and a humeral, basal and \'er\- large postmedian triangular spot on 

 each elytron \ello\v; antenna\ palpi and legs yellow, the femora 

 slightly clouded with fuscous. Elytra feebly and broadh' ciir\ed 

 from behind the humeri to apex. Length 2.5 mm. 



Ocala, F'lorida; April 17. Allied to />. quadripiinctala Melsli., 

 but form distincth' narrower and more elongate-oval, punctures 

 much sparser and colour of ehtra and legs very different from that 

 species or an\- of its varieties. The large yellow spot on each 

 elytron is triangular, with its broad emarginate base extending 

 from the margin near middle four-fifths the distance to suture, 

 its sides graduall\' con\erging backwards to an obtusely rounded 

 apex near the tip (jf each elytron. The elytra, in fact, are as much 

 \ellow as black, the black areas comprising a rather broad suiural 

 stripe, a broad cross-bar on basal third, with a mediimi spin' for- 

 ward between ilie \(.llo\\ basal and humeral spots, and a narrow 

 apical bar. The larger yellow spot is narrowly connected along the 

 margin and epipleura with the one on humerus. 



Family ScaraB/EID^. 

 Onthophagus nigrescens, sp uon . 



Broadly oval. Above uniform black, strongly shining; beneath 

 reddish brown, antenna? and palpi paler. Clypcus with margin 

 strongly refle.xed, elevated and feebly emarginate at middle, surface 

 of clypeus very sparsely and finely punctate. Vertical carina ol)SO- 

 lete at middle, elevated at each end into a long tapering horn Which 

 extends abo\e the level of the thorax. Thorax with front median 

 portion of disc strongly convex and rounded but without a sign of a 

 process; surface finely and rather sparsely punctate, each puncture 

 bearing a very short erect blackish seta. Klytral stride fine; interxals 

 feebly con\ex, not alutaceous, each with two or three rows of 

 minute punctures, their seta.^ extremely short, almcst inxisible. 

 Pygidium coarsely and rather closely punctate. I'ndcr surface 

 finely and very sparsely punctate, the abdomen minutely alutace- 

 ous. Length 6 mm.
