Tlie well trained exhibitor no doubt made his selection of new additions for exhibition purposes at the tall shows and by this time has his plants well under way. The beginner should send a list of his requirements to the chrys- aiitheraum specialists and let them recom- mend and till up his wants. O. W. Johnson. Two Enemies of Black Aphis. Within the last few days we notice the lace-winged fly (Crysopa oculata) has put in its appearance for the sea- son This little Insect is a foe to the aphis, being exceedingly greedy and ex- ceptionally active in its search for food. In the larval state it will be seen trav- ersing the young shoots and leaves where the aphides are usually most abundant. When within reach it seizes its prey with the two horny, jaw-like appendages to hold it secure and then thrusts its proboscis, or bill, into the aphis' body extracting the juice the same as the mosquito operates on the blood of animals. As soon as this oper- ation is completed the lifeless shell is released and the larva proceeds to the next victim. The fly which, in the mature state, is a peculiar shade of light green, ap- proaching opalescent tints, entirely ex- cept its golden eyes. It is about one inch in length aud its large wings are reticulated with a network of ribs to strengthen the thin and transparent tissues.
