tures coarse, deep, quadrate, and seriate, becoming finer posteriorly 

 and obsolete at apex; interstices rugose; black, the sutural and 

 lateral margins pale yellow. Pro- and mesosternum yellow, the 

 former rarely piceous; abdomen varying from entirely piceous to 

 piceous with two apical segments and posterior margin of remaining 

 segments yellowish. Legs pale yellowish, the knees and anterior 

 tibiae and tarsi often piceous. Length 4-6.5 millim. 



This is a widely distributed and well known species and one 

 which cannot easily be confused with any other. The elytral markings 

 are rather constant; practically the only variation is the frequent 

 failure of the pale border of the lateral margins to reach the base of 

 the elytra, in some instances attaining a point but little beyond the 

 middle; the thoracic markings are, on the contrary, quite variable. 

 An example from Massachusetts, has the pronotum entirely piceous 

 except at middle of apex and of base, where there is a small triangular 

 yellow maculation, the base of which is at the margins; thus forms 

 may be expected to occur with the pronotum entirely piceous. 



Pelonium lineolatum Gorh., described from Guatemala, to judge 

 by the description, agrees perfectly with this species, in form, struc- 

 ture of the antennae, sculpture, and size; it differs only very slightly 

 in color, the head being somewhat paler. The author, however, has 

 seen no specimens of oculata from Mexico or Central America and 

 hence must leave the identity of the species in doubt, with the hope 

 that those to whom the type of Gorham's species is accessible will 

 ere long make known the differential characters, if such exist.

The writer wishes to call attention here to an error which has 

 apparently escaped correction. Oculata was placed by Dr. LeConte 

 (Ann. Lye. Nat. Hist. N. Y., v, 1849, p. 32) in a group characterized 

 as possessing' eleven-jointed antennae; and again later on (Smiths. 

 Misc. Coll., vi, 1865, p. 98) the same author states that the antennae are 

 eleven -jointed, vetusta, fasciata, oculata, and mixta being specifically 

 mentioned; a careful examination of the antennae of the various 

 species reveals the fact that this is true of leucophcea (vetusta), fas- 

 ciata, and maculicollis , but certainly not of oculata, mixta, and quad- 

 risignata, the antennas of which are but ten-jointed.
