(d) 9 nifi^^- : length 45 m/m ; diameter 3 m'm ; 61 seg-

Black, legs brown. Body cylindrical, moderately shining. 



Head smooth. Labral notch wide, rounded, provided with 

 five teeth ; labral setiferous dimples 8 -)- 3 to 4 -)- 4. Median 

 sulcus short, to be seen only on the back of the head, abruptly 

 bi'oken off on a level witli the inner angle of the eyes. Kyes 

 divided by a space about equal to the largest diameter of one 

 of them ; ocelli flattened, arranged in four or five series (9-J-8 

 -i-S+S = 33 to 10+9+9 + 8+7 = 43). Distance between 

 the antennae equal to about the length of the three proximal 

 joints. Antenna? i-eaching the posterior margin of the third 

 segment, scarcely clavate, moderately pilose, tipped Avith four 

 sensory cones. Micrometrical measurements of joints : — 1st 

 joint 0.172 m/m ; 2nd, 0.516 m/m ; 3rd, 0.516 m/m ; 4th, 

 0.430 m/m ; 5th, 0.430 m/m ; 6th, 0.473 m/m; 7th and 8th, 

 0.086 ni/m ; total length, 2.623 m/m. Diameter of 2nd joint 

 0.301 111 in ; of 6th, 0.387 m/m. 



First tergite fairly long dorsally. Its sides do not reach 

 as low down as the second segment ; in fact they are slightly 

 angnlai', but, the outer margin being somewhat cui'led in, they 

 appear rounded when seen in profile. Surface smooth dorsally ; 

 the sides bear five or six moderately deep sulci, of which three 

 reach the level of the eyes, the reinaining twt) or three being 

 shortened. The anterior mai-gin is not excised. 



Anterio)', concealed part of prozonite of othei' segments 

 showing weak concentric sti'iiv ; the lattei' ai'e marked now 

 and then with minute, strongly shining gi-anules, which be- 

 come more numerous ventrally. The posterior, exposed part 

 of the prozonite and the metazonite are somewhat uneven, 

 yet without definite sculpture except some tiny longitudinal 

 striae irregularly disposed, but mainly to bo found along the 

 suture. Transverse sutural sulcus well iniii'kt'il all round, 

 usually ijiterrupted on a level with the fii'st or second longitu- 

 dinal sulcus of the metazonite; the following sulci i-eniain
