158 GEO. H. HORN, M. D. 



punctured, pubescence brown with a narrow median white stripe. Body beneath 

 sparsely clothed with gray pubescence. Coxal plates finely punctured. Length 

 .06 inch ; 1.5 mm. 



Three specimens, Arizona and Nevada. 



Z. obliteratus n. sp. — General form and sculpture of r.ruciger, but a little 

 more oval. Antennse slender, nearly as long as the entire body. Thorax moder- 

 ately shining, rather densely finely punctured with numerous very coarse punc- 

 tures near the sides, surface sparsely clothed with brownish pubescence. Elytra 

 striate, striae finely punctured, intervals flat finely puuctulate, apices truncate, 

 surface sparsely clothed with brownish pubescence with an indistinct short, median, 

 transverse band of white on each elytron. Pygidium rather coarsely, rugosely 

 punctured, very sparsely clothed with brownish hair, with an indistinct median 

 stripe of white. Body beneath sparsely pubescent, coxal plate coarsely punctured 

 at outer third. Length .08 inch; 2 mm. 



Clcsely allied to cruciger, but more oval, with different vestiture, and 

 the elytra truncate at apex. 



One specimen, Arizona. I have a smaller specimen from Florida 

 which does not seem distinct. 



Z. subiiitens n. sp. — Form rather oval, slightly convex, black, rather shin- 

 ing, sparsely clothed with short, brownish pubescence. Antenuse three-fourths 

 the length of the body. Thorax rather finely punctulate with numerous coarser 

 punctures over the entire surface except for a small region in front of scutellum. 

 Elytra rather wider at base than the thorax, apices subtruncate, rather deeply 

 striate, the strise punctured, intervals slightly convex, finely punctulate with a 

 single row of distant coarser punctures on each, very sparsely pubescent. Py- 

 gidium rather densely finely punctulate with coarser punctures near the sides, 

 very sparsely pubescent. Body beneath shining, very sparsely pubescent. Coxal 

 plate not coarsely punctured externally. Length .08 inch ; 2 mm. 



A little smaller and rather more convex than obliferafus, with more 

 shining surface and less pubescence. There is no trace of elytral band- 



Three specimens, Greorgia. 



Z. densilS n. sp., — Closely related to subnitens and differing as follows: Form 

 more quadrate, surface more shining with very little pubescence. Antennae three- 

 fourths as long as the body. Elytra subtruncate at apex, strife less deep than usual, 

 intervals very flat rather densely punctulate. Pygidium densely punctulate at 

 middle, rugulose and coarsely punctured at the sides. Body beneath sparsely 

 pubescent. Coxal plates not coarsely punctate. Length .06 inch; l.a mm. 

 One specimen, California. 



Z. planirrons n. sp. — Form rather oval, black, moderately shining. Front 

 not or extremely feebly carinate. Antennse half as long as the body, black, the 

 two basal joints usually paler. Thorax rather densely finely punctured, a few 

 coarser punctures at the sides. Elytra separately rounded at tip, striate, strise 

 punctured, intervals very flat, densely punctulate, pubescence gray, sparse and 

 relatively coarse. Pygidium densely punctulate, a few coarser punctures at the 

 sides, very sparsely pubescent. Body beneath sparsely pubescent. Coxal plate? 

 with a very few coarse punctures externally. Length .06 inch : 1.5 mm.
