286 THE CANADIAN ENTOMOLOGIST 



rounded; sternum light yellow. Hypopygium (see fig. 1 and 2, 

 plate X). Pleurites short and broad, the caudal end produced into 

 one fleshy and three chitinized appendages, as follows: Viewed from 

 above, a fleshy lobe in front, the inner dorsal margin produced en- 

 tad and dorsad into a slightly curved slender spine; behind the 

 fleshy lobe arises a stout hook, very strong at the base, constricted 

 before the middle, the tip slender and pointed, this hook directed 

 entad and caudad; from the outer ventral angle of the pleurite 

 arises a long, straight chitinized appendage, directed entad and 

 caudad, narrow basally and more enlarged apically. The guard of 

 the penis is long, pale, ending in a long, slender, tube-like point. 

 On either side of the penis guard arises an elongate, very slender, 

 chitinized hook, which is straight for about three-fifths its length 

 and then bent stroii,gly inward; viewed from the side, these hoops 

 are bent ^'ery strongly ventrad and then caudad. Summarized, 

 the hypopygium bears eight chitinized slender arms, all except two 

 (which are probably homologous with the second gonapophyses) 

 being borne by the pleurites. 



Female. — Very similar to the male, but larger.
