towards the apex. The Hagellum is covered with 
longish, stiff hairs, directed towards the apex. Head 
broad, rather large; eyes large, converging above; 
ocelli in a wide triangle, widely separated, the two 
upper nearlytouching the eyes; occiput concave. Face 
deeply excavated, the excavation reaching laterally 
to the mouth ; epistoma projecting, broadly keeled. 
Thorax large, broad, without sutures ; scutellum 
large ; metathorax small. Abdomen shorter than the 
thorax, the apex narrowed, transverse. Wings scarcely 
so long as the body ; cubitus more than double the 
length of ulna, which is very short ; radius absent ; 
edge of wing shortly ciliated. The cubitus does not 
reach to the middle of the wing. Hind tibise almost 
one-spured, the inner being a mere stump. 
The above-described species is certainly not an Encyrtus 
as now understood. I cannot make it fit into any of 
the genera as defined by Mayr and Foerster; but 
having only a single example (a male) I do not care 
to found a new genus for its reception. The sculpture 
of the head and thorax is pretty mucli as in Bothrio- 
thorax. 
Taken on several of the islands. 
Ohs. — -Mr. Blackburn (antea, p. 139) states that he has 
taken in the Archipelago over one hundred species of 
Hymenoptera \ but I am only acquainted with 83 
(or, 84 with Apis mellifica). I believe there are two 
or three undescribed species in the British Museum 
which were sent by Mr. Blackburn some years ago.

“ The humming of the Snipe,” by Dr. A. Hodgkinson. 
The cause of the “ humming or “ drumming ” sound 
produced by the common snipe during the breeding season 
has long been an open question amongst naturalists. 
Bechstein attributed it to the beak; Naumann, Saxby, 
Hancock, and others believe it to be produced by the wings
