typical minute, sparse punctures on the clorso-pronotum and the ves- 

 tigial medial mandibular groove of phyllophagae. A number of 

 females which have been examined vary toward ovlnigris in having 

 the punctures of the transverse discal band of the dorsal portion of 

 the pronotum more uniform in size and larger toward the lateral 

 angle than in the typical phyllophagae. These seem on the whole, 

 however, to be nearer the latter species than ovinigris, and have been 

 referred to it. The specimens include 5 females from Penniu, China. 

 1925, 4 of which are labeled Nos. 130, 232, 263, and 293, respectively, 

 2 from Hangchow, China, X-3-1924 and VII-1925, 1 from Chin- 

 kiang, China, No. 20, 1925, and 1 from Suigen, Chosen, August 19, 

 1923. A male from Nanking, China, X-1-1924 (Jaynes), has a 

 truncate, thickened apex to the clypeal extension, and the tegula is 

 somewhat blacker than usual. 



Material of this species from Chosen has been known for some time 

 to the workers of the Japanese Beetle Project as Gardner No. 3, 

 equalling Clausen No. 1854. Some of the Chinese material from 

 Hangchow, Chinkiang, and Penniu was designated as Jaynes No. 113. 

 One specimen from Chosen labeled Rohwer No. 7 belongs here. As- 

 sociation of the two sexes was made with the aid of collecting data 

 and was confirmed by rearing male and female progeny of known 

 females from China Exp. No. 31. 



21. TIPHIA OVINIGRIS, new species 



Femcde. — Differs from the description of the female of 2)hyUopha- 

 gae only in the following respects. The lateral expansions of the 

 transverse discal band of punctures on the pronotum without three or 

 four punctures which are very much larger than the other punctures 

 in the discal band; punctures at the apex of the discal band, imme- 

 diately anterior to tegula, approximately as large as those mediad 

 of this point; lateral discal punctures of the dorsal aspect of pro- 

 notum somewhat larger than those of the same region in pliyUo- 

 phagae^ being small primaries. Length, 11 to 13 mm.
