NEW KECOBDS & SPECIES OF MALAYAN MEMBRACIDAE. 211 



17. Tricentrus albomaculatus Distant. 



Three females, one from the Island of Penang (Baker's dupli- 

 cate Xo. 9388) and two (one bearing Baker's duplicate No. 9406) 

 from Singapore. This species has been previously reported from 

 both these localities 1 as well as from other parts of South India 2 

 and is apparently common throughout the Peninsula. 



18. Tricentrus brunneus Funkhouser. 



Add — Localities: Sandakan, Borneo; Island of Penang. 



Two specimens, both females. It is interesting to note that 

 this species was described from a female from Singapore 3 and that 

 the male has never been recorded. The suprahumeral horns in the 

 Borneo specimen are slightly longer than in the type specimen but 

 I can find no specific differences. 



19. Tricentrus assamensis Distant. 



One male (Baker's duplicate No. 9403) from Singapore. The 

 species which I am determining as assamensis is apparently subject 

 to considerable variation and has a wide range. It has previously 

 been reported from Singapore 4 ; Distant records it from Assam 5 and 

 I have a series from Teppakulam collected by the Eev. L. V. Newton 

 in 1915. The variation shown in the specimens from different dis- 

 tricts is chiefly in size and I can find no characters which would 

 warrant the splitting of the species in the material at my disposal. 



20. Tricentrus repandus Distant. 



1916. Tricentrus repandus Dist. Fauna Brit. Ind. App. 

 p. 163, No. 3362. 

 Two females, one from Sandakan, Borneo, and one from the 

 Island of Penang. This species has not been previously reported 

 from either of the above localities.
