schaeffer: donaciini of the new world. 105 
but rounded; ante-median impressions distinct; post-median impressions 
feeble or absent; serial punctures moderately large, finer towards apex; 
intervals transversely strigate from base to apex, near apex the strigation 
is finer and denser, frequently the basal part around the scutellum smooth 
and feebly strigate; in addition there are more or less distinct coarser 
rugae which extend from interval to interval and which are generally 
more evident in the anterior impressions. 
Body below densely and finely punctate; pubescence white, short 
and moderately dense; pubescent space near anterior coxae small, inter- 
coxal process of mesosternum slightly less than half of the width of the 
cavities; posterior femora reaching the apex of the third ventral segment, 
armed below with a moderate tooth in both sexes. Length: 6-9 mm. 
Male: Last dorsal and ventral segments truncate at apex, the 
latter slightly impressed at middle of apex, the former occasionally 
feebly emarginate at apex. 
Female : Last dorsal segment broadly rounded at apex ; last ventral 
segment somewhat sub-triangular and entire at apex.
