EXPLANATION OF PLATES VI, VII, AND VIII. 



Fii^s. 1, 2, males, 3, 4, females, Cclitlicnits fasciata Kirby, all from 

 Slidell,"^ Louisiana, July 2, 1905, J. S. Mine. 



Figs. 5, 6, males, 7, S, 9, females, Celithemis monomelaena 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 monomelaena 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 Figtires 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 , coinpletely 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 figures 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 190S. It is in a railroad cut east of Barnesville. The 

 plants are increasing rapidly from seeds. The}^ grow well when 

 transplanted. 



2. Viola blanda Willd. This violet was also first found in 

 190S 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 localitv.
