300 DYNASTIN^. 



Lenrfth 15-5-17'5 ram. ; hreadth 8*5-9-5 mm. 

 Assam : Silhet, Patkai Mts. 

 Type in the British Museum. 



272. Alissonotum rangunense, sp. n. 



Black, smooth and shining, rather narrowly elongate and convex. 

 The head is rugose, narrow and bidentate in front, with a pair of 

 tubercles placed rather close together in the middle. 1\\q irronotum 

 is strongly but not closely punctured, without anterior impression 

 or tubercle, and boldly and regularly rounded at the sides. The 

 scuteUum is smooth and the elytra are deeply punctate-striate, the 

 apical margins closely and irregularly punctured and all the 

 punctures annular and I'ather coarse. The stridulatory files of the 

 propyriidium are rather divergent and the jyyr/idium is coarsely but 

 not very closely punctured. The lower surface is almost smooth, 

 but there are a few large punctures at the sides of the metasternum. 

 S . The inner claw of the front tarsus is a little thickened and 

 strongly bent. 



Length 9-11 mm. ; hreadth 4*5-6 mm. 



Burma : Pegu, Kangoon. 



Type in the British Museum. 



This is one of the smallest known DYXA.STix.i: and the smallest 

 dealt with in this volume. It is extremely like Alissonotum 

 crihratellum, Fairm., from Cochin China and the Malay Peninsula, 

 in which the front claws are perfectly normal and similar in both 

 sexes. 



273. Alissonotum simile, sp. n. 



Black, smooth and sliining, convex and elongate-oval. The head 

 is like that of A. rangunense, but the ante-ocular ridges are a little 

 more prominent. The pronotum is strongly punctured and the 

 punctures are dense at the sides. There is no anterior impression 

 or tubercle. The scutdlam is smooth and the elytra are vei-y 

 coarsely and deeply punctured in rows, the apical margins being 

 closely and irregularly punctured. The stridulatory files of the 

 jrropygidhim diverge rather strongly at their ends and the jw/^u^m?H 

 is coarsely and rather closely punctured. The luwer surface is 

 nearly smooth, but there are some large punctures at the sides of 

 the nictastennnu. 



The front claws are alike in both sexes. 



Length 10-11 mm., breadth 5"5-6 mm. 



Assam : tSilhet, Dilkoosha : Bengal : Pusa. 



Tyjie in the British Museum. 



This species is extremely like A. rangunense and A. crihrateUum. 

 It is a shade larger and less elongate than the former, the punc- 

 tures of the elytra are rather coarser, those of the pronotum more 

 crow-ded at the sides and those of the pygidium rather more
