broader at the shoulders than the prothorax, the basal lobes 
not very strongly produced, the apices jointly rounded ; the 
strize with comparatively small shallow punctures and not 
deeper or noticeably curved at the base; the intervals with 
irregular low granules, which are more numerous on the basal 
half and absent from the squamose areas, the darker areas 
with numerous short, recumbent, pale sete ; a very shallow 
curved impression just behind the scutellum. Legs com- 
paratively short, shallowly punctate, and rather thinly 
covered with linear scales ; the femora with a short simple 
tooth almost hidden by setee ; the tibize almost straight on 
the outer edge, the front pair not toothed on the inner edge 
and only faintly bisinuate (fig. 1, 6). 
Length 65-8 mm., breadth 3-3°5 mm. 
Manpras: Kodaikanal (7. V. Campbell, type) ; Palni Hills,

Described from ten specimens. 
Closely resembles A. audax, Heller, in general facies, but 
in that species the humeral stripe on the elytra is replaced 
by a subhumeral spot, the oblique posterior stripes meet on 
the suture in front of the middle and do not extend along 
the lateral margin to the apex, and the non-squamose areas 
of the elytra bear only sparse inconspicuous dark sete. 
Alcides trigonophorus, sp.n. (PI. VII. fig. 10.) 
dg ?. Form subelliptical; integument black, thinly clothed 
with short, recumbent, brown sete and marked with narrow 
pale lines formed of whitish scales that are narrowly bifid or 
trifid to the base ; the prothorax with five sharply defined 
pale stripes, the upper lateral one terminating at the base 
opposite the shoulder of the elytron, the lower lying below 
the level of the lateral margin of the elytron; the elytra 
with a subtriangular marking formed by a narrow oblique 
line on each, running from the base of stria 1 to behind the 
middle on interval 9, and there connected together by a post- 
median curved line of the same width; a pale line on 
interval 9 from the base to one-third the length and another 
at the apex of iiterval 38; the lower surface clothed with 
numerous brown plumose scales. 
Head with shallow confluent punctation and narrow split 
scales, the forehead transversely unpressed. Rostrum long 
and slender, slightly widened at the inserticn of the antennz 
(beyond the middle in both sexes) and again at the apex, 
rather strongly punctate throughout (except at the extreme 
apex in the ¢), but the punctures on the posterior part
