more strongly convex in dorsal profile, less strongly convex in ventral 
profile than peninsularis, much as in pustulatus. Total length, 2.49 
mm; greatest width, 1.80 mm; width at base of pronotum, 1.60 mm; 
width at apex of pronotum, 1.02 mm; length from base of prosternal 
process to apex of coxal lamina, 1.10 mm; width between eyes, 0.69 
mm. Head microreticulate much as described in inexpectatus but 
meshes somewhat less impressed, the surface appearing more shiny; 
clypeal tubercles reduced; clypeo-frontal grooves more closely and 
heavily punctate; punctures along inner margins of eye difficult to 
see, apparently not setigerous; clypeal margin distinct, feebly truncate 
at middle, and bordered behind by an indefinite groove; punctation 
fine, sparse, and irregularly distributed. Pronotum microreticulation 
coarser and more deeply impressed than on head but surface mod- 
erately shiny ; punctation on disk coarse and dense compared with 
that on head, rather uniformly distributed but irregularly spaced; 
anterior row of coarse punctures not readily distinguished from discal 
punctation; punctation finer toward margins; sides distinctly mar- 
gined, gently curved, anterior angles moderately acute; angle of pro- 
notal margin with elytral obtuse but less so than in inexpectatus , about 
as in pustulatus. Elytra microreticulate about as on pronotum, meshes 
not deeply impressed, the surface moderately shiny; punctures coarser 
than on pronotum, more regular in size, and having a tendency to form 
irregular rows although not nearly as coarse nor with intermediate 
series of punctures forming such distinct rows as in concolor; humeri 
moderate, a feeble, punctate groove behind them above a feeble ridge ; 
both groove and ridge more evidnt than in pustulatus but much less 
evident than in concolor. V enter: Prosternal process triangular with 
anterior end truncate ; distinctly but narrowly margined at sides ; disk 
punctate with inconspicuous microreticulations. Hind coxae and coxal 
lamina with very coarse, dense punctation, the punctures separated by 
less than the diameter of a single puncture and sometimes confluent; 
interspaces with irregular rugose sculpture but moderately shiny. First 
visible abdominal sternite and 2nd (fused with 3rd) with coarse 
punctures much as on coxae; interspaces with rugose sculpture repre- 
senting the coarse, deeply impressed meshes of the microreticulation 
evident on other abdominal sternites; meshes of abdominal microretic- 
ulation elongate; last visible sternite acuminate behind, the tip 
deflexed. Anterior and middle tarsi moderately expanded, slightly 
more so than in female. Middle tibiae rather coarsely and densely 
punctate on anterior face, the punctures setigerous and irregular in 
shape. Antennae (fig. 11) with 3rd through 6th segments conspicu-
