NEW JASSID^E FROM THE ROCKY MOUNTAIN AND 



PACIFIC REGION. 



BY E. D. BALL, FORT COLLINS, COLO. 



The following species, with a few exceptions, were taken by Mr. 

 E. P. Van Duzee and the author while on a very interesting and success- 

 ful trip through southern and western Colorado during the latter part of 

 July, 1900. These species are all strictly south-western in distribution as 

 far as known, and most of them were found feeding on one or another of 

 the peculiar plants of that region. While collecting in the valley of the 

 Grand River, a number of species of Homoptera were taken, hitherto 

 only known from the Californian region, and it is very probable that in 

 turn several of these species, which were taken along with them, will, 

 eventually, be found in California. 



Hecalus bracteatus, n. sp. 



Resembling brnnnens, the elytra shorter in the female, longer in the 

 male. Head longer and thinner. Female, pale yellow. Male, milk- 

 white with fuscous lines. Length, $ 7 mm., $ 5 mm. Width, 5 1.5 

 mm., o* T - 2 5 mm. 



Female. — Vertex long, with a foliaceous margin, disc transversely 

 convex, the lateral margins but slightly narrowed for half the length, then 

 forming a parabolic curve. Length and width in front of eyes about 

 equahtwoand'one-fourth times the lengthof the pronotum. Elytra brachyp- 

 terous, covering the first abdominal segment, as long as the vertex, their 

 apices rounding. Venation reduced, a broad margin outside of the first 

 section, which is once forked, no apical and rarely more than one ante- 

 apical cell present. 



Male. — Vertex roundingly triangular, its basal width one-third 

 greater than its length, slightly longer than pronotum, margin not foli- 

 aceous. Elytra long and narrow, much longer than abdomen, venation 

 distinct, somewhat irregular, usually the second cross nervure present, 

 forming three anteapical cells, of which the second is much the longer. 



Colour : female pale yellow or straw colour, the elytra with a few 

 fuscous dots next the nervures ; abdomen with a pair of olive stripes on 

 each side, these stripes margined with dotted fuscous lines, a similar 

 median line. Sometimes the olive stripes disappear, leaving the abdo- 

 men with nine dotted fuscous lines. Male milky white, sometimes with 

 five olive stripes, dotted with fuscous, on vertex and pronotum. Elytra
