margin ; apical process large, bent rectangularly, proximal edge obliquely 
sinuate towards the tip. 
Tampa. Ihave described this species from fragments found 
by Mr. Schwarz. It is much larger than the other species in 
our fauna, as the elytra of the largest specimen of semi- 
opacus in my collection are 12.5 mm.; .475 inch long. 
This species seems to have a rather wide distribution in 
the Atlantic States. Dr. C. Zimmermann once told me that 
he had found a large blue Geotrupes, without impressed 
striee, 1n South Carolina, and if I mistake not I have seen a 
similar specimen from Maryland, in Mr. Ulke’s collection. 
70. Diplotaxis languida, n. sp.—Elongate, sub-cylindrical, pale- 
brown ; head strongly punctured, epistoma depressed, margin strongly re- 
flexed, broadly truncate in front, angles obtuse and rounded.  Prothorax 
about twice as wide as its length, more narrowed in front, less narrowed 
behind, sides with an obtuse, rounded angle just behind the middle ; dise 
strongly punctured. Elytra with the ordinary rows of punctures, inter- 
spaces coarsely and strongly punctured. Front tibie with two large teeth ; 
claws cleft. Length 6.2 mm.; ,95 inch. 
Tampa ; abundant. 
71. Anomala (Rhombonyx) semilivida, n. sp.—Oval, piceous, 
shining, more or less whitish testaceous above, elytra usually entirely pale. 
Head sparsely punctulate, epistoma pale, concave, rounded in front, mar- 
gin strongly reflexed. Prothorax twice as wide as long, much narrower 
in front. Sides rounded, very finely margined, base similarly margined ; 
disc sparsely punctulate, with a large transverse dark cloud, sometimes 
occupying nearly the whole surface. Scutellum large, rounded behind, 
dark colored. Elytra with the usual punctured equidistant strie. First 
interspace wider, with a confused row of punctures from the base to the 
middle ; outer strie somewhat effaced. Legs usually margined with pale ; 
claws simple. Body beneath, thighs and margin of elytra with long hairs. 
Length 6.5 mm.; .25 inch. 
Tampa and Capron. The inner claw of the front tarsi is 
toothed near the base and then suddenly bent, with the lower 
outline slightly sinuate to the tip in four specimens exam- 
ined; this is probably a sexual mark of the ری‎ though one 
of the speeimens is much stouter in form than the others. 
72. Taphrocerus levicollis, n. sp. —Very small, slender, convex, 
narrower behind, black-bronzed, shining. Head and prothorax nearly 
smooth, the former large, longitudinally impressed ; the latter with very 
deep oblique impressions towards the sides, which are nearly straight and
