THE CANADIAN ENTOMOLOGIST. 205 



Colour : vertex white, washed with yellow, a crescent either side the 

 point, a dash on the lateral margin and interrupted before the middle^ 

 brownish fuscous ; face pale yellow, a narrow black line just under the 

 margin of the vertex ; pronotum yellow, with six dark brown stripes, the 

 inner and broader pair arising behind the middle of the vertex, continuing 

 across the scutellum ; elytra yellow, with five light brown stripes on each 

 side, interrupted by the light nervures, the reflexed veinlets broadly white, 

 lined anteriorly with fuscous ; below pale yellow. 



Genitalia : ultimate ventral segment of the female half longer than 

 the penultimate, the posterior margin angularly excavated one-third its 

 depth, margins of the excavation near the centre slightly toothed and 

 marked with black. 



Described from three females ; two taken from the Platte valley at 

 Sneyder and Julesburg, Colo., and one from Kimball, Neb. This is a 

 very distinct species, and though unquestionably a member of the reflex- 

 veined Deltocephalids, still in face characters it recalls a Platytnetopius, 

 and in colour and ornamentation it might easily be confused with Athy- 

 sanus colon or texanus. 



A NEW SPECIES OF KERMES.

Kermes trinotatus, n. sp. — Female scale variable in size, averaging 

 about 5;^ mm. long, 6 mm. wide, and 4^ mm. high; rounded above,

 is present it is crossed with more or less dark lines showing segmentation. 

 There is a rounded dark spot on each side of the front, and an elongated 

 dark blotch extending for a short distance above and below the anal 

 opening : hence the specific appellation. 



Larvae 416 \i long by half as broad; caudal setae 160 /x long; 

 antennae 100 /x long, 6 jointed, formula (1,2) (3, 4) (5) (6), 6 longest, 3 and
