similar but less rounded 

 at the sides and with the polished surface devoid of any kind of sculpture, 

 except between the sulci and the apical and basal margins; elytra similar 

 in their elongate parallel form and ornamentation, but with the surface 

 more shining and the punctures everywhere sparse, particularly toward 

 base, where they become closer in circumpicta; white pubescence at the 

 sides of the under surface still closer, extremely dense. Length (cf ) 

 13.0 mm.; width 4.65 mm. Texas (Point Isabel). 



Distinct in the very shining surface, blackish-aeneous color and 

 sparse punctures. The female seems to be much less abundant than 

 the male in this part of the circumpicta group; it has the elytral 

 apices rounded as in the togata group. 



In regard to forms of the prcetextata type, Prof. Wickham some 

 years ago obtained a series in southwestern Utah a zoological 

 region also extending for a long distance to the southward the
