18. Basitropis persimilis spec. nov. 



c? ? . B. nitidicuti Jekel (1855) simillima, sed antenna clava angnstiore, pygidio 

 lanoso sine vitta brunnea mediana, tibiisque ante apicem immacnlatis. 



Hab. Vientiane, on the Mekong, May 1915 (type) ; Kompong Kedey, province 

 of Kompong Thorn, Cambodja, April— May 1914, a series. In the Tring Museum 

 also from Malacca and Tenasserim. 



As in B. nitidicutis, the rostrum is at least twice as broad as it is long, and 

 bears a thin median carina, which is more or less irregular on account of the 

 coarse puncturation, and extends well on to the broad frons. The antenna likewise 

 resembles that of nitidicutis, the club consisting of four segments in the S , the 

 preceding segments gradually decreasing in width ; segment 8, however, is con- 

 siderably smaller than 9, resembling the latter much less than it does in nitidicutis. 

 The lateral carina of the prothorax is somewhat straighter if viewed from the side, 

 and the pygidium, on account of the longer woolly hair with which it is covered, 

 has the appearance of being more convex than in nitidicutis. In colour 

 persimilis differs from nitidicutis especially in the absence of a brown median 

 stripe or patch on the pygidium and of a brown subapical spot on the tibiae. The 

 luteous grey spots and patches on the pronotum and elytra are in most specimens 

 of persimilis smaller and better defined than in nitidicutis. 



19. Phloeobius pallipes Jord. (1895).

 1915; Chapa, via Lao Kay, Upper Tonkin, April 1912.
