250 Mr. E. I. Pocock on some 



young examples of a si)ecies of SpirohoJus, which will probably 

 prove to be the same as avcnms. 



Spirostreptus Gulliveri, Butler (ibid.), from llodriguez, belongs to the 

 same group as all the Madagascar species. The segments are 

 strongly sulcate, being posteriorly nearly smooth above, but 

 decorated with an obscure anastomosing pattern of low ridges ; 

 the anal valves are convex, with their borders uncompressed. 



SjiiroholKS hecate, Butler {ibid.), from llodriguez, is a iSpirostrfiptas, 

 allied to all the known Madagascar forms. The posterior part 

 of its somites is thickly puuctulato and striolate, and the 

 margins of the anal valves are compressed. 



Part II. — Descriptions of some New Species. 



Sjnrostre^Jtus stenorhynchus^ sp. n. (PL XVI. figs. 1—1 d.) 



Closely allied to 8. Lunelii of Humbert, of which kandy- 

 anus, Humb., is probably the young. Both of these have been 

 well figured and described, so that a brief diagnosis of this 

 new form will suffice. 



Colour jet-black, shining, and polished, tergites paler in 

 front ; lower half of head and antennae ferruginous, legs clear 

 yellow. 



First tergite with a fine anterior sulcus in front of the mar- 

 ginal sulcus ; the anterior angle very obtuse in the female, 

 rounded in male, and a little produced. In the anterior half of 

 the body the tergites are dorsally smooth or nearly so, but in 

 the posterior half they are distinctly punctulate and striolate 

 dorsally ; the lateral strijB do not in any of the segments unite 

 with the transverse striolas of the anterior half. The ventral 

 grooves are short, and the sterna are striolate. Anal somite 

 as in Lunelii. Leys with a series of hairs i^about 4) on the 

 lower surface of each segment. 



Cojjulatory feet diftering from those of *S'. Lunelii \n that the 

 anterior lateral lamina bears three teeth, of which the inferior 

 is the longest and the upper the shortest ; in S. Lunelii the 

 middle one is much longer than the inferior, and the upper one 

 of ^S*. stenoriiynchus is absent ; the protrusible lamina is distally 

 bifid, the external ramus is short, curved, and sublaminate, 

 the internal very long, curled upon itself, and flagelliform. 



Loc. Ceylon [Cuming) ; Punduloya (Ceylon), collected 

 and presented by Mr. E. E. Green. Also anotiier example 

 without locality. 



Sjnrobolus eryt/irocejjhalus, sp. n. (PI. XVI. figs. 2-2 b.) 

 Colour. Head, legs, and antennte blood-red; first tergite 

 almost entirely of the same colour, but with a large black 

 patch on each side above the lateral angle, the two patches 

 connected across the middle line by an ill-defined shadowy 

 fuscous band, which is darker on the middle; the second, 

 third, and fuurth tergites black at the sides, blood-red above,
