446 PERCY SLADEN TRUST EXPEDITION 
Loc. Seychelles: Silhouette, VIIT. 1908. 
One specimen. A worn male from the Cascade Estate, Mahé, with more slender 
setee, may belong here. A. small form, with depressed mesosternum, fine, sinuous elytral 
strize, nodulose alternate interstices, and stout, blunt setze on the upper surface and legs. 
The prothorax is without definite prominences. 
BARIDIOMORPHA, nh. gen. 
Rostrum parallel-sided, feebly curved, moderately stout, in repose reaching as far as the 
posterior margin of the anterior cox ; rostral canal very deep, closed behind by the arcuate 
mesosternal process, the latter raised above the level of the metasternum and narrowly 
extending backwards between the middle cox ; metasternum long, the intercoxal process 
narrow, truncate in front; antennee inserted at above the basal third or fourth of the 
rostrum, slender, short, the club ovate; mandibles bifid at the tip; prothorax as long as 
broad, narrower than the elytra, cucullate in front, deeply bisinuate at the base; scutellum 
small, depressed ; elytra elongate, subparallel; ventral segment 2 nearly as long as 3 and 
4 united ; intermediate coxe narrowly, the posterior coxee somewhat widely, separated ; 
legs rather short, stout; femora unarmed, clavate; tibize short, sinuate within, the 
intermediate pair toothed at the outer apical angle; tarsi narrow, joint 3 bilobed, 
pubescent beneath, the claws simple, slender, free; body elongate, narrow, densely 
squamose. 
Type, B. triplaris. 
The type of this Cryptorrhynchid genus has the general facies of an elongate, narrow, 
densely squamose Barid. It is unknown to both Dr Heller and myself, and I cannot 
suggest any nearly allied form. 
64. Baridiomorpha triplaris, n. sp. (Pl. 24, figs. 36, 36a, 3.) 
Rather convex, black, the tarsi piceous; variegated with a dense clothing of brown, 
white, and black imbricate scales—the black scales condensed into various irregular 
coalescent markings on the prothorax and elytra, and the white scales into a large patch 
on each side of the prothorax at the base and numerous small scattered spots—intermixed 
with semi-erect, curled, blunt setze, the setze on the elytra uniseriately arranged down each 
interstice. Head closely punctate beneath; eyes large; rostrum (%) closely punctate to 
the apex, (?) a little longer and smoother, densely squamose at the base. Prothorax 
somewhat rounded at the sides to the narrower, subtubulate, anterior portion, densely 
punctate. Elytra subparallel, broadly produced at the apex; conspicuously punctate- 
striate, the interstices flat and densely punctate. Beneath densely, finely punctate, the 
metasternum and first two ventral segments with coarse punctures intermixed; meta- 
sternum sulcate down the middle posteriorly, broadly depressed down the middle in ¢. 
Length 34—4 mm. (9). 
Loc. Seychelles: Mahé, Silhouette. 
Twelve examples, all males but two, showing very little variation. Found in 
Silhouette in the high country near Mont Pot-a-eau and at the Mare aux Cochons, and 
in Mahé in the high forest of Morne Blane and Pilot.
