that their colors harmonize with those of the discolored leaves 

 which thus form a protection, the insect being only recognized 

 on close observation. My assistant, Mr. C. W. Mally, has found 

 them attacking the following plants, all of which are affected in 

 the same manner : Red clover, Trifolium pratcnse L., T. rcpens 

 L. ; prickly lettuce, Lactuca scariola L. ; ragweed, Ambrosia ar 

 temisicefolia L. ; white vervain, Verbena urtictzfolia L. ; burdock, 

 Arctimu lappa L.; narrow plantain, Plantago lanccolata L. ; P. 

 rugelii Deca ; ground cherry, Physalis pubcscens L. ; seliheal. 

 Brunella vulgar is L. ; smartweed, Polygonum hypropi per aides 

 L. ; mares tail, Erigeron canadcnse L. ; thistle, Cardtius lancco- 

 latus L. ; sticktights, Bidens sp. ; low mallow, Jlfalva totundifolia 

 L. ; yellow sweet clover, Melilotiis officinalis L. ; sour grass, 

 Oxalis stricta L. Aster sp. ; crab grass, Panicum sanguinalc L. ; 

 and also on cucumber vines in the greenhouse. In all cases the 

 species feeds largely on the upper surface of the leaves, but may 

 sometimes be found on the under side, thus showing that it has 

 little fear of natural enemies when in exposed positions. 



These insects do not become abundant until early Summer, 

 and continue so until Fall, probably October, when they gradu- 

 ally disappear. In the insectary we have been able to keep a 

 single female alive until late February, but reproduction was 

 almost at a standstill until April, when we found the adults and 

 young becoming more and more abundant from that time for- 

 ward. From this it would seem that the species might hibernate 

 in the adult stage, but that it usually passed the Winter in the 

 egg; though nothing has as yet been proven, and hence no posi- 

 tive statements can be made on this point. 



In the Report of the Kansas State Agricultural College for 

 1889, two species of these insects are recorded as attacking beans, 

 being found on the under side of the leaves, well down toward 

 the ground. The species implicated in this work were Agallias- 

 tes bractatus Say and Halticus minutus Uhler MS. From the 

 figures given (PI. X) of these two species it would almost seem 

 as though they might be the two sexes of one of them. In con- 

 nection with this, it might be well to call attention to the fact that 

 in " Comptes Rendus" of the Biological Society of France, M. 

 A. Girard has called attention to the depredations of a Halictus 

 minutus on the peanut crop in French Cochin China (see " Insect 

 Life" iv, p. 340, 1892). In this latter case the peanut crop was 

 threatened with absolute destruction by reason of the attack of 

 .this Capsid.
