222 MONOGRAPHTA 



a transverse line and three fuscous spots, a pitchy triangular 

 patch before each eye, and a sinuated band at the occiput ; 

 antennae prominent, the first joint short and cylindrical, 

 second smaller, third transverse, fourth very large and ovate ; 

 apex truncate, terminated by a fasciculus of hairs ; prothorax 

 sub-quadrate, with an angular protuberance on each side, 

 anterior part rotundate ; metathorax trapezoidal ; abdomen 

 ovate, depressed in centre, testaceous yellow, lateral margin 

 fuscous ; apex densely fringed with hairs ; legs long and 

 thick. Length f to 1. 



This species approaches in many respects the M. tridens 

 of Dr. Burmeister, which he says is found on the Coot 

 (Fulica atra), but as he does not allude to the prominences 

 of the prothorax, or the peculiarity of the last joint of the an- 

 tennae, I am induced to think it is a distinct species, besides 

 I have never found or received any specimens of Menopi 

 from that bird. I have found it however two or three times 

 on the Water Rail (Rallus aquaticus), and also on the 

 Little Grebe (Podiceps minor), and Mr. Thompson sent me 

 examples from the Water Gallinule (Gallinula chloropus).
