470 PERCY SLADEN TRUST EXPEDITION 
Length 3 mm. 
Loc. Seychelles: Silhouette. 
One male, found in the forest above Mare aux Cochons. This insect is of the size of 
the smaller examples of S. parallela, differmg from that species in its more convex, 
subeylindrical shape, and in having the head shorter and less inflated, the elytra relatively 
shorter, the ventral segments 2 and 5 unimpressed (2), and the sides of the metasternum 
less depressed and smoother. 
94. Stenotrupis biformis, n. sp. 
Very elongate, narrow, subfusiform, somewhat depressed, shining, ferruginous, the 
apex of the elytra sparsely pilose. Head and rostrum closely, minutely punctate, the 
latter much smoother and more shining in ?; rostrum (¢) feebly curved, very stout, 
rapidly widened outwards, barely twice the length of the greatly-developed, exposed 
portion of the head, (?) very slender, widened at the apex, and nearly four times the 
length of the head, the antennze inserted at basal third or fourth; head constricted far 
behind the eyes, broad and somewhat oval in 7, smaller, transverse, and more narrowed 
anteriorly in ?, the post-ocular space twice the length of the eyes in g, the latter 
depressed; antennze with a rather large abrupt club, comparatively stout in 3%, slender 
in ?. Prothorax much longer than broad, subconical, rounded at the sides posteriorly, 
constricted just before the apex; densely, minutely punctate, with an indication of a 
smooth median line. Scutellum transverse. EHlytra elongate, subparallel to near the 
apex; closely, very finely punctate-striate, the interstices flat, faintly transversely 
rugulose. Beneath closely, minutely punctate ; ventral segments 1 and 2 deeply sulcate, 
and 5 foveate, in g. Third tarsal joint feebly lobed. 
Length 1,%—275 mm. ($$). 
Loc. Seychelles: Silhouette. 
One male and two females, found in the forest above Mare aux Cochons. In this 
insect the head and rostrum are so dissimilarly formed in the two sexes that the male 
could easily be taken for a different species; the female, too, has the anterior portion of 
the rostrum unusually prolonged. The puncturing of the prothorax is extremely fine and 
close. The general shape of the body is very like that of a small Rhizophagqus. 
95. Stenotrupis tarsalis, n. sp. 
Very elongate, narrow, subfusiform, depressed, alutaceous and opaque above, shining 
beneath ; ferruginous, the eyes black, clothed when fresh with excessively minute hairs. 
Head and base of rostrum densely, the rest of the latter more finely, punctate, the apical 
portion of the rostrum smoother in 2; head in ¢ prolonged in front of the basal con- 
striction, in ? shorter, the post-ocular portion a little longer than the eyes in ¢ and of 
about the same length in 9, the inter-ocular fovea distinct, the eyes small and depressed ; 
rostrum together with the head about as long as the prothorax, subcylindrical, slightly 
widened at the tip, moderately stout in 3g, slender and more curved in §, the antennz 
slender, inserted near the base in ?, and at the basal third in ¢, the club abrupt.
