subcostate, striate beneath ; the anterior part smooth above, 

 striolate below. 



Pores small, nearly in the middle, in front of the transverse 

 sulcus and at the anterior extremity of a longitudinal sulcus. 



Anal tergite produced into a depressed caudal process, which 

 surpasses the valves a little ; valves with widely compressed 

 margins. 



Legs very long. 



Number of segments 40-42. 



Length 60 mm. 



Locality. Cuba. 



EHmOCEICUS GBENADENSIS, sp. n. (PI. XXXVIII. fig. 11.) 



Colour somewhat variable ; the body usually nearly a uniform 

 fuscous anteriorly, but generally richly mottled with black and 

 yellow posteriorly, rarely almost entirely coneolorous, with the 

 posterior part of the segments paler than the anterior ; the 

 collum entirely bordered with a paler band, anal segment and 

 sulcus black ; face infuscate, with a darker patch in the middle ; 

 legs and antennae flavous. 



^ea^, as usual, smooth or nearly so, pores 2+2; antennae 

 short; eyes with indistinctly defined ocelli, widely separated. 

 Collum evenly rounded laterally, with a faint marginal sulcus. 

 The rest of the segments shining, nearly smooth, minutely 

 striolate. The transverse sulcus very strong below, and con- 

 tinued over the dorsum as a distinct depression; the area behind 

 it longitudinally sulcate below, that in front of it obliquely 

 striate below, but none of these striae are continued above the 

 level of the pore, so that there is no secondary transverse dorsal 

 sulcus. Scohina present and extending to about the 27th 

 segment. 



Sterna striate. Pores above the middle of the side, just in 

 front of the sulcus ; their position marked by a faint longitu- 

 dinal sulcus upon the posterior portion of the segment. 



Anal tergite just surpassing the valves, the caudal process 

 bluntly rounded and basally impressed ; the valves lightly com- 

 pressed, but the margins not sulcate ; sternite triangular. 



Legs of moderate size, with a single seta on the lower edge of 

 each segment. 



cJ . More slender than the female, antennae extending beyond 

 the second segment, the legs rather longer. Some of the
