REPORT UPON TWO COLLECTTONS OF MYRWPODA. 1C9 



wider, bearing a strong curved pointed tooth, and a lower, longer, 

 more slender, bearing an apical curved spine, and posteriorly more or 

 less membranous. 



Several specimens from Madras (Mr. Tburston). 



This species, with which I have great pleasure in associating 

 Mr. Thurston's name, appears to fall into the same category as 

 Sp. rogcsioi Karsch from New Hanover. It, at least, however, differs 

 in having the coUum not marked with a sulcus, and the second 

 somite below produced forwards. 



8jnrohohis uroceros, sp. n. 

 (PI. ii, fig. 7.) 



Colour : the posterior half of the segment probably piceous and the 

 anterior more or less cinereous ; face, antennae and legs ochraceous. 

 Face tolerably flat, with a short frontal sulcus, and a conspicuous long 

 sulcus dividing the labral region, punctulate, with four labral pores, 

 two near the middle and two at the sides ; antennce short although of 

 normal length for the genus ; eyes composed of about 43 ocelli 

 arranged in 6 or 7 transverse rows ; the distance between them about 

 equal to a diameter and a half. 



Collum punctulate, coarsely punctured along its posterior border ; 

 neither striate nor sulcate laterally, and with an almost obsolete 

 marginal sulcus, the anterior angle nearly a right angle, the pos- 

 terior angle widely convex, the posterior border sloping obliquely 

 backwards and upwards from the posterior angle ; the 2nd segment 

 projecting inferiorly below the level of the first, with its inferior 

 portion produced forwards to a point on a level with the anterior 

 angle of the collum. The hinder half of all the segments, except 

 the first and last, furnished posteriorly with distinct coarser and 

 finer tubercles, which gradually disappear inferiorly and laterally, 

 and give place to longitudinal striae, the anterior portion, lower than 

 the posterior portion, nearly smooth, the sterna striate. The anal 

 somite of large size, punctulate, compressed above and produced into 

 a long, stout, smooth, pointed, slightly down-turned caudal process . 

 margins of the anal valves strongly compressed. Pores situated in 

 front of the transverse sulcus and above the middle of the side ; the 

 first on a level with the rest. Ventral grooves short. 



Legs with a single seta on the under surface of each segment.
