and in tliis respect differ tVoin the other .species placed in the 

 genus, and, in tact, from all other known Prionidfe. 



4. Dialeges imdulatus, Gahan. 



Three or four examples. This species was described from 

 examples from Cejlon, Burma, and Siam. 



5. Ce7'estuni stnicum, 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 tlie Javan species E. Iceta, Laraeere. 



7. Clytanthus Douei, Chevr., var. 

 Three examples. 



8. Cklorophorus 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 bimaculatus, Gahan. 



One example. The species was previously known only 

 from N. India, Burma, and Siam.

 solete tuberculato, fere mutico, disco subrugoso ; scutello pube 

 fulva dense obtecto ; elj-tris basi granulosis, deinde sat dense 

 fortiterque punctatis, versus basin sparsissime, sad in partem 

 tertiam apicalem dense, fulvo-maculatis ; corpore inferiore cum 

 capite femoribusque maculatim fulvo-pubescentibus ; antennis
