the inner lateral margin of the basal article, about the middle, and 

 both extend to the extremity of the basal article. 



This species is larger than any of the other three known species of 

 the genus described by Dollfus, being 9 mm. in length, while the 

 other three are but 4, 5, and 6 mm. in length. It seems closer to 

 T. cephalica Dollfus ^ than to the other two described by that author. 

 From the figures of the three species shown by Dollfus, the head is 

 carinate on the dorsal side, while in the species just described, the 

 dorsal surface is perfectly smooth. T. celebensis and T. gorgana 

 both have the body strongly tuberculate, while T. cephalica is slightly 

 tuberculate anteriorly. T. dollfusi has the body perfectly smooth. 

 Budde-Lund ^ mentions a fourth species of this genus, T. conglobator^ 

 which, in the short description he gives, he refers to it as having the 

 epistome plain. He includes Periscyphus weberi Dollfus in this genus. 



Eleven specimens of this species were collected at NongkodjaJjar, 

 Java. 



The type is in the United States National Museum (Cat. No. 

 64475). The cotype is in the Ley den Museum.
