214 THE CANADIAN ENTOMOLOGIST. 



A NEW CAPS ID. 



BY CHARLES STEVENSON, MONTREAL.* 



Lygus Chagnoni, n. sp. — This species of the genus Lygiis is of a form 

 near to L. pabulinus^ Linn., in appearance. 



It is ovate, convex, bright green in Hving specimens, with irregular 

 purplish-brown markings at the base of the membrane, smooth and 

 without bristles, and a silky pubescence on the sides of the pronotum, 

 which has an orange-yellow border next the head, shading backwards in 

 narrow lines into the green coloration, so as to make the green appear in 

 broad bands. 



Head polished and uniformly orange-yellow. Eyes large and 

 prominent, and of so dark a brown colour as to appear black. 



Antennfe slender and long, brown, with shades of orange-yellow. 

 Basal joint uniform yellow, second joint slightly thickens and becomes 

 brown towards the tip, the remaining joints dark brown, becoming much 

 darker towards the end of the last one, which is very dark. 



Scutellum convex, smooth, and of a deeper green than the wings. 

 Wings uniformly green on the corium, clavus and cuneus, the mem- 

 branes paler and somewhat transparent, with irregular purplish-brown 

 markings. At the meeting of the corium, there is a purplish-brown V. 



Abdrmen pale apple-green, with marked silvery pubescence, in the 

 form of dashes and dots at the joints, the genital pieces green, with slight 

 rusty tinge on the margins. 



Legs pale green, the coxa, trochanter, as also the mesoscutum, very 

 pale, without any spots or markings. 



Length to the end of abdomen, 4.0 mm.; to the tip of the membrane, 

 5.0 mm.; width of pronotum, 1.25 mm. 



Described from three specimens, one caught by Mr. G. Chagnon, in 

 Rouville Co., Que., iithjuly, 1902, and two by myself on Montreal 

 Island, 14th July, 1902. 



I take pleasure in naming this species after my friend, Mr. G. 

 Chagnon, as a slight token of my appreciation of his companionship in our 

 collecting trips and his great assistance in the identification of species and 

 in my entomological work generally. 



*Read before a meeting of the Montreal Branch, Ent. Soc. of Ont., 9th February, 

 1903.
