which are united above by eight unequal scuta. Antennae of a 

 pale colour, as long as the body, finely setaceous with three prin- 

 cipal joints, each of which is numerously articulated. External 

 maxillary feet or mandibles strong, subulate, incurvate, four- 

 jointed. Maxillary palpus io\xv-]o\i\iQdLf hairy, or rather spinu- 

 lose, longer than the mandibles. Eyes large, hemispherical. 

 Eeet very long, fifteen on each side, with the last pair twice as 

 long as the others. The principal articulations of the legs, viz. 

 the two femoral joints and the tibiee, are armed with stiff setae. 

 The tihi(c are flattened, angular, and of a pale colour, marked 

 - with transverse bands of a blueish-black. The tarsi are filiform, 

 numerously articulated, and ending with a single subulate claw ; 

 and, with the exception of the hinder pair, which are trans- 

 versely banded like the tibise, are of a pale-yellow colour. 



" The longest specimen hitherto examined was one inch and a 

 quarter in length from the base of the antennse to the tail. 

 Antennae one inch and a half; and posterior legs 2^*^ inches. 



" This insect is found in damp houses under floor mats in all 

 parts of Bengal, Bahar, and Orissa, but mostly during the rainy 

 season, as Jlligerhas observed of his C. lineata. When living, 

 the colours of the back and legs are bright, and varied between 

 yellow, black, and brown ; and although the above description 

 by no means corresponds with the Cermatia livida described by 

 Dr. Leach in the third volume of the Zool. Miscellany ^ it appears 

 to answer to that of the Scolopendra hngicornis of fabricius."
