NOVITATES ZOOLOGICAE XXIII. 1916. 361 



Hab. Toura Kom, Annam, July 1915 (type) ; Keng Trap, Annam, April 1915; 

 Lao Kay, Upper Tonkin, July 1913 ; a small series of both sexes. 



We also have a $ from Phac Son, Annam (H. Fruhstorfer), November — 

 December ; and a number of specimens (<$ ?) from Laos. 



6. Mecocerus asinenus Jord. (1913) 



Mecocerus asmenus Jordan, Rec. Ind. Mus. ix. p. 204. no. 7 (1913) (J 1 , Caohar ; $ , Sadiya). 



1 ? from Keng Trap, Cuerao, Annam, August 1913. 



We have also a <? from Hoa Binh, Tonkin. 



These two specimens differ from the two Indian examples described by me, I.e., 

 in the dorso-lateral basal tawny spot of the pronotum not being continued forward 

 across the carina. 



7. Physopterus oculatus Jord. (1904) 



Phy&opterus oculatus Jordan, Nov. Zool. p. 231. no. 4 (1904) (Tonkin, $ $ ). 



1 $ from Keng Trap, Cuerao, Annam, August 1913 ; 2 ? ? from Chapa, Upper 

 Tonkin, April 1912. 



8. Merarius davidis Fairm. (1889) 



Merarius davidis Fairmaire, Ann. Soc. Eni. France, p. 56 (1889) (Moupin). 

 1 ? from Chapa, Upper Tonkin, April 1912. 



9. Straboscopus tessellatus Eyd. & Soul. (1839) 



Stenocerus tessellatus Eydoux et Soulayet, Rev. Zool. p. 265 (1839) (Manila). 



One small $ from Vientiane, Me-kong, May 1915. 



This species and S. riehli Lac. (1866) resemble each other in colouring very 

 closely. In tessellatus, however, the club of the antennae of both sexes is much 

 more compact, segments 10 and 11 not being narrowed to a point at the base, as is 

 the case in riehli ; moreover, the mesosternal process of tessellatus is widened at 

 the apex and the midcoxae are correspondingly notched, whereas in riehli the 

 process is much more evenly rounded apically, and the midcoxae are without a 

 notch. 



10. Xenocerus salamandrinus nov. sp. 



c? $ . Brnnneo-niger, subtilissime cinereo pubescens, supra et infra maculis 

 luteo-ochraceis nigro marginatis ornatus, antennis pedibusque rufescentibus, illarum 

 segmentis 2°-5° (c?) vel 2°-6° (?) pilosis. 



Hab. Hoa Binh, Tonkin, 1 <$ (type), received from Monsieur H. Donckier de 

 Donzeel ; 1 $ collected by I. Vitalis de Salvaza at Kompong Tool, Cambodja. 



A very distinct species, in the structure of the antenna allied to A", khasianus 

 Jord. (1895), X andamanensis Jord. (1894), etc. 



The tomentum of both the upper- and underside is so short that it does not 

 conceal the colour of the derm. The ochreous buff markings, most of which are 

 bordered with black, the others accompanied by a black spot, are distributed as 

 follows : Ou the upperside of the head two stripes, another, shorter stripe beneath
