The front of the mandible studded with thick reddish 

 bristles, intermixed below with the short, blunt, tuberculiform 

 spines which spread upwards from the short angular promi- 

 nence ; lower edge of mandible furnished externally with 9 

 blunt rounded teeth and internally with 7 or 8. 



Labium armed apically with a crescentic series of 6 teeth. 



Maxilla armed in front througliout its length with teeth, but 

 more crowdedly on the two extremities ; the rest of its lower 

 surface studded with short spicular hairs. 



Sternum hairy in front, smooth behind, with only two 

 pairs of impressions, opposite the middle of the cox^e of the 

 legs of the first and second pairs ; the posterior larger, oval, 

 further from the margin than the anterior, the space separating 

 each from the edge being about equal to half its long 

 diameter. 



None of the coxje of the legs spicular, but hairy, the first 

 more so than the second, the second tlian the third, and tlie third 

 than the fourth ; femora of third and fourth infiated below ; 

 patella, trochanter, and femur of palp and of first and second 

 \eg studded in front with stiff bristles, of third and fourth 

 legs nearly smooth ; patella of palp with 1 internal spine and 

 some stiff' bristles, of first and second leg liairy, of third and 

 fourth furnislied with hairs mixed up with short spines ; tibia, 

 protarsus (and tarsus) of palp, and first and second legs 

 thickly spiny in front and behind (externally and internally), 

 though the spines on the posterior surface of the second tibia 

 are only about half a dozen in number ; tibia of third shorter 

 than patella of third, armed like the protarsus with spines in 

 front and behind, the protarsus also armed below with an 

 apical spine, the tarsus apically spined both externally and 

 internally ; tibia of fourth bristly, furnished with only one 

 small anterior spine ; protarsus armed below with 5 spines ; 

 tarsus with many spines and rather thickly hairy. Tarsal 

 claws with one large tooth (with sometimes a smaller tooth at 

 the base of it). 



(Abdomen absent.) 



Length of carapace 8*6 millim., width 7*5.

The genus Heligmomerus, hitherto known only from Ceylon 

 and South India, contains but two species, H. taprobanicus^ 

 Sim., from Kandy, and //. prostans, Sim., from Kodeikanel, 

 South India. This new form certainly differs from both in 

 having the anterior median eyes much nearer to each other 

 than they are to the laterals, for, according to Simon's 

 diagnosis of the genus, these four eyes are equidistant.
