EXPLANATION OF PLATES VI, VII, AND VIII. 
Figs. 1, 2, males, 3, 4, females, Celith.em.is fasciata Kirby, all from 
Slidell, Louisiana, July 2, 1905, J. S. Hine. 
Figs. 5, 0, males, 7, 8, 9, females, Celithemis monomclacna new species, 
all from Whitley County, Indiana, excepting 6 from Kent, Ohio, J. S. 
Hine. 7 is the type 9 of monomelaena . 5, 8 and 9 are teneral specimens. 
Wings of monomclacna have been selected to show the extremes of 
variation in wing markings. Notice wing apices in 7, 8 and 9, and notice 
hind wings in these 3 figures showing that a great development of one 
colored area is not necessarily associated with other greatly developed 
areas in the same wing. In Figures 1 and 2 the enclosed pale basal area in 
the hind wing is open to the wing border proximally as in Figures 3 and 4, 
but the orange color of the pale area is so intense as to obscure this in the 
photographs. Notice that in fasciata this pale area is always open to the 
border proximally, and is closed or tends to close across the posterior end 
of the anal loop (nearly closed in Figure 1 , completely closed in 2, 3 and 4) ; 
monomelaena, on the other hand, tends to close proximally (see Fig. 6) 
and remains open posteriorly across the anal loop. There is in the 
behavior of these colored parts two distinct tendencies in the two species 
(compare these areas in kigures 4 and 6). 
TWENTY-FIVE RARE PLANTS AT BARNESVILLE, OHIO. 
Emma E. Laughlin. 
Every locality has its plants which are found in great pro- 
fusion, and also those which are rare, although they may be the 
common plants in another region. To the botanist it is always 
a special pleasure to find the retreat of some rare local species. 
Below are noted twenty-five plants which may be regarded as 
locally rare within a circle having a radius of four miles with 
Barnesville, Belmont County, as a center. A more careful study 
of the region might show some of the species more common than 
they are now supposed to be. 
1 . Viola rafinesquii Greene. One station was found for this 
violet in 1908. It is in a railroad cut east of Barnesville. The 
plants are increasing rapidly from seeds. They grow well when 
transplanted. 
2. Viola blanda Willd. This violet was also first found in 
1908 in a deep shady ravine through which a small stream creeps. 
It is most abundant at the end of the ravine where a tiny swampy 
flood plain has been formed. 
3. Viola hastata Michx. One station discovered in 1907 in 
a dense wood. Its location has been revealed to only three 
people so that the plants may be allowed to increase. It is 
probable that other stations may be found as this violet is not 
rare in the adjoining county. Ten other violets may be regarded 
as common in this locality.
