Ewing — New Acarina from India. U 



.- 



Body almost twice as long as broad, strongly constricted in front 

 of the shoulders, sides almost straight, and on the dorsal side evenly 

 rounded behind. Dorsally, abdomen sparsely clothed with minute 

 hairs. On the ventral side, the ventral plate projects beyond the dorsal 

 margin of the abdomen immediately behind the anus. Anus small, 

 circular and situated about twice its diameter from the posterior mar- 

 gin of this ventral plate. 



Second pair of legs of the male enlarged and with a prominent tooth- 

 like projection on the femur. The coxae of the posterior pair of legs 

 are nearer together than the coxae of the other two legs. 



Length, 0.78 mm.; breadth, 0.42 mm. 



In moss. I was unable to find any living specimens 

 of this species, for all of the specimens evidently had 

 been dead before the moss was collected, as they were 

 mostly in bad shape and were only empty shells. By 

 putting together some seven or eight of these dead, shell- 

 like specimens all the important characters could be ob- 

 tained. Nilgiri Hills, South India. 



gamasus Latreille. 



Peritreme more than twice as long as broad; legs of the first pair 

 provided with claws; dorsal shield entire; genital opening of the male 

 at the anterior margin of the sternal plate; legs of the second pair 

 in the case of the male frequently enlarged and armed with chitinous 

 tubercles; epigynium of female triangular. 



One species. 



Gamasus dentatilinea n. sp. 



PI. XXXV. f. 5. 



Female. In general appearance a very light yellowish brown. 



Mouth-parts prominent; epistoma large, rectangular; from each lateral 

 anterior corner there projects a prominent, sharp cusp; palpi about 

 one-half as long as the first pair of legs, last segment equal in length, 

 but much narrower than the penultimate; from the inner, distal edge of 

 the penultimate segment there arises a sharp spine almost as long as 

 the segment itself; antepenultimate segment slightly longer and wider 

 than the penultimate; mandibles long and stout, and when extended 

 they may reach beyond the tips of the palpi, constricted at their middle 

 where there is a very long bristle at each side equal to one-half the 

 total length of the mandible; chelae of the mandibles stout, almost 

 straight, and each with a row of subequal, sharp teeth which extends 

 the entire length of the same on its inner margin, hence the name, 

 dentatilinca. 



Abdomen almost twice as long as broad; margin slightly concave in 

 front of the shoulders and broadly and evenly rounded behind. Ab-
