carina not traceable, even on the posterior extension. Antennee short, 

 first and second segments subequal, third equal to the length of the 

 other three taken together, fourth a little shorter than the first and 

 second conjoined. Spines on front of vertex arranged as in L. mutica 

 Say, the decumbent spines from back of vertex usually a little 

 shorter. Elytra with the areolse in subcostal area arranged in four rows 

 (in two or three specimens scarcely more than three), the costal area 

 with only a few distinct cells at the constriction near the apex. 



General color reddish brown, usually with blackish or fuscous areas. 

 Legs with the tarsi fuscous. Body beneath dark reddish brown. Eyes 

 black in fully matured specimens. Collar and apex of triangular por- 

 tion of pronotum sometimes paler. In some specimens a few of the 

 veinlets are infuscate. 



Length, 2.21 mm.; width, .87 mm. Length of antenna! segments; 

 1, .1 mm.; 2, .1 mm.; 3, .30 mm.; -i, .16 mm. 



Described from numerous males and females, taken on Stone 

 Mt., Georgia, June 8, 1917. The specimens were collected on 

 Hglly, Ilex sp., in company with a few specimens of L. elliptica 

 McAtee by Mr. H. H. Knight. Type (male) and allotype 

 (female). The insect is most closely related to L. mutica Say 

 from which it may be separated by its much smaller size, and 

 shorter antenna. Long series of mutica from various parts of 

 eastern United States fail to show any intermediate forms 

 between the tw^o species.
