tfiinsverse, broadest at the base, rapidly narrowing in front, 

 tlie sides strongly rounded and deeply constricted before the 

 apex; the ai)ieal marj^in slij;;htly j)roduced dorsally, the 

 postocular lobes small and fringed with long vibrissae; 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. Elytra broad, suboblong, much 

 broader than the prothorax, widest at tlie 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 

 setie; the epipleural carina running from the middle of the 

 metasternum to the apex of the third apparent ventrite. 

 Legs (fig. 1, A-) 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 tibiae more shallowly punctate, the front 

 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. Sternu7n with all the coxse 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'o mm., breadth 4"25-5*5 mm.

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. n. 



"When dealing a few years ago with the species oi Alcides 

 allied to .4. dtltu, Vase. (*Ann.& Mag. Nat. Hist. (9) ii. 1918, 

 pp. 152-157), I unfortunately overlooked a paper by Faust 

 in which two species of this group were described (Stettin, 

 ent. Zeit. 189(J, pp. 149, 150). Of these A. perturbatu^, Fst.,
