This species does not, as stated by Walker, agree " in 

 structure" with his D. tecta, which, as already mentioned, 

 belongs to my genus Nevisanus. The shape of the head is 

 totally different'^ and locates it rightly in the genus Dalpada.

 By G. Lewis, F.L.S. 



The curious insect to which this note refers was not submitted 

 to Dr. Sharp while he was writing his second memoir on the 

 ISta])hylinida2 of Jajian in 1889, for by an error in grouping it 

 was set aside as belonging to the Silphida3; and it was only 

 on my coming to write a description of it as such that I 

 discovered my mistake. I then sent an example to Dr. Sharp, 

 who kindly returned it to me with this memorandum : — " You 

 may say in your description that it is the only species in the 

 Staphylinidai yet known in which the elytra are entire, not 

 truncate, and completely cover the abdomen. In Trigono- 

 deamus and Lathrtmaum the wing-cases are truncate and 

 leave the tip of the body exposed. It has a pair of ocelli, 

 which brings it into the Omaliidee."
