THYSANURA AND TERMITID^

Several specimens from Hood Island in May. The largest species 

 known to me. 



LEPISMA INSULARIS sp. nov. 



Length 7 mm., width of prothorax 1.4 mm. Body with light 

 brownish scales, some specimens show the abdomen more or less 

 banded ; legs pale, with many hairs ; 

 antennae and cerci pale, but more 

 or less distinctly annulate with dark. 

 Head more conical than preceding 

 species ; there is a crest of hairs over 

 base of each antenna, and a few scat- 

 tered groups on anterior margin. 

 The maxillary palpi have the last 

 joint a little longer than preceding 

 joint, the intermediate joint a little 

 longer than any of the others. The 

 labial palpi have the last joint ob- 

 scurely triangu lar. The antennae are 

 about the length of the body, and 

 the cerci are plainly shorter than 

 body. The telson is broadly trian- 

 gular and rounded at tip. The legs 

 have the usual stout spur at upper 

 tip of each tibia. There are no 

 distinct groups of pores on the 

 thoracic segments, but on the ab- 

 dominal ones there is on each side 

 near the edge of body an obliq'ie row of three pores. 



Several specimens from Narboro Island and one from Tagus 

 Cove, Albemarle Island, all in January.
