examined near the exterior margin, while others show indication of 

 more or less striation near the sutures, as shown in figure 3 a. The 

 species differs from others of the same genus in having the fifth joint 

 of the antenna nearly one-third shorter than the fourth, and usually 

 just perceptibly shorter than the sixth/' To facilitate further recog- 

 nition of the particular form under discussion, it should be said that 

 the elytra are very finely and densely punctured, and pubescence is 

 scarcel}^ evident save at the apices. The head is more coarsely punc- 

 tate, and the thorax still more deeply and roughly punctured. 



REMEDIES. 



Unless remedial measures are instituted, there is probability of this 

 species becoming an important enemy of sugar-beet culture in the 

 United States. Paris green or arsenate of lead applied in the form of 

 a spray is all that is necessary to destroy it, and where irrigation can 

 be practiced this enables the plants to recuperate from moderate 

 attack. 



SOME INSECTS RECENTLY INJURIOUS TO TRUCK CROPS. 



By F. H. Chittenden, Washington, D. C. 



The fall army worm [Lapliygma fTugiperda S. & A.). — Septem- 

 ber 8, 1902, Mr. L. Donner, Seabrook, S. C, sent a series of this 

 species in diflerent stages of larval growth, with report that some 

 time earlier it had done considerable damage, and had virtually stripped 

 asparagus plants of their foliage and eaten the skin off the stalks. 

 His asparagus plants had been sprayed ten times with the Bordeaux- 

 resin mixture, beginning immediately after the crop and applying the 

 spray at intervals of two weeks and after rains. But in spite of this 

 the fall army worm ate the foliage clean, and in some parts of the 

 plantation even peeled the stumps. 



White grubs {Lachnosterna sp.), — June 2, 1900, Miss Eliza A. 

 Blunt, New Russia, N. Y., stated that white grubs did great damage 

 to asparagus as well as grasses. An asparagus bed that w^as planted 

 the previous year with two-3-ear-old roots 3 feet below the surface 

 showed that the grubs worked at that depth, as not a sprout had 

 appeared during the season of writing. 



The Southern leaf-footed plant-bug {Leptoglossus phyllopus 

 Linn.). —September 8, 1902, Mr. L. Donner, Seabrook, S. C, sent 



« It should be stated at this point that the genus Monoxia is separated from Galeru- 

 cella, with which it was formerly united, by a sexual character, which consists in 

 the male having the claws nearly bifid; see fig. 3 $. In Galerucella both sexes 

 are as shown at 9 .
