SUBFAMILY II. LABIIXJ-]. 5-> 



jectiug tooth on the last ventral, while the females differ only in 

 the color of the legs. 



7. LABIA REIIM Hebard, 1917, 317. Rehn's Earwig. 



Resembles L. minor in form, size, and pubescence. Color much as 

 there, the sides of abdomen darker. Differs in having the eyes much 

 smaller, only three-fifths the length of cheek, in minor only very slightly 

 shorter than cheek; tegmina shorter, only a little longer than pronotum, 

 in minor nearly twice as long as that organ; wings projecting beyond teg- 

 mina less than half the pronotal length, in minor fully the pronotal length. 

 Forceps of female "with ventro-internal margins not attingent, not per- 

 fectly straight, and armed with microscopic, blunt serrulations." Length 

 of body, 4.5; of pronotum, .9; of tegmina, 1.1; of forceps, 1.4 mm. (Fig. 

 26, a.) 



Known only from the unique female type taken at Key West, 



Fla., July 7, 1912, from between boards in a woodshed. First re- 

 corded as L. minor (7?. & 77., 1914c, 377). An examination of the 

 type at Philadelphia showed it to be very distinct from L. minor 

 in the characters as given. 



III. PROLABIA Burr, lOlla, 60. (Gr "for" + Labia.) 

 "Agrees generally with Labia but the segments of the antennae 

 beyond the third are all short, and generally more or less conical 

 or pyriforni." (Burr, 1911, 57.) TW T O species occur in the south- 

 eastern United States. 



KEY TO SPECIES OF PROLABIA. 



o. Segments of apical half of antennae fusiform; last ventral segment of 

 male only twice as broad as long, the pygidium quadrate; inner 

 wings usually present, shorter than tegmina in the form burgessi. 



8. PULCHELLA. 



aa. Apical segments of antennae strongly clavate ; last ventral of male 

 three times as broad as long, the pygidium tapering behind; inner 

 wings absent. 9. ARACHIDIS. 



8. PROLABIA PULCHELLA (Serville), 1839, 42. Handsome Earwig. 



Dark, chestnut-brown, shining, glabrous; apical third of abdomen and 

 .forceps reddish-brown; antennae dusky, paler at base, 13 15 

 jointed; legs pale yellow. Pronotum slightly longer than 

 broad, sides straight, hind margin broadly rounded. Teg- 

 mina half as long again as pronotum; exposed portion of 

 wings, when present, half as long as tegmina, brownish-fus- 

 cous with a yellow spot at base. Forceps of male slender, 

 about half as long as abdomen, their legs widely separa- 

 ted at base, gently curved, each with a large subbasal tooth 

 on inner lower margin, and usually a smaller one at apical 

 third on upper margin; of female with legs approximate 

 at base, slightly upturned and incurved on apical half, the 

 Male of form i e ft one crossing the right near tips, the inner lower edge 



bitrgessi X 4- 



(After R.&H.) crenulate, and with a blunt tooth at base. Length of body 

 6 6.5; of tegmina, 1.6; of forceps, 2.3 2.5 mm. (Fig. 28.).
