the portion of the first ventral segment behind the coxa ; the

intercoxal process broad and angulate ; plate 1 with its hind — 
margin sinuate ; plate 2 as long as 3+4. Legs short; thie 
femora neither dentate nor suleate beneath, the hind pair not 
reaching further than the apex of the fourth ventral plate ; 
the tibie curved at the base and somewhat compressed, 
uncinate, and with an additional shorter perpendicular spur a

Type. Styracopus phaseoli, sp. n. 
The species upon which this genus is founded has quite 
the appearance of asmall Tyrannion, Chmp., but differs from 
that genus in its stout rostrum, minute scutellum, and unarmed 
femora, and also in having an additional inner spur at the 
apex of the tibiee. 
Styracopus phaseoli, sp. n. 
Colour piceous, with dense fawn-coloured scaling and ill- 
defined whitish markings; the prothorax with three very 
indistinct paler stripes ; the elytra with the-following whitish 
markings:—the outer margin as far as the eighth stria ; an 
oblique band from the shoulder ending on stria 2 just before 
the middle; a spot on interval 7 a little before the middle ; 
a short line at the base of interval 4; a patch at the top 
of the declivity between striz 1 and 4, bordered in front 
by a dark brown band; and a short stripe at the apex of 
interval 3. 
Head with very coarse confluent punctation, clothed with 
large circular scales and raised, curved, scale-like sete; the 
forehead nearly as broad as the apex of the rostrum, and 
separated from the rostrum by a shallow transverse impres- 
sion; the eyes with a narrow raised rim round the upper 
margin. tostrum thick, gently curved, parallel-sided from 
the base to beyond the middle, the apical portion slightly 
widened; the upper surface with large reticulate punctures as 
far as the insertion of the antenne, with an inconspicuous 
wavy central carina and a less distinct one on each side of it, 
the apical area smooth and with scattered small punctures. 
Antenne testaceous brown ; the scape straight and gradually 
clavate ; the funicle with joint 1 as long as but thicker than 2, 
the remainder short, bead-like, and subequal in length; the 
club broadly ovate, as long as the four preceding joints. 
Prothorax much broader than long, the sides very strongly 
rounded, broadest at the middle, the apex much narrower 
than the base, the latter bisinuate and with a broad median
