in North America alone. The original description probably refers to 

 either the Madagascan, New Holland or Tasnianian representatives. 

 Our four species may be easily separated as follows: — 



Castaneous ; elytra each with two large oblique spots of pale flavate. 



piilcliellus 

 Piceous-black ; elytral snture, lateral and apical margins, and a transverse 



band at basal third paler, rufo-testaceous criicigerus 



Piceous above throughout, the suture sometimes very narrowly, indefinitely 



and feebly rufescent imiuaculatllS 



Intense black throughout above aterrililUS 



r,. pillctaellus Lee— Proc. Ac. Phil., 18.56, p. 17.— Evenly and not very 

 broadly oval, moderately convex, dark brownish-testaceous, tlie elytra each 

 with two oblique pale- flavate spots, one near the base and the other near the 

 apex, the latter the larger, neither attaining the suture or the lateral margin, 

 the anterior extending from near the humeri to anterior third, and slightly 

 sinuous ; under surface throughout pale flavate. Head polished, extremely 

 minutely and rather sparsely punctate ; eyes large ; antfennse slender, outer 

 joints of funicle slightly more robust and slightly transverse, third not as long 

 as the next two combined, club slender, as long as the seven preceding joints, 

 eleventh distinctly longer than the two preceding together. Protliorax short, 

 much more than twice as wide as long, polished, not reticulate, very finely, 

 moderately sparsely punctate ; basal lobe wide, abrupt, short but very distinct, 

 the apex transverse ; marginal bead obsolete. Scutellum angulate, slightly 

 wider than long ; sides feebly arcuate. Elytra very minutely but distinctly 

 strigilate in transverse wavy lines throughout, having series of very wide 

 feeble and feebly crescentiform punctures, which become wider near the sides 

 where the series are still regular ; intervals near the sides with single regular 

 series of very small punctures of similar nature, which, toward the suture, 

 become much more minute and feeble, and confusedly dispersed over the 

 entire interval, especially between the discal strije ; the latter fine but dis- 

 tinct, obsolete at basal third or fourth, the first continuous to the apex, the 

 second coincident with the first at apical fifth ; sutural bead obsolete, except 

 toward apex, where it is excessively fine, feeble and just traceable. Legs very 

 slender ; posterior tibial spurs slender, long and distinct, slightly unequal, 

 the tarsi extremely slender, cylindrical, the first joint fully one-third longer 

 than the entire remainder. Length 1.1-1.7 mm. 



Florida ; Texas. 



The metasternal process is wide, and extends to the anterior 

 limits of the coxae, the mesosternum before it l)eing very short and 

 transverse, and not at all prominent; the prosternal process is rather 

 wide and feebly dilated at the inflexed apex. 



L<. criicigerus n. sp. — Narrowly, almost evenly elliptical, strongly 

 convex, polished, piceous-black, the suture and lateral and apical margins
