Cicindela purpurea of Olivier, or the " purple 

 tiger-beetle," (figure 8,) is often found in company 

 with the foregoing, and is one of the most beauti" 

 fill of our specie^, the play of its glancing colors 

 when in life and motion cannot fail to be admired 

 by the most prejudiced. The head and thorax are 

 coppery, two streaks between the eyes, and the 

 Fig. 8. two impressed lines of the thorax green ; elytra 

 generally of a bright copper color, sometimes, however, clouded 

 with green, a whitish, irregular, abbreviated band behind the 

 middle, and the terminal lunule usually broken so that a small, 

 round dot, and the tip alone remain ; feet reddish coppery, and 

 with the green body beneath somewhat hairy. Length a little 

 more than .50 ; breadth al)out .23. 



Cicindela Itirticdl/is of Say, or " hairy necked 

 tiger-beetle " (figure 9.) has but one black tooth on 

 the white labrnm, but to the superficial observer 

 would appear like a small specimen of the g-enerosa, 

 the colors of the head and thorax are brighter than 

 in that species, and thorax as the name implies is 

 thickly clothed with whitish hairs on the sides ; 

 the white mai-gin is not continuous, the external 

 points of the middle lunule being separated from those of the 

 others by the ground color of the elytra ; it is also much 

 smaller, measuring from .43 to .50 in length and about .22 in 

 breadth. 



Cicindela hemorrhoidalis of Hentz, or " red-tailed tiger- 

 beetle" is found only in the vicinity of the Blue Hills in Milton 

 and the neighboring towns, and is readily distinguishable from 

 our other Massachusetts species by its red abdomen, which 

 when flying " appears like a drop of blood suspended to its 

 tail," (Dr. A. A. Gould.) ]t measures about .45 in length and 

 from .18 to .20 in breadth. 



Cicindela sexgutldta of Fabricius, or " six-spotted 

 tiger-beetle," (figure 10,) is of a bright green, occa- 

 sionally changing to blue after death ; it is marked 

 on each clijtron with a small white spot about the 

 middle of the margin, a smaller one behind this, 

 and the tip white. This species measures from .45 

 to .50 in length, and rather less than .22 in breadth. 

 I have found it more conunon in lonely paths
