LIFE HISTORIES OF LEAFHOPPERS OF MAINE. 



Fig. 7. a, Draeculacephala angnlifera, last instar nymph ; b, Phlepsius 

 apertus last iristar nymp'h. (Original). 



Phlepsius apertus Van D. 



The larva referred to this species is quite broad, flattened and 

 with a rather strongly produced vertex. The color is light 

 clay to whitish and there are two broad stripes on the vertex 

 about equally wide on the prothorax, narrower on the meta- 

 thorax and extended as narrow lines on the abdomen to the 

 terminal segment. They are lighter than the vertex, black on 

 the meso- and meta-thorax and abdomen. A broad marginal 

 stripe covers the sides of the thorax and the narrower stripe 

 and lateral border extend from base to tip of abdomen. Length 

 5 mm. 



Two specimens of this have been secured, one of them Au- 

 gust 8th in timothy meadow and from its characteristics it is 

 referred somewhat doubtfully to the above species, although 

 it was not possible to rear specimens to the adult stage. 



Balclutha punctata Thunberg 



This species is very widely distributed and was mentioned in 

 a previous Bulletin as one of the common forms. It has be?n 

 taken especially upon Canadian blue grass and during August 

 was found in all stages and while the life cycle has not been 

 followed in complete detail it would be useful to furnish de- 

 scription and figures of the stages observed.
