On new Genera of Ichneumonide. 523 
Pathocerus Wagneri, sp. n. 
Elongatus, pallide piceus, nitidus; thorace disco sat planato, sat 
crebre evidenter punctato, lateribus impressis, confertim subtilius 
punctatis ; elytris crebre sat fortiter punctatis, quadricostatis, 
singulo ad apicem spina brevi armato; pectore fulvo-pubescenti. 
Long. 30 mm. 
Hab. Rio Janeiro, Cerra das Organas (4. 2. Wagner). 
The antenn have the two basal joints shining, the rest 
are entirely dull; the eleventh joint is one third the length of 
the whole antenna, compressed, curved ; the branches of the 
preceding joints resemble the eleventh joint in form, but 
diminish. gradually in length from the ninth to the third. 
The thorax is rather flat on the disk, impressed at the base, 
moderately closely punctured; the sides slope away from the 
disk and are densely and more finely punctured ; the reflexed 
margins, however, are smooth. ‘The elytra are slightly 
dilated below the shoulders, rather closely and strongly 
punctured, and towards the sides and apex obliquely rugulose.
