FRED. C. BOWDITCH. 19 



Chlainys hanoiensis nov. sp. Quadrate cuneate, bronzed, 

 labrum, antennae, except apex, legs partially, two small spots on the 

 rear edge of the head and a large spot on the front of the thorax, lute- 

 ous, thorax very closely punctate (except sparser and finer on the lute- 

 ous spot), strongly gibbose in the middle and faintly tuberous at the 

 side ; elytra deeply punctate, the punctures arranged obsolutely in 

 rows on the disk, pygidium tricarinate ; presternum abruptly nar- 

 rowed aud compressed in its rear half; length 3f mm. 



Type. — 9; Hanoi, Tonkin; one specimen. 



Head nearly flat, rugosely punctate, antennae with 2d joint 

 obconic and pointed within, 3d and 4th small cylindrical, re- 

 mainder transverse, thorax with a strong gibbosity which is 

 almost perpendicular in front, moderate behind, well marked 

 about the base by the side sulcus, which shows as a smooth 

 crease at the rear sides, the sides of the median sulcus begin 

 as an obtuse ridge behind and rise to a small tubercle : then 

 the depression becomes evident and well marked, and con- 

 tinues until it impinges upon the yellow spot in front ; at the 

 apex the side ridge forks and sends a small ridge to either 

 side, which small ridge forms the tip of the side elevation, 

 the lateral tubercle is obvious but not strong, the elytra show 

 no scutellar ridge, only two minute tubercles. There are 

 two good sized tubercles along the suture, the first median, 

 the second apical and costiform ; these are connected by a 

 low smooth ridge, the antehumeral ridge is shown as a similar 

 smooth line, connecting the tubercles, one basal, the second 

 behind the shoulder, the others broken in the apical region. 

 There are also broken remains of a subhumeral ridge end- 

 ing in a well marked apical tubercle, the smooth connecting 

 line shows best looked at sideway on the disk, median carina 

 of the pygidium fine and sharp, abdominal side tubercle 

 almost absent. 



Chlainys yvmnana nov. sp. Oblong quadrate, almost parallel, 

 bronzed, slightly shining above, below with a faint blackish tint, an- 

 tenna, except apex, labrum and tarsi, flavous; thorax with median 

 sulcus almost entire, two divergent carinae on either side ; a strong 

 lateral tubercle ; elytra with the usual lines much broken into frag- 

 ments and tubercles ; pygidium tricarinate, the lateral carinae obsolete 

 at the lower ends; presternum with sides parallel in anterior third,
