 denticles; gular sutures moderately close, most approximate along

 out distinct ground sculpture. Pronotum as wide as head, nearly one- 

 fifth wider than long, sides feebly converging and evenly rounded into 

 base; punctation very similar to that of head; without a smooth mid-

Types locality. — Colombia. 



Types. — Either in the Hope Museum, Oxford, or Zoologische Mu- 

 seum, Berlin. 



Records. — The following are the records known to me : 



St. Lucia: (Blackwelder station 220D). 



fc>t. Vincent: (British Museum). 



Grenada: (Cameron collection; British Museum; United States National 



Museum). 

 South America: Colombia (Erichson, 1840; Bernhauer and Schubert, 1912). 



Specimens examined. — I have seen 158 examples in the British Mu- 

 seum, 6 in the collection of Dr. Cameron, and 1 collected by me in 

 April 1936. (These are all from the West Indies.) 



Remarks. — This species also is known to me only from the West 

 Indies but seems to be properly associated with the Erichson name. 

 It is distinguished by its smooth shining integuments and channeled 

 pronotum. It belongs in the subgeims Sunius s. str. 



My specimen was found in rotting cocoa pods,
