CICINDELA OREGONA LeConte. 



Figs. 67, 104, and 134. 



Shelford, not reared, larvae in the collection of the University of Illinois, 

 U. S. National Museum, and the author's collection. 



Color. — Head and pronotum dark coppery bronze with a strong 

 blue reflection, lateral margins of pronotum lighter in some speci- 

 mens ; setae on dorsal aspect of head and pronotum white, the other 

 setae brown. 



Head. — Setae on dorsal aspect slender, of medium length and not 

 conspicuous; diameter of ocellus 2 equal to the distance between 

 ocelli 1 and 2; fronto-clypeo-labral area slightly wider than long: 

 U-shaped ridge on caudal part of frons bearing two setae; antenna 

 with the proximal segment slightly shorter than the second, the third 

 two-thirds and the distal one-half the length of the second, the proxi- 

 mal segment with nine to eleven setae and the second with nine to 

 eleven setae ; maxilla with the proximal segment of the galea bearing 

 three setae on its mesal margin, maxillary palpus three-segmented; 

 ligula with four fine setae arranged in a transverse row at its ventro- 

 distal end, proximal segment of labial palpus with three spinelike 

 projections on the ventro-distal margin and with two setae on each 

 side of these spines, the proximal segment with four setae and the 

 distal segment with one. 



Thorajx. — Pronotum with the cephalo-lateral angles extending al- 

 most as far cephalad as the mesal portion, lateral margins carinate, 

 primary setae not large or prominent, secondary setae short, about 

 25 to 30 in number and with a row on each side of the meson (fig.67) . 



Abdomen. — Chitinized areas distinct, secondary setae about one- 

 fourth the length of the primary setae, fine and not numerous (fig. 

 104) ; ninth abdominal sternum with the caudal margin bearing two 

 groups of three setae each; median hooks with three setae; inner 

 hooks with two setae, the spinelike projection about one-third the 

 length of the hook (fig. 134). 



Mecmirements. — Length of larvae, 19 to 22 mm., width at the 

 third abdominal segment, 2.3 to 2.5 mm. ; diameter of ocellus 2, 0.26 to 

 0.28 mm. ; distance between ocelli 1 and 2, 0.26 to 0.28 mm. : length 

 of fronto-clypeo-labral area, 1.60 to 1.70 mm., width, 1.70 to 1.80 

 mm. ; length of pronotum, 1.80 to 2 mm., width, 3 to 3.3 mm. 



The larvae of this species are similar to Cicindcla 12 -guttata., but 

 can be distinguished from them by the larger number of setae on the 

 pronotum and the blue reflection, which is much stronger. The 

 larvae were collected at Albuquerque, New Mexico, and Hagerman, 

 Idaho, in moist clay soil with some humus, at an elevation of 6,000 to
