length of metanotum (including median segment), 9.2; length of median seg- 

 ment, 1.8; length of cephalic femur, 14.2; length of median femur, 10.3; 

 length of caudal femur, 11.8; length of operculum, 5.8 mm. 



This species is known to us only from the pair here descril)e(l.

The type by monotypy of Oncotupluisiiia is (Irifhni's martini. 

 We here select as genotype of Parddiapheroniera, Brunner 's 

 strumosa. As that species is a synonym of martini, Paradiaphero- 

 mera consequently falls as a synonym of Oncotophasnia. Brun- 

 ner 's lack of knowledge of recent literature here resulted in his 

 overlooking the work of both Griffini and Rehn.

The comparatively slender, smooth and ajiterous males of 

 this insect are readily distinguished by the remarkable swelling, 

 which occupies the caudal portion of the metanotum. 



The extremes in the Gatun series of this very distinctive 

 species measure as follows: 



Length of body, 83 to 92; length of mesonotum, 21.4 to 

 24.9; median width of mesonotum, 1.7 to 2; length of metanotum 

 (including median segment), 14 to 15.8; length of median 

 segment, 4 to 4.8; width of median swelling, 5 to 5.8; length of 

 cephalic femur, 23.8 to 28.1; length of median femur, 18.5 to 

 22; length of caudal femur, 2() to 29; length of cephalic tibia, 26.7 

 to 31.5 mm.
