CALUSINA INTEGRICOLLIS. 203 



rest black (the 2 last joints wanting) ; thorax subcylindrical , 

 a little broader than long , lateral margin very slightly 

 sinuate at the middle ; surface remotely and finely punc- 

 tured at the disk, the sides more closely and strongly 

 punctured; a deep transverse narrow groove extends im- 

 mediately behind the anterior margin across the disk ; scu- 

 tellum elongate, semi-triangular; elytra finely punctate- 

 striate , the shoulders prominent , immediately within the 

 latter and below the base a deep depression is seen, on 

 account of which the basal portion seems strongly raised- 

 a very distinct tubercle is placed immediately below the 

 shoulder, extending in shape of a short costa to the sides ; 

 inner side of the femora stained with fulvous , armed with 

 a minute tooth. 



The single specimen before me does not differ in struc- 

 tural characters from the other 2 species of this genus , 

 except in the entire , not dentate , sides of the thorax and 

 in the more cylindrical shape of the latter. 



Aoria nigripes , Baly. 



This insect, of which a single specimen was obtained 

 by Dr. Hagen , has not been previously recorded from the 

 Eastern Archipelago, Mr. Baly's specimens having been 

 captured at Hongkong; these specimens do not differ from 

 the Sumatran form. 



Rhyparida pinguis, Baly.

I do not think that the two species described under the 

 above names are specifically distinct, as fulvous and pi- 

 ceous coloured specimens from the same locality are contai- 

 ned in the present collection which I am not able to se- 

 parate otherwise. The elytra in this species are longitu- 

 dinally sulcate throughout, by which character the insect 

 may be principally known, but the margin of the thoracic 

 episternum is not concave (characteristic of Rhyparida) but
