long as head and prothorax, gently curved. Upper surface convex 

 in basal half and broadly excavate near apex, distinctly punctured 

 and with a broad smooth centi'al line ; latei-al sulci not meeting 

 at base, broad and deep, sepai'ated by a narrow carina and filled 

 with large white scales ; scrobes running beneath base of i-ostrvxm ; 

 inferior basal furrow shallow. Ante7ince with scape not nearly 

 reaching eye ; the two basal joints of funiclesubequal. Prothorax 

 slightly transverse, the length about equal to the width at base, 

 which is broader than apex, sides not much rounded, broadest 

 about middle, ocular lobes sti-ongly developed. Upper surface 

 convex, with distant rounded tubercles, which are flattened and 

 arranged in moi'e or- less regular rows on disk, but smaller, moi-e 

 elevated and irregular latei'ally ; central furrow very broad and 

 containing a short faint carina ; apices of tubei'cles bare, shiny, 

 and with very short depressed setse, the interstices with dense 

 white scaling. Elytra oblongo-ovate, sides scarcely i-ounded, 

 broadest befoi'e middle, shoulders rounded, apical processes very 

 long and sharp. Upper surface convex, sti'iee with regular rows 

 of small granules, the alternate intervals more prominent; intervals 

 1, 4, and 6 entirely devoid of tubercles ; interval 2 with only a 

 single very large and shai'p tubercle on the summit of the declivity ; 

 interval 3 with three lai'ge, smooth, catenulate tvibercles at base, 

 then Avith an irregvilai- I'ow of small rounded tubercles to beyond 

 middle, where they become larger and sharply conical, the largest 

 being at the summit of the declivity, this tubercle is of the same 

 size as, and adjoins, that on interval 2, so as to form a conspicuous 

 transverse row of four large tubercles ; interval 5 with a very 

 large, rounded, boss-like tubercle at base, followed by two similar 

 but much smaller ones, then five or six small gi'anular tubei-cles, 

 and finally two or three lai'ger conical ones beyond middle ; 

 interval 7 with a complete row of small, closely-set, conical 

 tubercles. Legs with dense, even, white scaling ; posterior tarsi 

 with the three basal joints of about the same width, 2nd and 3rd 

 subequal in length, 1st longer. 



Cape Coloxy. 



Type in the British Museum. 



From the other three species which possess the boss-like humeral 

 tubercle nestor may be easily recognised by the very long apical 

 spines and the solitary large conical tubercle on interval 2 of the 

 elytra.
