NEW PHYTOPHAGOUS COLEOPTERA 75 
antennae nearly as long as the body, testaceous, the last two 
joints fuscous; the fourth joint slightly longer than the third. 
Hab. New Guinea, Fly River (L. M. D’Albertis). 
The single specimen before me agrees in the main points 
with the structural characters peculiar to Sastra but differs in 
the shape of the palpi and in the proportionate length of the 
joints of the antennae; it is therefore probable that the insect 
represents an allied but distinct genus. 
49. Sastra suturalis, n. sp. 
Flavous; antennae (the basal joints excepted) fuscous or black; 
thorax finely and remotely punctured with 2 depressions; elytra 
closely punctured and finely transversely rugose, violaceous blue, 
the margins narrowly flavous. 
Length 3 lines. 
Head with a few very fine punctures, the vertex with a 
narrow central longitudinal ridge running to the epistome ; 
frontal tubercles not strongly developped, trigonate; labrum, 
jaws and the palpi, testaceous; antennae two thirds the length 
of the body, the basal joints more or less stained with flavous 
below, the others nearly black, the third joint about one half 
longer than the fourth, nearly three times as long as the second 
joint; thorax more than twice as broad as long, the sides sub- 
angulate at the middle, the angles acute but not produced, the 
surface with a transverse fovea at each side and another trans- 
verse narrow depression near the anterior margin, another 
illdefined shallow groove may be seen at the centre of the 
disc, the latter with a few scattered punctures near the ante- 
rior and basal margin, flavous, shining; scutellum broad, im- 
punctate its apex obsoletely truncate; elytra parallel, impube- 
scent, finely and very closely punctured also very finely 
transversely rugose or wrinkled, the entire disc violaceous blue, 
the basal, sutural and lateral margin flavous, their epipleurae
