SCARLET LEAF=HOPPER OF PINE 

 Empoasca coccinea (Fitch)* 



In the very brief description given by Fitch which reads 

 "Scarlet Empoa, E. coccinea. Scarlet red, immaculate, pectus and 

 venter orange, elytra brownish-pellucid. Length 0.10. Taken on 

 pines No. 829, male." there is no mention of economic importance 

 nor hint as to the abundance of the species. Since Fitch's time 

 it would seem that the species has been very rarely taken so that 

 it is a matter of some interest to find the species occurring in 

 great numbers on white pines in the Cranberry Lake region. As 

 both adults and nymphs have been secured from this host plant 

 and nymphs from no other it is safe to conclude that it has close 

 restriction to the white pine or at most may occur on closely re- 

 lated species. Collections of the adults were made by Drake in 

 1917 and during the present season we have taken them in large 

 numbers both by beating and sweeping, especially in late July, 

 at which time the nymphs were noted in greatest numbers. 



The nymphs which were mainly in the last instar have the 

 general appearance of the Empoasca nymphs are dark green in 

 color closely resembling the pine leaves in tint and have a length 

 of 2.75 mm. to 3 mm. The head is short, broad, subtruncate in 

 fi-ont, the vertex depressed with two oblique furrows forming a 



* The species is included in Gillette's monograph under the genua 

 Typhlocyha and he copies Fitch's description and states that he had not 

 seen specimens and did not know of a determined specimen in existence.
