of some Oriental Genera of )!\y'^d\omoxv)\\di. 1C9 



At present I am disposed to think that, on the whole, tlie 

 most primitive of these frroups is C or D. For example, 

 the strikers on tlie mandible in C are much less specialized 

 than in A or B, since they are clearly nothing but long 

 thickened hairs, whereas in A and B the hairs have been 

 modified into granuliforra spicules or genuine rigid spines. 

 Moreover, A appears to be more specialized than B in the 

 great develo])ment of its scopulje, which, I take it, is a criterion 

 of specialization. In the same way E is more specialized 

 than C, and thus approaches A ; and, lastly, if the larger 

 size of the fourth leg is a primitive character, as seems not 

 unlikely, the group D is more primitive than C. 



N.B. — The species coming from British India, Burma, and 

 Ceylon, which are here briefly described, I propose to discuss 

 at greater length on some future occasion. 



Synopsis of the Genera. 



a. Coxa of palp furnished inside with scattered irre- 



gularly arran<red longer and shorUir spines and 

 spiniform sette ; without a fringe beluw the 

 suture ; mandible with a few iiTegularly ar- 

 ranged, long, stout, but apically tiliforni setre, 

 mixed up with the iuferi(jr fringe of red hairs. . Haploclastus, Sim. 



b. Coxa of palp furni-shed inside with a cluster or 



row of club-shaped rods. 

 a'. The outer surface of the mandible furnished 

 below and behind with long stout setie, as in 

 Hajdoctaatus ; the inner surface of the coxa 

 of the palp withuut so definite a fringe below 

 the suture, the " keys '' comjwsed of a thick 

 cluster of club-shaped rodd (except I'mlmo- 

 piiux). 

 a''. Legs of the fourth pair noticeably stronger 

 than those of the first and clothed dis- 

 tally with long erect setjc ; tarsal pads of 

 the fourth leg completely divided by a row 

 of setje. 

 a'. The fourth leg stouter than the first, its 



firotarsal pad entire and extending, at 

 east on the inner side, almost up to the
