side beyond coxae I, and extending np to the middle of the length 

 of the base of the rostrnni ; cervical grooves deep, converging at first, 

 then diverging, becoming wide and shallow ; lateral grooves beginning 

 jnst behind the eyes, and widening as they proceed candad ; eyes black, 

 hemispherical, shining, in a snb-marginal pit near the anterior 

 quarter; punctuations numerous, unequal, scattered over all the 

 surface, large and abundant near margins; a few very short hairs, 

 sometimes three posterior grooves, the median longer, eleven posterior 

 marginal festoons ; the median inclined io be triangular ; two dorsal 

 porose areas, one on each side and close to the median line, near 

 middle of length of shield, dark coloured and difficult to see. Yentnd 

 ■ surface yellowish white or brownish ; numerous short hairs ; sexual 

 orifice opposite first inter-coxal space; anus near posterior third, 

 opposite stigniatic plates ; anal plates of a deep brown, more or less 

 elongate, narrow, outer margin reaching almost to level of anterior 

 margin of stigniatic plates, inner margins longer than posterior, and 

 slightly concave, posterior margin truncate; punctuations few, large, 

 a few stout whitish hairs : outside of each anal plate and separated 

 from it by the coxal groove, is a very narrow elongate, accessory 

 plate, chitinous only in its caudal third ; opposite and behind each 

 anal plate is a conicle prominence, chitinous, dark brown, some- 

 times passing beyond the posterior margin ; stigniatic plates in the 

 form of a very elongate comma, the posterior extremity of which 

 nearly reaches and sometimes passes l)eyond the level of the extremit^v 

 of the accessory anal plates; ano-iiiargiiial groove well markei. 

 Rostrum elongate; base much wider than long; posterior angles 

 sc?.rcely salient; lateral edges convex; a few large punctuate /ns on 

 ■dorsal surface, sometimes in a transverse line; ]iiandibles with innei' 

 apophysis narrow at base, with tip slightly recurved, transverse 

 process a little below anterior extremity bearing two teeth, the lower 

 .slightly larger than the upper; outer apophysis with two teeth, lower 

 one stronger, hypostonie spatulate, rounded at tip with numerous 

 denticles, then three rows of ten to twelve teeth on each half, sharply 

 pointed, outer row longer, below these the teeth are squaniiforiii 

 in three rows extending almost to the base ; palpi elongate, narrow, 

 valvate ; article I with dorsal face a half shorter than ventral face, 

 which is prolonged on the inner edge in a longitudinal apophysis, 

 longer than the article, inner edge bears long hairs directed inward 

 and forward ; article II a little shorter than article III on the ventral 

 surface, prolonged on its dorsal surface into an obtuse, flat point, 

 fitting over article I, long hairs on the inner margin of articles II 

 and III ; article III as long' as wide ; article lY very small, a mere 

 hairy papilla in a ventral pit of article III. Legs long and stout, 

 pair IV passing beyond the posterior end of abdomen by the last two 

 articles or less; articles III, lY, and Y reddish brown, ringed with 

 whitish on distal halves ; tarsi I unarmed, a false terminal article 

 in form of a truncate cone, widened behind false articulation ; those 

 of other legs with parallel sides, gradually attenuated on their dorsal 

 margins, two short, stout spines ; tarsi lY at least four times as long 

 as wide; caruncle short, reaching scarcely half the length of the 

 claws; coxae large, almost contiguous, dark brown, coxae I divided 

 into two long teeth, the inner shorter and wider, a tuberosity near the 

 postero-external angle of coxae II and III ; one on each posterior 

 angle of coxae lY.
