108 MAINE AGRICULTURAL EXPERIMENT STATION. I915. 



numerous flecks of brown or black. The males are dark colored, or gray 

 with a rather conspicuous yellowish band across the pronotum. They are 

 somewhat smaller than the females and the angle of the head usually 

 slightly more acute. The length of the female is about 6 mm, of the male 

 5mm 



Adults of this species are common during August and September and 

 since well developed nymphs were quite plentiful in August It would 

 appear that there -was a Sipring deposition of eggs and that the nymphs 

 developed during mid-summer, reaching maturity by August and the bulk 

 of the individuals becoming mature the first of September. Whether 

 they hibernate as adults or deposit eggs in autumn has not been deter- 

 mined. 



The species is generally distributed over the state occurring where- 

 ever collections were made and it has been noted for New York so that 

 it may be considered as occupying a considerable range of the northern 

 part of the country. It is apparently identical with the European form 

 but whether a recent introduction or simply a survival of the common 

 distribution for northern countries of Europe and America dating back 

 to an earlier geological period it seems impossible to say. 



Apparently the most available treatment for this species would lie in 

 the application of the hopper-dozer method, although if eggs are depos- 

 ited in the stems of grass or other plants, where burning would be 

 possible, the utilization of the burning method in late fall or early spring 

 would probably give the best results. Rotation of crops would seem of 

 little avail as the species has evidently a wide range of food plants and is 

 doubtless able to fly readily from- field to field in search of suitable 

 food plants. A further study of the species to determine more exactly 

 its mode of hibernation and the number of generations is desirable. 



The results of life history studies on this species during the summer 

 of 1914 will appear in a later bulletin. 



Acocephalus albifrons Linn. 

 Jassus mixtus Say. Van D. Catalogue, p. 288. 



This is a dark species with the front light gray or whitish, the males 

 with brown elytra often interrupted with whitish or semi-transparent 

 spots. 



Occurs in considerable abundance at a number of localities. Females 

 were taken abundantly at Highmoor Farm in a lawn, but appeared only 

 where there was some admixture of timothy, and did not appear where 

 this grass was absent.

Found abundantly in timothy meadows in summer work of 1914 and 

 a study of its habits will appear in the bulletin on life histories.
