NOTES ON THE BUTTERFLIES 27. GONOPTERYX MAERULA (Fabr). This is a very powerful and rapid flyer. Wet sand and the margins of mud puddles have a great attraction for it. Here these insects may be seen sometimes in swarms settled down to their feast in company with many other species. At Salt Creek in the Belize District I once saw a cloud of these butterflies in the month of August. Countless numbers of them were flying in the direction of the prevailing wind, which was from the north-east. They were all flying steadily with no inclination to settle. The butterfly is generally distributed and even common, and is most abundant in the months of June, July and August. 28. GONOPTERYX CLORINDE (Godart). This is much less frequently seen than the preceding. Its habit of settling to drink at moist places is similar to that of G. maerula and, like it, its flight is rapid and strong. It is found sparingly through the Colony but appears to be most in evidence in the Corozal District. This butterfly and the preceding are robust and compactly made, very much after the model of the female Brimstone butterfly of England. 29. KRICOGONIA LYSIDE (Godart). This is a very uncommon insect and I have met
