HELOTA FRUHSTORFERI. 119 



3 rd striae become slightly costiforin posteriorly and extend 

 down to the hind margin of the elytra; the interstices 

 between the 6 th and 10 th striae are narrower and costiform 

 and alternately more strongly raised as well as extending 

 farther backward; the shoulders and the bronze green 

 elytral epipleurae are impunctate. 



Abdomen smooth, with a few minute hair-bearing punc- 

 tures along the middle ; the apical ventral segment is trans- 

 verse, faintly impressed along the middle, truncate poste- 

 riorly, the lateral angles of the truncation broadly rounded. 



Anterior tibiae on the inside slightly swollen near the 

 base, thence strongly and regularly curved, the upper 

 margin of the curvation terminating in a flattened short 

 black prolongation which is angularly notched just before 

 the obliquely truncated tip; at the apex of the tibia, just 

 above this prolongation, a black tubercle is present; the 

 lower margin of the curvation is black on its apical two 

 thirds. Posterior tibiae straight, as long as the femora of 

 the same pair of legs. 



Hab. Tonkin: Than-Moi (H. Fruhstorfer). — The de- 

 scribed male-specimen belongs to the collection of Mr. 

 René Oberthür. 



Helota tonkinensis, n. sp. cf and Q. 



Very closely allied to and strongly resembling Helota 

 sinensis Oil. a ), from Shantung (North China), but differing 

 by the less strongly convex lateral margins of the prothorax 

 which makes the thorax narrower, by the more coarsely 

 and more densely punctured raised patches on the pronotum, 

 by the much more acutely prolonged apices of the elytra 

 in the female, etc. 



Length 8,5 — 9 mm. — Above rugose in consequence of 

 a very dense punctuation, provided on the elytra with 

 glossy black warts or tubercles of different size and shape
