OF BRITISH HONDURAS the hope of obtaining another specimen, but I did not succeed in this. The insect is a great rarity. 9. HELICONIUS DORIS TRANSIENTS (Stgr). A charming insect which I have captured south of Belize, but have never seen in the northern districts. It is fairly common in the Toledo District and as far as Belize. It is fond of flying rather high in the air, floating with outstretched wings and almost stationary in the still forest atmosphere. As far as this Colony is concerned the coloured rays on the under-wings are always scarlet, but I believe that in countries south of the Colony the colour of the rays is altered to a bluish green. This variety is known as H. viridis, and is the common form there, the variety with red rays being scarce or entirely absent. In the Colony, on the other hand, the variety with red rays is the only one found, but I have noticed that in some of the specimens there is a bluish margin to the red rays, more clearly defined in some examples than in others. I have only taken the insect with green rays once and that was close to Puerto Barrios in Guatemala only a few miles south of the Colony on the Atlantic Coast. Only one specimen was seen and this was flying in company with the red ones.
