59 2 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



Female: Length 5.6 mm., width 2.6 mm. ; more robust than the 

 male, but very similar in coloration ; larger and more reddish than 

 omnivagus and semivittatus ; distinguished by pale stripe on sides 

 of venter and by absence of fuscous spots behind the calli, also 

 by the distinctly reddish color on hind femora and sides of body. 



Breeds on Quercus alba.

L. (Neolygus) semivittatus Knight. 



Cornell Univ. Agr. Expt. Sta., Bull. 391, 626, 1917. 



Male: Length 5.3 mm., width 2.28 mm.; resembles omnivagus 

 in coloration of the hemelytra ; two small fuscous marks on disk 

 behind calli ; very suggestive of caryae var. subfuscus but differs 

 by having a pale stripe through the fuscous on sides of venter ; 

 similar to quercalbae in having the venter fuscous brown and with 

 pale stripe dividing the dark color, but distinguished at once by 

 the fuscous marks on pronotum; genital claspers distinctive (fig. 

 124). 



Female: Length 5.4 mm., width 2.2 mm.; very similar to the 

 male in coloration but with less fuscous on the hemelytra; most 

 easily confused with caryae var. subfuscus but distinguished by the 

 longitudinal pale stripe running through the fuscous color on sides 

 of venter. 



Breeds on Quercus alba. 



Long Island, N. Y. 



*L. (Neolygus) omnivagus Knight. 



Cornell Univ. Agr. Expt. Sta., Bull. 391, 627, 1917. 



Male: Length 5.4 mm., width 2.2 mm. ; yellowish brown, corium 

 dark brownish to fuscous apically, clavus dark brownish or black- 

 ish; very much resembling forms of semivittatus and quercalbae, 

 also might be confused by coloration with caryae var. subfuscus; 

 genital claspers distinctive (fig. 125). 



Female: Length 5.4 mm., width 2.5 mm.; usually paler than 

 the male, more yellowish brown; never with reddish as in querc- 

 albae, nor with fuscous marks on the pronotum as in semivittatus 

 or in caryae var. subfuscus; very similar to canadensis but that 

 species has the apical one-third of antennal segment ii more dis- 

 tinctly black, the fuscous spot on the apex of the corium smaller 

 and not invading the pale embolium. 



Breeds on Quercus alba, Q. rubra, Q. coccinea, and probably 

 other oaks ; breeds occasionally on Cornus, Castanea, and 

 Viburnum.
