Catcin Cauri in Upper Burma , and Garin Mts. , district of 

 Gheba. The Chinese examples upon which this species was 

 founded were in all probability (so M.'' Bowring informs me) 

 obtained at Hong Kong or its immediate neighbourhood. 



20. Hoplocerambyx spinicornis, Newm. — flammaticherus spi- 

 nicornis, Newm., The Entomologist I (1842) p. 245. 



Thagatà in Tenasserim ; one male example. This species oc- 

 curs also in the Philippine Islands (type) ; and in North India — 

 Allahabad and Nepal (Brit. Mus. collection). Examples from 

 Borneo, constituting the //. morusus of Pascoe, do not seem to 

 me to offer any definite characters by which they can be distin- 

 guished from the above. The species appears to be subject to 

 great variation in size.

Malewoon in Tenasserim. One small example. The localities 

 indicated above, to which may be added Siam and Java, evi- 

 dence the wideness of distribution of this species. Whether it is 

 an Oriental species, which has been transported to West Africa, 

 or an African species which has been carried to the East, I 

 am unable to decide. 



22. Pachydissus [Margiles) exiguus, sp. n. Fuscus, griseo leviter 

 pubescens; ante?mis pedibusque piceo-rufescentibiis, pube grisea le- 

 nuiler obtectis; proLhorace supra intricate hand fortiter rugoso, 

 lateribus irregulariter rotu?idatis; antennis quam carpare paullo 

 longioribus, arliculis 3" et 4° apice vix incrassatis, 3° quam 1° 

 vel 4° paullo longiori. Long. 11 mm,. 



One example taken at Mandalay. This species resembles 

 P. (Margites) egenus. Fase, in coloration, but is of much smaller 

 size. The prothorax has a thin unicolorous greyish pubescence.
