Prefemur of anal legs armed ventrally with an ectal series of 3 

 spines and a mesal one of 2; in addition with a strictly mesal series 

 of 3 spines increasing in size distad, and along dorsomesal surface a 

 series also of 3 spines, the distal one of the latter being the corner 

 spine at end of joint. Other articles unarmed and smooth. 



Length, 38 mm. 



Locality. Amballa, India (Rev. M. M. Carleton coll., 1873). 

 The type is in the Mus. of Comp. Zoology at Cambridge. 



Otostigmus simplex sp. nov. 



Type specimens at present much bleached from long preservation 

 so that original coloration cannot be definitely ascertained. At pres- 

 ent they are brownish, with a pale median longitudinal stripe. Legs 

 yellowish. 



Head finely and sub-densely punctate, the punctae being more sparse 

 in the frontal region. A weak median longitudinal furrow midway 

 between sulcus and caudal margin and a more sulciform impression 

 from anterior margin a short distance caudad. 



Antennae composed of 18 articles of which the first three are glab- 

 rous. 



Dorsal plates from the fourth to the penult longitudinally bisulcate. 

 Plates from the 7th or 8th caudad distinctly laterally margined. 

 Finely punctate, but otherwise very smooth, showing no carinae, or at 

 most on some of the caudal plates with a median one obscurely set 

 off by 2 faint longitudinal furrows. 



Last dorsal plate with caudal extension sub-triangular, the lateral 

 portions straight or nearly so from corners to median line, the median 

 angle narrowly rounded. 



Prosternal teeth 5 4- 5 ; all teeth well rounded and the more mesal 

 ones appearing as mere crenations in the dental plate, the ectal ones 

 better separated and more angular. Process of femuroid of pre- 

 hensors large; with a single rounded crenulation or tooth on ectal 

 side and two on the mesal. 



Ventral plates all finely punctate. Wholly lacking true sulci ; but 

 each with a broad longitudinal depression or furrow on each side 

 which does not reach either the anterior or the posterior margin; in 

 addition there is a much smaller median foveola or depression imme- 

 diately in front of the caudal margin. 



Last ventral plate narrowed caudad, the converging sides straight, 

 excepting at ends, where they are convex, caudal margin distinctly in- 

 curved. Convex, smooth and without furrows, excepting for a me- 

 dian longitudinal one over the caudal third of length. 



Coxopleurae produced beyond the last ventral plate two-thirds to
