58 THE CANADIAN ENTOMOLOGIST. 



Nectarop/iora destructor, ii. sp. — i'lie general colour of bolh winged 

 and wingless individuals is green ; conforming so closely to that of the 

 pea plant itself, we might, perhaps, better call it pea-green. The colour, 

 however, varies slightly with the age of the insects ; the young when first 

 born are lighter, still bordering the greenish shade of the adult ; old or 

 spent females are lighter, some having a greenish-yellow tinge. In many 

 instances individuals in a colony will be seen of a yellowish or creamy 

 tinge. Such individuals are usually affected with a fungous disease. The 

 variation in colour may, therefore, in many instances be attributed to some 

 abnormal condition. 



The general form of the body in both winged and wingless specimens 

 is elongate and fusiform, the latter being slightly the larger. The average 

 length of the body in both forms is about 4.50 mm. Eyes are red and 

 prominent ; colour showing conspicuously in specimens mounted in 

 Canada balsam. Antennae lighter than body; tubercle prominent; 

 joints darker than rest of segment ; seventh joint quite filiform and 

 fuscous. Legs long and conspicuous ; tarsi, distal ends of tibia and 

 femora fuscous. Honey-tubes fuscous at tips, otherwise concolorous 

 with body. 



Winged Female. — Colour pea-green. Fore wing about 5 mm. from 

 tip to base and about 2 mm. wide at broadest part ; entire wing expanse 

 about II mm. Length of body, including style, generally 4 to 5 mm.; 

 some cases where the female is distended with young the length is 6 mm. 

 Width of body varies from i to 1.50 mm., depending on condition of 

 sjjecimen. Antennte long and slender, reaching to or slightly beyond 

 the tip of the style ; first and second joints short and closely joined to 

 tubercle ; other joints vary slightly ; the following measurements represent 

 the general average of a long series : IIL 1.50 mm., IV. i.oo mm., V. 0.75 

 mm., VL 0.50 mm., VII. 1.50 mm. Wings transparent^ veins slender, 

 typically represented in Fig. 4. Honey-tubes long, slender and 

 cylindrical, extending beyond the tip of the abdomen, in some cases 

 to the lip of the style ; they are usually about one-fifth the length of the 

 body, varying from i.oo mm. to 1.50 mm. Style conspicuous, about half 

 the length of honey-tubes. 



Apterous Female. — As a rule, slightly larger than the winged female. 

 Colour pea-green. IJody slightly more elongate and fusiform than 

 winged specimens; length varying from 4 to 6 mm.; width varying from 

 I to 2 mm. Antenna? reaching beyond the tip of the style ; length of
