guarding a tiny heap of eggs which she immediately started to re- 

 move, carrying two or three eggs at a time to a spot an inch away. 

 These earwigs were often found near nests of a small stocky red ant, 

 which species did not seem to interfere with them at all. It was 

 possible to obtain so large a series owing to the fact that the 

 hurricane of the previous summer had blown down quantities of 

 cocoanut palms; these prostrate or half-prostrate trees were exam- 

 ined and about half were found to contain specimens of this earwig. 

 In the large series before us we find the length of the females to be 

 from 4 to 5 mm., and that of the males from 4 to 5.5 mm.; a few 

 other specimens would exceed this maximum, but are found to be 

 squeezed to an unnatural length. The great majority of adults in 

 the series are very near 4.5 mm. in length. Among the specimens 

 taken are two females which had but recently reached maturity and 

 are colored uniformly pale, wood-brown. This species is found 

 around the world in tropical latitudes; it was described from the 

 Nura Ellia Mountains of Ceylon. 



Prolabia unidentata (Beauv.). 2 



Labia burgessi Sc. 

 Labia guttata Sc. 



Miami, Fla., March 27, 28, 1910; 7 d\ 7 9,2 9 n. 

 Homestead, Fla., March 17-19, 1910; 3 cf , 6 9,1 9 n. 



One male specimen from Miami has the usual median tooth on the 

 internal margin of the forceps lacking, while the other individuals 

 of that sex show this tooth varying from a very blunt to a strongly 

 marked protuberance. We have followed Burr in using this specific 

 name for the wingless form generally called burgessi Scudder. All 

 of the present series lack wings. The specimens were all taken from 

 under the bark of dead pine logs in the pine woods. 



BLATTIDiE. 

 Ischnoptera deropeltiformis (Brunner). 



Homestead, Fla., March 17 19, 1910; 2 d% 1 9 , 1 & n, 2 9 n. 



Both of the adult males have the tegmina 15 mm. in length, this 

 being slightly smaller than the measurements previously given by 

 the authors as the minimum for the species. The adult female, 

 on the other hand, is slightly above the average size. In all the 

 specimens the femora and tibiae are similarly colored. This species, 

 previously recorded as far south as Miami, Fla., was found under
