A number of specimens have vestigial lateral carinae on the con- 

 stricted part of the first sternite, but these are not as high as in 

 stemocannata, and the interval between them and the medial carina 

 is definitely coriaceous, and is not as deeply grooved. To this species 

 and variety have been referred Clausen's material under his number 

 1855, which equals Gardner's number 4, and also a part of the ma- 

 terial under Gardner's number 13, which included specimens of 

 popilliavora as well. 



The notopolita group, including the two varieties and the closely 

 related rufoirumdihulata and sternocarinuta, have furnished one of 

 the most puzzling problems connected with any of the TipMa con- 

 sidered in this paper. Individual females of the two varieties, which 

 might easily be considered of two different species, can be picked out, 

 but intergradients are numerous, and varietal rank seems the highest 

 to which they should be assigned. Male genitalia of the two varie- 

 ties and of rufomandibvlata have been studied, and show no differ- 

 ences of importance.

The following notes were made from a study of specimens com- 

 pared by Mr. Gahan with the type female from " Hiogo," Japan. 

 Mr. Gahan, however, did not have specimens of either of the closely 

 related varieties of notopolita with him at the time of comj)arison.
