 occur Ihroui^hout the entire lengtli of Indiana. As it may beeonie a 

 serious enemy to li^rowiiiii: corn, this information has a certain practi- 

 cal \alne. In my pai)er just referred to I also ^a\'e the distribut ion 

 of Jlijochrujj.)iji(iiiaiHosus, as far as it was then possible. At that 

 time I had a rather vajruo report of its liavinj:; been found in Ken- 

 tucky, but as this was far out of its known range of distribution I 

 withheld the information until such time as I could either verify it oi- 

 be nioir preparetl to show that it was an erroi-. 1 find, howex'er, that 

 one of Dr. Forbes's assistants has taken it in Central Illinois on weetls 

 and corn, and the Kentucky locality does not now appear at all 

 doubtful. 



Some ten years ajjjo the late Mr. Bolter, of ("hica.!J^o, wrote me that 

 about twenty-five years before lie liad found the aspara.gus beetle 

 {Crio ceris aspanu/i) as far as 40 miles to the west of that city, l)ut 

 had iTFrer^trtxserved it since that time; also that Mr. B. D. Walsh had 

 given him specimens taken about Rock Island, 111. The si)ecies has 

 renuiined unknown, so far as I am able to learn, in Illinois since tliat 

 time. Last year, 1!H)2, and again this year, 1!)0;3, two of Dr. Forbes's 

 assistants have found it ([uite plentifully in some of the northwest- 

 ei-n suburbs of Chicago." During the past summer I searched care- 

 fully for it about Kock Island, but failed to find it tliere. It is cer- 

 tainly interesting that it should have continued to exist about Chicago 

 during these tliirty-five years Avithout spieading, while in Ohio and 

 Ontario its diffusion to the westward is sutliciently marked to atti-act 

 considei'able attention, ^\'ln'n this w(^stward tideof migration I'caches 

 Illinois, as now seems every way pi-obable, it will be of much impor- 

 tance to observe if it stoi)s here or continues its westward march across 

 the State, leaving the old colony about Chicago behind. 



I may add that the hai-le(iuin cabbage bug {^ful•(J(lnfifl liislriomcd) 

 is represented in the IJolter collection l)y a specimen taken about 

 Chicago, while it bred in I'rbana in ISDi;, the .same year that it pushed 

 its way north in Ohio, l)reeding on rape at Wooster and being found 

 at llinkley, about 25 miles from the south shore of Lake Erie. 



Mr. Gillette reported the presence of the harlecpiin cabbage bug in 

 Coloi-ado and said that I)i(ihrolic(i riftuhi is spreading in the Stale, a 

 few si)ecimens liaving been takiMi at Foi-t Collins. 



^Ir. I'Metcher stated that in Ontai-io (he asparagus beetles were 



" In one of the.se localities an asparagus grower stated that the species had been 

 present in that \icinity about twenty-five years before the time of writing. —
