as long as funicle, first and second segments together comprising much 
more than half of length, first and second sutures transverse, partially 
septate, third suture indicated by row of setae. 
Pronotum 1.15 times as long as wide, widest near base, posterior 
outline weakly arcuate, distinctly margined, posterior angles rounded ; 
sides weakly arcuate from base to anterior lateral constriction, mod- 
erately rounded in front, with anterior margin weakly serrate; dorsal 
contour evenly arcuate from base to apex, without elevated summit 
or transverse impression; anterior area with asperities in irregularly 
concentric rows, continued at sides nearly to base; posterior area 
strongly punctured, usually with lateral rim of each puncture elevated ; 
median line narrow, elevated; vestiture of short, stout hairs, often 
somewhat spatulate. 
Elytra distinctly wider than pronotum, 1.34 times as long as wide, 
1.30 times as long as pronotum; sides subparallel on anterior half, 
then gradually arcuately narrowed, very broadly rounded at apex; 
surface shining, feebly reticulate; first stria impressed, the punctures 
in fairly regular rows, rest of disk and sides confusedly punctured, 
with all punctures about equally deep and coarse, many of them (from 
interspaces) with short, stout hairs, often spatulate, especially on 
sides and behind. Declivity sloping, originating slightly behind 
middle of elytra, distinctly sulcate; suture rather narrow, slightly 
elevated; first stria strongly, second stria feebly impressed, with in- 
tervening second interspace forming fundus of sulcus; lateral eleva- 
tions much higher than suture, with third and more lateral interspaces 
strongly punctured and bearing stout, erect, spatulate hairs, not so 
conspicuous as in apuleiae Costa Lima. 
Male——vVery similar to female in habitus; frons more shining, less 
closely punctured, with very small, inconspicuous hairs; median carina 
more strongly, sharply elevated; elytral declivity with suleus shghtly 
deeper. 
Spermophthorus caesalpiniae is rather closely related to S. apuleiae 
Costa Lima, of which I have a single specimen taken from the seed 
of Caesalpinia ferrea from Brazil. The most easily recognized dif- 
ferences concern the vestiture of the elytra, which in apuleiae is more 
conspicuous, with the individual setae more flattened and scalelike. 
Differences in the frons, elytral declivity, etc., are also present but 
are not so conspicuous; also the elytral punctures are in nearly regular 
rows. 
Type locality —Paraguay. 
Host.—Caesalpinia melanocarpa. 
Type material—Holotype, allotype, and four paratypes, U.S.N.M. 
No. 56011. 
The type series bears the data labels, “Paraguay, 6054; Caesalpina 
(sic) melanocarpa.”
