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



St. Vincent: (Cameron, 1913; Leng and Mutchler, 1917; British Museum; Cam- 

 eron collection).

/Specimens examined. — I have seen 12 examples (including the 

 type) in the British Museum and 7 in Dr. Cameron's collection. One 

 of the former was borrowed for further study. 



Remarks. — Distinguished from agnatus^ besides the characters men- 

 tioned in the key, by the seventh sternite. The above description
