and in this respect differ from the other species placed in the 

 genus, and, in fact, from all other known Prionidae. 



4. Dialeges undulatus, Gahan. 



Three or four examples. This species was described from 

 examples from Ceylon, Burma, and Siam. 



5. Cerestum sinicum, White. 



One example of this common Chinese species was obtained 

 at Hainan. 



6. Euryhatus lO-punctatus^ Westw. 



One male example. This species has been hitherto re- 

 corded only from N. India, Burma, Java, and Borneo, the 

 last-named locality being very doubtful. Two specimens 

 from Sarawak which Pascoe referred to the species are 

 distinct from the N. Indian and Burmese forms, and probably 

 belong to the Javan species E. Iceta^ Lameere. 



7. Clytanthua Douei, Chevr., var. 

 Three examples. 



8. Chlorophorus annularis, Fabr. 

 This is a very widely distributed Oriental species. 



9. Xylotrechus quadripes, Chevr., var. 



One example. The postmedian cinereous band of the 

 elytra is broader than in the typical form occurring in India, 

 Burma, and Siam. 



10. Monohammus himaculatus, Gahan. 



One example. The species was previously known only 

 from N. India, Burma, and Siam. 



11. Pelargoderus apicaliSy sp. n. 



FuBCUs, supra tenuiter griseo-pubescens ; prothorace lateraliter ob- 

 solete tuberculato, fere mutico, disco subrugoso ; ecutello pube 

 fulva dense obtecto ; elytris basi granulosis, deinde sat dense 

 fortiterque punctatis, versus basin sparsissime, sed in partem 

 tertiam apicalem dense, fulvo-maculatis ; corpore inferiore cum 

 capite femoribusque maculatim fulvo-pubescentibus ; antennis 

 griseo-fulvis, articulis 3° ad 10"'" apice fuscis, articulis 3° ad 5""" 

 vel 6"™ subtus sat dense ciliatis. 



Long. 20, lat. 6 mm. 



Ilab. Hainan {Whitehead).
