tergite quadriclentate, the middle teeth longer and narrower. Fe- 

 male^ eighth tergite with four slender processes, the middle pair 

 longer. Length, li/^ to 2 mm. 



Type locality. — Puerto Rico. 



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

 Museum, Berlin, 



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



Jamaica: Moneague (Blackwelder station 370), Porus (Blackwelder station 423). 

 Puerto Rico: (Erichson, 1839b; Wolcott, 1924, 1936), Adjuntas (Blackwelder 



station 48C). 

 St. Lucia: (Blackwelder stations 220E, 224, 226, 227). 

 Grenada: (Blackwelder station 153A). 



Specimens examined. — I have seen 5 examples in the British Mu- 

 seum and 18 collected by me during 1935-37. 



Remarks. — This species is very similar to pulchellus but apparently 

 can be distinguished by the smaller size of the pale areas as well 

 as by the male characters. Both these species vary somewhat in the 

 former character and might be considered to be a single species ex- 

 cept for the distinct difference in shape of the enxargination of the 

 eighth sternite. This description was drawn fi'om an example from 

 St. Lucia. 



My specimens were found in rotting cocoa pods, under-chips on 

 fresh stumps, in dung, and under bark.
