Male (Figs. 272-276) : Body long-oval, narrower in front, yellow. 

 Scutum (3'5 x 21 mm.), very long and narrow, indistinctly denned, not 

 covering the whole dorsum (which is concave in the specimen described), 

 convex along the median line ; emargination slight ; faint, rapidly 

 diverging cervical grooves commencing at some distance behind the 

 anterior border; no lateral grooves in the usual situation. Coarse 

 punctations forming a single longitudinal median row and two lateral 

 rows; numerous very fine punctations over the rest of the scutum. Venter 

 (Fig. 272): genital orifice facing the second intercoxal space; median 

 plate pentagonal, fairly broad ; anal plate long-oval ; adanal plates very 

 long ; all the plates with numerous punctations. Spiracles very large, 

 subcircular. Capitulum (Fig. 273 ; - 65 mm. I. dorsally) comparatively 

 small, base about as broad as long, dorsal ridge convex, the dark raised 

 ridge extending for a short distance along the lateral borders. Palps 

 clavate, convex dorsally, with numerous long hairs, article 2 about equal 

 to article 3. Hypostome (Fig. 274 A) ill-defined, practically smooth, but 

 with indications of a few small scale-like teeth distally. Digit (see Fig. 

 274). Legs (Figs. 275, 276) of inordinate length, every article, except 

 the coxa, being remarkably elongate. Coxae unarmed.
