206 NEW EECOEDS & SPECIES OF MALAYAN MEMBKACIDAE. 



2. Leptocer.trus leucaspis Walker. 



Add — Locality: Sandakan, Borneo. 



One female bearing Baker's duplicate No. 9509. This speci- 

 men is somewhat larger and darker than the forms of the species 

 taken at Singapore but I can find no specific differences. It may 

 be a separate variety but could not be so designated on a single 

 specimen. 



3. Leptocentrus obortus Distant. 



Add — Locality: Sandakan, Borneo. 



One specimen (Baker's duplicate ^"o. 940 7) agreeing in all 

 respects with an unnumbered specimen from Singapore. 



4. Leptocentrus Jongispinus Distant. 



Add — Localities: Sandakan. Borneo: island of Penang. 

 Two specimens, both males, one from Borneo and the other 

 from Penang, differing slightly in the amount of divergence of 

 the pronotal. horns, the one from Borneo showing somewhat the 

 wider spread across the tips, but otherwise similar. 



5. Centrotypus securis Buckton. 



1903. Centrotypus securis Buckt. Mon. Memb. p. 238, 

 PI. 54, Fig. 4. 



1907. Centrotypus securis Dist. Fauna Brit. Ind. p. 34, 

 No. 2147. 



1916. Centrotypus securis Dist. Fauna Brit, Ind. App. 

 p. 156. 



One male and two females, all from Sandakan, Borneo. If I 

 am determining this species correctly, it is very close to Centrotypus 

 flexuosus Fabr. The suprahumeral horns are longer and the teg- 

 mina slightly different in colour. 



6. Centrotypus asmodeus Distant. 



Add — Locality: Sandakan, Borneo. 

 Two males and one female. 



7. Centrotypus shelfordi Distant. 



1916. Centrotypus shelfordi Dist. Ehynch. Xotes p. 315. 



One male (Baker's duplicate No. 9822) taken at Sandakan, 

 Borneo. This species should be easily recognized by the very wide- 

 spreading laminate suprahumeral horns.
