HELOTA TONKINENSIS. 121 



two innermost striae of punctures only are regular, on the 

 rest of the elytra the punctuation is irregular. 



Underside: the triangular middle portion of the head 

 sparingly covered with fine though distinct punctures, the 

 sides densely punctured, the throat impunctate; the middle 

 portion of the prosternura in front of the anterior coxae 

 sparingly and finely punctured ; on the lateral portions the 

 punctures are very distinct; the intercoxal part of the pro- 

 and mesosternum is sparingly punctured and indistinctly 

 wrinkled which makes its surface uneven, the lateral margins 

 are sharply raised ; the metasternum is impunctate in the 

 middle, distinctly punctate at the sides, an impressed line 

 runs along the middle; the abdomen is extremely finely 

 punctured; the apical segment is broadly rounded and, in 

 the (ƒ, provided at the end with a semi-ovate spot of an 

 extremely fine but dense punctuation intermixed with some 

 larger punctures and covered with a short whitish pubes- 

 cence; the pubescent spot does not reach the extreme base 

 of the segment. The legs are finely and sparingly punc- 

 tate, more strongly however on the apex of the femora. 



cf. Anterior tibiae irregularly curved, constricted on the 

 outer margin a little before the apex ; inner margin slightly 

 dilated towards the apex, the dilatation suddenly ending 

 at some distance from the apex thus forming a small acute 

 tooth ; intermediate tibiae slightly curved, constricted on 

 the outer margin a little before the apex ; posterior tibiae 

 longer than in the 9' slightly waved, the apex provided 

 on the inside with a tuft of long hairs. 



Q. Anterior tibiae faintly curved, intermediate and posterior 

 tibiae straight.
