REVISION OF ELEODIINT BLAISDELL. 229 



Doctor Horn in the Revision failed to mention that the female was 

 caudate. 



Forma glabra is a rather striking variation, on account of the 

 smooth integuments and in having the cauda longer than usual in the 

 male, and moderately arcuately decurved in its apical third, being 

 gradually narrowed from base to apex. 



Forma sublaevis has the sculpturing of sponsa, and forma scabra 

 has the elytra tuberculo-scabrous. The mentum is comparatively 

 rather small and triangulo-trapezoidal in outline. The sides con- 

 verge anteriorly and are scarcely at all arcuate; the apex is more or 

 less rounded and the surface is more or less foveate as well as coarsely 

 punctured. 



The mentum and sides of the epistoma are set with rather long 

 black hairs. 



The presternum is variable, moderately wide between the coxa) 

 and somewhat triangularly dilated behind the equator of the coxae; 

 more or less convex antero-posteriorly, or feebly convex to subhori- 

 zontal between the acetabula; more or less moderately produced and 

 compressed, oblique to vertically truncate behind, at times sub- 

 mucronate. 



The mesosternum is variable as to the degree of obliquity and 

 more or less concave. 



The abdominal process is subquadrate, slightly wider than long 

 and about as wide as the j)ost-coxal portion is long, the latter 

 equal in length to the second segment; the third is twice as long as 

 the fourth, and about one-third of its length shorter than the second. 



The abdominal salient is about one-seventh of its width wider than 

 the metasternal process. 



The metasternum laterally between the coxse is about as long as 

 a mesofemur is wide at base. 



The tibial grooves of the femora are not entire, the floors are 

 glabrous, quite plane, and limited by rather well defined edges. 

 Those of the profemora are moderate in width; the anterior margin 

 is scarcely dentately laminate at the outer third in the male and less 

 so in the female; the posterior margin is obsolete internally before 

 becoming contiguous with the anterior, neither one reaching the 

 femoral base. 



The mesofemoral grooves are obsolete at'the internal third of the 

 femora and the margins do not become contiguous; on the meta- 

 femora they scarcely extend basally beyond the middle, where the}?^ 

 become evanescent before becoming contiguous. 



The protibiiB are somewhat compressed and distinctly carinate 

 ■ externally ; the tarsal grooves are scarcely developed and muricate.
