10. Leptatjlax dentattjs, Fabr. 



, The typical small form was obtained from Sikkim, Butan, Assam, Te- 

 nasserim (at Mergui) and from Johore. In the Vienna collections it is repre- 

 sented from nearly all the Philippine islands. 



The larger form, or L. Tlmorensis, is also very abundant in Sikkim 

 (between 500 and 1000 feet), Butan, Assam, Naga hills, Pegu (near Ton- 

 ghu), and on the Andaman islands. It grows up to 37 m.m. I had very 

 large numbers of both forms for comparison, and came to the conclusion that 

 no definite characters exist by which the two species could be separated. I 

 have all intermediate sizes from 21 to 37 m.m. 



11. Leptaulax bicoloe, Fabr. 



Very common in Sikkim and through the whole of the Malayan Penin- 

 sula, as well as on the Andaman and Nicobar islands, in Malabar and in 

 Ceylon. Form the last localitytwo specimens exist in the Vienna Museum 

 collection under the name of Nietneri, M. C. 



A peculiar small variety, possessing cross bars in the lateral furrows of 

 the elytra, instead of simple dots, occurs at Johore. 



12. Leptaulax planus, IHig. 



This is, I think, a good species, the smallest of all our eastern Passali- 

 D^. It is very much more depressed, than either of the previous species, 

 and in proportions and relative size of the prothorax and of the elytra it 

 more closely resembles dentatus than hicolor, of which it is stated to 

 be a synonym. Specimens from Java, Johore, and Malacca, whence I 

 have lately obtained large numbers, measure between 13 and 14 m.m., but a 

 somewhat larger variety occurs in Burma and on the Andaman islands. 

 Specimens from these last localities measure 18 m.m., they are in almost 

 every other respect identical with t^Yicdl planus.* 



Of the third group, the Eriockemiis'^, no species as yet occurred within 

 our limits. I received Vellejus Moluccanus from Amboina, Eriocnemis 

 monticulosus from Sumatra, and gigantic specimens of Erioe. tridens from 

 Java, but none from Siam or Malacca, which localities are also given by 

 Kaup. The last species will have, therefore, to be included in our list. 



Fourth group. MACEOLrN"^. 



13. Macrolenus latipennis, Perch. 

 Malacca ; apparently rare. 



14. Macrolinus Weberi, Kp. 



Johore ; a single specimen from Mr. J. Wood Mason. 



* In Dr. Felder's collection I find a Malacca specimen named j^Ofljitw*.?
