hind basitarsi large and hair>-, middle ones small; knob of halteres- 

 dark brown. The second anal vein, differently from the fossil, is 

 abruptK' deflected downward at the basal corner of the anal lobe. 

 In Bezzi's kc\' of South Ainerican Rhamphomyia (1909) this falls 

 nearest to R. limbipennis Bezzi. Above timber-line, in the Arctic- 

 Alpine zone, Baldy Mtn., Boulder County, Colorado, July 24, 1915.

I take occasion to correct two misprints in former papers on 

 Diptcra. In Can. FInt., 1915, p. 316, read Chironomus guate- 

 maltecus; and p. 351, in fourth line of description, read gre\ish 

 instead of greenish. 



NEW SPECIES OE ECTETTIX AND PHLEPSIUS 



(HOMOPTERA).

The genus Eutettix is one of the most interesting of the groups 

 of leaf-hoppers in the diversity of food plants of the different 

 species, and at the same time in the constancy with which a given 

 species is confined to its host. 



At the time the writer published the review of this genus 

 little was known of the life-histories or food plants of a number 

 of western species of the strohi group. Erom circumstantial evi- 

 dence it was thought that saucia would probably be found to 

 occur on Eriogonum. Since that time this species has been found 

 in some numbers on a species of this plant in California. The- 

 type specimens of columhiana described below were taken from 



April. 191(i
