Characters. — This genus does not differ from Mycdophila in any particular excepting in the 
possession of three ocelli, thejniddle one very small, and in the form of the genitalia, which in the 
male are very large and husk-like. In the female the ventral posterior margin of the sixth abdominal 
segment is provided with a row of long setae which project beyond the tip of the abdomen. In an 
American species (2) the forceps are as shown in PI. 7, Fig. 18.
