DYNASTIN/E 183 



fourth anterior tibial tooth small and obtuse but obvious in both 

 sexes, the larger claw of the male as in the preceding species, the 

 apical stylet generally longer, more abruptly formed and conspicuous. 

 Length (cf 9 ) 16.0-22.0 mm.; width 8.7-12.2 mm. Rhode Island 

 to Iowa. Common. Thirty-six examples. [Scarabaus relictus Sa>]. 



relictus Say 



A Form nearly as in relictus but more elongate; head larger, the eyes 

 distinctly larger and more prominent, separated by less than three 

 times their width, while in the female of relictus the eyes are 

 separated by more than three and one-half times their width; 

 prothorax somewhat similar in form but less narrowed apically 

 and differing in the very minute punctures, remotely scattered 

 over the more highly polished surface; elytra slightly more elongate 

 but otherwise nearly similar throughout; pygidium nearly similar 

 but with the rugulosity deeper and more punctiform; hind tibiae 

 rather less broad. Length (9) 22.7 mm.; width ir.6 mm. 



Iowa (Keokuk). A single example vernicicollis n. subsp. 



Form narrower, more elongate, subcylindric-oval, convex, polished, 

 piceous-black, the under surface and legs rather bright brownish- 

 rufous; head similar but not quite so large and with the diffuse 

 wavy rugulosity feebler, the basal regions similarly smooth; segments 

 of the interrupted ridge decidedly tuberculiform internally, gradu- 

 ally diminishing externally and not quite attaining the sides; punc- 

 tures of their anterior slopes excessively minute and sparse; concave 

 clypeus trapezoidal, with the sides unusually sinuate, the apical 

 teeth acute but small and only moderately upturned, rather less 

 approximate than in relictus but much closer than in sallei; prothorax 

 three-fifths wider than long, the sides moderately converging and 

 distinctly arcuate from the broadly rounded basal angles to the apex; 

 punctures as in relictus; scutellum not so large or broad, smooth, 

 with fine punctulation only at base; elytra nearly a fourth longer 

 than wide, not distinctly (c?) or nearly a fourth (9 ) wider than the 

 prothorax, slightly inflated apically in the female, broadly rounded 

 at apex; punctures not close, arranged as in the preceding species, 

 each of the rather large impressed punctures inclosing an annulus; 

 geminate series much less definite than in relictus; pygidium differing 

 greatly in sculpture, polished, sparsely and strongly punctured 

 throughout, the apical region in both sexes, but especially the female, 

 becoming more finely and very remotely punctulate; fourth tibial 

 tooth very small, feeble and indistinct; larger claw of the male with 

 the apex arcuato-truncate, the minute stylet projecting from its 

 lower limit and in prolongation of the lower margin. Length (cf 9 ) 

 17.0 mm.; width 9.2-9.75 mm. Mexico (San Angel, near the city), 



Wickham : *propinquus n. sp. 



8 Form, lustre and coloration throughout as in the preceding but of 

 larger size; head nearly similar but with the median transversely 

 oval concavity of the front deeper and more distinct and with the 

 clypeal teeth separated by two-thirds the distance separating the 

 crests of the frontal elevations, whereas in propinquus this proportion 

 is barely more than one-half; prothorax similar but rather less ab-
