LEAFHOPPERS OF MAINE. I5I 



Evidently this species is quite rare or else closely confined to one 

 food plant. Our only record is from two specimens taken from witch 

 hazel at Orono, Aug. 13th. I refer it to this species though these speci- 

 mens lack an}^ red marking or smoky discoloration mentioned by Gillette 

 but in other respects they agree closely and unless it be found that 

 these features- are constant it can not be separated. I am not aware 

 that the food plant has been recorded hitherto, and no observations 

 have been made on its life history. The species has evidently little 

 economic interest. 



Dicrancura fieberi Low. 



The occurrence of this species in cultivated grasses makes it one of 

 the species to be recognized as of economic importance although so 

 far it has been observed only in small numbers in Maine. 



It is a small slender species about 3.5 millimeters long, of a light 

 yellow color with no conspicuous markings, but some specimens show 

 a distinct orange tinge on the front of the head. 



It has been taken at Orono in timothy meadow not abundantly, but 

 along with other species it must add its share to the drain upon the 

 hay crop. 



The species has a wide range throughout Europe and North America 

 whether of recent introduction or not cannot be stated and in some 

 localities it has been observed in such abundance as to have a distinct 

 economic importance. Adults occur in mid-summer, Aug. ist at Orono,. 

 and it is certain that nymphs develop earlier in the season but no exact 

 data on time of appearance or number of generations here have been 

 secured. 



Dicraneura carneola Stal. 



Typhlocyba carneola Stal. Stett. Ent. Zeit. XIX, p. 196 (1858). 

 Dicraneura carneola Gillette. Proc. U. S. Nat'l Mus. XX, 722. 



Light yellow the head produced, vertex roundingly angled before, 

 without markings but there is frequently a suffusion of rosy color on 

 head, thorax and elytra, differs from fieberi in less produced head and 

 presence of dark markings on abdomen. Length 3.30 mm. 



The basis of separation between this species and fieberi seems slight 

 espedally as with the Maine specimens it is possible to find many cases 

 where the black markings of the abdomen are more or less developed 

 and with no other positive character one may be at a loss to distinguish 

 them. 



Highmoor Farm Aug. 16, Portland Aug. 15, Orono Aug. i, 1913. 



Carneola has been a quite abundant and injurious species in the 

 western part of the country and as it occurs on grasses, oats, wheat, 

 etc., it deserves a more careful study to determine its abundance and 

 distribution in the state the extent of its attack upon different cultivated 

 crops and such facts as to its early stages as may suggest measures of 

 control.
