8 PKOCEEDINGS OF THE NATIONAL, MUSEUM vol.75 



little longer than wide, second as long as wide, others subequal in 

 length and slightly transverse; ninth and tenth more prominent 

 anteriorly; eleventh oval and about the same length as the tenth. 



Pronotum nearly similar to that of lacerta, but with the median 

 discal impression more or less obsolete near the middle, with basal 

 pit deeper and rather more circular. The latter bounded laterally 

 by rather prominent margins that are somewhat faceted lateroposte- 

 riorly at point of contact with the basal elytral processes. 



The antennal fossae extend further posteriorly than in lacerta to a 

 little distance behind the middle; their inner margin very moderately 

 reflexed. Disk broadly impressed behind the fossae and within the 

 reflexed lateral margin; the impressions extend inward along the 

 basal margin to the sides of the basal pit, are shallow and not 

 abruptly formed, with surface subglabrous. 



Prosternal process truncate and flush with the posterior border of 

 the coxal cavities, as well as strongly margined against the acetabula. 



Elytra coarsely sculptured, punctures large in regular series and 

 moderately deep. Intervals more or less discernable throughout 

 between the rows of punctures; the third, fifth, seventh, and ninth 

 rather moderately subcostate in greater part of their length; the 

 third being so for its entire length and terminating in the apical tumes- 

 cence, much thickened at base and joining the feebler parascutellar 

 ridge from the sutural interval, the two together forming a moderately 

 prominent and anteriorly projecting short process that overhangs 

 the basal pronotal margin, evidently abutting against the dorsolat- 

 eral facet on side of the basal pit when the prothorax is retracted 

 against the elytral base; laterally the process is continuous with the 

 basal margin, but abruptly formed medially, somewhat flattened and 

 moderately arcuate at apex. The second interval is not convex 

 anteriorly and is lost between the first and third behind the basal 

 process; seventh interval (fig. 1, E) is moderately costate, beginning 

 just behind the intrahumeral impression and terminating posteriorly 

 with the fifth in a small tuberculiform swelling at summit of the 

 apical declivity. The sixth and eighth intervals are noticeably 

 feebly convex, but irregular from the adjacent strial punctures; ninth 

 is costate throughout and submarginal and not tuberculate at side of 

 the apical declivity. The epipleural margin on the deflexed sides of 

 the elytra meets the ninth interval at the humeral angle. The 

 humeral margin is moderately reflexed and the angle obtuse; the 

 intrahumeral impressions are glabrous as well as the triangular 

 periscutellar space which is slightly anteriorly declivous and usually 

 quadripunctate. The scutellum is minute, elongate, and enters but 

 feebly or not at all between the elytra. 



Abdomen almost impunctate toward the sides, especially in the 

 lateroposterior portion of segments one and two, which are much
