from females taken in the same locality in 1926. This species has 

 been known to workers of the Japanese Beetle Project as Clausen No. 

 1852 and as Gardner No. 1. In the specimens from Kowai, Japan, 

 the median carina of the propodeal areola is present only on the 

 upper half, while in the Chosen form it is usually developed on the 

 upper four-fifths. The females collected by Clausen at Suigen. 

 Chosen, August, 1923, differ from the others in having the tibiae 

 wholly red and the femora broadly castaneous on the inner sur- 

 face. Although the adults of this species vary but slightly from 

 asericae^ the biological characters determined by Clausen and Gard- 

 ner in Chosen serve to distinguish it quite clearly from the latter.

The following descriptive notes are supplementary to the original 

 description. 



Female. — ^Vertex with a broad, median patch of minute punctures 

 extending forward on dorsum for a short distance from the occipital 

 region. Clypeus with its lateral margin nearly straight. Mandi- 

 bles without an uninterrupted median groove. Punctate portion of 

 the pronotum distinctly narrower at its middle than the impunctate 

 apex ; impunctate apex medially, usually with from one to three or 

 more short, indistinct, longitudinal grooves. Metanotum usually 

 with a sparsely bipunctate, shallow, median impression, with its 

 coarser punctures nearly as large as those of the scutellum. Legs 

 with major calcarium of the hind tibia broadest just before the mid- 

 dle; hind basitarsus on the outside with a row of three lanceolate 

 spines, one of which is at apex. First tergite with a small medial 

 patch of minute punctures on anterior slope. Lateral grooves of 

 first sternite present on posterior half or less. Tergites 2 to 4 with 

 wide, impunctate apices, medially at least one-fifth as wide as the 

 punctate portion; no trace of a row of vestigial apical punctures or 

 of a marginal linear groove over the dorsum. Pygidium reticulo- 

 punctate on basal two-fifths, the impunctate apex wrinkled but not 

 shagreened; the punctate portion with a well-marked jmpunctate 

 emargination. 



Male. — ^Vertex usually invaded from behind by dense, minute punc- 

 tures scattered over an area wider than ocellar triangle. Preocellar 

 area of front with its widest interspaces not quite as wide as an
