132 ßradley, A new Thynnid Wasp from Brazil. 



finely puncturecl. The pleural sclerites are closely punctured ; 

 the mesopleura has a posterior transverse Impression near its 

 middle. A läppet projects from each side of the mesostermim 

 between the middle coxae, the two together forming a subtriangular 

 process ; the posterior coxae are approximate. The propodeura 

 is oblique , polished and shining , but with minute subobsolete 

 punctures, larger and sparser on the sides ; spiracle large, slit-like. 

 Venation of the wings as figured. Middle tibiae with t.Avo 

 apical spurs ; middle and posterior tibiae and tarsi irregularly 

 spinöse and covered with short pubescence, while the femora are 



nearly glabrous and sparingly punctured ; inner posterior tibial 

 spur sinuate ; the posterior tibia is a little longer than the 

 femur , the tarsus a little longer than the tibia , the metatarsus 

 barely shorter than the following segments united ; tarsal claws 

 large, bifid, the outer ray slender. 



Abdomen long and slender, longer than the head and thorax 

 uüited, each segment somewhat swollen posteriorly , so that the 

 constrictions between the segments are piain ; pygidium truncate, 

 slightly notched in the middle, with sharp latero-dorsal carinae ; 

 hypopygium spatulate, but neither toothed nor produced distinctly 

 beyond the apex of the abdomen. Dorsal segments shallowly 

 punctured ; ventral segments posteriorly each more coarsely 

 punctured ; sides and venter of abdomen posteriorly bearing coarse 

 black bristles. 



I have written the above description to fit generic as well 

 as specific characters in some detail , since I believe that this 

 species is as distinct from the known species of Ornepetes as are 

 many of the so called genera that are recognized today, and may 

 eventually require the erection of a new genus or subgenus. 



Described from eight male specimens caught by Mr. A. G. 

 H a m m a r in virgin forest in the Serra Canthareira near Sao Paulo, 

 Brazil, March 20, 1903.
