NOTES ON THE INSECTS OF ANTIGUA 
By Dayton Stoner 
The island of Antigua is not under so high a state of cultiva- 
tion as is Barbados; neither is it so thickly populated as that 
island; consequently natural enemies of insects are not numer- 
ous. All these conditions make for a greater and more varied 
insect fauna than we found at Barbados. | 
The low grassy lands towards the center of the island fur- 
nished a great variety of insects, particularly in Hemiptera 
and Orthoptera, and collecting with a sweepnet was very pro- 
ductive of results here. 
There are few freshwater streams and ponds on Antigua. 
However, one of these ponds situated about three-fourths of a 
mile northwest of the dockyard at English Harbor was made 
the object of a rather intensive study. Among the more inter- 
esting forms of imsect life found here was the mole-cricket 
(Gryllotalpa sp.) which we had not discovered at Barbados. 
This insect lives mostly under ground, constructing tunnels a 
few inches below the surface and feeding upon the roots of 
various plants which happen to be in its path. The mud shores 
of this little pond were literally undermined in some places by 
the tunnels of these peculiar insects. Other groups represented 
in the pond were water-striders, water-boatmen, (the latter the 
most abundant of the larger insects) backswimmers, several 
species of water beetles including both larve and adults, dragon- 
fly and damsel-fiy larve and adults, various species of dipterous 
larve—in fact the place was found to be a veritable storehouse 
of entomological material. Of course such ponds offer excellent 
breeding places for mosquitoes and we found great numbers of 
both larve and pupe. 
At the south end of the island where most of our collecting 
was done, many localities are heavily wooded. Small cultivated 
and semi-cultivated places on both high and low lands offered 
excellent collecting grounds. In many places highly xerophytie
