S56 i)r. David Sharp on some 



at Kandy, 18th February, 1882. It is abundantly dis- 

 tinct from E. hullatus, Shp. 



Protosteenum, gen. nov. 



Corpus oblongo-ovale, subdepressum. Prosterniiin, mesosternum 

 et abdominis segmentum basale carinata. Tarsi perbreves, pos- 

 teriores articulis tribus basalibus lougitudine subaequalibus. 



This genus is established for a single species — a very minute 

 insect — having the form of the species of Dactylosternum, but 

 differing therefrom by the mesosternum possessing merely a 

 slightly elevated carina along the middle. By this character, and 

 by its general facies, it approaches the Central American genua 

 Heteryon, but in that genus the first ventral segment is not 

 carinate. The palpi are quite short, the antennae have a very 

 elongate club ; the mentum is deeply and broadly impressed on the 

 middle in front ; the carina on the presternum is very minute ; the 

 mesosternal carina is fine and is divided into two parts, the anterior 

 of v^'hich emits a small branch on either side ; the metasternum is 

 also feebly carinate in its anterior part. The carina on the first 

 ventral segment is fine but very definite and elongate. The whole 

 of the under surface is covered by a minute sculpture making it 

 quite dull. 



Protosternum atomarium, sp.nov. 



Rufo-piceum, subdepressum, oblongo-ovale ; antennis palpisque 

 flavis ; subtiliter punctatum, elytris striato-punctatis, striis postice 

 magis profundis. Long. If mm. 



Antennae with the club clear, pale yellow. Head broad and 

 short, not visibly margined, very finely punctate, eyes not visible 

 from above. Thorax very short, very little emarginate in front, 

 rather closely and finely punctate, with a large foveiform puncture 

 on each side at the base. Elytra continuous in outline with the 

 thorax, the outer margins very slightly reflexed ; with very regular 

 series of coarse punctures, which are finer and appear more like 

 stride near the suture, and with a very feeble interstitial punctua- 

 tion.
