Two females, one from Singapore and one (Baker's duplicate 

 Xo. 9386) from the Island of Penang. Since this species was 

 originally described from Hindustan 1 and has since been recorded 

 from Barjeeling (Mann), Calcutta and Tenasserim (Doherty) 2 , 

 it apparently has a wide range. The specimens from the Singapore 

 region seem to answer fully the original description by Walker and 

 the more recent description by Distant and if they are not congestus 

 they are so near it that it would he unwise to consider them as new 

 and they must accordingly be placed temporarily at least under this 

 species. 



22. Tricentrus resectus Distant. 



Add — Locality: Sandakan, Borneo. 



Five specimens, one (Baker's duplicate Xo. 9404) from Sing- 

 apore and four (two of which bear respectively Baker's duplicate 

 Xos. 9394 and 982?) from Borneo. All of the specimens are 

 females but the male has been previously recorded from Singapore^ 



23. Tricentrus gibbosulus Walker. 



A del— Locality : Sandakan. Borneo. 



A series of twenty specimens collected as follows: two males 

 from Singapore (one bearing Baker's duplicate Xo. 9405) ; four 

 males and two females from the Island of Penang, two of the males 

 bearing Baker's duplicate Xos. 9382 and 9383 respectively and two 

 of the females 9385 and 938? respectively; five males and seven 

 females from Borneo, the males including Baker's duplicate Xos. 

 9517 and 9518 and the females Xos. 9318, 9516 and 9828. 



The species has already been reported from Singapore and the 

 Island of Penang at which localities they were collected by Pro- 

 fessor Baker during the .Summer of 1917. 



The males of this species are somewhat smaller and darker 

 than the females and both sexes show some variations in the length 

 and position of the suprahumeral horns.
