SCHIZONYCHA AMBIGUA, n. Sp. 



Plate XLVIIL, fig. 46. 



Belongs to the group of S. infantilis and S. puerilis ; it is 

 distinguished from the former by the more arcuate fore margin of 

 the clypeus, and from the latter, the clypeal margin of which is 

 identical, by having a very sharp, transverse carina on the vertex of 

 the head; the shape of the body is similar to that of the two above- 

 named species, but the punctures on the prothorax are not asperous, 

 even close to the sides, and the scutellum is more numerously pitted 

 than in S. ptierilis ; the sculpture of the elytra is very nearly the 

 same, but the propygidium is finely punctate in the lower half, and 

 the pygidium is more deeply punctate than in S. puerilis, resembling 

 thus that of S. infantilis. The genital armature is much more 

 like that of S. puerilis, the forceps are symmetrical, but of equal 

 length and width, and the shape of each branch is that of the left 

 one of S. puerilis, but twice as wide. 



Length 10 mm. ; width 5 mm.
