by Guilding, who is perhaps best known to zodlogists as the 
discoverer of Peripatus. These notes were on the life history 
of Ulula macleayanus Guilding,! which is synonymous with 
Ulula hyalina, or a variety of it, occurring in the island of 
St. Vincent, West Indies, where Guilding obtained his specimens. 
His description is meager and, to some extent, erroneous ; but 
the arrangement of the repagula has not been observed subse-

which contained short descriptions of sixteen species of Asca- 
laphidæ. He repeated Guilding’s descriptions and also described 
the larva of Ulula senex Burm., ignoring the fact that it was

U. macleayanus. Westwood wrote a review in 1888 of the 
previous papers on the life history of the Ascalaphidz? and 
added a short life history of a Ceylonese species, perhaps 
Ascalaphus insimulans Walk., accompanied by figures, but
