28(5 THE CANADIAN ENTOMOLOGIST 



rounded; sliTiiuin liglit \cllo\v. Hypopygium (see fig. 1 and 2, 

 plate X). Pk'iiriics sh(/rt 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, \ery strong at the base, constricted 

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

 cntad and caudad; from the outer \entral angle of the pleurite 

 arises a long, straight chitinized appendage, directed entad and 

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

 the |)(iiis is long, pale, ending in a long, slender, tube-like point. 

 ( )n citlier side < f tiie penis guard arises an elongate, very slender, 

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

 and then bent strongly 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 niali-, but larger.
