AETHEOPOD FAUNA OF THE WEST INDIES. 503 



Number of segments 50. 



Length 51 mm. 



Locality. A single male from St. Lucia {G. A. Ramage). 



Differs from B. monilicornis in that the sulcus of the segments 

 is incomplete dorsally, &c. In this respect it apparently resembles 

 M. jlavo-cingulatus of Karsch from Caraccas, but the two may 

 certainly be distinguished by the shortness of the caudal process 

 in this species. 



Hhinoceicus leptopus, sp. n. 



Closely allied to B. serpentinus. 



Colour entirely black. Legs fusco-ochraceous. 



Body long and slender. 



The transverse sulcus complete, except on the posterior 

 segments, where it disappears ; the posterior part of the seg- 

 ments longitudinally striate inferiorly, the anterior part obliquely 

 and transversely striolate, a conspicuous stria rising about on a 

 level with tbe pore, crossing the vertex from side to side. 



Scohina present. Anal segment as in B. serpentinus. 



Legs much longer than in R. serpentinus. 



Number of segments 49. 



Length 53 mm., width 4-5 mm. 



Locality. St. Lucia ( G. A. Bamage). 



A single female example. 



Ehinoceicus tincentii, sp. n. (PI. XXXVIII. fig. 10.) 



5 . Short and robust. 



Colour (in alcohol) black, the posterior border of the tergites 

 obscurely ferruginous ; antennae, legs, and labral border reddish 

 yellow. 



Head smootb, the sulcus deep below and above, obsolete in the 

 middle ; labral punctures 2+2. Antennm shorter than the 

 face. Eyes separated by a space that is equal to more than three 

 diameters, composed of about six transverse rows of ocelli. The 

 first tergite smooth, evenly rounded laterally, with an anterior 

 marginal sulcus, not reaching so low as the second. The second 

 somite flat beneath. The rest of the segments shining but punc - 

 tulate and striolate ; the transverse sulcus well marked at the 

 sides and punctured, fading away dorsally, where its place is 

 taken by a secondary sulcus which rises on each side just above 

 and in front of the pore ; the inferior portions of the segments 

 longitudinally sulcate both behind and in front of the sulcus.
