410 On new Alcides from the Oriental Region. 
transverse, broadest at the base, rapidly narrowing in front, 
the sides strongly rounded and deeply constricted before the 
apex; the apical margin slightly produced dorsally, the 
postocular lobes small and fringed with long vibrisse; the 
dorsal outline flat from the base to the constriction, then 
sloping slightly ; the dorsum closely set throughout with 
low rounded tubercles. Scutellum entirely enclosed in front, 
small, elongate, bare, Hlytra broad, suboblong, much 
broader than the prothorax, widest at the shoulders, which 
are acutely prominent, broadly rounded behind, the extreme 
apices dehiscent, the basal lobes strongly produced, and a 
shallow semicircular depression round the scutellum ; the 
punctures very coarse and deep, especially in the area 
between the shoulders and the transverse band; the in- 
tervals narrower than the punctures, rugulose, shiny, and 
with sparse, small, plumose scales and minute recumbent 
set; the epipleural carina running from the middle of the 
metasternum to the apex of the third apparent ventrite. 
Legs (fig. 1, k) piceous, with numerous oblong fringed 
scales; the femora with very coarse confluent punctures and 
with a stout blunt tooth, which is largely hidden by long 
curved scales ; the tibiz more shallowly punctate, the frout 
pair with a sharp tooth on the inner edge about the middle 
and another at the apex, the other pairs with only the apical 
tooth ; joint 2 of the front tarsi twice as long as broad, with 
the inner (or anterior) lobe longer and narrower than the 
other. Sternum with all the coxze more widely separated 
than usual; the metasternum rugose and depressed in the 
middle in both sexes, and coarsely granulate at the sides. 
Length 8°5-9°5 mm., breadth 4°25-5°5 mm. 
Invo-Cu1na: Hoabinh, Tongking, vill. 1918 (R. Vitalis 
de Salvaza, type). Assam. 
Described from twenty-four specimens. 
This striking species may be readily recognised by its 
unusually flattened form, pointed shoulders, and very narrow 
straight rostrum. The specimens from Assam constitute a 
rather smaller local race, characterised by its much less 
prominent shoulders, and may be designated Alctdes vitalisi 
subhumerosus, subsp. 2, 
When dealing a few years ago with the species of Alcides 
allied to A. delta, Pase. (Ann. & Mag. Nat. Hist. (9) 11. 1918, 
pp. 152-157), I unfortunately overlooked a paper by Faust 
in which two species of this group were described (Stettin. 
ent. Zeit. 1896, pp. 149, 150). Of these A. perturbatus, Fst., 
is obviously the same as A. yavanodelta, Mshl., and the latter
