OETHOPTEEA OF INDIANA. 



171 



at base of arcuate portion. Body (average), 11 mm.; forceps, male, 

 4-8 mm.; female, 3 mm." — Scudder. 



I have not seen this earwig in Indiana, but Eehn, loc. cit., states 

 that four males, collected by F. M. Webster, at Lafayette, Indiana, 

 about May 15, 1889, are in the collection of the U. S. National Mu- 

 seum. It is an introduced species, which has before been recorded in 

 the United States from New York and New Jersey. 



II. Labia Leach (1815.) 



Size, small. Body, flattened and slender, the abdomen slightly 

 widened in the middle. Antenna3 about half as long as the body, 10 

 to IS-jointed, the joints moniliform, or of equal size throughout, 

 obconic, about three times as long as broad. Both tegmina and 

 wings present in our species. First and third tarsal joints equal, the 

 second minute, simple, compressed. Forceps seldom more than half 

 as long as the abdomen; in the male, simple, arcuate, horizontal; in 

 the female, simple, straight, inc'urved at the tip, unarmed. 



This genus differs from the preceding principally in the simple 

 character of its middle tarsal joint, and in the 

 shorter obconic joints of the antennse. Four 

 species are accredited to the United States, one of 

 which occurs in Indiana.

Antennae 10-12-jointed. Pronotum narrower 

 than the head, scarcely longer than broad. Teg- 

 mina nearly twice as long as the pronotum, the 

 wings, when at rest, extending fully half their 

 length beyond the tip of tegmina. Forceps of male about three- 

 fourths the length of abdomen, rather heavy, minutely toothed on
