cool days, this species will congregate under cow chips and other places 

 of shelter. The colours vary, more commonly bronze, frequently green, 

 and less frequently blue ; the elytral markings are also variable. 



C. togata, Laf., occurs with the above species in all localities except 

 on the salt marshes in Kansas, near Fredonia. It continues a little later 

 in the season than circumpicta and is more difficult to capture, and it is 

 also more commonly found on the bare open saline soil. Both the above 

 species have long legs, are swift runners and quick fliers ; the flight of 

 circumpicta being more sustained than that of togata. The togatas taken 

 near Kackley, in Republic County, have recently been described by Dr. 

 W. Horn, of Berlin, Germany, under the varietal name oi Apica/is. 



The following is a translation of Dr. Walther Horn's description : 



" Cicindela togata, Laf, var. apica/is, differs from the type by 

 its greater size, more robust form, eyes less prominent, head and thorax 

 very often much thicker ; each apex of the elytra in the female much less 

 rounded (the sutural spine a little retracted), in the male more acuminate ; 

 sculpture denser, the punctures sometimes here and there confluent ; the 

 markings brownish yellow and narrower. Length, 1 1)^-121^ mm." 



" This form (var. apica/is) of C. togata is specially remarkable from 

 the striking shape of the apex of the wing-cases. The row of fossulse 

 along the suture is much less prominent. The sculpturing of the 

 wing-cases is distinctly more dense, the punctures are sometimes to a 

 considerable degree confluent (they remain always more distant from 

 each other at the very base and at the apex). The differences in the 

 width of the prothorax are specially great in the ^ specimen." 



"Though the specimens before me show no variation at all consider- 

 able in the shape of the apex of the wing-cases, I have, nevertheless, 

 decided to describe them only as a race of C togata, as this character 

 is very little constant in the whole genus Cicinde/a. Twenty years ago 

 my illustrious colleague. Dr. (reorge Horn, tried to separate as species 

 the three forms, cuprascens, macra, piiritana, using much slighter 

 variations of the same character. I cannot, however, agree in this 

 view. The differences stated are most variable, as well as the sculp- 

 turing of the wing-cases, the pattern, etc. The lateral emargination 

 before the apex of the 2 of C. piiritana is sometimes less sliarp than in 

 C. macra, and the latter has often its apex ( 9 ) quite as much truncated. 

 Besides, C. cuprascens is far less constant. Especially in the ^ , 

 transitions are frequent. I can therefore hold C. puritana, Horn,
