 (Prog. Agr. et Vit. (Ed. VEst-Centre), 33 (1912), No. 33, pp. 203-206) .—This 

 plant bug is commonly the source of injury in vineyards, where it attacks the 

 leaves, the leaf stalks, and the young branches, causing rapid withering of the 

 lower leaves, very shortly followed by that of the entire upper part of the

The chinch bug and its control, L. Haseman (Missouri Sta. Circ. 62, pp. 

 211-214).— A brief account of the chinch bug with a summary of the means to

A parasite of the chinch bug egg, J. W. McColloch (Science, n. ser., S8 

 (1913), No. 976, pp. 367, 368).— A proctotrypid parasite apparently belonging to 

 a new genus near Telenomus has been reared by the author from the eggs of the 

 chinch bug. " The parasite has been found in every wheat and corn field exam- 

 ined around Manhattan. Of 3,101 eggs collected between April 28 and June 10, 

 the average percentage of parasitism was 20.8, and of 116 eggs collected at 

 Crawford (central Kansas) the percentage of parasitism was 16.3. The insect 

 has also been taken at Dodge City (southwestern Kansas)."

The Florida fern caterpillar (Eriopus floridensis), F. H. Chittenden (U. 8. 

 Dept. Agr., Bur. Ent. Bui. 125, pp. 11, fig. ^).— This insect has made Its appear- 

 ance within recent years in northern greenhouses, notably in the District of 

 Columbia, in Illinois, and in Ohio, and has become a source of injury. It is 

 apparently restricted to ferns, which appear to be its natural food plant in the 

 South, and has undoubtedly been introduced into northern greenhouses in ferns 

 from Florida. "It is a comparatively large and conspicuous species of cater- 

 pillar and, though not closely related to the true cutworms, has the same habit 

 as cutworms of cutting or severing portions of the fern plants, apparently 

 destroying more than it requires for food,"
