dially four to six times the diameter of largest adjacent primary 

 punctures. Length, 6.5 mm. 



DistHhution. — Assam, India. 



Type and allotype. — Cat. No. 41802, U.S.N.M. Type, female, and 

 allotype, male, Shillong, India, Jap. Beetle Par. Exp. 302-0. 



Paratypes. — All from Shillong, India. Deposited in the U. S. 

 National Museum : One female and 3 males, Jap. Beetle Par. Exp. 

 202 ; 3 females and 45 males, Jap. Beetle Par. Exp. 302-0 ; 6 females 

 and 25 males. Retained in the collection of the Japanese Beetle 

 Laboratory: One female and 2 males, Jap. Beetle Par. Exp. 302-0. 

 Deposited in the collections of the British Museum, the Illinois 

 Natural History Survey, and the Philadelphia Academy of Natural 

 Sciences: In each, 1 female and 2 males of the same lot as the last. 



The association of the sexes has been made through the rearing 

 of adults from field-collected cocoons obtained at Shillong (Exps. 

 202 and 302-0). The males corresponded in abundance and in time 

 of emergence with the females. There were three other species reared 

 from this material, but in very much smaller numbers and at a 

 different time of the year. 



This species has been known to workers of the Japanese Beetle 

 Project as Clausen No. 2049.

Female. — Vertex with primary punctures of second-degree density 

 delimiting irregular impunctate spaces. Punctures slightly denser 

 medially than on either side. Front polished, with broad impunc- 

 tate stripe extending up to ocellus ; carina and groove usually absent ; 

 primary punctures with tendency toward arrangement in irregular 

 rows, frequently with, two, and at places more interspaces, exceeding 

 diameter of punctures; preocellar area with several interspaces as 

 broad as ocellus. Clypeal extension with clearly defined impunctate 

 apex, the longitudinal extension of which equals two-fifths the 

 distance from apex of clypeus to base of antennae. Flagellum of 

 antenna fulvous beneath. Pronotum with its transverse carina 

 usually complete, though weakly developed; primary punctures of 

 uniform size, and well differentiated from secondaries, much denser 

 medially and in transverse discal band than on lateral disks ; second- 

 ary punctures numerous medially ; punctate portion medially slightl}' 

 narrower than the impunctate portion. Side of pronotum broadly 

 and weakly striate, usually with one barely perceptible groove in the 

 middle equal to one-half the length of the sclerite, and with numer-
