as long as the mesothorax, and simple, each slightly dilated 

 at its hind extremity for the insertion of the legs, and 

 marked with a luteous lateral line edged on each side with 

 black. The abdomen long, slender and simple, the seg- 

 ments rather thickened at the base and apex ; the three 

 terminal segments short, forming an elongate-ovate mass ; 

 the ninth being deeply cleft down the middle behind, its 

 two divisions being incurved at the extremity, and their 

 inner and under edges armed with minute transverse teeth ; 

 the three terminal ventral segments are short, scarcely ex- 

 tending beyond the base of the ninth dorsal segment, and 

 exposing the insertion of the two curved setose anal styles. 

 The legs (especially the anterior pair) are long and slender ; 

 the four posterior femora slightly thickened, and armed 

 beneath near the tips with two or three minute spines ; 

 the two posterior tibise are also slightly serrated towards 

 their tips.

Elongate, subcylindric, rather slender ; obscure buff, 

 with slight brown markings ; entirely smooth, and destitute 

 of spines, tubercles, or granules. Tbe head is oblong, 

 scarcely attenuated behind. The antennas long, slender, 

 mul Particulate ; the basal joints subdepressed. The meso- 

 thorax is comparatively very long, and is rather narrowed 

 towards the fore part. The metathorax is rather more 

 than one-third of the length of the mesothorax ; its hinder 

 portion occupies about two-fifths of its whole length. The 

 abdomen is subcylindric, with the six basal segments sim- 

 ple (the remainder are broken off in the unique specimen 

 before me). The legs are moderately long ; the femora of 



all the legs are angulated, and armed near the tips beneath 

 with a minute spine ; the tibise are slender and simple, and 

 the basal joint of all the tarsi is about equal in length to 

 the three following joints.

Allied to Lonchodes brevipes, fern., but narrower, and at 

 once distinguished by the less-developed appendages of the 

 legs, by the black tubercles on the thorax, and by the acute 

 decumbent spine on the fourth segment of the abdomen. 

 The body is long, rather slender and subcylindrical, opake, 

 obscure luteous-brown, slightly rugose ; the meso- and me- 

 tathorax being moreover marked with a number of mode- 

 rate-sized black oval tubercles. The head has a sinuated 

 ridge in the middle between the eyes. The antennae are 

 about equal in length to the fore legs. The mesothorax is 

 but slightly dilated at the place of insertion of the middle 

 legs. The metathorax is slightly but gradually widened 

 from the base to the insertion of the hind legs, in front of 

 which is a small but prominent tubercle on each side of the 

 body. The abdomen has the sides nearly parallel, the 

 fourth segment having a small but very acute decumbent 

 spine in the middle of its hind margin ; the fifth and sixth 

 segments are slightly dilated at the sides ; the three ter- 

 minal segments are short and uniform ; the ninth with the 

 lateral apical angles prominent and directed backwards. 

 The operculum extends rather beyond the end of the body ; 

 it is deepest at its extremity, where it is rather abruptly 

 truncate and rugose along the edge. The legs are short ; 

 all the femora with two or three small spines on the under 

 side near the tip ; the fore femora are rugose ; the fore 

 tibise with a narrow membrane along the whole length of
