The Scarlet Jiuiiiier Beau Thrip« is another common 

 variety, doing great damage among the runner beans, and 

 attacking the buds and blossoms in the same way as the 

 Pea Thrips do on the pea crops. The Eunner Bean Thrips 

 was described at considerable length in a number of the 

 "Journal" of the South-P^astern Agricultiu-al College, 

 and was stated to be quite distinct from the Pea Thrips. 

 " The attack is discernible at first," says the writer, " on 

 examining the blossoms; later on, still more so by the 

 complete barrenness, of the runners — a few flowers only, 

 and here and there a dwarfed pod being seen. The lower 

 petals nrst show signs of disease, becoming more and 

 more shrivelled, until they are reduced to a mere crumpled 

 masis; then the upper part of the blossom gradually dies 

 away. Sooner or later the flowers fall off from the top 

 of the flower-stalk, leaving the petioles attached to the 

 stem, looking just as if the bloom had been severed by 

 a sharp knife." The female of the Scarlet Eunner Bean 

 Thrips is about one-sixteenth inch in length, the colour 

 is almost black or dark brown, a few hairs are on the 

 joints of the body, the wings are of a dull white with three 

 rows of spines, and the legs are deep yellow-brown. The 

 larvje are of an orange colour, and the pup?e are very like 

 them, only paler in colour and with small wings. 



Eemedies. — The Thrips shelter during the winter in the 

 earth and under the bark of trees or poles, in the dried 

 grass, and other like covers. It is imperative, therefore, 

 after an attack to destroy all such winter sheltere, pea and 

 bean sticks, etc., and a different crop should be sown on 

 the ground the following year. Where spraying is em- 

 ployed, when the foliage is attacked, use Formuhi 14, or 

 one ounce of pyrethrum and one ounce of soft soap to 

 eight quarts of water. 



Pea Midgre (Cecidomyia pisi). — The larvne of this 

 small inst'ct sometimes badly infest the yoimg pods, feed- 

 ing upon the peas, and causing the pods to turn yellow.
