TPIE CANADIAN ENTOMOLOGIST. 93 



7th longest, brown ; eyes red ; honey tubes very long, reaching consider- 

 ably beyond abdomen, slightly thickened at base, infuscated at tip ; style 

 short, conical, greenish ; coxae shining and yellowish, feet black. 



^. Length .05 inch. Black. Beak reaching to middle coxae, apical 

 half black ; antennae black, hardly reaching to middle of abdomen ; honey 

 tubes rather short, black ; all coxae black, anterior and middle legs pale 

 greenish, tips of tibiae and feet black, posterior pair, excepting apical half 

 of femora, which is greenish, brown. 



Only two males were secured out of hundreds of apterous individuals, 

 and these are remarkable for being so much smaller than the females. 



Found feeding on the Pepper Vine, So/am/m jasminoides. 



THE HOP-VINE BORER. 



BY CHARLES R. DODGE, WASHINGTON, D. C. 



The casual reader, calling to mind only the half dozen hop-vines 

 usually seen about the kitchen garden, or trailing upon some farm out- 

 building, can hardly realize the possible losses to hop growers by insects. 

 According to the last census (for 1879) New York State alone had over 

 39,000 acres in hop yards, producing nearly 22 millions of pounds of 

 hops, which, at an average of 28c. per lb., would aggregate a value of over 

 six million dollars. Bearing these figures in mind, with an annual loss of 

 ID per cent, from only one insect — the hop borer — (and 25 to 50 per 

 cent, of injury has been reported) a loss of $600,000 would result in this 

 single State. 



With such a destructive agent in the hop field, is it not a little singular 

 that there is Httle or nothing " in the books " on the subject, and that the 

 pest is in all probability an unknown and undescribed species ? I am not 

 able to give its name — Prof Comstock writes me he is working it up — but 

 as I have accumulated a mass of interesting data on the subject in my 

 census work, I deem it proper to make known now the experience of 

 intelligent growers in different sections of the country, for the benefit of 

 those who have not yet learned how to fight the pest, leaving the scientific 

 name and details of habits and natural history to be supplied hereafter. 



The only mention that I can find of an insect boring into the crown 

 of the hop plant, in the manner set forth by my numerous correspondents,
