In this, as in other IJiifones, the females are larger than the males; 

 and the latter are usually less variegated in colors. 



The li. /. <('Heric(iiiush,\'i been regarded by some authors as a species 

 distinct from the li.UciititfinosHs; but the examiiiationof a largenuinber 

 of specimens of both shows that all of the distinctive characters arc 

 evanescent in some individuals. Thus the supeixiiliary crests rise pos- 

 teriorly in No. 2197 from Minnesota, so as to ai)proximate the typical 

 lientiginosiis. In some of the spe(!iinens of No. 1*521, from Charleston, 

 8. C, the extremities of tlie crests are not more developed than in No. 

 2534, from the IMatte liiver, Nebraska. The sui>ratyinpanic crest is 

 represented by an angle of the i)ostorbital in the great majority of spec- 

 iiiKMis, but in seventeen specimens tiie fanner is quite as distiiuit as in 

 nnmenuis specimens of the />. L lenfifjimtnifi. These belong to Nos. 2181, 

 2193, 2172, 2174, 2197, 2557, 5372, and 19900. Nevertheless, it is true 

 that the subspecies B! I. amcricdniis maintains its characters entirely 

 within the range of the />. /. lentiniiiosiis, as is evidenced by specimens 

 from Prairie Mer Rouge, La. (2557), Milledgevilie, C.a. (9139), Monti- 

 cello, Miss., and elsewhere. 



As already deserilu'd, the par.>toid ghiiids of this species are long and 

 rather narrow. A vaiietal form has them wider and renifonn in out- 

 line. The live individuals which display this character are from north-
