fulvous, closely and concolorously punctate except at base and apex 

 of each segment where the surface is smudged with fuscous encircling 

 the smooth pale callosed edges of the incisures ; lateral margin of con- 

 nexivum either side of incisures black. All beneath and legs entirely 

 clear pale stramineous, with lateral edges of abdomen either side of 

 incisures of segments 2-5, tip of 6th and edges of genital segment of 

 9, black. Spiracles concolorous. In the female the side pieces or 

 lateral lobes of the genital segment are placed in a line with the long 

 axis of the body and elongate, while in fruticicola these pieces are set 

 more obliquely and not so much drawn out to an acuminate apex. 

 Length of $ 7.5 mm., $ 8.5 mm. 



Described from one male and two females collected by me

On Some Rare Cicindelae (Coleop.). 



BY R. P. Dow, New York City. 



Among the material received last year from Mr. John Wood- 

 gate, Ft. Wingate, New Mexico, were long series of a Cicindcla 

 labelled by him mlturina. All were taken in July and August, 

 and were about equally divided between black and green forms. 

 The former agree perfectly with the description of santo- 

 clarae Bates. The earlier insects are generally green. A 

 month later the black predominates. Both forms are the same 

 insect, beyond a doubt, but examination of elytra under a 

 strong lens with transmitted light shows that the amount of 

 pigment in the black form is easily twice that of the green, 

 and the color of the former mainly due to broken light rays, 

 rather than pigment. The black color is piceous. In over 300 

 specimens there are no intermediates. I therefore suggest the 

 varietal name anita for the black form. It is not ill known 

 already to collectors. 



In the same material I found two specimens which are be- 

 yond a doubt sperata. I have a good share of the color forms 

 recognized in the E. D. Harris catalogue. The amount of 

 pigment in all these forms is about equal and the color due al- 

 most entirely to broken light rays. My two specimens are 

 light emerald green. All others of the species that I have seen
