the radical nature of its peculiarities of structure, with either Olibrus 

 or Stilbus; it is essentially tropical, but extends into the southern 

 limits of the United States, where it is represented by two species 

 characterized as follows : — 



Pale testaceous ; elytra black, with the margins and two oval approximate 



sjjots just before the middle pale priiiceps 



Pale ochreous-flavate throughoixt Ullifoi'inis 



Li. princeps Schwarz. — Proc. Am. Phil. Soc, XVII, p. 361. — Rather 

 broadly, evenly elliptical, moderately convex, polished ; head, pronotum, a 

 large oblique oval spot on each elytron before the middle, attaining the suture, 

 the lateral margin and apex narrowly, entire under surface, legs and antennae 

 pale rufo-testaceous ; remainder of the elytra black. Head polished, some- 

 what coarsely, sparsely and feebly punctate ; eyes large, their inner margin 

 slightly elevated above the general surface of the vertex ; epistoma without a 

 beaded margin, except laterally along the antennal sinuations ; antennae rather 

 long and robust, joints three to five decreasing uniformly and very slightly in 

 length, outer joints of funicle slightly more robust, seventh and eighth equal 

 in length, the latter just visibly wider than long, club rather robust, strongly 

 asymmetric, the anterior sides much more strongly angulate, and the eleventh 

 joint slightly lobed on this side near the base, longer than the two preceding 

 together. Prothorax much more than twice as wide as long, not reticulate, 

 very minutely and obsoletely, but somewhat densely punctate ; basal lobe 

 moderate, broadly, evenly arcuate, the basal bead fine, very strong, extending 

 laterally to within one-fourth the width of the sides, with its posterior margin 

 finely and very strongly granulose. Scutellum equilatero-triangular, small, 

 the sides very feebly arcuate. Elytra polished, the transverse strigilation so 

 minute as to be merely suggested by a very feeble opalescence under high 

 power, having rows of very small, rounded punctures which are larger, deeper 

 and more distinct at the sides, always cresceutiform, the intervals with an 

 obscurely double line of nearly similar punctures ; discal stria obsolete at 

 basal third. Abdomen coarsely, sparsely pubescent. Legs short and very 

 stout, the posterior tibiae short, obliquely truncate at apex, the truncation 

 sinuate; spurs very long, stout, and distinctly unequal, the corresponding 

 tarsi nearly as long as the tibiae, the first joint short above, very strongly pro- 

 duced beneath the second; second joint arcuate above near the base, more 

 than four times as long as the upper or shorter side of the basal joint, and 

 very much longer than the entire remainder. Length 2.6 mm. 



Florida. Mr. Schwarz. 



The metasternal process is narrow and ver)'- short, flat, impunc- 

 tate, truncate at apex, the niesosternum in front of it abruptly 

 declivous, and extending laterally so as to slightly envelop the 

 middle coxae, having one or two robust setae at the sides near the 

 coxae and metasternum, not at all prominent; prosternal process 

 moderate, with two or three very fine feebly developed setse.
