 tennae pale. 2. ANNTUPES. 



1. ANISOLABIS MARITIMA (Gene), 1832, II, 224. Seaside Earwig. 



Blackish or dark mahogany-brown, shining; legs and under surface 

 yellowish; antennae pale brownish-yellow, pubescent, 24-jointed. Legs of 

 forceps of male remote at base, finely crenulate within, strongly curved 

 inwards; of female contiguous at base, crenulate within, feebly curved 

 and usually slightly crossed and bent upward at tip. Length of body, 

 1820; of forceps, 3 mm. 



Dunedin, St. Petersburg!!, Sarasota, Cape Sable, Long Key 

 and Key West, Fla., Dec. 20 Mch. 25. (W. X. B.). Frequent 

 throughout the winter beneatli piles of seaweed, boards, half bur- 

 ied logs and other debris just above high water mark, where it 

 lives as a scavenger. When their cover is removed they run about 

 with abdomen curved upward and forceps widely opened, ready 

 to nip any approaching enemy. Recorded also by Rehn, Hebard 

 and Davis from numerous localities along the east coast of Flor- 

 ida between Jacksonville and Key West; January September. 

 This is a cosmopolitan species occurring in this country along the 

 coast from Maine to Texas, and is seldom found far from salt 

 water. Morse (1910a, 21) states that along the New England 

 coast it hibernates as an adult, the eggs being laid in summer. 



2. ANISOLABIS ANNULIPES" (Lucas), 1847, LXXXIV. Ring-legged Earwig. 



Black or dark brown, shining; legs and under surface yellowish, the 

 middle of femora and base of tibiae usually annulate or ringed with fus 

 cous; antennae reddish-brown, paler at base, 15- or 16-jointed, the thiru 

 and fourth joints from apex usually pale, the last two dark. Forceps of 

 male with legs contiguous only at base, of female nearly contiguous 

 throughout; in both sexes crenulate on inner edge and curved upward 

 and inward at tips, more strongly so in male. Length of body 9 11; of 

 forceps 1.5 2 mm.

14 This species was recently assigned to Ruborcllia Burr; a genus erected for those 

 species which "agree generally with Anisolabis, in which genus it was formerly includ- 

 ed, but which are distinguished by the possession of rudimentary elytra which are 

 never free, but attached to the mesonotum." (Burr, 1911, 30.) Later (1915, 545) he 

 says that the genus Euborellia "is now very much altered," the validity of the feature 

 of the rudimentary wings as a generic character having been rightfully questioned by 

 Zaher. "A remarkable fully winged aberration of aiiniilif'cs having been discovered, 

 Eiiborellia will now contain totally apterous and also fully winged species. It is now 

 to be defined by characters of the genitalia of the male," which he describes and then 

 adds: "Perhaps this feature may be regarded as a generic character," Caudell 

 (Ms.) states that he doubts the validity of Euborellia, as it is "based wholly on a con- 

 cealed genital character present only in the male sex." Since Burr also seems to 

 doubt the sufficiency of his characterization based only on the male genitalia, this ear- 

 wig is here retained under the name by which it has long been known, Anisolabis annulipes.
