This species, type of the genus, has been introduced into the United 

 States from Japan as a parasite of the beetle Popillm japonica 

 Newm., and is now established here. 



The receipt of better preserved material than the types shows that 

 the eyes are hairy, and the generic description should be corrected 

 accordingly. 



KEY TO SPECIES OF CENTETER 



Abdominal segments 1 to 4 broadly shining black on nearly the apical half; 



tibiae and femora black cinerea Aldrich. 



Whole abdomen covered with brownish-gray pollen, slightly tesselated ; tibiae 



and tips of femora reddish unicolor, new species. 



CENTETER UNICOLOR, new species 



Female. — With all the generic characters of cinerea:.., differing as 

 noted in the key. The arista is yellow on basal half; there are no 

 proclinate orbitals, but outside the frontal row there are sometimes 

 one or two small mesially inclined bristles. Three lateral scutellar 

 bristles are present, but the small apical pair of cinerea is absent; 

 hence the third lateral pair might be described as a large apical 

 pair. Eyes distinctly hairy. The front is very wide, being 0.45 of 

 the head width at vertex (as compared with 0.41 in the female of 

 cinerea) . 



Described from four females from Suigen, Chosen (Korea) ; three 

 are labeled " May 13, 1926, col. K. Sato ; " the other " Parasite of 

 Anomala sieversi and Phyllopertha sp." The abdomen of one speci- 

 men has been dissected away to show several large, white eggs, of the 

 same type as in cinerea. 



Type.— Female, Cat. No. 41451, U.S.N.M. 



In conclusion it might be well to add that Sig^elotroxis poirvus 

 differs from both species of Centeter in having bare eyes, the front 

 much less prominent, the parafacial bare above near the facial ridge 

 as well as elsewhere, and the eye considerably larger.
