No. 34-] HEMIPTERA OF CONNECTICUT I MIRIDAE. 481 



Promised Land, Long Island, N, Y. Male, 10 Aug., 1899, Hyannis Port, 

 Mass. (J. L. Zabriskie). 



Subfamily Deraeocorinae. 

 Key to Genera. 



1. Antennae linear, very long and of nearly equal thickness through- 



out; vertex transversely striate and longitudinally sulcate; seg- 

 ment ii of hind tarsi much shorter than i or iii; usually large 



elongate species (p. 481 ) Eustictus 



Antennae not so long or linear, segment ii slender at base and 

 slightly enlarged toward apex; vertex usually polished; segment 

 ii of hind tarsi equally long as i or iii, or nearly so 2 



2. Head strongly produced and nearly horizontal, facial angle acute, 



tylus projecting beyond apex of first antennal segment; dorsum 

 thickly covered with stiff erect pubescence; embolar margin thin 



and broadly expanded, sides nearly parallel 



(p. 484) Eurychilopterella 

 Head less produced, scarcely surpassing middle of first antennal 

 segment, facial angle either a right angle or only slightly less ; 

 dorsum either pubescent or practically glabrous ; embolium not 

 as the above (p. 484) Deraeocoris 



Eustictus Reuter. 



Key to Species. 



1. Hind tibiae with long pilose hairs on basal half, distinctly longer 



than true spines 2 



Hind tibiae with minute pubescence only, ptibescent hairs not attain- 

 ing length of true spines 3 



2. Pronotal disk uniformly brownish black; legs chiefly reddish, 



tibiae not distinctly banded with paler; length 8-1 1 mm grossus 



Pronotal disk blackish but paler near basal margin; legs pale tes- 

 taceous and marked with black, tibiae distinctly marked with four 

 alternating pale and fuscous bands venatorius 



3. Pronotal disk with median portion black, lateral margins broadly 



pale except for dark punctures ; male, width of vertex equal to 

 little more than thickness of antennal segment i; length, male, 



6.9 mm., female, 7.4 mm salicicola n. sp. 



Pronotal disk chiefly brownish black, not paler on lateral mar- 

 gins ; male, width of vertex equal to twice thickness of antennal 

 segment i; length, male, 5.5-6 mm., female, 7mm. ..necopinus n. sp. 



(a) Pronotal disk blackish but with paler maculae; female 



antennal segment i, in length, equal to twice the width of 

 vertex variety necopinus typical 



(b) Pronotal disk uniformly brownish black; female antennal 



segment i, in length, not equal to twice the width of vertex 



variety discretus n. var. 

 E. necopinus Knight, new species. 



Male: Length 5.6 mm.; allied to venatorius but smaller, width 

 of vertex equal to twice thickness of antennal segment i, pronotum 

 not distinctly paler on basal half, pubescent hairs on hind tibiae 

 not attaining length of true spines. 



Head: Width .98mm., vertex .28mm.; eyes less prominent 

 than in either venatorius or catulus, scarcely raised above level of 

 vertex ; height of eye .61 mm.
