caused the death of so stout and thick-leaved a plant, yet 

 here were hundreds of the culprits in all stages of growth 

 plying their jaws before our eyes in proof. 



This insect, which occurred in both sexes and in all 

 stages of growth from larvae of minute size proved to be 

 the wheat thrips (Limothrips tritici) of Fitch who gives 

 an account of its appearance and habits in his " Second 

 Report on the Noxious Insects of New York," p. 304. 



Through the kindness of C. L. 

 Flint, Esq., of the Mass. State 

 Board of Agriculture, we are en- 

 abled to present figures of these 

 insects taken from Dr. Packard's 

 Report to the Board as State En- 

 tomologist. The females alone 

 are winged, the males being J} 

 wingless and closely resembling 

 the larvae. The body of the 

 female (Fig. 1) is smooth and 



shining, uniformly greenish yel- 



a, 



low with no other markings ; the 



legs are a little paler towards ar- ^ arva&ndm&}eof Limo(hripstritici 



ticulations. The larva 



(Fig. 2, b) is entirely 



greenish-yellow, the 



head and prothorax of End of antennae of male - 



the same color as the rest of the body. The male (Fig. 



2, a) differs from the larva in having 2-jointed feet (tarsi) 



and 7-jointed antennae, those of the larva being 4-jointed. 



The small line at the side of each figure indicates the 



natural size of the insect.
