mens a Zeiss binocular with objective a 3 and eyepiece 4, giving 

 a magnification of 61 diameters, was used. This high magnifi- 

 cation is necessary for the observation of the minute sculptural 



characters used.

TABLE OF SPECIES. 



Antennse stout and tapering toward the tip, flagellar joints beyond the 

 second but little longer than wide; ocellar spot nearly or quite sepa- 

 rated from the occipital spot by inward extensions of the yellow orbital 

 ring behind the ocelli ; face largely or wholly yellowish 1 



Antenna? slender not tapering toward the tip, flagellar joints much 

 longer than wide ; ocellar spot and occipital spot broadly confluent . 



1. Body smooth or but very faintly sculptured throughout; antenna; 



in female 13 to 15-jointed (17-jointed, according to Wesmael), 

 in male 20 to 22-jointed (20 to 26, according to Wesmael); ocellar 

 spot almost invariably entirely separated from occipital spot. 



brevicornis (Wesm.) (= hebetor auct. not Say = juglandis Ashm.) 

 Body distinctly sculptured; antennae in female 20 to 22-jointed, in 

 male 23 to 25-jointed; ocellar spot except in very pale specimens 

 not entirely separated from occipital spot variabilis n. sp. 



2. Second tergite with a median embossed area set off at least anteriorly 



by crenulate grooves, its surface differently sculptured from the 

 rest of the tergite (in the male this character is less evident, the area 

 being more narrow and the grooves less distinct); rest of tergite 

 more or less finely, irregularly, longitudinally or reticulately 



rugulose 



Second tergite without an embossed area, granularly roughened, with- 

 out rugae though sometimes with very fine reticulation on the basal 

 middle ^ 



3. Furrows of first tergite narrow and not crenulate, the triangle with- 



out large punctures apically, lateral areas shagreened; second ter- 

 gite reticulate platynotit. n. sp. 



Furrows of first tergite broad and crenulate, the triangle with a few 

 large punctures apically, lateral areas much roughened; second 

 tergite longitudinally rugulose 



4. Mesoscutum with a large quadrate testaceous spot in front of the scu- 



tellum from which lines of the same color extend forward along the 

 positions of the notauli; face in female with broad inward exten- 

 sions of the yellow orbital rings below the antenna?; antennse tes- 

 taceous, infuscated beyond the middle, 23 to 24-jointed, in male 

 (lost, but from the description evidently a poorly developed speci- 

 men) 21-jointed; abdomen in female yellowish, darker laterally 



xanthonolus (Ashm.)
